由 Linux 基金会发起创建的开源区块链分布式账本 —— Hyperledger Fabric，已经迎来了 1.1 版本。该项目着重于性能和可靠性，以及推动区块链和分布式账本技术的跨行业协作。Hyperledger Fabric 可用于全球供应链管理、金融交易、资产账和去中心化的社交网络等场景，但无意以此来构建一种加密货币。 新版本可以从现有的1.0.x安装中进行升级，并包含许多新功能以及性能，规模和用户体验改进。 一些主要的新特性包括： Node.js chaincode support- developers can now author chaincode using the most popular framework for the world’s most popular programming language Channel based event service – to enable clients to subscribe to block and block transaction events on a per-channel basis. Ability to package CouchDB indexes with chaincode, to improve performance Ability to generate certificate revocation lists (CRLs) Ability to dynamically update client identities and affiliations Node.js SDK connection profiles to simplify connections to Fabric nodes Mutual Transport Layer Security (TLS) between Fabric nodes, and between clients and nodes Ability to encrypt ledger data for confidentiality using the chaincode encryption library Attribute-based Access Control in chaincode Chaincode APIs to retrieve client identity for access control decisions Performance improvements for transaction throughput and response time 完整内容参见这篇博客。 Hyperledger Fabric 1.1 发布，基于区块链的分布式账本下载地址
