标题： Programmable Governance for Group-Controlled Decentralized Identifiers

摘要： 自主权身份（SSI）是一种数字身份管理的范式，提供了独特的隐私优势。 SSI中的关键技术是去中心化标识符（DIDs）及其相关元数据，即DID文档（DDOs）。 DDOs包含关键的验证材料，例如由DID标识的实体（即DID主体）的公钥，并通常锚定在分布式账本上以确保安全性和可用性。 长期有效的DIDs需要支持更新（例如密钥轮换）。 理想情况下，只有DID主体应授权DDO更新。 然而，在实际应用中，更新权限可能会被共享或委托。 虽然DID规范承认这些情况，但它并未定义当多个实体共同控制一个DID（即群体控制）时应如何授权更新。 本文研究了链上无信任机制的实现，使在群体控制下的DID控制器能够编程其治理规则。 主要研究问题是：能否开发一种技术机制，以与链无关且可适应的方式协调DDO的链上群体控制？ 显示英文摘要

摘要： Self-Sovereign Identity (SSI) is a paradigm for digital identity management that offers unique privacy advantages. A key technology in SSI is Decentralized Identifiers (DIDs) and their associated metadata, DID Documents (DDOs). DDOs contain crucial verification material such as the public keys of the entity identified by the DID (i.e., the DID subject) and are often anchored on a distributed ledger to ensure security and availability. Long-lived DIDs need to support updates (e.g., key rotation). Ideally, only the DID subject should authorize DDO updates. However, in practice, update capabilities may be shared or delegated. While the DID specification acknowledges such scenarios, it does not define how updates should be authorized when multiple entities jointly control a DID (i.e., group control). This article examines the implementation of an on-chain, trustless mechanism enabling DID controllers under group control to program their governance rules. The main research question is the following: Can a technical mechanism be developed to orchestrate on-chain group control of a DDO in a ledger-agnostic and adaptable manner?
