Fab公链要解决的问题
区块链技术是下一代互联网–价值互联网的基础，比特币及以太坊等区块链平台的成功运行，为区块链应用展示了良好的前景。
然而，由于受通讯、节点性能及共识机制等因素的制约，目前的公有区块链系统都面临交易处理能力严重不足的瓶颈问题，如比特币及以太坊每秒钟处理交易量都不超过15笔。
这是区块链迈向实用面临的巨大障碍，现实经济活动中，许多应用场景下的交易量都超过这一规模，如交易所、物联网平台、电商平台、供应链、医疗等，单个平台的实际交易量往往每秒钟几十笔、几百笔，甚至数千笔，而公共区块链是同时面向众多应用场景的，实际要求的处理能力要高得多。
解决这一问题迫在眉睫。
加拿大发企业系统公司区块链研发团队，历时五年探索，推出了具有良好扩展性能的全新区块链系统架构完善设计方案–快捷公共区块链（发链）系统(Fast Access Blockchain network–FAB)，致力于有效突破区块链技术障碍，为构造满足实际商业应用需求的区块链系统铺平了道路。
发链(FAB)是由经过一体化设计的三大组成——基础区块链、辅助区块链及开放存储架构组成，相互配合，构建了具有统一协议基础、功能相互协调、具有全程合法性及有效性验证、真正去中心化的、安全可靠的高性能区块链完整架构。
Fab公链设计原则
1. 构造信任–这是区块链的核心使命，系统设计的目的就是为应用构建一个可信任的系统。
2. 去中心化–是区块链的核心特征，是构造信任的根本手段。
3. 开放架构 |
