内容摘要
这一部关于区块链开发及运维的电子书。
为什么会写区块链电子书？因为2018年是区块链年。
这本电子书是否会出版（纸质图书）？ 不会，因为互联网技术更迭太快，纸质书籍的内容无法实时更新，一本书动辄百元，很快就成为垃圾，你会发现目前市面的上区块链书籍至少是一年前写的，内容已经过时，很多例子无法正确运行。所以我不会出版，电子书的内容会追逐技术发展，及时跟进软件版本的升级，做到内容最新，至少是主流。
这本电子书与其他区块链书籍有什么不同？市面上大部分区块链书籍都是用2/3去讲区块链原理，只要不到 1/3 的干货，干货不够理论来凑，通篇将理论或是大谈特谈区块链行业，这些内容更多是头脑风暴，展望区块链，均无法落地实施。本书与那些书籍完全不同，不讲理论和原理，面向应用落地，注重例子，均是干货。
电子书更新频率？每天都会有新内容加入，更新频率最迟不会超过一周，更新内容请关注 https://github.com/netkiller/netkiller.github.io/commits/master
本文采用碎片化写作，原文会不定期更新，请尽量阅读原文。

==============================
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。

测试步骤
peer chaincode install -n token -v 1.0 -p chaincodedev/chaincode/token peer chaincode instantiate -C myc -n token -v 1.0 -c '{"Args":[""]}' peer chaincode invoke -C myc -n token -c '{"function":"initLedger","Args":["Token","Netkiller Coin","1000000"]}' peer chaincode invoke -C myc -n token -c '{"function":"transferToken","Args":["Token","coinbase","netkiller","100"]}' peer chaincode invoke -C myc -n token -c '{"function":"balanceToken","Args":["Token","netkiller"]}' 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"]}'
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。

延伸阅读《使用代币替代传统积分系统》
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。
