CosmosIntermediateCosmos chains secure themselves and connect through IBC, while Polkadot parachains rent shared security with DOT and message through XCM. This guide compares both, including coretime, JAM and the Cosmos Hub's 2026 removal of Interchain Security.

GeneralIntermediateA bridge moves value between blockchains by locking an asset on one chain and minting a representation on another. They get hacked because they concentrate value and depend on flawless keys, contracts and proofs — as Ronin (~$600M) and Wormhole (~$320M) showed.

EthereumIntermediateA layer 2 runs on top of a base chain like Ethereum for cheap, fast transactions while inheriting its security. Rollups execute off-chain, then post compressed data back to Ethereum — optimistic ones use fraud proofs, zk ones use validity proofs.
