OpenMLS

Protocolo P2P

A Rust implementation of the Messaging Layer Security (MLS) protocol as specified in RFC 9420. It is a software library meant to be a building block for applications that need end-to-end encryption of group messages, with an interface that hides the complexity of the underlying cryptography. OpenMLS does not implement its own primitives: it relies on pluggable cryptography providers (a RustCrypto-based one and a libcrux-based one) and storage providers (in-memory, SQLite and others). It supports three ciphersuites, builds for several platforms including WebAssembly, and provides an interoperability client and a delivery-service example. It is the reference-style Rust implementation of the standard that has its own entry in this matrix as MLS (Messaging Layer Security) .

Arquitetura P2P Protocol library for end-to-end encrypted groups; MLS expects a delivery service to carry messages, which OpenMLS provides only as an example, so it is transport-agnostic rather than peer-to-peer by itself
Rede de Sobreposição None: OpenMLS defines no network
Endereçamento por Conteúdo No.
Local-First Not a data layer; group state is held by each client
Criptografia de Ponta a Ponta (E2EE) Yes: end-to-end encryption of group messages, as defined by MLS (RFC 9420)
Biblioteca de CRDTs No: not a CRDT library.
Tolerância a Falhas Bizantinas Partial: MLS detects invalid commits and OpenMLS offers fork-resolution helpers; it is not a consensus protocol
Assinatura Yes: members authenticate with signature keys in credentials, as MLS specifies
Permissões Group membership is managed through MLS proposals and commits by members; no separate permission model is described in the README
Compatibilidade com a Web Semântica N/A: no RDF, JSON-LD or SPARQL layer.
Contrato Inteligente N/A: no ledger or smart-contract component.
Posição na Pilha de Protocolo Application-layer cryptographic protocol, independent of transport
Incorporação de Ativo / Valor None: no token or value-transfer mechanism.
Maturidade / Padronização do Protocolo Implements an IETF RFC (9420); the library itself is pre-1.0 and supports three ciphersuites
