三、对腾讯云区块链（TBaaS）开发平台的介绍。首先介绍了腾讯云区块链诞生的原 因，并对其设计原则进行了详细讲解， 然后说明了其能够为行业带来的不同服务能力， 最后对 其后台技术架构进行了相关介绍。 四、 基于腾讯云区块链 （TBaaS） 的应用场景及解决方案。 提出了包括在共享账本、 公证与 记录、 互助保障、 数字资产 、 防伪溯源、 物联网、 共享经济等应用场景能够解决的业务痛点， 并分 别枚举了相关案例进行阐述说明。 五、 对区块链未来应用的展望。 基于现有的区块链应用场景， 对区块链的多平台互通、 链外 信任机制， 以及其在未来能够带来的更大价值进行了开放式的展望和创想。腾讯云区块链团队2018年3月30日 前言 每一次产业变革的浪潮都带给世界全新的机遇与想象。 区块链技术的诞生，真正意义上为数字经济提供了全新的价值转移通道，其应用场景几 乎不可限量。工信部于2016年正式发布的中国区块链技术和应用发展白皮书，充分展 示了国家层面对区块链技术的重视程度。 然而，目前区块链底层技术不完全成熟、基础设施未全面完善的形势还没有获得根本性 转变，企业无法快速地投入生产力到基于区块链技术的各种业务场景中去，区块链技术面临 的普及性问题亟待解决，值此关键时间窗口，腾讯云区块链（TBaaS）破茧而生。 2015年3月，“互联网+”战略被写入政府工作报告成为国家级战略，腾讯坚持做互联网 连接器的定位，完全契合国家层面的指引方针。腾讯云区块链（TBaaS）同样延续了腾讯的 战略定位，以降低区块链技术的应用门槛、打造可信赖的企业间价值通道为使命。腾讯云区 块链（TBaaS）的推出，将使个人、企业级用户不仅能够便捷、高效、安全地享受到区块链 技术的价值，且对其主体业务不会造成任何形式的侵扰，充分体现了“区块链+”的战略定 位。 大鹏一日同风起，扶摇直上九万里。体量巨大的市场需求和前景可期的应用场景，将为 整个区块链生态的发展提供强大助力。腾讯云自始至终是值得信任的云服务平台，我们热忱 期待与行业为伍、与趋势为伴，为企业、个人客户提供更为优质的云服务，带来更为友好的 云体验，为云技术、区块链技术的繁荣发展做出应有的贡献。 腾讯云区块链（TBaaS）将是一个有能力为客户创造和提供商业价值的智能服务平台， 其以云计算平台为依托，利用区块链技术与各行业应用相互融合，推动自有产业转型升级， 为客户创造全新的产品、业务和商业模式。为了充分阐明和体现腾讯云区块链（TBaaS）能 够赋予全行业的商业能力，我们编写了本白皮书，主要包含如下内容： 一、阐述了区块链的起源与发展。首先对区块链的技术原理进行了讲解，提出了区块链 多方共识、弱中心化、信息不可篡改以及智能合约等特点，并介绍了区块链在社会关系、经 济效益等层面所带来的积极意义。 二、对区块链应用领域的介绍。通过援引“区块链+场景”的案例，详细阐述了区块链在 金融、供应链、公益慈善、公共服务、物联网、共享经济等相关领域的各类应用。三、对腾讯云区块链（TBaaS）开发平台的介绍。首先介绍了腾讯云区块链诞生的原 因，并对其设计原则进行了详细讲解，
