21、最广泛的(目前）的区块链，各大bitcoins系列的虚拟数字货币均基于公有区块链，世界上有且仅有一条该币种对应的区块链。联合（行业）区块链（ConsortiumBlockChains)行业区块链：由某个群体内部指定多个预选的节点为记账人，每个块的生成由所有的预选节点共同决定（预选节点参与共识过程），其他接入节点可以参与交易，但不过问记账过程(本质上还是托管记账，只是变成分布式记账，预选节点的多少，如何决定每个块的记账者成为该区块链的主要风险点），其他任何人可以通过该区块链开放的API进行限定查询。私有区块链（privateBlockChains)私有区块链：仅仅使用区块链的总账技术进行记账，可

22、以是一个公司，也可以是个人，独享该区块链的写入权限，本链与其他的分布式存储方案没有太大区别。区块链的特征去中心化由于使用分布式核算和存储，不存在中心化的硬件或管理机构，任意节点的权利和义务都是均等的，系统中的数据块由整个系统中具有维护功能的节点来共同维护。开放性系统是开放的，除了交易各方的私有信息被加密外，区块链的数据对所有人公开，任何人都可以通过公开的接口查询区块链数据和开发相关应用，因此整个系统信息高度透明。自治性区块链采用基于协商一致的规范和协议（比如一套公开透明的算法）使得整个系统中的所有节点能够在去信任的环境自由安全的交换数据，使得对“人”的信任改成了对机器的信任，任何人为的干预不起

23、作用。信息不可篡改一旦信息经过验证并添加至区块链，就会永久的存储起来，除非能够同时控制住系统中超过51%的节点，否则单个节点上对数据库的修改是无效的，因此区块链的数据稳定性和可靠性极高。匿名性由于节点之间的交换遵循固定的算法，其数据交互是无需信任的（区块链中的程序规则会自行判断活动是否有效），因此交易对手无须通过公开身份的方式让对方自己产生信任，对信用的累积非常有帮助。区块链概念的应用区块链概念在艺术行业Ascribe让艺术家们可以在使用区块链技术来声明所有权，发行可编号，限量版的作品，可以针对任何类型艺术品的数字形式。它甚至还包括了一个交易市场，艺术家们可以通过他们的网站进行买卖，而无需任何

24、中介服务。区块链概念在法律行业BitProof是目前近些年来涌现的众多文档时间戳应用中最为先进的，将会让传统的公证方式成为过去。区块链概念在开发行业布比区块链是国内领先的区块链技术服务商，自成立以来一直专注于区块链技术与产品的研发与创新，拥有多项核心技术，并在多个方面取得了实质性的创新，形成多项核心技术成果，例如：可数学证明的分布式共识技术、快速的大规模账本存取技术、支持业务形态扩展的多链总账技术、异构区块链间的互联技术等。开发了自有的区块链基础服务平台，已在股权、供应链、积分、信用等领域开展应用。布比一直致力于以去（多）中心信任为核心，构建开放式价值流通网络，让数字资产自由流动起来。区块链概

25、念在金融行业越来越多的初创公司选择保留更长时间处于私人公司阶段（暂时不进入公开发行阶段），这意味着IPO之前的交易变得再次令人关注，因为投资者希望能够获得一些流动性，也可以减少早期阶段管理层的压力。通常私营公司在处理其股份交易时，需要经过大量的非正式系统，需要大量手工作业、基于纸张的工作，需要通过人工处理纸质股票凭证、期权发放和可换票据，需要律师手动验证电子表格等等，而这可能会造成很多的人为错误。许多企业正在寻求管理股份的有效解决方案，而Linq则在这个领域提供了一个全新的选择。Linq端到端的服务覆盖私营企业证券的发行、交易、登记管理。区块链可以移除私募股权市场对纸笔或者基于电子表格的记录保

26、存的需求，为用户提供一种不可篡改、永久保存的记录，兼具透明度和可审计性。这是这项技术拥有的最大优势。这种架构也允许用户迅速完成转换所有权，进一步降低了对手方违约、或遭第三方操纵的风险。区块链能帮助证券业达成长久以来梦寐以求的“即时交割”目标。?当大众对区块链技术还只是假设多过实际应用的时候，纳斯达克已经成为了行业领先者，并开启了一个新进程，可能会彻底改变资本市场基础设施系统的核心，尤其是对于交易结算和行政审批等过时的管理功能。不过，区块链用于证券交易存在交易结算延时较大、吞吐量较小的问题。比特币公有区块链（基于工作量证明机制）目前每秒可完成7笔交易，联盟链可以实现每秒10001万笔交易，而私有链可以到每秒10万笔。不过，基于股份授权证明机制的Bitshare每秒也可以达到10万笔交易（非常接近于传统的交易所），即使在恶劣情况下仍然能完成数千笔每秒的交易。相信随着技术进一步发展，区块链交易吞吐量能适应现实世界金融交易的需求。
