定義
DID
Decentralized Identifier
DID 是一種數位身分標識。它幫助持有者和驗證方確認某個身分由誰控制，也讓一項聲明有明確的關聯對象。帳戶、登入和授權各自仍有自己的角色。

延伸閱讀與實踐
學習
- Understand identity and credentials
Distinguish identifiers, control, claims and application requests.
- What does a DID identify?
Distinguish the identifier, its document and its subject.
- Does control prove real-world identity?
Proving control of an identifier and establishing a real-world identity are different tasks.
- How does did:abt relate to DID Core?
DID Core supplies a shared model; each method supplies its own rules.
- Must a DID depend on a blockchain?
Identifiers and verifiable registries can combine without being synonyms.
- Are agent identity and permission the same?
Separate persistent naming, proof of control and authority for an action.
文章
- Real user sovereignty: freedom to choose, freedom to move
Why Arc separates identity, data and compute: ownership should let you change services while keeping your identity, records and AI memory under your control.
- DiscussKit, Rebuilt on ARC
DiscussKit has been rebuilt on ARC, and ArcBlock Community has completed its move. This is a new division of responsibility across discussions, identity and user-owned data.
- Why We Built Aside
We watched great tools change hands or disappear. That is why ArcBlock built Aside: an ARC-powered iPhone app that sends every Share back to a place you own.
- CLARITY Act or Not, Let’s Clarify ABT
Clear law matters, but a product must also explain what its token does, who controls it, what rules apply, and how participants reconcile the record.
- What's next: ARC, one real application at a time
The new site is live. Here is how we plan to bring ARC into the community, data spaces and everyday applications, with migrations, new products and builders taking part along the way.
- A Useful Token Must First Stand for Something of Real Value
AI services already use credits to meter storage, compute, and API calls. As Agents begin to act across systems, the important work is not giving those units a fashionable name. It is making the rights, authority, and usage they represent possible to verify and reconcile.

術語
- Agent
當 agent 代表人或服務完成一項工作，真正需要說明的是三件事：誰在行動、代表誰、這次行動被允許做什麼。把它們分開，授權和後續核驗才有明確對象。
- Decentralized Identity
一種做法：識別碼和關於它的聲明由主體自己持有、由驗證方自己核對，而不是存放在某一家服務商的帳號體系裡。DID 和可驗證憑證是讓它可行的兩塊。
- DID Document
DID Document 描述與 DID 關聯的驗證方法和服務。W3C 定義共同的資料模型；解析一個 DID 仍需要支援對應的方法。應用自行判斷接受哪些金鑰、用途與簽發方。
- did:abt
ArcBlock 的 DID 方法，使用 did:abt: 命名空間識別帳戶、資產及其他物件。解析器需要支援這一方法。
- Self-Sovereign Identity
一種主張：人應當自己持有識別碼和憑證，並且每次自己決定揭露什麼。它講的是控制權歸誰，不是一套協定；去中心化身分是把它建出來的方式。
- 區塊鏈
透過密碼學連接記錄，並按共同的驗證與共識規則確定交易歷史的分散式帳本。
