Does Ethereum need ABI for docking
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
Generally speaking, the steps of deploying smart contract are as follows:
- start an Ethereum node (such as geth or testrpc)
- use Solc to compile smart contracts=& gt; Get the binary code
- deploy the compiled contract to the network This step will consume Ethernet currency, and you need to use the default address or specified address of your node to sign the contract.)=& gt; Get the blockchain address and ABI of the contract (JSON representation of the contract interface, including variables, events and callable methods) The author confused ABI with contract interface here. ABI is the binary representation of the contract interface.)
- use the JavaScript API provided by web3.js to call the contract Depending on the type of call, it may consume Ethernet currency.)
Ruitai coin has not been launched on the third-party platform, but it is rumored that it will also be launched on the third-party platform.
blockchain is not only about issuing money, but also can be applied in many places. The biggest feature of blockchain is decentralization. General Internet procts are centralized, and blockchain can use decentralization to solve the trust problem between each node. Because in the blockchain, information is traceable and cannot be tampered with
now there are many blockchain landing projects. You can properly understand that it is not a simple coin issuing thing, nor a deceptive project.
The usdt on hotcoin can't be transferred to the imtoken wallet. Because imtoken does not support usdt
usdt is based on BTC block network, and can withdraw money normally, depending on whether the other platform supports receiving. It is invalid because the imtoken wallet is not connected to usdt
usdt can be transferred to bitpie. However, it is generally not recommended to keep usdt for a long time
imtoken wallet is an exclusive Ethereum wallet, which can only be used to store the token of Ethereum. The usdt TEDA currency is exchanged with the US dollar, 1 usdt = 1 US dollar
extended information:
for the usdt TEDA coin purchased on huoyuan.com, you need to transfer the currency of the legal currency account to the trading account, and then the button of withdrawing the currency will appear below the usdt. If there is no transfer, the button of withdrawing the currency will not appear. Then we can see if the wallet platform of imtoken can receive this coin, which can help us find the answer
after that, it is usual to transfer the usdt on the hotcoin network into the imtoken. If the imtoken does not support it, just find another wallet that can support the storage of usdt
advantages of fire coin network:
1. It is safe and reliable, easy to use, and the proct user experience is particularly friendly
2, support OTC legal tender transactions, support WeChat, Alipay and bank card transfer. p>
3. It is easy to apply for registration, with many currencies and large turnover, which is convenient to buy and sell at any time

one: there is something wrong with the line.... Check the line connector< The cat is broken.. Change a cat
3: operator server problem / this.. This.. It seems unlikely.
no traffic jam, about two hours more.
