TPS test of Ethereum private chain

1. Minerhub's wondermole system is a "diskless" mining system based on Linux kernel, which is deeply customized for miners' friends

solve the problem in an all-round way

1. Miracle Moore's Linux kernel has been deeply optimized for more than 200 times to avoid the problem that some hardware failures will directly lead to system crash
2. In view of the situation that many mining software in the market can't connect to the mining pool after restart, miracle Moore perfectly solves the problem by using the function of resetting the image after each restart of the mining machine
3. After testing, the average computing power error and delay share of miracle Moore system in each mine pool are not more than 1.5%, which significantly improves the mining revenue of users
4. After numerous experiments, miracle Moore development team has obtained the optimized VBIOS overclocking setting of graphics card. Compared with the traditional overclocking method, it can further improve the computing power of graphics card by 5% and rece the power consumption by 15%!

2. The digital currency

issued based on Ethereum public chain should be observed according to the price trend of the platform.

3. This needs to be recharged, but we must pay attention to the risk. This chain is not particularly mainstream. It may be the capital disk or counterfeit currency.

4. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

If you want to query the transaction records on the main network, you can use Etherscan. However, if you build your own private chain, how should you query the transaction records

the answer is that you need to listen to the logs on the chain, save them in the database, and then query them in the database. For example:

< pre t = "code" L = "Java" > varaddr = & quot& quot;< br />varfilter=web3.eth.filter({fromB lock:0 ,toBlock:' latest', address:addr });< br />filter.get(function(err,transactions){
transactions.forEach(function(tx){
vartxInfo=web3.eth.getTransaction(tx.transactionHash);
/ / at this time, the transaction information txinfo can be stored in the database
})< br />});

Web3. Eth. Filter() is used to monitor the log on the chain, and Web3. Eth. Gettransaction() is used to extract the information of the specified transaction. Once the transaction information is obtained, it can be stored in the database for query

6. Ether clown is a new type of blockchain pet game. It's very simple. The clown can eat, grow and earn money by working. The key point is that it can breed all kinds of clowns with strange shapes to make money. Registration is also simple. First register the Ethereum account, buy ether coin, and then enter the fire coin network to trade with coins, and exchange them into my digital wallet, After that, you can use Qianbao to buy clowns. You can have a try. At present, blockchain is a big trend!!

7. Wait, Ethereum is a public chain. Do you mean the token issued above? You can set the total amount

8. Build / env.sh go run build / ci.go install. / CMD / geth
make: * * [geth] error 1
there is no such directory, or the directory has insufficient permissions

9. This is not very clear, because the research team in the central bank's digital currency is generally the relevant personnel of the central bank departments and their think tanks. As early as 2014, domestic banking institutions began to study digital currency
at present, the central bank's research on digital currency is still at an early stage, and it only plans to launch digital currency, but it is still far away from issuing digital currency. When the central bank studies digital currency, it may study the existing mainstream digital currencies such as bitcoin, Ruitai, dogcoin, etc.
