1.
in order to create erc20 token, you need to write down the following contents
- token name
- token symbol
- token decimal
- number of tokens is in circulation
- Contract
- code verification source code
in addition to erc20, there are erc20, erc721, erc223, erc621, erc827, But for erc721, by the way, erc721 is a protocol mainly used for blockchain games. The blockchain games you often see are basically based on erc721
2. 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.

3. Enj token brief information
enj's total supply of tokens is 10000000000 enj (1 billion), which is an alternative erc-20 token on the Ethereum blockchain. It also supports alternative and irreplaceable erc-1155 smart contracts. The current price is: ￥ 0.3429 (2020-03-17)
the Enjin coin ICO was held from July 2017 to November 2017 and raised about $22 million in eth. About 80% of the total token was sold, and the remaining 20% was allocated to the founding team, companies and investors. Combined with other sales channels, the project raised about $35 million
enj cannot be g like bitcoin. When users create custom erc-1155 assets, enj will be destroyed
enj (2020-03-17) worth about 60 million RMB is traded every day. The cryptocurrency exchanges that accept enj include ratoken, coin security, upbit, bittrex and hitbtc. Trading pairs including BTC, ETH, usdt and fiat currencies, such as KRW and USD, are accepted in Korea and the United States
as erc-20 token, enj can be stored in any erc20 compatible Ethereum wallet, including myetherwallet, trust wallet, trezor and Archos hardware wallet. The team also developed Enjin smart wallet, which makes it easy to purchase digital goods with encryption. Following the release of the ecological win-win plan by okcoin and coin security, fire coin also launched the "fire coin cloud" output technology, and the exchange's "ecological war" started
on July 20, fire coin, a digital asset trading platform, announced that fire coin Group & quot; Fire coin cloud & quot; The business was officially launched, allowing users to build a digital asset exchange on the existing platform of fire coin.

Fire coin hopes to share with global partners the experience, ability and resources accumulated by fire coin in the field of digital asset exchange and even the whole blockchain ecology, and work together to promote the development of blockchain instry and achieve win-win results
previously, okex launched the "open and win-win plan of digital asset exchange", and coin an also released the "Alliance Plan of digital asset exchange", which are similar to fire coin cloud. They all use their own experience, ability and resources to help partners build a digital asset trading platform and seek ecological win-win.

4. At present, there are many digital currency wallets, some of which have good personal experience
light wallets are good for imtoken, geekwallet, kcash, Cobo, etc.
Hardware wallets are good for ledger, trezor, etc., which involve large amount of digital currency or hold for a long time. Generally, hardware wallets are recommended
big body introces these personal good light wallets

5. No, I can't. let's switch to other ways
6. Jasmy coin uses Ethereum's address to sign the transaction, and pays the service charge by eth. Its own function also meets the erc20 standard.
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 oferc20 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
