Where does value flow in crypto?



Optimism Bridge

The Optimism Bridge is the native bridge of the Optimism rollup, which allows any ERC-20 asset to be bridged from Ethereum mainnet into Optimism. The bridge inherits the security of Ethereum, although the Optimism maintains upgrade keys which can change the bridge code.

Security Assumptions

• 1/n verifiers watching for malicious transactions publish a fraud-proof when fraud occurs.

• Verifiers are able to publish a fraud-proof inside the 7-day dispute period.

• Liveness of Optimism's sequencer, which is currently run by a single centralized entity (though this can be bypassed via canonical transactions on Ethereum).
