Transaction volume of Ethereum Chuangshi block

1.

Ethereum is the next generation of cryptography ledger. It intends to support many advanced functions, including user issuing currency, intelligent protocol, decentralized transaction and what we think is the first fully decentralized autonomous organization (Daos) or decentralized autonomous company (DACS) application

Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing complete scripting language, which allows you to write code for the feature you want to implement through a mechanism called "contract". A contract is like an automatic agent. Every time a transaction is received, the contract will run a specific code, which can modify the data storage inside the contract or send the transaction. Advanced contracts can even modify their own code

Ethereum was launched on November 1, 2015, and launched on August 22, 2016 on bitcoin trading platform, a well-known domestic trading platform; 30-¥ About 60, current: ￥ 1259.97, the rise is amazing

2. GBK
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum. The concept of Ethereum was first inspired by bitcoin by vitalik buterin, a programmer, between 2013 and 2014, and now it's 2.0. Ethereum 2.0 is also something that the whole coin circle is waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1, chinacoin officially supports the exchange of eth2.0 verification nodes at 17:00 Hong Kong time on November 20, 2020. It will invest its own eth in the verification node mining and exchange qeth to obtain liquidity. It will participate in the mining as soon as the exchange is received. Now it will give back to the user's welfare. The top 1000 eth enjoy the over exchange of qeth according to the ratio of 1:1.02. Compared with eth2.0, qeth has too many advantages: liquidity is guaranteed, users do not need to bear the technical cost, the threshold of participation does not need 32 eth, as low as 0.1eth, nodes are maintained by the platform, and the revenue is distributed according to eth2.0< br /> < br /> < br /> 

3. 2020 is the first year of proction rection. Everyone turns to BTC, BCH, BSV and other currencies. However, you forget eth. As the king of the public chain, ETH will usher in the big upgrade of 2.0 super version in 2020, switching from the pow mechanism to the POS mechanism. In addition, it will face proction rection in March next year, and its circulation will be reced by 10 times. Its impact is no less than that of bitcoin proction. Since the beginning of the year, the trading volume of eth has grown explosively, and the institutional capital has poured in to preempt the layout. However, the current price of eth is only 260 US dollars. With many super favorable blessings, the market expects eth to usher in a super bull market< In theory, the circulation of next year will be reced by 10 times. In theory, the current price of eth is 260x4 = US $1040 (upgrade + expected price after proction rection)

ring this period, the return comparison between holding spot and ETF fund is as follows:

1. Holding spot makes 4 times of profit
2. Holding Ethereum ETF fund makes 12 times of profit, Up to 30 times (intelligent position adjustment + fund compound interest calculation)

there is no doubt that the Ethereum ETF launched by bitoffer is the best investment choice!

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

5. Search Ethereum blockchain browser or bitcoin blockchain browser. If it is based on other chains, search other browsers to view

6. At present, the concept and construction mode of blockchain has been relatively mature, and some progress has been made in the application field of jewelry + blockchain. Specific applications include: Based on proct traceability and jewelry and diamond trading and supply, Domenech's Maobei model, diamond + blockchain + new retail, which is the proct that I know should have practical application scenarios for diamond + blockchain;

7. Say strong, in the game book can only be regarded as entry-level graphics card, say weak, basically better than all the office books carrying graphics cards, such as mx250 / 150 and so on.

8. Chuangshi block contains a hidden information, and the input of coinbase transaction contains such a sentence as "the times 03 / Jan / 2009 merchant on brink of second low for banks."
this sentence is the title of the front page article of the times on that day. Quoting this sentence is an explanation of the generation time of the block, It can also be seen as a half joke to remind people of the importance of an independent monetary system, and to tell people that with the development of bitcoin, an unprecedented global monetary revolution will take place. The message was written into the genesis block by the founder of bitcoin, Nakamoto Tsung.

9. Shanzhai coin is not recommended
the price is just too high. It's because someone is cutting leeks behind their back
just like us dollar, how about Thai baht
Japanese yen, what about the Dong
it is suggested to start with bitcoin, lightcoin and Ethereum
- Bibo gold
