The Mechanics of Linea Bridges

Linea bridges operate on a sophisticated mechanism that ensures the secure and efficient transfer of assets between networks.

1. Asset Lock and Verification: When a user initiates a transfer from Ethereum to Linea, the assets are locked in a smart contract on the Ethereum mainnet. This lock is verified through a series of cryptographic checks to ensure the validity of the transaction.
2. Zero-Knowledge Proof Generation: A zero-knowledge proof is generated, verifying the validity of the locked assets without revealing specific transaction details. This proof is compact and can be quickly verified on the destination chain.
3. State Update and Minting on Linea: Based on the verified proof, the state of the Linea network is updated, and equivalent assets are minted. This process is near-instantaneous, allowing users to access and utilize their assets within the layer-2 ecosystem almost immediately.
4. Batched Settlements: To optimize gas costs and improve efficiency, multiple transactions are often batched together and settled on the Ethereum mainnet periodically.
5. Withdrawal Process: When moving assets back to Ethereum, the process is reversed. Assets are burned on Linea, a withdrawal proof is generated, and after a security waiting period, the original assets are unlocked on Ethereum.
6. Fraud Proofs and Challenge Period: To ensure the utmost security, a challenge period is implemented where validators can submit fraud proofs if they detect any irregularities in the bridging process.

This sophisticated process ensures that the total supply of assets remains constant across networks, maintaining the integrity of the ecosystem while providing users with a seamless experience.
