研究如何利用为受监管金融工具设计的基础设施解决学术证书验证难题，通过结合OnchainID和T-REX套件设计注册系统，实现身份绑定、链上认证等功能，经参考实现验证及多方面评估，明确相关矛盾与保证。
AI 中文摘要
验证学术证书仍然困难重重：记录由各机构保存在专有系统中，验证缓慢且需人工操作，伪造学历现象普遍。基于区块链的注册系统被提议作为一种补救措施，但现有系统往往仅锚定证书哈希值，却未将其与可验证身份绑定，缺乏明确的发行机构认证机制，且不支持证书发行后进行更正或撤销。本文研究为受监管金融工具设计的基础设施能否被重新利用以弥补这些差距。我们展示了一个用于身份绑定学术证书的注册系统设计，该系统将OnchainID自主身份（ERC-734/ERC-735）与T-REX套件（ERC-3643）相结合：其可信发行机构注册系统成为链上发行机构认证白名单，每个证书都表示为一个绑定到学生身份的签名、可更新声明，任何无钱包的第三方均可验证，同时敏感字段保存在链下。我们明确了可转让安全令牌标准与不可转让证书之间的矛盾，并阐明了哪些保证可以延续。我们用一个涵盖完整证书生命周期的参考实现来验证该设计，并从燃气成本、可扩展性、延迟和安全性方面对其进行评估，量化相对于哈希锚定基线的开销。
英文摘要
Verifying academic credentials remains difficult: records are held by individual institutions in proprietary systems, verification is slow and manual, and counterfeit qualifications are widespread. Blockchain-based registries have been proposed as a remedy, but existing systems tend to anchor certificate hashes without binding them to a verifiable identity, without an explicit mechanism to accredit issuing institutions, and without support for correcting or revoking credentials once issued. This paper investigates whether an infrastructure designed for regulated financial instruments can be repurposed to close these gaps. We present the design of a registry for identity-bound academic credentials that composes OnchainID self-sovereign identities (ERC-734/ERC-735) with the T-REX suite (ERC-3643): its trusted-issuer registry becomes an on-chain issuer-accreditation whitelist, and each certificate is represented as a signed, updatable claim bound to a student's identity and verifiable by any third party without a wallet, while sensitive fields are kept off-chain. We make explicit the tension between a transferable-security-token standard and non-transferable credentials, clarifying which of its guarantees carry over. We validate the design with a reference implementation covering the full certificate life cycle and evaluate it in terms of gas cost, scalability, latency, and security, quantifying the overhead relative to a hash-anchoring baseline.
