Cosmos can -have multiple hubs, but this overview will consider a single hub. Each zone must maintain its own -state and therefore have its own validator community. When a zone wants to communicate with another -zone, it sends packets over IBC. The Hub maintains a multi-token ledger of token balances -(non-transfer messages are relayed but their state not stored in the Hub). - -Zones monitor the state of the Hub with a light client, but the Hub does not track zone states. -Zones must use a deterministic finality algorithm (currently, all use Tendermint) and implement the -IBC interface to be able to send messages to other chains through the Hub. - -Cosmos can also interact with external chains by using "peg zones", which are similar to bridged -parachains. +Cosmos is a network of blockchains built using [CometBFT](https://cometbft.com/) as the consensus engine, [Cosmos SDK](https://docs.cosmos.network/) as the VM, and [IBC](https://ibcprotocol.dev/) which allows chains to interoperate with one another. + +IBC leverages light clients that can keep track of the consensus of a counterparty chain. For example, when chains A and B want to talk to one another, chain A uses its light client of B to verify messages sent from chain B, and vice versa. IBC is [currently live](https://app.trustless.zone/?from=POLKADOT&to=OSMOSIS) on Polkadot and Kusama. Work is ongoing to implement IBC to Ethereum and it's layer 2s. ## Consensus
