matrix

/- A token is a representation of something in the blockchain. This something can be money, time, services, shares in a company, a virtual pet, anything. By representing things as tokens, we can allow smart contracts to interact with them, exchange them, create or destroy them. /– A token contract is simply an Ethereum smart contract. “Sending tokens” actually means “calling a method on a smart contract that someone wrote and deployed”. At the end of the day, a token contract is not much more a mapping of addresses to balances, plus some methods to add and subtract from those balances. /– It is these balances that represent the tokens themselves. Someone “has tokens” when their balance in the token contract is non-zero. That’s it! These balances could be considered money, experience points in a game, deeds of ownership, or voting rights, and each of these tokens would be stored in different token contracts. /– Note that there’s a big difference between having two voting rights and two deeds of ownership: each vote is equal to all others, but houses usually are not! This is called fungibility. Fungible goods are equivalent and interchangeable, like Ether, fiat currencies, and voting rights. Non-fungible goods are unique and distinct, like deeds of ownership, or collectibles.

/-令牌是区块链blockchain中某物的表示。这些东西可以是金钱,时间,服务,公司股份,虚拟宠物,任何东西。通过将事物表示为令牌,我们可以允许智能合约与它们交互、交换、创建或销毁它们。/-代币合约只是以太坊eth智能合约。”发送令牌“实际上意味着”调用某个人编写和部署的智能合约上的方法“。归根结底,代币合约不过是地址到余额的映射,再加上一些从这些余额中加减的方法。/-正是这些余额代表了代币本身。当代币合约中的余额为非零时,有人“拥有代币”。就这样!这些余额可以被视为金钱、游戏中的经验点、所有权契约或投票权,而这些代币中的每一个都将存储在不同的代币合同中。/-请注意,拥有两个投票权和两个所有权契约之间有很大的区别:每个投票权与所有其他投票权相等,但房屋通常不相等!这就是所谓的可替代性。可替代商品是等价的和可互换的,比如乙醚、法定货币和投票权。不可替代商品是独特的,就像所有权契约或收藏品一样。
