区块链的发展历史

1982年年
拜占庭将军问题
David Chaum提出密码学网路支付系统:David Chaum提出注重隐私安全的密码学网路支付系统,具有不可追踪的特性,成为之后比特币区块链在隐私安全面的雏形。
1985年
椭圆曲线密码学:Neal Koblitz和Victor Miller分别提出椭圆曲线密码学(Elliptic Curve Cryptography,ECC),首次将椭圆曲线用于密码学,建立公开金钥加密的演算法。 ECC好处在于可用较短的金钥,达到相同的安全强度。
1990年年
David Chaum基于先前理论打造出不可追踪的密码学网路支付系统,就是后来的eCash,不过eCash并非去中心化系统。
Leslie Lamport提出具高容错的一致性演算法Paxos。
1991年
使用时间戳确保数位文件安全:Stuart Haber与W. Scott Stornetta提出用时间戳确保数位文件安全的协议,此概念之后被比特币区块链系统所采用。
1992年年
Scott Vanstone等人提出椭圆曲线数位签章演算法(Elliptic Curve Digital Signature Algorithm,ECDSA)
1997年年
Adam Back发明Hashcash技术:Adam Back发明Hashcash(杂凑现金),为一种工作量证明演算法,此演算法仰赖成本函数的不可逆特性,达到容易被验证,但很难被破解的特性,最早被应用于阻挡垃圾邮件.Hashcash之后成为比特币区块链所采用的关键技术之一。
1998年年
Wei Dai发表匿名的分散式电子现金系统B-money:Wei Dai发表匿名的分散式电子现金系统B-money,引入工作量证明机制,强调点对交易和不可窜改特性。未采用Adam Back提出的Hashcash演算法.Wei Dai的许多设计之后被比特币区块链所采用。
Nick Szabo发表Bit Gold:Nick Szabo发表去过中心化的数位货币系统Bit Gold,参与者可贡献运算能力来解出加密谜题。
2005年
可重复使用的工作量证明机制(RPOW):Hal Finney提出可重复使用的工作量证明机制(可重复使用的工作证明,RPOW),结合B-money与Adam Back提出的Hashcash演算法来创造密码学货币。
2008年
Blockchain 1.0:加密货币
数位货币与支付系统去中心化,比特币:Satoshi Nakamoto(中本聪)发表一篇关于比特币的论文,描述一个点对点电子现金系统,能在不具信任的基础上上,建立一套去中心化的电子交易体系。
2012年
Blockchain2.0:智慧资产,智慧契约
市场去中心化,可作货币以外的数位资产转移,如股票,债券。如彩色便利基于比特币区块链的开源协议,可在比特币区块链上发行多项资产
2014年
Blockchain 3.0:更复杂的智慧合约
更复杂的智慧合约,将区块链用于政府,医疗,科学,文化与艺术等领域。
2016年
Blockchain 3.5:金融领域应用、资料层
Blockchain3.5:强调代币(货币桥)应用、分散式帐本、资料层区块链,及结合人工智慧等金融应用
区块链不是一促而就,也不仅仅只是一个名词,他从本质上讲,区块链技术,是一种交易记录的存储技术。
它促使我们,重新思考如何去创建交易、存储数据和交换资产,它是一场巨大变革的起点。

我今年看到很多关于区块链应用的文章,国内的,很多方面都有,就比如前久看见的区块链手机,但是现在就听见,真的东西是真的没有看到过,我个人是很喜欢区块链这个东西的,他带来的便捷,去中心化的自由方式我很喜欢,但是感觉现在一地都是些数字货币,其他的能给我提供好的服务的真的没有发现!
