Erc20 Ethereum

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

5. What does trc20 mean? As we all know, there are many professional terms in the blockchain instry, especially some words related to technology, which are relatively obscure for many investors, but some common words we need to understand, such as erc-20 and trc-20 mentioned in this paper. What does it mean to mention these two words
trc20? As we all know, there are many professional terms in the blockchain instry, especially some words related to technology, which are relatively obscure for many investors, but some common words we need to understand, such as erc-20 and trc-20 mentioned in this paper. When we mention these two words, we have to mention usdt, and about usdt, As we all know, it is one of the entry currencies, a stable currency issued by tether company based on the 1:1 US dollar peg. So what does trc20 really mean? What does trc20 mean? And what's the difference between trc20 and erc20< br />


What does trc20 mean
rc20usdt is a stable currency jointly issued by wave field Tron and Teda Company tether. Compared with the old stable currency (omni usdt, erc20-usdt, etc.), trc20-usdt has greatly optimized the transfer fee and transaction confirmation speed

in terms of fees, trc20-usdt can realize free transfer. According to the withdrawal fees of mainstream exchanges, usdt based on Omni protocol has the highest withdrawal fee, ranging from US $4 to US $10, erc-20 from US $1 to US $5, and trc20-usdt has zero withdrawal fee, which means that users can enjoy the withdrawal service of exchange free of fees

in terms of transaction confirmation speed, usdt based on wave field network gives full play to the performance advantages of the third generation public chain. Wave field network's TPS can reach thousands of levels, and can realize transaction second level confirmation, which is significantly better than Omni (transfer confirmation takes 10 minutes to several days) and erc20 (minutes to several hours). The extremely fast transfer speed can meet the various needs of stable currency users, and avoid the damage to the interests of investors caused by network congestion

what is the difference between trc20 and erc20
1. Trc20 features

1

Yes! There is no service charge for transferring usdt in wave market, but there will be service charge for withdrawing trc-usdt in the exchange (charged by the exchange). Address example: (trc-20 contract)

2. It is still under test

most exchanges support the recharge of trc-usdt, but because trc-usdt is still under test, the recharge of the exchange is closed< Second, erc20 features

1. The type of service charge paid is eth

erc-usdt is the same as the token on other Ethereum, which is stored in Ethereum address, so the type of service charge to be paid is eth every time the transfer is made. Address example: (erc-20 contract)

2. Most exchanges support full withdrawal, and the withdrawal limit is low

basically, the mainstream exchanges support erc-usdt withdrawal, and they can choose to mention BTC address or eth address when withdrawing money. Moreover, taking fire coin as an example, the minimum withdrawal limit of erc-usdt (2 usdt) is currently less than omni usdt (200 usdt)< Different from omni usdt, erc-usdt can support smart contracts. In mainstream Ethereum browsers, you can query erc-20 usdt transactions. Interested users can go to tokenview's Ethereum browser to query erc-usdt transaction details

What does trc20 mean? Through the above introction, I believe you have some understanding of what trc20 means. As we all know, the advantages of trc20 can make investors feel good about investing in this kind of stable currency. With the halving of bitcoin, investors are uncertain about bitcoin, which aggravates investors' choice of stable currency, Therefore, some people in the currency circle think that the rise of trc20 as a global stable currency is the inevitable result of market choice

6. 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

7.

Rc20 token standard (erc20 token standard) is a standard used to create token through Ethereum. According to the erc20 specification, a smart contract can be written to create a "interchangeable token". It is not mandatory, but following this standard, the token created can interact with many exchanges, wallets, etc. it has now been widely accepted by the instry

erc20 token standard was first proposed by Ethereum developer Fabian vogelsteller in the open source community. Later, Ethereum founder vitalik (known as "V God") wrote the first version of the document, which was called "standardized contract API" at that time_ Contract_ APIs

following erc20 token standard, smart contracts can be written. The token methods it needs to implement include: optional name, symbol, decimals, balance of, transfer, transfer from, approve, and allowance. The event responses it needs to implement include transfer, approve

in addition to erc20, Ethereum also focuses on erc721. Different from erc20, erc721 is a non fungible token standard (NFT)

The general syndromes of

erc20 are interchangeable and homogeneous, while the general syndromes of erc721 are not interchangeable and heterogeneous; Erc20 can be subdivided infinitely, while erc721 can not be subdivided because its minimum unit is 1

in June 2018, erc721 was officially accepted by Ethereum community and became the final standard. The popular cryptokitties followed the erc721 standard
