Building Ethereum erc20 Wallet

1. Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum"). The concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform". It began to develop through ICO crowdfunding in 2014
Ethereum is not only a database, it also allows you to run programs in the trusted environment of the blockchain. Ethereum has built a virtual machine named EVM (Ethereum virtual machine) on the blockchain. EVM allows code to be verified and executed on the blockchain, providing guarantee for code to run in the same way on everyone's machine. These codes are included in the smart contract. In addition to tracking the account balance, Ethereum uses the same method to save the EVM status on the blockchain. All nodes process the smart contract to verify the integrity of the contract itself and its output.

2. I personally suggest and recommend VJC. After all, Ethereum has been around for some time, and many investors have already owned it. However, Yutong chain is different. It has just been launched on the stex. Exchange platform for less than a month, and other trading platforms have not yet been launched. This is enough to prove that there is still a lot of purchasing power and the price is not high. The current price is more than $1.

3. After giving birth to the baby, the body is more empty at the beginning. It is suggested to adjust after a while. Generally, it will be two or three months after returning to the previous state. The center of confinement is relatively better

4.

Many places in China are experimenting with the use of digital RMB, and the convenience of digital RMB is as follows:

First: Digital RMB can be used offline

although mobile payment is very common now, any third-party payment software needs to be connected to the Internet. Alipay and WeChat also monopolize the third party payment market, but once these two software are not connected, they will not be able to complete the payment. Although it's all right to go out with your mobile phone now, you don't need to bring your wallet and cash, but all this is based on the fact that your mobile phone has electricity and network

The consumption habit of

is unhealthy, so digital RMB is actually a more real and planned payment method, which is helpful for young people to develop good consumption habits. This can avoid over consumption and other bad habits

5. Imtoken doesn't have BTC wallet, it can only store erc20 token

6. No, I can't. let's switch to other ways

7. Before BTD was connected to the public chain, the wallet address was also the address of Ethereum

later, when BTD was connected to the public chain, it used its own wallet address
now we see that the
erc20 address in the binding address doesn't need to be taken care of, just bind the BTD's wallet address
