Rede Cosmos
Ecossistema de blockchains soberanas e interoperáveis conectadas pelo protocolo IBC, construídas com o Cosmos SDK e protegidas pelo consenso CometBFT.
Cosmos foi proposto em 2016 por Jae Kwon e Ethan Buchman. O Cosmos SDK fornece módulos pré-construídos para staking, governança e IBC. Projetos notáveis: Osmosis, Kava, Binance Chain.

🧒 Explique como se eu tivesse 5 anos
Imagine que cada país tem seu próprio governo, leis e moeda ([blockchain](/pt/terms/blockchain)). Agora todos constroem o mesmo sistema de trem de alta velocidade (IBC) entre as capitais para transferir dinheiro e bens instantaneamente. Isso é o Cosmos: países independentes que se comunicam perfeitamente.
🤓 Expert Deep Dive
CometBFT (antigo Tendermint) é um motor de consenso BFT com finalidade instantânea. O IBC (ICS-002 a ICS-004) permite transferências trustless entre cadeias via light clients. O Interchain Security (2023) permite que novas cadeias aluguem a segurança dos validadores do Cosmos Hub.
❓ Perguntas frequentes
What is ATOM used for?
ATOM is the native token of the Cosmos Hub. It is used for: 1) Staking (delegating to validators to secure the network and earn rewards), 2) Governance (voting on protocol upgrades and parameter changes), and 3) Paying transaction fees on the Cosmos Hub.
What is the difference between the Cosmos Network and the Cosmos Hub?
The Cosmos Network refers to the entire ecosystem of IBC-connected chains. The Cosmos Hub is one specific blockchain within that ecosystem — the first and most prominent Hub, which hosts the ATOM token and provides Interchain Security services.
Does Cosmos compete with Ethereum?
They take different philosophies. Ethereum aims to be a single, shared execution environment where all apps run on the same chain. Cosmos advocates for 'app-chains' — each application having its own dedicated blockchain, with IBC enabling communication between them.
