NEAR Omni Bridge explained: chain signatures replace light client bridges
Quote219 words
Explains how Omni Bridge uses threshold MPC chain signatures instead of light client verification, cutting cost and verification time. It works with chains lacking smart contracts, including Bitcoin, and scales linearly instead of quadratically across chains.
Key claims
Verification via one 65-byte signature vs roughly 500KB block headers
Gas costs down up to 90% vs light client bridges
Bridges have lost over $2B to hacks
Linear O(n) scaling vs O(n squared)
NEAR's Omni Bridge is crucial multichain infra, making cross-chain transactions 90% cheaper and 50x faster with best-in-class security.
Powered by Chain Signatures, $NEAR accounts, contracts & AI agents can now move assets seamlessly across any chain (incl. Bitcoin).

1/ Omni Bridge by @NEARProtocol cuts transaction verification times from hours to minutes, while reducing gas costs by up to 90% compared to traditional light client bridges (such as the Rainbow Bridge).
2/ Traditional light client bridges require full block header verification (~500KB).
Omni Bridge's Chain Signatures enable verification with a single 65-byte signature, maintaining security while dramatically reducing costs and verification times.
3/ While major bridges have lost over $2B to hacks in the past, Omni Bridge's threshold MPC architecture requires a supermajority of validators to be compromised simultaneously, preventing single points of failure.
4/ Unlike other cross-chain solutions, Omni Bridge works with any blockchain (including Bitcoin) without requiring smart contract capabilities on the destination chain.
Omni Bridge enables direct Bitcoin transfers through deterministic address derivation and MPC-signed transactions.
5/ Additionally, traditional bridges create O(n虏) complexity when connecting multiple chains.
Omni Bridge's architecture achieves O(n) linear scaling, dramatically simplifying multi-chain integration.
6/ Omni Bridge matters.
$NEAR matters.
In hindsight it will have been obvious.
7/ More about Chain Signatures below.
