Cardano

Protocolo P2P

A Layer-1 blockchain using the Ouroboros family of provably-secure Proof-of-Stake protocols, developed with an academic-peer-review-driven research methodology. Governance transitioned in the "Voltaire" era to on-chain mechanisms (CIP-1694): DReps (delegated representatives) vote on governance actions including protocol parameter changes and treasury spending, alongside a Constitutional Committee and SPOs (stake pool operators). The cardano-node repository is now maintained under IntersectMBO (renamed from the original Input Output HK organization in 2023).

Detalhes

Licença Apache-2.0
Status de Dev 🟢 Ativo
Proprietário IntersectMBO (the current organizational steward of core development, successor structure to IOG/IOHK); Cardano Foundation (standards/ecosystem stewardship) and Emurgo (commercial arm) are the other two "founding trio" entities.
Órgão de Governança Post-Voltaire on-chain governance (DReps + Constitutional Committee + SPOs voting on governance actions) — a genuinely live, binding mechanism, not just a roadmap intention.
País N/A (IntersectMBO/Cardano Foundation/Emurgo are separately-registered entities across multiple jurisdictions)
Ano de Início 2017
Stack Haskell (core node), with Plutus (Haskell-based) as the smart-contract language.
Financiamento Historically IOHK-contracted development funding; now also a substantial on-chain Treasury funded by a percentage of transaction fees/protocol rewards, allocated via the on-chain governance process itself (Catalyst funding rounds, treasury withdrawals via DRep/Constitutional Committee approval).

Protocolo P2P Atributos

Origens Academic-peer-review-driven L1, Ouroboros PoS consensus family, three-entity founding structure (IOHK/IntersectMBO, Cardano Foundation, Emurgo).
Banco de Dados N/A conventional DB; third-party indexers (Blockfrost, Koios) built on top, not part of the core node.
Linguagem de Consulta N/A conventional query language; third-party indexer APIs.
Formatos de Dados CBOR.
Edição Colaborativa em Tempo Real N/A
Edição de Texto Rico N/A
Suporte Móvel Via third-party wallets (Daedalus, Eternl, Yoroi, etc.).
Suporte Web Via third-party wallets and dApp frontends.
Aplicativos Nativos cardano-node ships as a binary; Daedalus is a full-node desktop wallet.
Termos Free, open-source; network fees paid to SPOs, with a portion routed to the on-chain Treasury.
Fundos On-chain Treasury (see Governing Body) — a real, disclosed, protocol-level treasury, unusual among this batch.
Baseado Em Novel Ouroboros consensus family; not forked from a prior chain.
Arquitetura P2P Stake-pool-operator (SPO) gossip network; Ouroboros epoch/slot-leader election determines block producers.
Rede de Sobreposição Global, permissionless (SPOs require stake delegation, not permission).
Endereçamento por Conteúdo No.
Local-First N/A
Criptografia de Ponta a Ponta (E2EE) N/A
Biblioteca de CRDTs N/A
Tolerância a Falhas Bizantinas Yes — Ouroboros (provably secure PoS, peer-reviewed).
Assinatura Ed25519.
Permissões Permissionless for transacting; SPO operation requires stake delegation but not central approval.
Compatibilidade com a Web Semântica No.
Contrato Inteligente Yes — Plutus (Haskell-based, since the 2021 Alonzo upgrade).
Posição na Pilha de Protocolo Base-layer settlement + execution (Layer 1), extended UTXO ("eUTXO") accounting model.
Incorporação de Ativo / Valor Native (ADA) plus native multi-asset support (tokens are a first-class ledger feature, not requiring smart contracts).
Maturidade / Padronização do Protocolo Mature, mainnet since 2017, CIP (Cardano Improvement Proposal) process, live on-chain governance since Voltaire/CIP-1694.
