Detalhes
Licença The specification is under the W3C Patent Policy (2004) terms and any sample or reference code in the repository is Apache-2.0, per the repository's licence file, which inherits them from the Decentralized Identity Foundation project charter . https://github.com/swcurran/didvh
Status de Dev 📝 Rascunho
Proprietário No organization is named; the specification lists a single editor and is developed in a personal GitHub repository
Órgão de Governança None named. Developed in the open by a single editor; related specifications VH-Log and did:webvh are separate projects
País Not stated by the project.
Ano de Início 2026
Stack JSON Lines DID log (did.jsonl) of signed, hash-chained entries; witness proofs in did-witness.json; did:key for witness identifiers; cryptographic agility through versioned parameters
Financiamento Not stated by the project.

Protocolo de Identidade Atributos
Origens Making self-certifying DIDs with verifiable history usable where there is no web host: peer-to-peer exchange, local files, content-addressed storage, by separating the identifier from the place its log lives
Banco de Dados None: each DID's history is its own JSON Lines log, held by the controller and by whoever else copies it (peers, watchers, a web location, IPNS or a local directory)
Linguagem de Consulta None: the resolver is passed the log (or a source reference), verifies every entry and returns the DID document
Formatos de Dados JSON Lines DID log (did.jsonl) of entries whose state is a W3C DID document; witness proofs in did-witness.json; parameters such as method version, update keys and next-key hashes
Suporte Móvel
Suporte Web Not stated by the project; a log may be published at a web location, but the DID itself contains none
Aplicativos Nativos None: a draft specification
Termos Free; specification and sample code licences as above
Fundos
Baseado Em VH-Log; did:webvh (log format, SCID, entry hashes, key authorization, pre-rotation and witnesses are those of VH-Log as used by did:webvh); W3C DID Core; did:key for witnesses
Permissões Cryptographic capabilities: only keys authorized in the log can update the DID; anyone can verify
Autenticação e Identidade Self-certifying: the DID is the SCID derived from the first log entry; entries are signed by keys the log itself authorizes; every entry's identifier must match the first entry's SCID
Modelo de Armazenamento Storage-agnostic: the controller must make the log available through at least one source (peers, watchers, web locations, IPNS, a local directory), and a resolver verifies it the same way whichever way it arrived
Interoperabilidade A W3C DID method in a draft; sibling of did:webvh and meant to coexist with it; the did:scid method defines a did:scid:vh format over the same log, and the spec notes a did:vh, a did:scid:vh and a did:webvh DID can never share a log or a SCID
Portabilidade de Dados Complete by design: the DID never changes, so no portability mechanism is needed, and the same log can be served from any source
Governança e Tomada de Decisão Not described: the specification is a personal draft with no process stated
Maturidade / Padronização do Protocolo Editors Draft v0.1 ("Pre-Draft"); no standards body is named, no implementation or test suite is linked, and it is not in the W3C DID Extensions registry
Padrões de Identidade W3C DID Core; VH-Log; did:key for witness identifiers
Padrões de Identidade - Lista
Métodos DID Suportados did:vh (defines this method); witnesses must be did:key
Métodos DID Suportados - Lista
Gestão de Chaves Keys authorized in the log; optional pre-rotation by publishing hashes of the next keys (the spec says controllers should use it); updates signed by an authorized key
Tipos de Credenciais N/A: a DID method; it defines no credential types
Tipos de Credenciais - Lista
Método de Verificação A resolver verifies every log entry (entry hash, SCID, authorized-key signatures, pre-rotation and witness proofs where used) and checks that each entry's identifier is did:vh plus the first entry's SCID
Recursos de Privacidade Described in the spec's privacy considerations, covering surveillance and correlation and the right to erasure; the log is append-only, so history cannot be erased
Métodos de Autenticação Signatures by keys the log authorizes; witnesses can approve updates before publication
Mecanismo de Revogação Deactivation by setting the deactivated parameter or emptying the update keys; the history is kept
Tipos de Agentes Suportados Any key-controlling entity
Tipos de Carteira/Cliente None yet: no implementation is linked
Mecanismos de Recuperação Pre-rotation commitments (optional, recommended) let a controller recover from a compromised active key
Conformidade / Regulamentações The spec has a section on the right to erasure under GDPR Article 17
Protocolos de Troca de Credenciais N/A: a DID method; its logs can be exchanged peer-to-peer in the manner of did:peer
Protocolos de Troca de Credenciais - Lista
Estrutura de Confiança Cryptographic: the SCID and the entry hashes bind the log to the identifier; optional witnesses and watchers add third-party checks; no registry or authority
Modelo de Custo Free: no registry or host is required
Resistência à Censura High by design: there is no authoritative location, so nobody can block resolution by controlling a host; availability still depends on someone holding a copy of the log
