区块链非金融应用
文件(一切皆文件)真实性验证
- 所有权证明
- 特定时间的存在证明(相当于报纸吧,可以证明那个时候发生的事)
- 完整性证明,防止被篡改过(商品防伪呀都类似吧)
上述都基于区块链的不可修改性。
案列一:Block Notary是一个ios app,通过使用TestNet3或者Bitcoin network,它可以帮助你创建(photo、files、any media)的存在证明。(存在证明)
案列二:Proof of Existence is a service which uses blockchain to SHA256 digest of the document in bitcoin blockchain.(通过对文献进行SHA256计算,生成对应的散列值,再存储到bitcoin的区块链中,即存在证明)
案列三:Ascribe is another company which does authorship certification using blockchain. It also offers transfer of ownership service with attribution to the original author.(所有权证明)
去中心化云存储
主要通过区块链,来解决云存储的安全、隐私、数据控制等问题。
案列:Storj是一个去中心化的基于区块链的点对点分布式云存储平台,允许用户在不依赖第三方机构的情况下传输和共享数据。(想想这个平台也不错,要是国内能开发一个,并流行起来也挺不错)
去中心化物联网平台
案列:IBM, in partnership with Samsung, has developed a platform ADEPT (Autonomous Decentralized Peer To Peer Telemetry) that uses elements of the bitcoin’s underlying design to build a distributed network of devices, or decentralized Internet of Things (IOT). ADEPT uses three protocols in the platform: BitTorrent (file sharing), Ethereum ( Smart Contracts) and TeleHash (Peer-To-Peer Messaging).
基于区块链的防伪解决方案(电子商务所需)
