英国:保护区块链网络隐私的同时进行数据监管

英国中央银行英格兰银行(BoE)正在开发一种概念验证(PoC),希望借此了解能否在保证一个基于分布式账本的网络的隐私性的同时对数据进行监管。

英格兰银行于本周三发布了这份论文,阐述了该行与区块链基础设施协议开发创企Chain进行合作探索的这个项目的具体内容。

就在这篇论文发表几天前,英格兰银行发布了一项计划,将DLT解决方案作为下一代实时总结算系统的基础。

尽管承认理想的方案是“理论上可能的”,但英格兰银行表示,旨在保护网络共享数据隐私的加密解决方案技术仍处于非常初级的阶段。

该行总结称,这种数据模式的可行性仍需进一步探讨,尤其是在扩展性、交易处理速度以及围绕所使用加密技术安全性的风险方面。

The Bank of England, the U.K.'s central banking authority, is developing a proof-of-concept (PoC) examining how to maintain privacy over a distributed ledger-based network while still allowing a regulatory overview of the data.

Partnering for the project with Chain, a blockchain startup that develops infrastructure protocols, the Bank of England released a paper on Wednesday setting out how it is exploring how to maintain a high level of data privacy among participants over a distributed network, while at the same time facilitating transactions of different financial assets.

The ideal scenario, as pictured by the central bank, would be to design "a distributed ledger system in such a way that transactions remain private whilst keeping all data shared across the network, and at the same time maintaining a regulatory view of all transactions."

The PoC - which is aimed to build academic understanding, not as a practical solution - offers a window into the thinking of the U.K.'s central bank in advancing distributed ledger technology (DLT) development for existing business functions, while avoiding complete concealment of transactions from the authorities.

The paper comes just several days after the Bank of England released a plan to push a DLT solution as the basis for the next generation of its real-time gross settlement system, and for which the bank is currently testing a proof-of-concept.

That said, the primary hurdle, according to the central bank, is scalability, which is one of the top trade-offs as the institution considers its move towards the DLT system.

While arguing that the ideal scenario is "theoretically possible," the Bank of England stressed that the technology is still at a very nascent stage.

"The trade-offs would still need to be further explored, especially with respect to scalability, speed of transaction processing and risks around the security of the cryptographic techniques employed," the bank concluded.
