<title>Hyperledger Fabric</title>
<para>区块链技术发展至今，形成了公有链、联盟链和邦链三种种主流技术平台。</para>
<para>公有链：
面向大众，用户可以匿名参与，非常方便，账本数据也公开，加上强大的智能合约，因此公有链极大地促进了区块链概念和技术的普及，比如比特币、Ethereum平台等。</para>
<para>联盟链：
考虑到商业应用对安全、隐私、监管、审计、性能的需求，提高准入门槛，增加了安全、隐私、可监管审计等商业特性，是区块链技术在商业领域的应用探索。</para>
<para>邦链：暂时资料比较少。</para>
<para>概念</para>
<para>通道（ Channel ）：通道是构建在 Hyperledger Fabric
区块链网络上的私有区块链，实现了数据的隔离和保密。通道中的 Chaincode 和交易只有加入该通道的节点（ Peer
）可见。同一个节点可以加入多个通道，并为每个通道内容维护一个账本。每一个通道即为一条逻辑上的区块链。可以按照业务来划分通道，也可以按照行政职能和隐私策略来划分通道。</para>
<para>节点（ Peer ）： 维护账本的网络节点，通常区块链网络架构中存在多种角色，如 endorser 和 committer 。</para>
<para>排序服务或共识服务（ Order Services ） ：
提供排序服务或共识服务的网络节点，完成交易的排序和区块打包等工作，支持可插拔的共识组件，当前生产环境下使用 Kafka 进行交易排序。</para>
<para>分布式账本（ Distribute Ledger ） ：由网络中若干去中心化节点共同维护的数据账本。</para>
<para>组织（ Org ） ：联盟链中按照
访问和使用账本的网络节点，一个联盟（或者一个区块链网络）有多个组织（成员），一个组织内可以有多个节点（ Peer
），每个节点参与账本和世界状态维护。</para>
<para>智能合约（ Smart Contract ）
：根据特定条件自动执行的合约程序。智能合约是区块链的重要特征，是用户与区块链进行交互，利用区块链实现业务逻辑的重要途径。</para>
<para>链码（ Chaincode ）：链码是 Hyperledger Fabric 对智能合约的一种实现方式，是运行于
Hyperledger Fabric 网络之上一段应用程序代码，也是用户与 Hyperledger Fabric 交互的唯一途径。</para>
<para>链（ Chain ）：一个链即是一个由若干区块通过特定指向链接、摘要算法或加密算法锚定组成的数据集合。</para>
