2.0生命周期 fabric java 链码安装
2.0生命周期 fabric java 链码安装
步骤 :
打包&安装
批准
提交
-
首先打包chaincode:这个步骤可以由一个组织来完成，也可以由每个组织来完成。
在你的peer中安装chaincode:每个使用chaincode来签署交易或者查询分类账的组织都需要完成这个步骤。批准您的组织的chaincode定义:每个使用chaincode的组织都需要完成这个步骤。在可以在通道上启动chaincode之前，chaincode定义需要得到足够数量的组织的批准，以满足通道的生命周期许可策略(默认情况下是大多数)。将chaincode定义提交给通道:一旦通道上所需的组织数量得到批准，提交事务就需要由一个组织提交。提交者首先从已经批准的组织的足够多的同行那里收集背书，然后提交事务以提交chaincode定义。 -
