Última Investigação 1 de jul. de 2026
Protocolo P2P Atributos
Origens Created by Gavin Wood (Ethereum co-founder and former CTO) after leaving Ethereum in 2015 to pursue a more interoperable multi-chain architecture; whitepaper published 2016
Banco de Dados Relay chain state; parachain state managed independently per chain
Linguagem de Consulta None native
Formatos de Dados SCALE codec; XCM message format
Edição Colaborativa em Tempo Real No
Edição de Texto Rico No
Suporte Móvel Via wallets and parachain-specific apps; no native protocol-level mobile SDK
Suporte Web Yes — via Polkadot.js and parachain-specific interfaces
Aplicativos Nativos Yes — Polkadot SDK for building chains; various wallet and staking apps
Termos Apache 2.0 / GPL
Fundos Web3 Foundation grants program (open, 300+ projects funded globally); DOT treasury via OpenGov
Baseado Em Ethereum (conceptual origins; Gavin Wood co-founded both); BABE derived from Ouroboros Praos; NPoS consensus mechanism
Arquitetura P2P Relay chain + parachain model; validators on relay chain verify parachain state transitions submitted by collators; nominators delegate stake to validators
Rede de Sobreposição Relay chain serves as coordination and security layer; parachains connect to it via coretime allocation
Endereçamento por Conteúdo Partial — block hashes used for state verification; no IPFS-style content addressing
Local-First No
Criptografia de Ponta a Ponta (E2EE) No native E2EE at protocol level
Biblioteca de CRDTs No
Tolerância a Falhas Bizantinas Yes — GRANDPA finality gadget provides Byzantine fault-tolerant finality
Assinatura Sr25519 (Schnorrkel); Ed25519; ECDSA
Permissões Permissionless for validators (via NPoS staking) and parachain deployment (via coretime purchase with DOT)
Compatibilidade com a Web Semântica No
Contrato Inteligente Yes — via parachains (e.g., Moonbeam for EVM-compatible smart contracts; ink!/PolkaVM for Wasm contracts)
Posição na Pilha de Protocolo Layer 0
Incorporação de Ativo / Valor Yes — DOT native token for staking, governance, and coretime; parachain-native tokens; Asset Hub system parachain for multi-asset management
Maturidade / Padronização do Protocolo De Facto Standard — mainnet live since 2020; large active ecosystem; not submitted to formal standards body
