Migrating both networks to a single shared ledger

Establishing a trusted mechanism to verify and relay the smart contract call across networks

Ensuring both networks have the same native token

Ensuring both networks use the same consensus algorithm

Use a bridge to transfer the raw anonymized data to the public chain

Use a notary to manually approve each data transfer

Replicate the entire private ledger on the public chain

Transfer only cryptographic hashes of the anonymized data to the public chain
