Ethereum Genesis block parameters

Publish: 2021-05-22 19:09:31
1. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of tens of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform

warm tips: the above explanations are for reference only, without any suggestions. There are risks in entering the market, so investment should be cautious. Before making any investment, you should make sure that you fully understand the nature of the investment and the risks involved in the proct. After a detailed understanding and careful evaluation of the proct, you can judge whether to participate in the transaction

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.

  1. about the variability of blockchain

  2. eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts

  3. etc, blockchain records and contracts can't be modified, that is, they can't be tampered with

  4. here are the advantages and disadvantages of the two methods

    The advantage of
  5. variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes

  6. non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework

  7. differences in development

  8. eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it

  9. etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation

  10. in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal

  11. about compatibility

  12. at present, the two kinds of blockchains are compatible with each other. Contracts or applications written by eth can be applied on etc, and vice versa

  13. eth, focusing on ewasm, is committed to providing a platform for more and more developers, while the issue of contract security is secondary, such as viper

  14. etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers

  15. it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct

  16. about the transaction speed

  17. eth, the average is 25 seconds, which will be shortened after upgrading

  18. etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols

  19. about the block capacity

  20. eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit

  21. ETC­, At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth

  22. about community

  23. eth, mainly discuss on reddit

  24. etc, mainly discuss on slack

  25. about monetary policy

  26. eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle

  27. etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation

    As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25%

    In etc, China accounts for 50%, South Korea 25% and the United States 10%

    About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators

  28. etc owns etc trading trust, which allows investors to own etc instead of the asset itself

4. 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!
5. To create a Genesis configuration file:
first, you need to create a "Genesis" JSON configuration file, which describes some parameters of the genesis block. The following is the content of the file:
{
& quot; coinbase": & quot;& quot;,< br />" config": {< br />" homesteadBlock": 5
},
" difficulty": & quot; 0x20000",< br />" extraData": & quot; 0x",< br />" gasLimit": & quot; 0x2FEFD8",< br />" mixhash": & quot;& quot;,< br />" nonce": & quot; 0x0",< br />" parentHash": & quot; 000000000000000000000000",< br />" timestamp": & quot; 0x00",< br />" alloc": {< br />"& quot;:< br />{
" balance":& quot;& quot;
}
}
} 1234567891011213141516171819

the above code into a text file and name it genesis.json

Genesis!:
in order not to conflict with the data of the main chain, it is recommended to establish your own private chain data folder. On my computer, I built an ethdbspace as the Ethereum experimental work area on disk e, and created a privchain folder as the data storage folder of my first private chain
here, in order to facilitate management, I put genesis.json under the ethdbspace folder
open the windows command line

type the following command
geth -- dataDir & quot; E:\ EthDBSpace\ PrivChain" init " E:\ EthDBSpace\ genesis.json" 1

– the dataDir option is used to specify the data directory of our private chain. On my computer, it's E: &; EthDBSpace\ Privchain
init is the genesis command, followed by our Genesis configuration file path
after clicking enter, the execution result is as follows

at this time, genesis is complete
create an account:
in order to do experiments on the private chain, we also need to create our own account on the private chain
windows command line, type
geth -- dataDir & quot; E:\ EthDBSpace\ PrivChain" Console1

we have successfully created the world, so when we enter the client for the second time, we do not need to specify the genesis.json file path again, but directly – dataDir to indicate the private link data path
the console command is used to open the command line of geth
after clicking enter, the client will be initialized for a while. After the command prompt appears, it means that you have entered the geth console

type
personal. Newaccount (& #) in the geth command line; Your Password') 1

the personal.newaccount function is used to create an account, in which the parameter is the account password.
after clicking enter, the account creation address will be listed in green below the command, that is, the public key of the account.
we can check the account balance first, In the geth command line, type:
My = eth. Accounts [0]
eth. Getbalance (my) 12

My = eth. Accounts [0]. The purpose of this sentence is to assign the account address we just created to my variable. This can simplify the subsequent account address input. Among them, eth.accounts records the addresses of all accounts on this machine. Since we created an account for the first time, there is only one account on the computer at present. So here we use eth. Accounts [0] to extract the first account address. The eth.getbalance function is used to obtain the account balance, and the parameters are filled in the account address. The my variable here records the address of the first account

I hope my answer can help you
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
