区块链即服务平台BaaS白皮书
区块链即服务平台BaaS白皮书．,.．..．．．．序言2008 年末中本聪发布比特币白皮书所标志的区块链诞生，至本白皮书初版发布，已经过去了整整十年。
这十年间，区块链从鲜为人知到家喻户晓，从街谈巷议到饱受质疑，其过程不可谓不惊心动魄，跌宕起伏，像极了上世纪九十年代Tim Berners-Lee 发明了万维网的最初十年。
很多人喜欢将区块链网络类比于互联网，因为区块链构建的是一种价值网络。
当然二者其实是很不一样的，但无可非议的是，区块链会成为未来社会的一种基础设施，大量的应用将会构建在区块链网络之上。
区块链即服务（Blockchain as a Service, BaaS）平台便是为构建区块链的基础设施所做出的重要努力。
BaaS 平台旨在提供创建、管理和维护企业级区块链网络及应用的服务，能够帮助用户降低开发及使用成本。
通过BaaS 平台提供的简单易用、成熟可扩展、安全可靠、可视化运维等设计特色，区块链开发者能够满足快速部署、高安全可靠性的需要，为企业高效地开发出区块链应用。
本白皮书由浅及深地介绍了区块链即服务平台的技术细节与应用场景。
基本的模块设计从功能上可划分为资源管理层、区块链底层技术和平台管理层三个层次，其底层的关键技术包括可插拔的共识机制、高可用存储和多类型账本支持、多类型的交易模型、多语言支持的智能合约引擎以及安全隐私保护。
除了这些基本的区块链特性之外，BaaS 平台还会提供跨云部署、跨链交互、链上链下访问和分布式身份管理等高阶特性。
最后，本白皮书还分享了几个基于BaaS 平台落地的重要案例，为区块链应用的开发和创新提供多视角的思路。
该白皮书是可信区块链推进计划在区块链即服务平台领域的第一个白皮书，由于编写时间仓促，该白皮书存在一定的不足，欢迎业内各界人士沟通交流讨论。

苏宁区块链白皮书
苏宁区块链白皮书i•序一零售业是人类最古老的商业，苏宁控股董事长张近东提出“智慧零售”时，零售业的发展已经经历了三个阶段。
从实体门店，到电子商务，再到O2O融合的智慧零售，零售生态发生了翻天覆地的变化。
消费者的行为习惯也从追求性价比、品质化商品，发展到追求个性化定制商品。
消费者的行为习惯直接推动了零售商和制造商的商业模式变革，即从规模化、低成本到高质量、定制化的变革。
在这场影响全人类的变革中，“数据”扮演着最为核心的角色。
真实数据的产生，流转过程的可控，明确的数据利用规则，隐私数据的保护，则是变革的核心议题。
传统技术在这些方面存在很多弊端，也导致了目前社会上存在的各种问题。
比如用户隐私泄露，各种隐私数据被第三方收集、整理、贩卖；合同欺诈，合同执行困难；版权作品维权难、追责难等。
而最近几年兴起的区块链技术从一个全新的角度，融合使用点对点去中心化网络、共识机制、智能合约、加密体系等，给出了相关的解决方案。
苏宁联合了内部各相关的技术、业务、职能体系，对区块链在智慧零售生态中的使用方式，落地场景，解决方案进行了深入研究，编撰形成了《苏宁区块链白皮书（2018）》。
白皮书提炼了区块链的关键技术变革点，梳理了区块链技术的核心特征；总结了目前区块链落地应用的场景，着重给出了各场景下的具体解决方案；分享了苏宁区块链平台的发展技术路线和架构，期望能给业界提供有价值的参考。
在智慧零售生态中落地区块链应用过程中，我们也遇到很多困难，区块链技术落地到实际应用场景中存在各种问题，这驱使我们进行相关的创新和改进。
同时，我们也深刻认识到，区块链的最终目标将是“让世界更自律、更高效”。
苏宁将为这个伟大的目标贡献自己的力量，也期待更多有识之士加入到这场深刻的变革中来。
苏宁科技集团副总裁乔新亮•序二区块链作为当前计算机领域的最前沿的技术之一，得到了业界的广泛关注。
随着对“去中心化”思想理解的不断深入，人们对区块链技术的理解正逐渐从支持比特币的单纯技术平台向信息系统构建新的思维方式转变，各个领域都在将去中心化的思想和行业的痛点相结合，打造新的业务模式。

区块链自21世纪初期发展起来，是目前全世界认为最有潜力、最具想象力的一种技术革新。
在人类的发展史上共经历过三次工业革命，第一次以蒸汽机的发明为标志，让机器代替了手工劳动；第二次以电能的突破、应用和内燃机的发明为标志，直接推动人类进入电气化时代；第三次以电子计算机、核能、空间技术、生物工程的发明和应用为标志，不仅推动人类社会的巨大变革，更深刻地影响了人类的生活和思维方式。
每一次工业革命都带来生产力的巨大提升，而作为生产要素之一的生产关系，改变并没有那么巨大，依旧是自上而下、金字塔层级的中心化组织。
组织的业务越复杂，层级越多，效率提升就越困难。

2023-区块链白皮书2020年-1
区块链白皮书2020年区块链是一种新兴技术，被广泛应用于数字货币，智能合约和认证等领域。
为了推动区块链的发展和应用，区块链白皮书2020年应运而生。
该白皮书从多个角度探讨了区块链技术的进展和应用。
第一步，白皮书介绍了区块链技术的基本原理和优势。
区块链是一种去中心化的数字数据库，可以将交易记录以块的形式保存，形成不可篡改的链式结构。
区块链技术具有高度安全性和透明度，使得区块链可以应用于金融和医疗等领域，提高效率和降低成本。
第二步，白皮书探讨了区块链技术在数字货币和资产管理中的应用。
数字货币已经成为区块链技术最成功的应用之一。
由于区块链技术具有高度的安全性和可追溯性，数字货币可以有效避免传统货币交易中的一些问题。
此外，区块链技术也可以用于资产管理，它可以提供更安全的交易和记录方式，减少欺诈和误差。
第三步，白皮书探讨了区块链技术在智能合约和供应链管理中的应用。
智能合约可以帮助各方协商和执行合同，从而减少人为介入和误操作。
供应链管理也可以通过区块链技术实现更高效和安全的交易和记录方式。
例如，通过区块链技术，可以记录货物的来源，质量，运输和交付等信息，有效避免诸如假货和盗窃等问题。
第四步，白皮书探讨了区块链技术的发展趋势和前景。
虽然区块链技术已经取得了一定的进展，但是仍然存在一些挑战，如扩容问题，监管合规问题等。
然而，随着技术的不断发展和应用场景的不断增加，区块链技术的未来发展前景仍然十分广阔。
综上所述，区块链白皮书2020年是一份十分重要的技术文章，探讨了区块链技术的发展和应用。
该白皮书对于推动区块链技术的发展和应用有着重要的作用。
我们相信，通过不断的探索和创新，区块链技术的应用范围和影响力将会逐步扩大。
