Technical details of the Earthcoin network 2019

Technical details of the Earthcoin network 2019
Blockchain parameters
crypt hashing algorithm
Proof of Work (POW) mining
60 seconds block target
Difficulty retarget after each block (+167%, -91%)
Total coins will be 13.5 billion coins (infinite by a theory, because the minimal block reward is 1 EAC, but in the practice 13.5*109 will not be exceeded within the next 2000 years)
50 confirmations per minted block
5 confirmations per transaction
Supports transaction messages
Initial block reward on average 10,000 EAC, varies seasonly ( currently 625 EAC) Block payout is halved every year, minimum payout of 1 EAC per block Superblocks every 14 and 31 day The default ports are 35677 (P2P-network) and 15678 (RPC-calls, optional)
Transaction speed
The mechanism behind Earthcoin which is based on peer-to-peer, allows transactions to happen very quickly. This means that once you pay or get payed with Earthcoin, the time taken to see the money transferred is equal or sometimes faster than the avarege debit card. Earthcoin promotes transaction times of approximatly 30 seconds where it is actually closer to 10-15 seconds which is nowadays regarded as being instant. The true strength behind this speed is the abillity to use it in any store in the near future with the same feel of speed as the currency you hold today.
Security
The Earthcoin network had been attacked by a 51% attack and controlled by a group of hackers for several months in the middle of 2017. Thanks to the unwavering efforts of the community, the attack was thrown back and EarthCoin was returned to all users. The source code was then fixed, secured against similar attacks in the future and a unique protection against time travel attack was implemented. The EarthCoin code is now much more secure than most of other cryptocurrencies. In the first half of 2019, a major upgrade of the Earthcoin network was done and security features according to the current blockchain protocol of Bitcoin and Litecoin networks were implemented.

Acceptance of cryptocurrencies in the world and how's PYRK different

Acceptance of cryptocurrencies in the world and how's PYRK different
Greetings. 👋🏻 Today we will tell you about the acceptance of cryptocurrencies in the world and the advantages of PYRK.
Today, the topic of distributed technologies, including blockchain and crypto assets, is very relevant. The use of cryptocurrencies and blockchain technology has become one of the answers to the opportunities and challenges of the development of the global economy.
Digital currencies are a new stage in the evolution of money. In the digital economy, the functions of money remain the same, but the requirements for them increase:
🔹 transition to cashless (digital) form;
🔹 minimum cost of storing cash;
🔹 maximum unification of technology for the transfer and storage of value;
🔹 the possibility of self-settlement regardless of the location of the sender;
🔹 lack of intermediaries and third parties in settlements and payments;
🔹 speed, convenience and a high degree of reliability of payments.
The crisis of confidence in the existing world order and the current system of state regulation of the economy led to the development of decentralization and the emergence of digital assets, cryptocurrencies.
According to the creators, in order to use cryptocurrency, it is enough to install the client program and create an account to which the electronic wallet will be linked. After that, any owner of a laptop/smartphone with Internet access will be able to exchange payment units with other network users without intermediaries.
📌 PYRK is a privacy-oriented cryptographic currency based on the work of Bitcoin, Dash, and Digibyte. Its distinctiveness lies in the application of the mechanism of the triple Proof-of-Work algorithm, which significantly increases the security of the system.
📌 Also, PYRK uses the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining. MultiShield is designed to let the difficulty "fall" very fast so that the chain doesn't freeze.
Other distinctive features of PYRK:
✔️ NO pre-mining, NO Hidden Blocks, Fair Launch
✔️ Initial block reward = 100 Pyrk
✔️ Descending Reward Reduction every 100,000 Blocks
✔️ Block Time: 90 Seconds
✔️ Max Circulation: 100M Pyrk
✔️ Private send transactions
✔️ Masternodes (Initial collateral 1000 Pyrk)
✔️ Community Fund (Up to 10% of Monthly Mining Reward)

Step by Step Guide to Starting Smart Mining of ViaBTC
In order to help our miners to get the best possible profits, now we present you the step by step guide to starting Smart Mining of ViaBTC. No time for hesitation, try Smart Mining now!
Smart mining consists of two different mining modes, namely as “Manual Switch” and “Auto Switch”.
Auto Switch provides an automated way of profitable mining using the designated algorithm to monitor the real-time status of possible returns. In comparison to manual switch, it’s more flexible and easier to keep tracking of your mining returns.
1.
Enable Auto Switch
It now supports BTC、BCH and BSV, besides, your assets in your account can also be converted into BTC on an hourly basis automatically.
Before enabling auto switch mode, you’re required to configure smart mining URL: stratum+tcp://bitcoin.viabtc.com:3333;
Enable Manual Switch
This supports Bitcoin pool (BTC, BCH, BSV, FCH) and Ethereum pool (ETH, ETC).
One-click switch address is different from the stratum URL for a specified coin. Details for one-click switch URL are listed as following: BTC/BCH/BSV/FCH: stratum+tcp://bitcoin.viabtc.com:3333 ETH/ETC: stratum+tcp://ethereum.viabtc.com:3333 Noted: Port 25 or 443 is available as an alternative option.

Frequently Asked Questions
What is the unique feature of Auto Switch compares to Manual Switch? It’s more flexible and easy to set up, SHA-256 mining algorithm compatible.
How long will it take to be activated after enabling Auto Switch? Once Auto Switch is on, system will monitor the possible return rate of all compatible coins using a designated algorithm and switch to the one with higher profits, you may go to the Pool panel for more accurate mining status.
Why I can’t see my earnings increased after enabling Auto Switch mode? Auto Switch mode demands high-efficiency when it switch between the current mined coins to the new one with possible high returns, specified using designated algorithm and current difficulty, thus it’s not a guarantee pass for high returns when “Auto Switch” is on.
Is there any requirements of MIN. limit of hashrate before enabling Auto Switch? There is no minimum limit of hashrate in your account before enabling Auto Switch in your account.
Which type of coins are supported in Auto Switch mode? Currently all types of coins in Bitcoin Pool are supported in Auto Switch mode, including BTC, BCH and BSV.
When will the mining rewards distributed to my account? Rewards distribution are varies for different mining modes, and distribution time remained unchanged compares to the one in Manual Switch mode.
Can I use part of hashrate to mine a designated coin after enabling Auto Switch? After enabling Auto Switch, hashrate connecting to your account will switch from one to the other automatically using a designated algorithm.
Will I receive hashrate fluctuation notification after enabling Auto Switch? You’re required to set hashrate fluctuation notification for all compatible coins by the time enabling Auto Switch, more detailed guideline can be found here.
How to check your current mining preference?

The Best Cryptocurrency Mining Pools in 2020

This review is not sponsored! Neither it is an ad.
How to choose a mining pool? How to avoid stale shares? The pros and cons of different services.

What is a cryptocurrency mining pool?

A “mining pool" is a server that distributes the task of calculating the block signature between all connected participants. The contribution of each of them is evaluated using the so-called “shares”, which are potential candidates for receiving a signature. As soon as one of the “shares” hits the target, the pool announces the readiness of the block and distributes the reward.
However, if you participate in the pool, then you will have to share the profit with all the participants in the pool, but for the majority, this usually is the most profitable option.

Which pool is better for mining?

The best mining pools should meet the following criteria:

Key selection criteria

To select a good pool for each specific cryptocurrency, you need to carefully study all the information available about it on its website and on the forums.
To reduce the number of stale shares, it is better to mine on the pool closest to the miner. You can choose the fastest mining pool by studying the information about the processing speed of the share in the mining program or by pinging the time it takes for the signal to pass from the miner's computer to the servers of the pool.

Now with the recent halving, does the upcoming Antminer S19Pro make sense?

Hi Bitcoin community.
This is my first post here so I want to introduce myself a bit. My name is Alex, I'm 25 years old, I live in Italy and I've been a Cryptocurrency miner since January 2017. Right now in my small mining farm I have online 2 Innosilicon S11, one Antminer A3 (All 3 mining a Blake2b coin that I've invested in), 4 Innosilicon A10 and from late 2017 till mid 2019 I had 5 Antminer S9 (14Th/s batches) running.
In these days I was thinking if it is worth buying the upcoming Antminer S19 Pro from Bitmain, since as of today (19 May, 2020) with the current difficulty and price, the profit with that ASIC sits around 2,00USD/day (Assuming the power cost is 0,10USD per Kw). Also to keep in mind these new Antminers haven't been delivered yet, so the difficulty will rise even more.
In my opinion, unless the minimum BTC price rises to at least the 20.000-30.000USD range, getting the S19Pro is not a great investment. What do you guy think? I'd like to hear your opinions as well.

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Why coin staking will be added in Ethereum 2.0

A brief educational program for those who do not follow the update of the project of Vitalik Buterin. Ethereum has long been in need of updating, and the main problem of the network is scalability: the blockchain is overloaded, transactions are slowing down, and the cost of “gas” (transaction fees) is growing. If you do not update the consensus algorithm, then the network will someday cease to be operational. To avoid this, developers have been working for several years on moving the network from the PoW algorithm to state 2.0, running on PoS. This should make the network more scalable, faster and cheaper. In December last year, the first upgrade phase, Istanbul, was implemented in the network, and in April of this year, the Topaz test network with the possibility of staking was launched - the first users already earned 1%. In the PoS algorithm that Ethereum switches to, there is no mining, and validation occurs due to the delegation of user network coins to the masternodes. For the duration of the delegation, these coins are frozen, and for providing their funds for block validation, users receive a portion of the reward. This is staking - such a crypto-analogue of a bank deposit. There are several types of staking: with income from dividends or masternodes, but not the device’s power, as in PoW algorithms, but the number of miner coins is important in all of them. The more coins, the higher the income. For crypto investors, staking is an opportunity to receive passive income from blocked coins. It is assumed that the launch of staking:
  • Will make ETH mining more affordable, but less resource intensive;
  • Will make the network more secure and secure - attacks will become too expensive;
  • Will create an entirely new sector of steak infrastructure around the platform;
  • Provides increased scalability, which will create the opportunity for wider implementation of DeFi protocols;
  • And, most importantly, it will show that Ethereum is a developing project.

The first payments to stakeholders will be one to two years after the launch of the update

The minimum validator steak will be 32 ETN (≈$6092 for today). This is the minimum number of coins that an ETH holder must freeze in order to qualify for payments. Another prerequisite is not to disconnect your wallet from the network. If the user disconnects and goes into automatic mode, he loses his daily income. If at some point the steak drops below 16 ETH, the user will be deprived of the right to be a validator. The Ethereum network has to go through many more important stages before coin holders can make money on its storage. Collin Myers, the leader of the product strategy at the startup of the Ethereum developer ConsenSys, said that the genesis block of the new network will not be mined until the total amount of frozen funds reaches 524,000 ETN ($99.76 million at the time of publication). So many coins should be kept by 16,375 validators with a minimum deposit of 32 ETN. Until this moment, none of them will receive a percentage profit. Myers noted that this event is not tied to a clear time and depends on the activity of the community. All validators will have to freeze a rather significant amount for an indefinite period in the new network without confidence in the growth of the coin rate. It’s hard to say how many people there are. The developers believe that it will take 12−18 or even 24 months. According to the latest ConsenSys Codefi report, more than 65% of the 300 ETH owners surveyed plan to use the staking opportunity. This sample, of course, is not representative, but it can be assumed that most major coin holders will still be willing to take a chance.

How much can you earn on Ethereum staking

Developers have been arguing for a long time about what profitability should be among the validators of the Ethereum 2.0 network. The economic model of the network maintains an inflation rate below 1% and dynamically adjusts the reward scale for validators. The difficulty is not to overpay, but not to pay too little. Profitability will be variable, as it depends on the number and size of steaks, as well as other parameters. The fewer frozen coins and validators, the higher the yield, and vice versa. This is an easy way to motivate users to freeze ETN. According to the October calculations of Collin Myers, after the launch of Ethereum 2.0, validators will be able to receive from 4.6% to 10.3% per annum as a reward for their steak. At the summit, he clarified that the first time after the launch of the Genesis block, it can even reach 20.3%. But as the number of steaks grows, profitability will decline. So, with five million steaks, it drops to about 6.6%. The above numbers are not net returns. They do not include equipment and electricity costs. According to Myers, after the Genesis block, the costs of maintaining the validator node will be about 4.75% of the remuneration. They will continue to increase as the number of blocked coins increases, and with a five millionth steak, they will grow to about 14.7%. Myers emphasized that profitability will be higher for those who will work on their own equipment, rather than relying on cloud services. The latter, according to his calculations, at current prices can bring a loss of up to minus 15% per year. This, he believes, promotes true decentralization. At the end of April, Vitalik Buterin said that validators will be able to earn 5% per annum with a minimum stake of 32 ETH - 1.6 ETH per year, or $ 304 at the time of publication. However, given the cost of freezing funds, the real return will be at 0.8%.

How to calculate profitability from ETN staking

The easiest way to calculate the estimated return for Ethereum staking is to use a special calculator. For example, from the online services EthereumPrice or Stakingrewards. The service takes into account the latest indicators of network profitability, as well as additional characteristics: the time of operation of a node in the network, the price of a coin, the share of blocked ETNs and so on. Depending on these values, the profit of the validator can vary greatly. For example, you block 32 ETNs at today's coin price - $190, 1% of the coins are blocked, and the node works 99% of the time. According to the EthereumPrice calculator, in this case your yield will be 14.25% per annum, or 4.56 ETH.
Validator earnings from the example above for 10 years according to EthereumPrice.
If to change the data, you have the same steak, but the proportion of blocked coins is 10%. Now your annual yield is only 4.51%, or 1.44 ETH.
Validator earnings from the second example over 10 years according to EthereumPrice.
It is important that this is profitability excluding expenses. Real returns will be significantly lower and in the second case may be negative. In addition, you must consider the fluctuation of the course. Even with a yield of 14% per annum in ETN, dollar-denominated returns may be negative in a bear market.

When will the transition to Ethereum 2.0 start

Ben Edgington from Teku, the operator of Ethereum 2.0, at the last summit said that the transition to PoS could be launched in July this year. These deadlines, if there are no new delays, were also mentioned by experts of the BitMEX crypto exchange in their recent report on the transition of the Ethereum ecosystem to stage 2.0. However, on May 12, Vitalik Buterin denied the possibility of launching Ethereum 2.0 in July. The network is not yet ready and is unlikely to be launched before the end of the year. July 30 marks the 5th anniversary of the launch of Ethereum. Unfortunately, it seems that it will not be possible to start the update for the anniversary again. Full deployment of updates will consist of several stages. Phase 0. Beacon chain. The "zero" phase, which can be launched in July this year. In fact, it will only be a network test and PoS testing without economic activity, but it will use new ETN coins and the possibility of staking will appear. The "zero" phase will test the first layer of Ethereum 2.0 architecture - Lighthouse. This is the Ethereum 2.0 client in Rust, developed back in 2018. Phase 1. Sharding - rejection of full nodes in favor of load balancing between all network nodes (shards). This should increase network bandwidth and solve the scalability problem. This is the first full phase of Ethereum 2.0. It will initially be deployed with 64 shards. It is because of sharding that the transition of a network to a new state is so complicated - existing smart contracts cannot be transferred to a new network. Therefore, at first, perhaps several years, both networks will exist simultaneously. Phase 2. State execution. In this phase, various applications will work, and it will be possible to conclude smart contracts. This is a full-fledged working Ethereum 2.0 network. After the second phase, two networks will work in parallel - Ethereum and Ethereum 2.0. Coin holders will be able to transfer ETN from the first to the second without the ability to transfer them back. To stimulate network support, coin emissions in both networks will increase until they merge. Read more about the phases of transition to state 2.0 in the aforementioned BitMEX report.

How the upgrade to Ethereum 2.0 will affect the staking market and coin price

The transition of the second largest coin to PoS will dramatically increase the stake in the market. The deposit in 32 ETH is too large for most users. Therefore, we should expect an increase in offers for staking from the exchanges. So, the launch of such a service in November was announced by the largest Swiss crypto exchange Bitcoin Suisse. She will not have a minimum deposit, and the commission will be 15%. According to October estimates by Binance Research analysts, the transition of Ethereum to stage 2.0 can double the price of a coin and the stake of staking in the market, and it will also make ETH the most popular currency on the PoS algorithm. Adam Cochran, partner at MetaCartel Ventures DAO and developer of DuckDuckGo, argued in his blog that Ethereum's transition to state 2.0 would be the “biggest event” of the cryptocurrency market. He believes that a 3–5% return will attract the capital of large investors, and fear of lost profit (FOMO) among retail investors will push them to actively buy coins. The planned coin burning mechanism for each transaction will reduce the potential oversupply. However, BitMEX experts in the report mentioned above believe that updating the network will not be as important an event as it seems to many, and will not have a significant impact on the coin rate and the staking market. Initially, this will be more likely to test the PoS system, rather than a full-fledged network. There will be no economic activity and smart contracts, and interest for a steak will not be paid immediately. Therefore, most of the economic activity will continue to be concluded in the original Ethereum network, which will work in parallel with the new one. Analysts of the exchange emphasized that due to the addition of staking, the first time (short, in their opinion) a large number of ETNs will be blocked on the network. Most likely, this will limit the supply of coins and lead to higher prices. However, this can also release some of the ETNs blocked in smart contracts, and then the price will not rise. Moreover, the authors of the document are not sure that the demand for coins will be long-term and stable. For this to happen, PoS and sharding must prove that they work stably and provide the benefits for which the update was started. But, if this happens, the network is waiting for a wave of coins from the developers of smart contracts and DeFi protocols. In any case, quick changes should not be expected. A full transition to Ethereum 2.0 will take years and won’t be smooth - network failures are inevitable. We also believe that we should not rely on Ethereum staking as another panacea for all the problems of the coin and the market. Most likely, the transition of the network to PoS will not have a significant impact on the staking market, but may positively affect the price of the coin. However, relying on the ETN rally in anticipation of this is too optimistic.

[Weekly Report] BSV transaction fee is lower

[Weekly Report] BSV transaction fee is lower
Dear friends of LivesOne,

As block sizes get bigger and technology improves, BSV community hopes that more people can use the BSV public data ledger to reduce transaction fee.
On May 13, TAAL, the transaction processor, processed a block of 309MB in size, which contains 1178322 transactions, with a total transaction fee of up to 0.788BSV. If denominated in legal tender, the average fee per transaction is about 0.0009 Yuan RMB.

https://preview.redd.it/l5as5227fuz41.png?width=1240&format=png&auto=webp&s=4abcb3767200719104ccdc54167eb74021666587

  • Current rate of BSV transaction fee
In the Bitcoin market, miners participate in blockchain mining with an aim to make profits. However, as the Bitcoin network recently experienced its halving, transaction fees gradually become more important. The future competition will focus on those transaction processors who can handle more network transactions.
At the beginning of this year, MemPool, the leader of BSV mining pool, announced that they would work with Tall and Coingeek mining, bitcoin mining giants,to support enterprise blockchain applications and reduce the transaction fees. The statement marks the birth of a new trend in which mining companies seek more sustainable profit models to ensure their long-term development.
Transaction processor is expected to adjust its BSV transaction fee rates as relevant to respond to market forces. It will be implementing the following changes to transaction fees charged by its cloud computing operations on the BSV network:
  1. A reduction in the transaction acceptance fee (-blockmintxfee) from 1 satoshi/byte to 0.5 satoshis/byte.
  2. A reduction in the relay fee (-minrelaytxfee which is the minimum fee required for double spend protection and for relaying of a transaction) from 1 satoshi/byte to 0.25 satoshis/byte.
  3. In an additional, but unrelated, change the restrictive limit of 25 unconfirmed ancestors will be immediately raised from 25 to 50.

  • Expectation of BSV transaction fee
Many enterprises are exploring blockchain applications to improve their business. These projects are becoming more and more common, but there are some challenges in the application of the public chain. Bitcoin transaction fees are not expressed in legal tender, but in "sat / byte". Therefore, transaction fees in legal tender price will fluctuate with the fluctuation of the price of bitcoin.
TAAL promises to regularly check the lower BSV transaction fees to maintain stable transaction fees in legal tender. Large enterprises usually want to be able to predict their costs, so stable transaction fees are expected to attract more enterprises to use BSV for data applications.
In addition, due to the difficulty in corporate policy and accounting treatment, enterprises do not or cannot show holding digital assets on their balance sheets. Business participants in the BSV ecosystem have recently begun to explore alternate transaction fee models that provide, in fiat currency terms, greater reliability for BSV business applications – including business deals for miners to directly handle a particular application’s set of transactions for negotiated fee rates or development of tools that enable greater fee customization to be offered by miners to applications.
This evolving fee marketplace is new to bitcoin; it was not possible on the Bitcoin Core network due to its smaller block size and significantly higher transaction fees. This new fee marketplace is only recently enabled by BSV’s greater data and microtransaction capabilities. It is expected that this will bring more users to BSV and attract more partners to strengthen its ecosystem.
With the increasing of BSV trading volume, we can also see the further reduction of transaction fee rate. BSV promises an exciting blockchain future. LivesOne's vision is to enable more ordinary people to use better blockchain applications, and lower fee will help LivesOne realize its vision. LivesOne is eager to participate in the future construction of blockchain with you.

Market Analysis on May 11, 2020: BTC is expected to be halved around 5 o'clock on May 12, how should the market go?

Market Analysis on May 11, 2020: BTC is expected to be halved around 5 o'clock on May 12, how should the market go?
[Today's Hot Tips]
1. [Vietnams Ministry of Finance will set up a research team to manage cryptocurrencies]
According to VietnamNews, a research group under Vietnams Ministry of Finance has been established. The group will be responsible for researching and launching policies to manage virtual assets and cryptocurrencies. The group has 9 members, led by Phmm Hồng Sơn, Vice Chairman of the National Securities Commission, and other members from the National Securities Commission, the State Administration of Taxation, the National Bank of Vietnam, the Vietnam Customs and the Vietnam National Institute of Finance.
2. [BTC is expected to be halved around 5 o'clock on May 12]
OKLink data shows that the current block height of BTC is 629872, and there are 128 blocks from the height reduction block of 630,000. It is expected to reduce production at about 5:00 on May 12 after about 20 hours. Note: After the BTC is halved, the block reward will be reduced from 12.5 BTC to 6.25 BTC.
3. 【Croatian Financial Regulatory Authority approves Bitcoin fund】
Croatian financial regulator Hanfa approved a Bitcoin investment fund, clearing the way for the country's first regulated crypto alternative asset fund.
[Today's market analysis]
Bitcoin (BTC)
From the early hours of this morning, BTC fell in a shock. It fell to a minimum of 8260 USDT at 0:45 and then rebounded. And ate the decline around 1:15. Later, the sideways consolidation was maintained, and there was a significant increase around 4 o'clock. It rose from 8590 USDT to 8780 USDT and then oscillated sideways. Now the overall BTC is finishing around 8640 USDT. Mainstream currencies followed the consolidation and reported gains within the day. BTC is currently reported at 8736.70 USDT on LOEx Global, and rebounded by 1.27% in 24h.

Today, May 11, BTC is halved every four years, and tomorrow will officially arrive!
Yesterday morning, mainstream currencies plunged by more than 10%, and BTC retreated from the highest point by 20%. Just like the risks suggested in the previous article, this position and timing are really not buying points but selling points. Fortunately, after the dark cloud topped the K-line the day before yesterday, I made a reminder in "The halving will be fulfilled, BTC is in high volatility, pay attention to the risk of decline". At 7 o'clock yesterday morning, before the market plummeted, there were people fantasy BTC can reach $ 12,000, and as a result BTC fell, mainstream currencies including BSV will follow.
After halving BTC, the mining revenue will suddenly drop by half, and the revenue of 1T hashrate within 24 hours will be reduced from 1 RMB to 0.5 RMB. According to the current price halving, even if there is more than $ 8,000, the miner's revenue is also returned to 312 black swan, and the mining machine with a lot of revenue will be shut down. Therefore, the 117T hashrate on BTC will drop with a large probability. Because the difficulty of BTC is adjusted to 14 days as a cycle, even if half of the hashrate is removed, the income will not be immediately improved. In addition to shutting down the computing power, there is a place to dig BSV or BCH. It is expected that the hashrate of BSV and BCH will continue to rise in the future. After the short-term market decline with Bitcoin, the high probability of hashrate on BSV can promote the possibility that the market will continue to rise.
Operation suggestions:
Support level: the first support level is 8200 points, the second support level is 7700 integers;
Resistance level: the first resistance level is 8800 points, the second resistance level is 9000 points.

What are the benefits of Crypto Mining?

What are the benefits of Crypto Mining?

https://preview.redd.it/q6xfuxvtmjv41.png?width=875&format=png&auto=webp&s=b092bca718f6cba3ae8c327a54952f4e65c7ed25
If you’ve ever heard the word cryptocurrency, then you’ve probably heard about the mining as well. If you still don’t know what cryptocurrency mining is and about profitable, keep reading!
In order to understand crypto mining, you need to fully understand what a cryptocurrency is first. Unlike traditional currencies (aka fiat currency), a cryptocurrency is a digital asset that works in a decentralized way; it does not require a bank or a third-party to operate. Someone can send someone else a cryptocurrency directly without any third-party involved.
The first ever cryptocurrency created was Bitcoin.
Every single cryptocurrency has a blockchain, which is an immutable digital ledger. A single transaction is recorded on the blockchain permanently, which no one can edit or delete it randomly.
A blockchain works by incentivizing miners to confirm the authenticity of each transaction. A person who confirmed the authenticity of the transaction, get the cryptocurrency as a reward.
Since the cryptocurrencies are based on cryptography, the miners need to solve extremely complicated mathematical problems to verify each transaction. They are incentivized to do it because they are rewarded for it.
Anyone can participate in mining from anywhere in the world as long as they have a computer. When the number of miners increases, it allows cryptocurrencies to be more secure. Even if an attacker would want to attack the blockchain network, somehow, an attacker needs to know 51% or more miners. Since the miners are spread around the world, this task is close to impossible and most likely not economically viable.

Types of Crypto Mining

Bitcoin was the first cryptocurrency to introduce the Proof-of-Work (PoW) consensus algorithm, where users have to solve complex mathematical problems in order to process transactions and secure the whole network.
Bitcoin was quite easy to mine at first, and you could do it with your CPU, there was no need for special equipment, and the rewards were huge. However, today, Bitcoin’s mining difficulty has increased considerably, and users need specialized and expensive equipment to mine it.
There are four main types of mining when it comes to the PoW algorithm. There is a CPU, GPU, ASIC, and Cloud mining.
The first three are essentially the same, but they use different parts of your computer. There are some cryptocurrencies specifically created to be mined only through CPU and to be ASIC resistant. Other cryptocurrencies can be mined through all three methods.
Cloud mining, on the other hand, is a process where a user basically pays to rent out a mining machine somewhere else. You don’t have to buy the equipment physically but it is wise to carry out due diligence and research into who and what you are paying for.

Proof of Stake ‘Mining’

With the introduction of the Proof-of-Stake (PoS) consensus algorithm, cryptocurrency mining changed forever. In this case, users don’t have to solve computationally intensive puzzles. In PoS-based cryptocurrencies, the creator of blocks is chosen via random selection or wealth.
Validators in the PoS consensus have to lock up some of their coins as a ‘stake’ and will get rewarded for it.
There are many benefits over the traditional PoW like lower cost and more energy efficiency. Additionally, because PoS encourages users to hold the coin in the wallet, it stabilizes the price a bit more than conventional cryptocurrencies.
Today, you can find plenty of exchanges that support staking, including the most popular exchange, Binance. The safest option, however, is always going to be staking using your own private wallet.

Proof of Formulation ‘Mining’

FLETA has developed the most innovative and newest consensus algorithms known as Proof-of-Formulation (PoF).
This PoF consensus algorithm uses something called the ‘Synchronization Group’, which allows all of the miners to mine in an orderly manner. The generating block time only takes 0.5 seconds, and the observer node checks the irregular blocks in real-time, which prevents the fork and double-spending. Furthermore, FLETA’s PoF algorithm is currently undergoing the patent process through the United States Patent Office (Application Number: 62717695).
The users can easily create a FLETA formulator through the official FLETA wallet. The minimum amount to create a single Formulator is 200,000 FLETA. The blockchain network is operated by FLETA and requires a 6-core CPU or higher.
As you created at least four Formulators, you will be able to upgrade it, which allows you to get 1.3 times more rewards.
Besides creating a Formulator, users can contribute to mining with a minimum amount of 100 FLETA.

Conclusion

Today, various mining methods exist, each with their pros and cons. However, cryptocurrency miners are still craving more convenient (and less costly) ways to earn rewards.
FLETA’s Proof-of-Formulation consensus is not only fast, but it is also highly secure the added layer of protection between observer nodes, formulator, and the synchronization group.
With plenty more to come, in terms of DApp development, games and partnerships, FLETA’s PoF is increasingly becoming the preferred consensus of many developers due to the speed, security and convenience of the platform.

Proof of Drinks: An Open-Source Bitcoin Drinking Game

I’ve developed a new game that is played P2P…
Proof of Drinks: An Open-Source Bitcoin Drinking Game
GAME RULES
Player Types:
1. Includes Drinkers, Buyers, and Sellers 2. Anyone within The Market may play any of the aforementioned roles at any time. 3. Manages BITCOIN PROTOCOL - Block Reward (frequency, amount, halving) - Die Rolls - Drink Pour 
1. Acts autonomously; is not included within The Market. 2. Sells glasses and drinks to Drinkers. 3. Manages PRICE LIST OF GOODS - Glasses (fiat/glass) - Drinks (fiat/oz.) 
1. Acts autonomously; is not included within The Market. 2. Manages MONETARY POLICY - Inflation Rate - Circulating Supply of Fiat 
Items needed:
  1. Copies of GAME RULES, BITCOIN PROTOCOL, PRICE LIST OF GOODS, and MONETARY POLICY.
  2. One six-sided die.
  3. A number of six-ounce measuring glasses equal to the number of players within The Market.
  4. Drinks (alcoholic or otherwise).
  5. Fiat money (or Monopoly money).
  6. Minimum 6 players or so.
Object of the Game:
  1. To learn the mechanics of bitcoin and the economy through drinking and having fun.
  2. The game ends when one or more of the following conditions are met:
    • You run out of drinks.
    • Everyone is tired of drinking.
    • Everyone is tired of playing.
  3. At the end of the game, the person with the highest net worth (fiat + bitcoin) is deemed The Winner.
General Rules and Definitions:
  1. All die rolls are performed in front of all participants.
  2. Bathroom breaks are permitted, however gameplay continues. If a Drinker is in the bathroom during their round, their round is forfeited.
  3. Anyone within The Market may buy and sell anything at anytime.
  4. Round: The procedure for drinking; may or may not result in the production of bitcoin.
  5. Block: A round that results in the production of bitcoin.
  6. Anyone within The Market can propose a change to any rule at any time.
    • If everyone agrees, game play continues with the new rule.
    • If no one agrees, the person who proposed the change may continue playing or quit the game.
    • If some, but not all, agree, then the game may be forked into two separate games (Note: this may cause hurt feelings). The Government and The Bartender tend to both games.
  7. All values (bitcoin, block reward, fiat, etc) are to be rounded to the nearest whole number.
Analogies:
  1. Drinkers = Miners
  2. Glasses = Mining equipment
  3. Drinking = Proof of Work
  4. Die roll after drinking = Mining for the nonce
  5. Drink pour = Difficulty
  6. Bathroom break = Mining equipment maintenance
  7. All drinks and die rolls observed by everyone = Nodes validating
Game Setup:
  1. Designate a minimum of one player to be The Government.
  2. Designate a minimum of one player to be The Bartender.
  3. All other players (minimum 2? 3? 4?) are collectively The Market.
  4. The Government gives The Bartender and everyone within The Market ___ dollars each.
  5. For the first round, everyone within The Market is a Drinker (in subsequent rounds, anyone can step in our step out of the Drinker role).
  6. All Drinkers claim a chair around a table.
  7. All Drinkers purchase a glass from The Bartender at ___ dollars per glass. (Use a 6 oz. measuring glass for ease of pour.)
  8. All Drinkers roll a die; the Drinker with the highest number goes first. Subsequent rounds proceed clockwise.
  9. The Bartender determines the initial Cost of Drinking (fiat/drink).
  10. Determine the beginning Block Reward (50?).
Round Procedure:
  1. Determine the Nonce
    • Someone in The Market rolls a die. The number rolled is the Nonce for the Block.
  2. Determine the Pour
    • Someone, other than the Drinker for this round, rolls a die. The number rolled equals the amount of drink poured (e.g., a roll of “3” means 3 ounces is poured into the Drinker’s glass).
  3. The Drinker drinks the pour, then, once The Market has collectively determined the glass is free of liquid, the Drinker rolls a die. All participants in The Market verify the die roll.
    • If the die matches the Nonce, the Drinker receives the Block Reward! It is now the next Drinker’s turn, beginning again with Step 1 above.
    • If the die does not match the Nonce, no Block Reward is granted. It is now the next Drinker’s turn, beginning with Step 2 above.
  4. Every 10 Blocks, the Block Reward is cut in half.
  5. Once all Drinkers have completed a Round, The Government determines a new Inflation Rate and inflates the Circulating Supply of Fiat accordingly.
    • The Government rolls a die in another room then comes out and announces the result of the die roll. The number of the result is the inflation rate (e.g., if the roll is “3” the inflation rate is 3%).
    • The Government multiplies the Circulating Supply of Fiat by the Inflation Rate and adds this amount to the Circulating Supply of Fiat. The Government can do anything it wants with the fiat created.
  6. The value of each bitcoin (fiat/bitcoin) is determined by members of The Market.
    • For the determination of the Winner at the end of the game, the final value of bitcoin is the last value at which it traded.

Zhuling Chen
It’s always great to hang out in this group. This group means a lot to the Aelf community. It is the first Aelf community and has been there through all the ups and downs in the world. I would like to start with wishing everyone is staying safe at home during the virus outbreak. It definitely has been a difficult time for all of us, but together we can pull through it.
We understand that the situation is quite striking to all of us. But I really believe that the solution to the virus outbreak is about more global coordination and collaboration.
All of you to be assured, our team in different places are all safe and working from home as normal.
The Aelf team in Beijing were among the early ones experiencing the virus outbreak. As everyone was on the way home for Lunar New Year holiday and then experienced a total city lock-down followed by a 40 days’ work from home policy. It was definitely not easy for them, but our team stayed strong, took necessary precautions and focused on work with the right morale. Mappo has recently published some tips on how to work from home effectively based on our experience. Do check it out. Despite not working in the office since February, we have achieved great progress, including launching Aelf 1.0 preview, which is an important milestone in technical delivery and also the roadmap to mainnet launch (which listed out the essential steps for the community to work together to launch a successful public network)
Let's first talk about Aelf v1.0 preview. It is the cornerstone of the mainnet launch. The product itself has all the features that the public network is needed. The codebase has been reviewed and tested rigorously by the team. And a few highlights of how the network would look like:
  1. The code allows a stable and high throughput blockchain network to operate publicly.
  2. For developers, they will love how flexible the system is to be customized, the number of tools and documentation to help them start developing applications on the network
  3. For the whole community, the system is an ever-evolving one where the voting system is ready in place to conduct network-wide voting on various topics, such as transaction fee adjustment, network protocol upgrade, incentive adjustment, etc
  4. Aelf system is able to run multi-chain architecture where each side chain will host different applications and still ready to work with each other
So you may ask since the software is ready, why have we not yet launched the public network? The answer, in short, is that a public blockchain is launched not by a team but through a community effort and that's why we are coordinating the community effort based on the roadmap we proposed. Aelf team has launched the public testnet based on Aelf v1.0 preview and currently, all nodes are under the team. The goal is to let the community and elected nodes to take it over and launch it on a global scale. Not only launch it but also be familiar with the network and also set the launch parameters in a decentralized way. If we take a car as an example, we have made the car, but ultimately the drivers are you guys and therefore before it really hits on the road, we need to guide the community to do a test drive, adjust the car based on what really works for YOU, and ultimately let YOU drive the car freely and safely
So how are we going to help the community launch the network:
First of all, we have launched the codes, documents about the economic system and governance model and technical features. With all the things available, you are able to understand what the system is about, as a token holder what's your benefit in the system, and being a node in the system plays a big role in the governance
Next, without yet electing the nodes, we will get all token holders to join the current Aelf network through a mapping event. That means as long as you have Aelf tokens, you will be able to get 1:1 test tokens on the public testnet. that gives you full access to all the features, and you will feel like you are already using the mainnet. You will get rewarded in making transactions, voting, etc.
Do try out the Aelf wallet and voting features, you will see how easy to transfer tokens cross-chain. and also how flexible the system allows people to make changes. For example, the community may want to adjust the block rewarding parameters or fees to use certain services on mainnet, they can initiate a discussion and then vote in the system and once voted through, it will be reflected on mainnet.
For people or organizations that want to play a bigger role in the system, we will do a dry run of node election. Take it as the real node election before mainnet launch. We will see who the active members of the community are and being trusted by the community. Among the nodes, we will form a network launch committee. The committee will be the crucial party to oversees and ensures the smooth launch of Aelf mainnet, instead of just relying on the Aelf team. This is our step towards decentralization.
The committee will agree on the actual launch process, final checking all the parameters in the system to be ready for launch and then decide when the criteria are met to launch the network. Once all that is decided. We will invite all interested nodes to apply for the election and let the community know what's their plan to grow the Aelf network. the network will initially be launched with a few nodes from the committee and gradually be replaced by the selected nodes (a bootstrap phase). Along the way, we will work with exchanges to conduct token swap (which we are also designing an innovative system to further enhance security and usability of Aelf tokens in exchanges)
Among this isolated and worrisome time, at least we all have something to look forward to: a successful launch of Aelf network! Once it is launched, we are excited to see a vibrant and technically superior network that is good for Dapps to run on top of it.

Doris Guo Q1: As a Blockchain start-up, what difficulties have you overcome when starting Aelf project? What motivates you to solve difficulties and achieve success today?
Zhuling Chen First, just like launching any start-up, its community and investors are usually regional. There is always some bias on if Asian projects are solid. It is really rare to have an Asian project to be supported by western funds and community from day 1. We were lucky to have overcome that obstacle. Having a global investor line-up from day 1. Having a global team from day 1 and also working with a global community from day 1. This benefited us to have an international perspective which is crucial in the blockchain industry.
Secondly, as a hardcore technology company, it is really hard to put in plain words what is our ambition. Our ambition is huge, achieving key innovations in multiple fronts of blockchain technology and organically combined them to serve real users for the future. Our marketing team has been working really hard to elaborate on what Aelf is. Now we have come to a point that the product is ready. Therefore, it is much easier for all of us to understand how solid Aelf is by trying out the network ourselves! That's exactly what the following events will be about - Try out all the exciting features of Aelf network before mainnet launch.
Doris Guo Q2: What critical problems do you see occurring in the blockchain industry nowadays? How does Aelf solve these problems?
Haobo Ma First, we need to distinguish the difference between BTC and ETH. One is Digital Cash and the other is the Smart Contract Platform. Aelf addresses most of the latter's problems. In short, it can be summarized as performance, end-user friendly, developer-friendly, network economy, and self-governance and upgrading. Each of these areas will probably take up a lot of space, and as a whole are the issues described in our two white papers. In short, Aelf is faster, end-users do not need to know the rules of the blockchain, developers can set up the development environment in 10 minutes, have a good economic model and can carry out proposal governance on the chain.
Doris Guo Q3: What is your long-term vision about the industry which Aelf is working at? Are you afraid someday there will be another project with more innovative technology can replace Aelf?
Haobo Ma Let's talk about where Aelf stands in the traditional Internet. It is essentially a cloud service provider, Aelf provides resources and infrastructure for developers to deploy their services, known as smart contracts. We eventually want Aelf to grow like AAA (Amazon, Azure, AliCloud). Because Aelf is a network that can be dynamically scaled, we can accept any new technology, some of the more advanced technologies we can put on a side chain.
Doris Guo Q4: Why did Aelf choose for cross-chain interaction?
Haobo Ma As I mentioned earlier, Aelf solves the Smart Contract Platform problem. However, there are other digital cash problems as well which we would need to use existing infrastructure such as Bitcoin's chain in order to interact with Bitcoin. There are a lot of infrastructures on Ethereum that we want to interact with. Multi-chain on Aelf network mainly is to isolate resources to improve network performance and network stability.
Doris Guo Q5: What difficulties do the Aelf team have now (I talk about COVID-19)? How does the Aelf team solve it? Have you changed the roadmap?
Haobo Ma There is no great impact. The teams in Singapore and Beijing are communicating with each other remotely on a regular basis. The only change is that most of us are now working from home which has no impact and in fact, it seems conducive to the acceptance of more community developers in the future to come. From the internal working schedule and development timeline, there is no great impact. We do not publish specific timeline as we do not want short term holders (traders) to create too much negative pressure on product development.
Doris Guo Q6: Aelf is an open-source blockchain, and there's the common problem of taking a substantial amount of time for the different participants to agree on strategic decisions. What types of governance models do you use in Aelf to address this issue???
Haobo Ma The issue is about public blockchain network, and who can decide the direction of the network. Our answer is long-term holders. For the short-term holders (traders), we refuse to allow them to participate in any discussion of the direction of Aelf because the short-term holders are likely to make a profit and sell quickly, which is essentially the same example of a person who cheats the President and then runs away for his personal gain. We defined a number of proposal processes, including the logic of the two-party system in the United States, and the participation in the referendum to ensure that the final proposal represents the majority. At the same time, we are looking for some legal solutions to avoid bifurcation, such as prohibiting exchanges from intervening in bifurcated new tokens. While we cannot limit a community, we should be able to find ways to limit a centralized organization. This restriction is akin to a ban on national secession.
Doris Guo Q7: How will Aelf empower Investors, Companies, Developers, Platform Users to deliver impactful solutions and bring value to people all over the world?
Haobo Ma We will learn from the operational experience of successful foundations such as the LINUX foundation and license some commercial companies to use Aelf solutions to solve business problems. At the same time, Aelf is an open-source product under the MIT License, and we accept any use that does not violate this open-source principle.
Zhuling Chen Let me add on to Haobo’s statement: to incentivize and empower the community, we are also exploring ways to let the community decide how to use the funds for Aelf (allocate to where it matters to our community) once mainnet is launched. This means you guys can decide what are the projects to be funded on Aelf, etc
Doris Guo Q8:When will the node campaign start? How will Aelf attract users to participate in nodes election?
Haobo Ma According to our published roadmap, the timeline can be dynamic, but I don't think it will be too long. The main idea is to let everyone understand what we envision Aelf to be like, and what are the rights and benefits of being a node in the future. We hope to find nodes that fully recognize the efforts of Aelf at the present stage and are willing to participate in the future development of Aelf. We will run a simulation of the node campaign on the testnet and set up a temporary mainnet launch committee. Please follow our official Twitter for more upcoming details!
Doris Guo Q9: Token swap form 2 is some kind of cross-chain transfer? It will be handled by a smart contract?
Haobo Ma It is handled by the smart contract, we define an asset cross-chain transfer protocol, but it may be opened after a snapshot.
Doris Guo Q10: Which Exchanges will support token swap? Do you have any plan to list Aelf in some big exchange like Binance, Houbi, Kucoin, .......?
Haobo Ma We are already in talks with some exchanges, there is still competition between exchanges, and many are still hoping to attract more users by getting access to mainnet token swap early.
Doris Guo Q11: Aside conversion of the current tokens to mainnet tokens, what other main features will be accomplished with the mainnet launch?
Haobo Ma We have a documentation file that has been published, which has listed some features: https://Aelf.io/gridcn/Aelf_public_testnet_and_supporting_features_introduction_en_v1.0.pdf
Doris Guo Q12: Do you have any plan to burn or buyback your coin?
Haobo Ma We have plans for the community to govern through DAO, we have no interest in short-term price incentive adjustment as we would prefer to drive the project to higher adoption. After mainnet starts operation, there will be a part of network revenue get destroyed automatically.
Doris Guo Q13: Often, as a newbie developer, I face difficulties on most blockchains. How easy and convenient is it for me on Aelf, and what programming language and tools are needed??
Haobo Ma We set up staging for DAPP developers on GitHub and configured CI. Develop a smart contract using C# with React Native on the front end. So, in fact, developers can fork the source code without setting up the environment locally, and you can conduct unit testing with the help of CI. You can also release the smart contract and generate the installation package of iOS and android online. https://github.com/AElfProject/Aelf-boilerplate
Doris Guo Q14: What is the progress of business development and what are some of your commercial partnerships? How will Aelf rapidly develop the number & performance of DAPP?
Haobo Ma First of all, the blockchain industry is still fairly small and users with ETH and EOS wallets are considered a very small group and its not effective to even promote within these groups. What we need to consider is how to enable users who have never been exposed to blockchain to use DAPP. The competitiveness of Aelf is to make it easier for Aelf developers to promote their DAPP to ordinary users, rather than to teach ordinary users a lot on blockchain knowledge. The average user doesn't like to hear about private keys, mnemonic, Gas Price, RAM, CPU, etc. Only until we solve such problems, companies that need to solve problems through blockchain will be more inclined to use Aelf in technology selection. Therefore, our main work is to explain the competitive advantages of Aelf, ETH and EOS to everyone. We have some business cooperation’s, but we also believe that simply through case-by-case business cooperation will not be able to gain adoption so quickly, therefore we still need to put our products to stay ahead of the next generation.
Doris Guo Q15: What other activities can encourage more people to be confident about Aelf?
Haobo Ma We are only going to state the truth by having those that have faith in us to stay and those that don't to leave. The development of Aelf is not driven by a single foundation, but by a steady stream of contributions from the community. In the future, we will also place the activities in the DAO for on-chain governance, and let the community make decisions by itself.

Kun Aguero As you know that in the present market situation many new coins or either dying or thriving for liquidity? How will you manage this liquidity problem?
Zhuling Chen Aelf started in 2017. we have gone through a few cycles in the market, still, remember the big down period in 2018-2019. Aelf is financially solid and the team has always been working hard. if you are referring to liquidity in exchanges, we are among the lucky ones that are listed in all major exchanges
Xinshu Dong Hello, great discussions! I would like to ask what are the criteria to join the committee for launching the mainnet? Would love to participate
Zhuling Chen Hi xinshu, great to see you here. The committee will be chosen among the nodes elected during the testnet dry run. Which means, it is really important to participate in the testnet dry run and also start to establish your reputation in the community so that people will elect you as a node. The detailed criteria will include what is your plan to help Aelf to grow, tech competency and reputation.
An Da What are Aelf’s achievements in 2019? Who had supported you to get those things?
Zhuling Chen To name a few, in 2019, Aelf is one of the most active projects on GitHub. This means Aelf is evolving and improving fast in this space and our team has the tech strength. In addition, we have also successfully listed on all major cloud service providers, such as AWS, Azure, Google. So large companies can easily launch Aelf side chains in their organization with minimum hassle.
John How does the voting for master nodes candidates occur? And why is the development of this system important for your project?
Zhuling Chen Voting is going to be pretty simple. All token holders can vote for the nodes they support on our block explorer.
Miha After mainnet lunch, how will you assure that transactional fees will stay low? We know what sometimes happens to fees on ETH blockchain.
Zhuling Chen First of all, due to the fact that is Aelf is scalability, this will reduce transaction fee. Secondly, all transaction fees will be voted by the nodes (which will be elected by you). So they will represent your interest
Bobbyfernandito Currently, as we see All projects are concerned with the speed and security. So, tell us here - what are the facilities Aelf provide to their user and investors?
Haobo Ma Security: we have an automated smart contract code audit. During contract deployment, production nodes and the community audit participation are required. On the other hand, we are also planning to provide a standardized model of centralized exchange access for 100% asset certification and emergency measures to deal with exchange attacks, which we will be released later. Speed: Aelf has been working on improving performance, which is transparent to users which they can also experience by themselves.
An Da What effect does Aelf token have on the Aelf ecosystem? Holding Aelf, what benefits will users receive?
Zhuling Chen Holding ELF enables you to use all the services on the Aelf network. ELF has a deflating system where the total amount will reduce as the network grows. token holders can also vote for the nodes to run the network and also vote for big decisions in the network. part of the fees in the system will also be distributed to token holders via a smart contract
ahihi132 Which companies do you view them as potential partners and that they are somewhat also beneficial for both the user base and Aelf itself?
Zhuling Chen Great question, if I could write a wish list, that will be: let medium-sized financial institutions to use Aelf to challenge the big boys. Let telecommunication companies use Aelf for micro-payment and other innovative business models. We also would like to try out a few public sector projects, which blockchain will is still more transparency and trust
Misun Q1: Which programming languages are you using in your project? And why? Q2-What are another big MILESTONES you have planned for 2020 roadmap and how are they supposed to benefit your costumers? Will it be an exciting year?
Haobo Ma For Q1: We mainly use C# for development, I personally like it. Performance is good, development environment IDEs are strong, and C# creators are influential in the industry. We believe in the right thing, though it may take a while to develop. The smart contract will then add support for multiple languages, such as WebAssembly, depending on the needs of the community. Now it seems that C# is enough.
Hambi crypto Which platforms are your competitors? How will you soar above them, and what better things do you offer than them? So, What’s your outlook on the future of cryptocurrencies in this year and next few years?
Haobo Ma As I have already mentioned this before, Eth and Eos. We provide better performance, cross-chain support (already implemented), end-users do not need to know the details of the blockchain, developer’s payment models and so on.
Floris-Jan What plans is Aelf making to prevent centralized exchange to take over the DPoS algorithm like what happened to Steem? Are we talking about blacklisting exchange wallets, or having the foundation say "No", or putting all trust in the community?
Zhuling Chen Great question, Floris. I’m not going to give away all the details of what Haobo has proposed to work on this, but in a nutshell, in Aelf system, exchange wallets will not be allowed to vote, but only the sub-wallets for each individual can vote. This will also help exchanges to prevent hacking and theft in the future
Alex What your plans in place for global expansion, are Aelf wallet focusing on the only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Can you explain this?
Haobo Ma Our core focus will be through the developers to promote, developers will help Aelf to attract more users. So our product has to be attractive to developers. Just like AWS, they only focus on getting their service right, their developers will think about how to promote it. We don't want to burden them in their promotion process.
Ellkay What do you think are the major threats and barriers that could face the development and adoption of Aelf?
Haobo Ma If I'm a DAPP developer and I need to promote my APP to people who don't recognize blockchain, then I'd like to choose a platform that doesn't have to explain a lot of blockchain details to the end-user, so they can use it easily. We've provided some options in the Boilerplate that allow you to log-in simply via QR code + Password, and our recommended Dapp is an independent wallet and a separate iOS/Android application.
ahihi132 Give me some important reasons why we need to hold Aelf token where in fact hundreds of projects failed and it went to bankruptcy or even developers run when they collect millions/billions of funds?
Haobo Ma First of all, we will not give any suggestions as we only describe the fact that the long-term token holder will be able to govern the Aelf network, get Aelf mining reward and Aelf network profit. At the same time, Aelf network is a deflation model, Aelf network received transaction fees, profit dividends will immediately destroy 10% etc. All investments are risky, and we don't judge the behaviour of other developers. There are so many things in this world that cannot be understood and unfair. It is important to do our job well. I cannot explain these things.
见愁 I remember that boss Ma mentioned to only find those truly innovative applications and enterprises with blockchain, how to find and win partners in these aspects?
Haobo Ma When Linus was developing Linux, I did not think he would find a lot of collaboration when the code was not good. The response we can give is that we already have a lot of interest in cooperation, including what we have announced, what we have not announced, etc.
见愁 How interested are cloud computing providers in participating nodes?
Haobo Ma The vast majority of our nodes should be using cloud services, and as long as a large number of our 17 nodes and other candidate nodes are based on cloud services, our network robustness is determined by these cloud computing providers. Of course, in the expansion, we can also use cloud computing services.

Decred: Our Network Issue #2 - 4 Year Review

Decred: Our Network Issue #2 - 4 Year Review
Decred is approaching it's fourth Birthday on 8-Feb-2020 and to celebrate, the submission to the Our Network Newsletter will be covering an array of achievements by the Decred chain to date.
The Our Network newsletter is an industry wide publication driven by community members with a focus for on-chain data and behaviour of crypto-networks. Decred is featured once a month alongside other L1 networks Bitcoin, Ethereum, ZCash and Tezos.
https://ournetwork.substack.com/about?utm_source=subscribe_email&utm_content=learn_more

Insight 1 - Total Value Settled

Decred has finalised over $11.44 Billion in USD denominated value over its lifetime, accounting for the movement of over 409 Million DCR units. A dominant component of these on-chain flows comes from DCR tickets (~50%), which represent long-term holders participating in PoS security and governance.
Cumulative value settled in USD and DCBTC units

Insight 2 - Growth of Decred Mining

ASIC hardware was first released for Decred in Janurary 2018, approximately two years after launch and at the peak of the 2017-18 bull run. Decred hashrate has grown by 1,000x following ASICs coming online. Given the prolonged bear market, the Difficulty ribbon is currently squeezed although showing early signs of recovery.
Interestingly, the acceleration in hash-rate growth and subsequent squeeze/plateau of the difficulty ribbon are reminiscent of Bitcoin throughout the the 2015 bear market.
Growth of PoW mining hash-rate and difficulty.
Insight 3 - Stakeholder Commitments
Decred is unique in that it supports both Miners and Stakeholders with coins continually circulating via DCR Tickets. Observing the aggregate behaviour of both parties shows each create fundamental support/resistance levels during price discovery.
  • A cumulative $5.6B has been locked in DCR tickets and this commitment line (green) has been a magnet for price in a Bull Market.
  • The cumulative reward paid to PoW miners (incl. fees) now totals $147M and supports the notion that miners support bottoms for Bear Markets.
  • The Realised Price acts as a dynamic support and resistance line in response to changing ticket flows in Bull/Bear conditions.
  • The Realised Cap is currently squeezing against the PoW Miner line, an event last seen in early 2017.
Stakeholder commitment channel showing fundamental support and resistance by stakers and miners.

Insight 4 - Treasury Expenditure

The Decred Treasury is a central component of Decred's value proposition, enabling sustainable and self-sovereign development into the future. The treasury receives 10% of the DCR block subsidy for deployment by DCR stakeholders.
To date, the Decred Treasury has accumulated over 639,600 DCR, equivalent to $11.5M at $18/DCR. The project has a spend ratio of 32% of inflows to-date and 14% of the final inflow of 2.1M DCR, at the end of the block subsidy. Pricing all Treasury expenditure outflows on the day of the transaction, the Decred treasury has spent $6.96M USD to bring the protocol from genesis to its current state.
Treasury Balance, inflow and outflow in DCR and actual spend rate

Insight 5 - Decred Consensus Change DCP0005

Decred is currently undergoing its fifth on-chain vote to upgrade the consensus rules. The DCP0005 change restructures block headers and filters to improve SPV security and optimise the interaction between PoS votes and PoW miners.
The DCP0005 codebase lies dormant in the new node software and now that 95% of Miners and 75% of Stakers have upgraded, the vote to activate it is live. A minimum quorum of 20% of Stakeholders must vote with 75% consensus to activate the new code. The current approval rate has 99.94% of tickets voting Yes, out of a 59.68% participation rate (note that abstain is default and only yes/no votes count as participation).

New-ish Player's Guide++

I did a guide a month ago for new players here, this guide is a continuation on that: https://www.reddit.com/EscapefromTarkov/comments/e9smrv/new_players_guide_extended/
If this is your first week, this games amazing and worth it. In the meantime read this guide to start:
https://www.reddit.com/EscapefromTarkov/comments/e515ub/influx_of_new_players_means_its_time_for_a_guide/
I wanted to do a follow up guide after doing ~30ish runs on each map this month to get the current meta of each and review various armors because I'm slightly bored after all the quests and max hideout is done but this game is just too addicting to stop playing. It also helps that I've had 8 friends buy the game in the last few weeks so this is easier than explaining to them one at a time. If anyone sees anything incorrect please feel free to correct me and if there's any other questions post in comments/pm me.

General Tips Continued:

Maps

TLDR: Shoreline for money, Interchange for consistency, Customs for quests, Factory/Labs for fights.I did a brief overview on money runs on various maps in my previous guide, but wanted to update those maps in light of recent changes to spawns and my experiences over the past month or so testing all the maps out. In profitability order:
Shoreline - With the new addition of 6-8 LedX spawns, shoreline has become king for money. It takes the high reward possibility of Labs and mixes it with the consistent loot value of Interchange with the only draw back being the need for keys, which I purchased for around 3-4 mil for all good loot rooms ( 15 keys in total). This is a steep investment, but it is a one time cost, and completely worth it. You can expect an LedX about 1/7 raids clearing most LedX rooms. I got 5/36 shoreline runs, clearing most rooms about 2/3rds of the time, dying or being beaten to the rooms in the other 1/3. Unlike labs, however, these are just the cherry on top of consistently amazing loot in the rooms with easy extracts to boot. The big draw back is popularity, I run into at least 2-3 PMCs at the resort, usually 4-5 with a duo or squad tossed in the mix. They're usually tier 3-4 geared (I go tier 5 but don't recommend that unless you're good with losing a mil to a lucky mosin shot) and have a bad habit of hiding in rooms and ambushing.
Interchange - For consistent mid value barter items, Interchange is your map. Nothing has changed from my original assessment, tldr version being run Oli shelves and the 3 tech stores next to it for about 500k-1 mil per extract, assuming you bring a decent bag and rig. This map has dropped in popularity with the Shoreline buff, but be on the look out for tier 5 geared PMCs doing their 100 Killa kills grind and the ever present extract campers.
Reserve - This map still has great high value drops, less frequent than Interchange but with higher average value and requiring less keys than Shoreline. The massive drawback here is extract difficulty. If you can afford it, para-cord with the ice-pick for the repel extract is recommended as you just have to ditch/bag chest armor and you're out. Losing a bag for the manhole has required many a painful pick and chose for me recently and the door just isn't consistent, sometimes the button will be pressed but its still locked, other times its just open. Its a fun PvP map, but for money its just not beating the two above.
Customs - This map just really isn't for money, its for quests. But with the addition of the new stashes spread throughout the map you can make decent money whilst running the quests. See my past guide/the link below for stash runs.
Factory - Wait, Factory over Labs? Customs over Labs? Yes, I'm getting to that. So why Factory? Because quick, hit and run style or longer scav pileup at a choke-point style runs can net you tons of experience along with a big stack of weapons and decent loot from scav pockets. Solos try the upper hallway office/breakable door, the bottom pipeline hallway curve, or extract choke-point. Duos and squads can hold down the shower doors with ease.
Labs - People who have read my previous guide might be surprise this is last. The issue with labs is its completely dependent on high level item spawn rates. Labs is my favorite map, I could write a lengthy separate post about everything labs. At the beginning of the wipe, labs was ludicrously OP. You could spawn in and expect a 1/3 chance of an LedX (2.5 mil at the time) along with 2-3 other 400k+ items spawning in each raid. This resulted in 10's of millions in profit. Then they released Shoreline LedX spawns and turned off labs LedX. The barrel spawn was completely dead (50+ runs and nothing) and the two other (at the time) known locations had maybe a 1/25 rate. You could expect maybe 1-2 other drops per raid and it was now crowded with PMCs. It was difficult to turn a profit doing geared runs, and I lost millions. Today its slightly better, there are 3 new LedX spawns and the barrel spawn has a 1/7-10 (still testing) rate but everything has plummeted in price (VPX is less than 200k now) and you can expect 3-6 tier 5 geared PMCs plus raiders to be skulking around. Great for fights, terrible for money. Though extracting will often bring huge rewards in gear alone in current state.
... - Feel like I'm forgetting one... Hmm... Nah they wouldn't put a thermal ridden snipe happy map in the game with no loot spawns and lots of annoying quests. (Don't @ me Woods fans)

Armor

TLDR: Highest level armor not worth, high level ammo makes everything vulnerable. Not doing the same tiers (see previous guide) but the actual armor level itself. For actual setups with armoweapons see my previous guide.

Does this mean you should never run good armor? No. What it means is you should be aware you are likely losing value/money by doing so at higher tiers. Better armor will help you survive more raids, help with quests, and is a sign of being a more established player. But you are trading a LOT more money for smaller advantages in return, making it hard to recommend the more expensive armors in the game to anyone who can't handle multiple instant deaths in a row losing 500k-1mil.

How Bitcoin Can Be Hacked. One Way to Do it. (Not clickbait)

I refer to this post at https://www.reddit.com/ethfinance/comments/e52zyc/vertcoin_network_sabotaged_by_another_51_attack/.
There is something we can learn from this event. Vertcoin is a fork of Bitcoin protocol. So by right, technically, if Vertcoin can be attacked successfully, so can Bitcoin. Although maybe nobody have yet to figure out the way, sometime in the past I have a rough idea on how this can be made possible. While Vertcoin was successfully attacked by way of having more than 50% of its hashing power, the same requirement may not be necessary with Bitcoin, as we understand the longest chain takes precedence to become the main chain. So the question is, how can an attacker successfully reorg the Bitcoin chain cheaply, without having majority hashing power, and still be able to create the longest chain?
Theoretically, I can think of one approach. Here's how I think it is possible.
  1. An attacker (with full node of Bitcoin blockchain for all its historical data) process his mining offline, while continue to maintain the full node online, for most current data feed purpose.
  2. With this offline chain, the attacker possesses 100% of all the hashing power with no competition. Of course, this offline chain will still have all the actual historical record of all Bitcoin transactions details.
  3. With this 100% hashing power, the attacker identifies which block to reorg (no matter how old this block is) and re-mine all the blocks starting from there, offline, for their hashes.
  4. As he is the sole miner in his own offline chain, he will be able to overcome the mining difficulty and obtain all the hashes of all the blocks that will be reorged, up to the latest block.
  5. The attacker proceed to do multiple of his own transactions (offline, of course) beyond the most current transactions that are being done on the online chain, to obtain all the necessary hashes of his transactions.
  6. With all the hashes he found from reorg-ing his offline chain, he returns to the online chain that everyone is in, introduces all the hashes from all the way back to the block he intends to reorg up to the latest, plus further transactions of his own (already done offline, with all the needed hashes), and create the longest chain.
The idea is to take the mining difficulty offline (to make it manageable by eliminating miner competition by being the sole miner), figure out all the hashes of all the reorged blocks, offline, return to online mining, reorg the online chain by introducing all the new hashes found from offline mining to the online chain, and maintain the reorged chain as the longest chain to supplant the actual online Bitcoin blockchain.
Theoretically, with sufficient resource and expertise to do it optimally, the effort to reorg should be cheap, fast, and easy to implement, without the need to possess 51% mining power.
One constraint is that the attacker needs to mine his offline chain concurrently and in parallel with the online chain because he needs to keep track of the latest transaction details committed on the online block, to reorg them offline for the reorged hashes, that he will introduce online.
To be able to mine (or reorg) his offline chain concurrently and in parallel with the online chain, he will need a smart algorithm for that concurrency and parallelism. Such need for concurrency and parallelism is important NOT to reorg the chain, but to successfully supplant the actual online chain with the attacker's own newest transaction blocks for the longest chain.
Why a 51% hashing power is not necessary?
As mining is all about brute force + a lot of good luck, a miner does not necessarily need to have 51% hashing power to successfully mine a block, otherwise all small miners would die out already by now.
All he need is just damn good luck at the right time for that split second advantage (or maybe just 10 minutes minimum) to supplant the actual chain with his reorged chain successfully.
No need to have 51% mining power. And no need to have multi million budget to do it.
Disclaimer: My approach is just a theory.

5 cryptocurrencies to invest in 2020

5 cryptocurrencies to invest in 2020

https://preview.redd.it/pzn1ho8cj9i41.png?width=1500&format=png&auto=webp&s=90ee62c6b9271813506ba4cf2b526d16ec285f12
There is no doubt that 2020 will be an important year in the history of cryptocurrencies:
the next halving of BTC, the arrival of the ETH 2.0 era, the possible launch of the token of the Central Bank of China and Europe, the new presidential elections in America, the intense situation in the Middle East …
In the face of the great economic instability, a question that continues to haunt the investors is: What should I buy?
If you have not found a good answer, it is worth paying attention to these 5 cryptocurrencies:
TOP1: Bitcoin
https://preview.redd.it/xtxw64xdj9i41.png?width=1053&format=png&auto=webp&s=4868e166e42c3dd32299acc6d263fad803c753e0
Completing 11 years in the market, Bitcoin currently dominates 70% of the cryptocurrency market.
The reasons to invest in BTC in 2020:
1) Another halving is coming
The 3rd BTC halving will take place in May 2020, which may drive the price to a new level:
The halving will result in a decrease in BTC production, which will lead to an imbalance between supply and demand in the market and drive up prices.
The halving will increase the difficulty of mining Bitcoin and reduce the profit of it. In this sense, miners always bull the market, as the price increase can make up for the entire industry’s losses. While the mining giant has accumulated huge wealth during the BTC dividend period, it will become a guarantee for the rise in BTC prices.
The expectation about halving has become a consensus, and the public’s fear of missing out in the market will drive prices up. It is worth noting that the halving of BTC does not necessarily occur at the time of halving. Based on the previous two experiences, the boon will be released before the halving.
Therefore, You can start to build your position in Bitcoin at an early date, wait for the maximum to arrive and sell at the right time to reduce the risk.
2) Financial havens
Weiss Crypto Ratings considered Bitcoin as the ultimate digital safe haven, whose value will grow in the face of the instability of the international scenario.
Geopolitical conflict. Since 2020, the global risk aversion has greatly increased due to tensions in the Middle East.
Concerns about the global recession: Bitcoin has grown 16% in 2020, and gold has reached its highest price of $ 1610 during the past seven years.
TOP2: BCH
https://preview.redd.it/cbg9ymkgj9i41.png?width=1051&format=png&auto=webp&s=e8a3df0abd8e0660a8bf706571c01fa76d0238d7
BCH is a token derived from BTC during the hard fork process, so its price has a great correlation with the price of Bitcoin.
The height of the BCH block is slightly higher than the height of BTC, so the BCH halving will arrive on April 6, 2020.
Top3:BNB
https://preview.redd.it/4qm7axeij9i41.png?width=1050&format=png&auto=webp&s=005ecf56879e59fa26fbfb62afc6428893be1efb
The year 2019 was considered as a year of bomb for exchange tokens, among which some achieved incredible performance and are among the 20 most valued cryptos in the world, as investors considered them as the most guaranteed cryptocurrencies.
And BNB is a “potential stock”:
Its price multiplied 8.5 times and its capitalization value rose from 861th place to 8th place, as a result of the launch of the IEO (Initial Exchange Offerings) model by Binance in 2019.
Entering the market with a price of $ 0.10 in July 2017, BNB reached its highest increase in June 2019 with a price of around $ 39.57.
Hold for two years = 388 times profit!
In 2020, the value of BNB will also increase with the growth of Binance.
Top4:Tezos
https://preview.redd.it/rg6y11ikj9i41.png?width=1061&format=png&auto=webp&s=93c793ad1c62c9b6f62e2a46f6358f54dca7f9ae
Tezos is one of the public chain projects that managed to survive the fierce competition in the market.
In June 2017, the Tezos project raised $ 232 million during its initial coin offering (ICO), the largest funding among all ICO projects at that time.
In October 2019, Tezos continued to rise, from a minimum price of $ 0.74 in October to a maximum of $ 1.85 in December, an increase of more than 160%, ranking among the top ten by market value.
The reason behind this is that Coinbase has launched staking support for Tezos, which represents the affirmation of the Tezos project, as Coinbase has always been known for its strict project review.
Compared to the highest value of $ 12, Tezos still has a long way to go. Given its reversal in 2019, it deserves attention in 2020 so as not to miss good investment opportunities.
Top5:Maker(MKR)
https://preview.redd.it/j9ch8wumj9i41.png?width=1051&format=png&auto=webp&s=246a2a06ff16e62e7684b2ef1e0fb061017bba77
In 2019, Defi (Decentralized Finance) has become a new hotspot in the blockchain and is considered a “new financial revolutionary movement”.
Maker is the “central bank” of the DeFi lending market, with a market share of over 49%. Those who cannot obtain a loan from the traditional banks can borrow digital assets on the Maker platform. At present, the stable currency DAI is the main borrowing asset, accounting for 74% of the total loan amount, and DAI is the stable currency issued by the Maker platform.
The DeFi market has achieved continuous growth in 2019. According to DeFireview data, as of December 24, 2019, the total locked position reached 796 million U.S. dollars, of which Maker accounted for 39.16%. Compared with January, it has increased by nearly two times, and on June 25, it reached to the highest total amount, which is $ 1.72 billion.
MKR is the token of the Maker system. With the growth of the Defi market, MKR has risen steadily by 12% since the beginning of this year. The market value of MKR jumped to the top 20.
In 2020, with the centralized exchanges starting to launch Defi business and the huge potential of the lending market, the prospect of Maker is exciting.
Keep in mind that investing in cryptocurrencies is always risky, and investing in only one cryptocurrency will face greater risks.

How Bitcoin Can Be Hacked. One Way to Do it. (Not clickbait)

I refer to this post at https://www.reddit.com/ethfinance/comments/e52zyc/vertcoin_network_sabotaged_by_another_51_attack/.
There is something we can learn from this event. Vertcoin is a fork of Bitcoin protocol. So by right, technically, if Vertcoin can be attacked successfully, so can Bitcoin. Although maybe nobody have yet to figure out the way, sometime in the past I have a rough idea on how this can be made possible. While Vertcoin was successfully attacked by way of having more than 50% of its hashing power, the same requirement may not be necessary with Bitcoin, as we understand the longest chain takes precedence to become the main chain. So the question is, how can an attacker successfully reorg the Bitcoin chain cheaply, without having majority hashing power, and still be able to create the longest chain?
Theoretically, I can think of one approach. Here's how I think it is possible.
  1. An attacker (with full node of Bitcoin blockchain for all its historical data) process his mining offline, while continue to maintain the full node online, for most current data feed purpose.
  2. With this offline chain, the attacker possesses 100% of all the hashing power with no competition. Of course, this offline chain will still have all the actual historical record of all Bitcoin transactions details.
  3. With this 100% hashing power, the attacker identifies which block to reorg (no matter how old this block is) and re-mine all the blocks starting from there, offline, for their hashes.
  4. As he is the sole miner in his own offline chain, he will be able to overcome the mining difficulty and obtain all the hashes of all the blocks that will be reorged, up to the latest block.
  5. The attacker proceed to do multiple of his own transactions (offline, of course) beyond the most current transactions that are being done on the online chain, to obtain all the necessary hashes of his transactions.
  6. With all the hashes he found from reorg-ing his offline chain, he returns to the online chain that everyone is in, introduces all the hashes from all the way back to the block he intends to reorg up to the latest, plus further transactions of his own (already done offline, with all the needed hashes), and create the longest chain.
The idea is to take the mining difficulty offline (to make it manageable by eliminating miner competition by being the sole miner), figure out all the hashes of all the reorged blocks, offline, return to online mining, reorg the online chain by introducing all the new hashes found from offline mining to the online chain, and maintain the reorged chain as the longest chain to supplant the actual online Bitcoin blockchain.
Theoretically, with sufficient resource and expertise to do it optimally, the effort to reorg should be cheap, fast, and easy to implement, without the need to possess 51% mining power.
One constraint is that the attacker needs to mine his offline chain concurrently and in parallel with the online chain because he needs to keep track of the latest transaction details committed on the online block, to reorg them offline for the reorged hashes, that he will introduce online.
To be able to mine (or reorg) his offline chain concurrently and in parallel with the online chain, he will need a smart algorithm for that concurrency and parallelism. Such need for concurrency and parallelism is important NOT to reorg the chain, but to successfully supplant the actual online chain with the attacker's own newest transaction blocks for the longest chain.
Why a 51% hashing power is not necessary?
As mining is all about brute force + a lot of good luck, a miner does not necessarily need to have 51% hashing power to successfully mine a block, otherwise all small miners would die out already by now.
All he need is just damn good luck at the right time for that split second advantage (or maybe just 10 minutes minimum) to supplant the actual chain with his reorged chain successfully.
No need to have 51% mining power. And no need to have multi million budget to do it.
Disclaimer: My approach is just a theory.

Bitcoin blockchain records mining difficulty record Bitcoin mining difficulty reaches new high Bitcoin Mining Difficulty Hits Record High of 17.3 ... Bitcoin Miners Hodl More As BTC Trades Sideways Ahead of Difficulty Why Is Bitcoin Mining So Competitive - D-Central

*Based on current mining difficulty and Bitcoin price. View historical difficulty for BCH and BTC ** Daily fee covers electricity and maintenance costs.The contract will end if the total revenue from the past 30 days is less than the total daily fee for the same period. Maximum, current and minimum difficulty []. Current difficulty can be found out by using Bitcoin command line 'getDifficulty'. Due to target function not having minimum value maximum difficulty can be calculated only approximately as following: maximum_target / 1 (as 0 would lead the equation to being infinitely big) which is an inconcievable number (~2 to the 224). Bitcoin Difficulty change = 1.05 + 0.703 x Bitcoin price change. In other words, in the past the Bitcoin difficulty has increased 97.6% on average over 90 days without any Bitcoin price change The minimum proof-of-work threshold required to mine a block. A higher number means more Hash Rate is required to find a block in an average time of 10 minutes. Before the Aug 1, 2017 Bitcoin Cash (BCH) fork, Difficulty was re-calculated every 2016 blocks. Bitcoin mining difficulty determines how difficult it will be to mine the next block and this is why it is referred to as the difficulty of Bitcoin mining. Bitcoin difficulty is a measure of how many hashes (statistically) must be generated to find a valid solution to solve the next Bitcoin block and earn the mining reward.
