Each individual developer can create smart contracts supported by the Ethereum Blockchain and release their token. Previously, the applicability of coins handed over entirely to the developer of the coins.
It is experimental often involves a number of problems such as the freezing of funds of investors, an unexpected network operation or hacking of the contract. Ethereum protocol recently set up to correct the mistakes of the previous version. Maybe one of this option will replace the ERC20 at the end of the year so as to make the work with the Blockchain more reliable and easy for users.
ERC223 Will Fix the error ERC20
Standard ERC223 force ERC20 behaves the same way when the contract transferred to ETH. If an error occurs during the transfer function, or when the contract is smart does not support digital currency, the transaction eventually was canceled. For this purpose, two new functions launched:
Transfer function to replace the previous transfer and transferFrom.The TokenFallBack function determines the type of coin that is sent for the purpose of the contract.
ERC721: CryptoKitties
Thanks to the standard ERC721 each token becomes unique. Working with Layer 2 scaling function (State channels, sharding, and Plasma) we can get the primary means to put every important asset on a hybrid or public Blockchain with 100% security and eternity. Online game developer "Ethereum killer" behind the famous CryptoKitties was one of the first developers to adopt this standard. This standard is based on the use of unique attributes such as age, color, and breed. Some combination of attributes can be quite rare, thus making the cat dearly in the game.
ERC827: New ERC20
ERC827 is the latest version of the Protocol of the Ethereum. Unlike its predecessor, this standard has the ability to transfer data and transaction costs. This functionality makes it possible to move data around the world in a matter of seconds. This also allows the verification of the transaction by the third party. The reliability and security of Blockchain unchanged.italicitalic
