微软携手Tierion开发永久性身份数据区块链

据悉,科技巨头微软近日就如何维护公共区块链上敏感信息安全的问题与Tierion建立了合作伙伴关系。

来自微软云计算Azure身份数据团队的丹尼尔·巴切纳将领导一个名为“分散式身份数据倡议”的项目,这意味着微软将与Tierion公司及其开发人员展开广泛合作。微软和Tierion的开发团队都在寻求建立一个基于区块链的平台,通过这个平台,人们可以在一个永久性的、透明的生态系统中签署数据、声明和协议。

商业化

微软的最终目的是希望将一个安全的区块链平台商业化,使得广大用户可以通过它来保护不可改变的分类帐户中的数据。

微软正在积极检测区块链网络的一个关键属性——不可否认性。通过在不变的生态系统中嵌入特定的时间戳,让使用平台的个人或组织能够将某些数据集同特定的时间戳相互关联。

通过使用Tierion开发、引用的加密证明和底层基础设施,微软希望推出一个适用于处理各行业(如金融和医疗保健)复杂操作的系统。

不可否认性

微软 Azure 身份数据团队表示:

“不可否认性对于受监管行业,例如金融服务,医疗保健和保险,十分重要。 这些组织需要证明自己没有串通倒填日期或修改数据。Tierion通过将数据连接到区块链上,生成一个时间戳证明,映证数据的完整性和存在性。任何拥有此证明的人都可以独立地查验数据,不必依赖于权威的授权机构。”

微软:比特币太慢了

比特币并不是最灵活或最高效的区块链网络。类似于Ethereum的其他协议能够更加快捷地处理更多交易和结算。然而,正如Ethereum最近执行的一系列硬分叉所显示的那样,专注于灵活性和功能性的区块链网络通常无法保障安全性。

微软看上去有意选择那些打算优先考虑功能性和灵活性而非重点关注安全措施的区块链网络路径。微软认为比特币区块链速度太慢,效率太低,因此无法解决大量行业层面的协议。

微软Azure身份数据团队补充道:

“公共区块链,如比特币,非常安全,但是太慢。 比特币网络当前每秒约能完成四个交易。Tierion通过将数百万个数据点加密链接到单个交易以解决此类可扩展性问题。我们正在与Tierion合作,利用其开发的开源Chainpoint协议,将区块链作为可靠的锚点。”

在过去,开源软件,如Ethereum,尽管有世界各地经验丰富的开发人员和密码专家提供技术支持,但在处理安全问题和内部漏洞方面还是遇到了麻烦。微软和Tierion是否能够解决这些安全问题,将会是一件非常值得关注的事情。

 

 

Tech giant Microsoft has established a partnership with Blockchain identity startup Tierion to secure sensitive pieces of information on a public Blockchain.

Daniel Buchner from the Microsoft Azure Identity team will be leading a project called decentralized identity initiative which features extensive collaboration with Tierion and its developers. Cooperatively, the Microsoft and Tierion development teams are looking to build a Blockchain-based platform wherein anyone can sign data, claims and agreements in an immutable and transparent ecosystem.

Commercialization

Ultimately, Microsoft hopes to commercialize a secure Blockchain platform which can be utilized by a wide range of users to secure data in an unalterable ledger.

One key attribute of the Blockchain network that Microsoft is actively examining is non-repudiation. By embedding specific timestamps within an immutable ecosystem, individuals or organizations using the Blockchain platform will be able to relate certain data sets to specific timestamps.

Through the usage of cryptographic proofs and the underlying infrastructure developed and introduced by Tierion, Microsoft hopes to launch a system applicable to complex operations handled in various industries such as finance and healthcare.

Non-repudiation

The Microsoft Azure Identity team stated:

“Non-repudiation is important to regulated industries such as financial services, healthcare and insurance. These organizations need to prove there hasn’t been collusion to backdate or modify data. Tierion links data to the Blockchain and generates a timestamp proof of the data’s integrity and existence. Anyone with this proof can independently verify the data without relying on a trusted authority.”

Bitcoin is too slow says Microsoft

Bitcoin is not the most flexible or efficient Blockchain network. Alternative protocols like Ethereum are capable of processing more transactions or settlements at a faster rate. However, Blockchain networks that focus on flexibility and functionality can often compromise security, as seen in the recent series of hard forks executed by Ethereum.

Microsoft seems to be choosing the path of those Blockchain networks that intend to prioritize functionality and flexibility instead of setting the focus on security measures. Microsoft believes the Bitcoin Blockchain is too slow and inefficient to settle a large number of agreements at an industry level.

The Microsoft Azure Identity team added:

“Public Blockchains such as Bitcoin are exceptionally secure but slow. The current throughput of the Bitcoin network is about four transactions per second. Tierion solves this scalability problem by cryptographically linking millions of data points to a single transaction. We’re working with Tierion on a service that leverages the open source Chainpoint protocol their team developed for using the Blockchain as a trust anchor.”

In the past, open-source software like Ethereum had trouble dealing with security issues and internal bugs, despite technical contributions being submitted by experienced developers and cryptographers across the world. It will be interesting to see if Microsoft and Tierion will be able to deal with such issues surrounding security in the future.
