20.4. 链码案例

20.4.1. 模仿以太坊 ERC20 规范的 Hyperledger Fabric 实现 Token 通证

借用以太坊思维，将以太坊代币合约搬到 hyperledger 上，一样可以实现代币的功能，这个代币除了不能上交易所，基本满足我们替代积分系统的需求，下面是我写了这样一个合约，在超级账本上实现类似以太坊的代币转账功能。

合约实现代币转账，额度查询，增发代币，冻结账号，锁仓等等服务器，功能与 ERC20 Token 相仿。

合约实例化所有代币打入了 coinbase 账号，分发代币需要使用转账功能从 coinbase 想普通账号转账

普通账号消费可以在将代币转到 coinbase 账号中，这样就完成了代币流通，形成一个闭环。

这个合约用户可以创建多套代币，Args":["Token" 的第一参数 Token就是代币名称

		
peer chaincode invoke -C myc -n token -c '{"function":"initLedger","Args":["Apple","水果币","1000000"]}'
peer chaincode invoke -C myc -n token -c '{"function":"initLedger","Args":["Token","蔬菜币","1000000"]}'
peer chaincode invoke -C myc -n token -c '{"function":"initLedger","Args":["Oil","粮油币","1000000"]}'

这个方案仍有不足之处，作者还不清楚如果用户上线是多少，达到临界值后，Hyperledger Fabric 无法在提供服务。

可能 chaincode_example02 做法更靠谱，就是不用 map 保存数据，将每个用户存储在 State 数据上。这里需要创建多套代币，所以使用了一个key 来存储所有账号。如果像 chaincode_example02 那样就需要部署多个 chaincode 在 channel 中。管理起来比较复杂。

peer chaincode invoke -C myc -n token -c '{"function":"transferToken","Args":["Token","netkiller","jerry","100"]}'

peer chaincode query -C myc -n token -c '{"function":"balanceToken","Args":["Token","netkiller"]}'

测试不存在账号转账

		
peer chaincode invoke -C myc -n token -c '{"function":"transferToken","Args":["Token","neo","netkiller","100"]}'

以太坊和超级账本各有优势，虽然超级账本的Token功能无法和以太坊相比，但是使用超级账本实现的Token交易不用矿工费。同事超级账本还有一个优势，就是可以在合约中调用另一个合约，这样一来可以做出很多复杂的需求

例如我们在订票的合约中，就可以直接从Token合约中直接扣款。

20.4.2. 万能的通用合约

我们一般会在合约中定义结构体，然后序列化后存入 state 数据库中。一旦数据结构变化，就需要升级 chaincode。

下面我们只实现了 create, find, update, delete 四个方法，没有数据结构，用户自行提交 json 格式或者其他序列化后的字符串数据。
