Libra发布2.0白皮书,推出单货币稳定币,并放弃向无许可系统过度_LibraNews_服务于区块链创新者

详情页1

北京时间4月16日晚间,沉寂一段时间的Libra再次出现在社区眼前。由Facebook打造的Libra发布了白皮书更新版——Libra 2.0(全文下载),其中对Libra的设计进行了多处重大更改。Libra Association开发者生态体系主管Michael Engle在Libra官网发文讲述Libra 2.0的发布背景。以下是全文内容:《Libra开发者:未来之路》(Libra developers:the path forward)

从第一天开始,天秤座(Libra)项目的目标就是建立一个简单的全球支付系统和金融基础设施,赋能数十亿人口。自2019年6月首次发布白皮书之后的几个月里,我们与监管机构,央行行长,官员和各利益相关方密切合作,努力塑造一种创新方法,利用区块链技术来支持一个受监管的,许可的支付系统(注:放弃了最初白皮书中过渡为一种无需许可系统)。这次更新的白皮书(Libra 2.0白皮书)概述了自2019年6月以来我们在天秤座支付系统设计方面所做的重大工作。

我们对最初采用方法进行了更改,其中许多方法与其他区块链项目采用的方法不同。我们的目标绝不是模仿其他系统,而是利用分布式治理和分布式技术的创新方法来创建一个开放且可信赖的系统。通过进行艰巨工作来提升传统金融系统,使其变得可编程,可互操作和可升级,我们希望允许其他人利用我们的努力来构建不仅可以服务于所有人的创新型金融应用,而且还可以确保其安全合规。我们感谢与世界各地决策者的讨论,他们帮助我们了解了关键问题,以便我们将可行的改进措施整合到Libra支付系统的设计和分阶段推出计划中。

我们将Libra 2.0中给开发人员带来最直接影响的更改概括如下:

  • 将区块链技术与公认的监管框架相结合。
  • 除了锚定多货币的稳定币之外,还提供单币种稳定币。
  • 分阶段部署天秤座(Libra)网络。

1 将区块链技术与公认的监管框架相结合

我们的目标是建立一个开放的平台并与协议级别的控件实现互操作,以帮助开发人员满足高标准的合规性。我们将专注于最佳的方法,将区块链技术与公认的监管框架相结合。

更新后的Libra白皮书(Libra 2.0)概述了网络参与者的类别,包括虚拟资产服务提供商(VASP)和无托管钱包(Unhosted Wallets)。我们相信大多数人将通过VASP与Libra付款系统进行交互,例如托管钱包和交易所。我们还认为,重要的是,通过启用具有协议级合规性控制的“虚拟钱包”,允许更广泛的开发人员社区访问Libra网络。

在Libra最初白皮书中,我们宣布了最终将Libra网络过渡到一个无需许可系统的路线图。从那以后的几个月中,我们听到了外界的一个主要担忧——天秤座协会(Libra Association)在维持网络合规性条款时将面临挑战。在这次白皮书更新(Libra 2.0)中,我们介绍了我们正在探索的方法,以使网络的新进入者能够竞争提供核心网络服务并参与Libra网络的治理,同时确保天秤座协会满足监管要求的能力。单击此处获取更多信息。

 

2 除了多货币稳定币外,还提供单货币稳定币 

 

天秤座(Libra)网络旨在成为一种全球可访问的低成本支付系统,是对当地货币的补充而不是替代。 稳定货币和价值保全是在公共部门专有职权范围内的关键努力。 因此,我们通过添加单货币稳定币(例如,Libra≋美元,Libra≋欧元,Libra≋英镑等)来增强Libra网络。 我们希望与世界各地的监管机构,中央银行和金融机构合作,随着时间的推移,扩大Libra网络上可用的单一货币稳定币的数量,并探索与他们进行直接监管的技术,运营和法律要求。

 

3 分阶段部署天秤座网络

 

自2019年6月公开以来,我们已经与世界各地的决策者进行了讨论,以确定适当的分阶段推出计划。最初,只有指定经销商和受监管的VASP才能访问该网络,而Libra协会则根据从监管机构收到的反馈意见,继续开发其他VASP的认证流程以及针对无托管钱包(unhosted wallets)的合规框架。Libra协会打算在相关合规框架最终确定之后,让经认证的VASP和无托管钱包可以访问该网络。

通过我们在使用Move语言构建白皮书中描述的功能的过程中的经验,我们能够亲眼看到可编程金融基础设施的潜力。例如,Move泛型允许我们为单货币稳定币创建简单的API。

Libra协会致力于对智能合约实施适当的审查和风险控制。首先,只有该协会批准和发布的智能合约才能与Libra支付系统直接交互。随着时间的推移,协会将探索适当的控制措施,以允许第三方发布智能合约。

 

保持更新

 

我们知道,由于我们的分阶段推出计划,对一些开发者来说,无法立即使用Libra网络的所有方面,但是我们很高兴与社区合作以推动这些功能的发展。

有关更多详细信息,请查看Libra网络的文档和社区站点。 我们还邀请您参加我们的Libra测试网络的开源早期预览版。 我们希望您继续阅读,构建并提供反馈!
