关于 ERC827 代币标准
It retains the easy-to-use and heuristic nature of the ERC20 standard that we are all used to, but builds upon and improves it, like ERC223 attempted to improve ERC20. The “motivations” section explains that in the current ERC20 model, only value can be transferred. However, Ethereum users can transfer value and data thanks to ERC827. Also, with ERC827, tokens can be approved to be spent by other on-chain third parties.
作为 ERC20 的扩展，之前 ERC223（已基本放弃） 也是对 ERC20 的试图改良。在当前的 ERC20 模型中，只有价值才能被转移。然而通过 ERC827，以太坊用户不仅可以转移价值，还可以传输数据。此外，通过 ERC827，代币可以被第三方链承认。
Because it takes some of the more pressing shortcomings of the current ERC20 token standard and improves upon them while retaining the compatibility with ERC20, I think that ERC827 is going to be rather popular among new projects and upgrades to current/past projects. The fact that it is fully ERC20 compatible is what this new token standard really has going for it, in my opinion. Not only will users be able to utilize all the benefits of the new standard, but they will also be able to keep using the ERC20 token standard that they have become accustomed to. It’s a win-win.
ERC827 对 ERC20 是向下兼容的，意味着不仅新项目可以基于 ERC827 开发，老项目也可以升级到 ERC827 上来。
