add(support for multiple chains)

[dcbuild3r]

Propagate the latest root hashes and timestamps to many different rollups, validiums, and other scaling solutions.

Requirements

• [ ] Switch from pull-based to push-based approach (spec)

TODO

• [ ] Add methods on proxy contract to abstract L1<>L2 communication with all supported chains
• [ ] Build a public entry method from world-id-contracts that will call the methods for the other chains, passing the latest state root hashes and timestamps from the external service
• [ ] Add monitoring to make sure data hits all the target contracts on L2s
• [ ] Bonus: Make the service call a chain-specific contract method if L1<>L2 comms fail

[dcbuild3r]

this will most likely not be pursued as storage proofs are looking like a viable alternative. re: Herodotus integration.

Right now the world-id-state-bridge contracts support Optimism and Polygon for launch. However, the next iteration will most likely use storage proofs. List of supported networks by Herodotus

[dcbuild3r]

Interesting candidates for OmniChain WorldID integrations:

• Herodotus (L1<>L2 comms, snarkified storage proofs)
• Axiom (L1<>L2 comms)
• Succinct (Telepathy L1<>L1 comms)
