<p>Decentralized Identifiers (DIDs) are a new type of identifier intended for verifiable digital identity that is "self-sovereign", fully under the control of an entity and not dependent on a centralized registry, identity provider, or certificate authority.</p>
<p>DIDs resolve to DID Documents — simple documents that contain all the metadata needed to interact with the DID. Specifically, a DID Document typically contains at least three things.</p>
<ul>
<li>The first is a set of mechanisms that may be used to authenticate as as a particular DID (e.g. <strong>public keys</strong>, pseudonymous biometric templates, etc.).</li>
<li>The second is a set of <strong>authorization information</strong> that outlines which entities may modify the DID Document.</li>
<li>The third is a set of <strong>service endpoints</strong>, which may be used to initiate trusted interactions with the entity. This document specifies a common data model, format, and operations that all DIDs support.</li>
</ul>
<p>Decentralized Identifiers (DIDs) as personal trust anchors. Anyone can propose a DID method — ideally they leverage the power of blockchains, but a blockchain is not required. There are DID methods being proposed for public blockchains (Bitcoin, Blockstack, Ethereum), private blockchains (Sovrin/Indy), non-blockchain (IPFS), and even legacy web-of-trust identity systems (PGP).</p>
<p>Decentralized identifier (DID) is simply a new type of globally unique identifier with special features designed for blockchains. But at a deeper level, DIDs are actually the tip of the iceberg or the tip of the spear of <strong>an entirely new layer of decentralized digital identity and public key infrastructure (PKI) for the Internet</strong>. This decentralized public key infrastructure (DPKI) could have as much impact on global cybersecurity and cyber-privacy as the development of the SSL/TLS protocol for encrypted Web traffic (now the largest PKI in the world).</p>
<p>目标：cross-chain rooting, indexing, and resolution of decentralized identifiers and names.</p>
