On pre-alpha testnet, Lumoz has a cross-chain bridge that supports asset interoperability between ETH, and other public chains to the Lumoz chain. This bridge uses chainsafe’s solution and is run by the trusted Lumoz official team. Deposit events on one chain are detected by a set of trusted off-chain relays, which wait for a final determination, submit the event to another chain, and vote on the submission to reach acceptance to trigger the appropriate handler.
We will evaluate the chains' security, decentralization, and asset richness and choose which public chains to use as ZK-Rollup‘s Layer 1. In the future, we will hand over the choice to the community through DAO. The community can vote to add more decentralized public chains and corresponding assets to the asset layer.
