Cross-chain Bridging

What is Cross-chain Bridging

Cross-chain bridging is the capability of Humanode Biomapper that allows users to prove uniqueness on other Ethereum-compatible chains beyond Humanode.

How it Works

Biomapper itself run on the Humanode chain. Once verified, they can bridge their biomap to other supported blockchains (in short).

This allows the dApps on those chains to run on-chain uniqueness checks on addresses just like it works on the Humanode chain.

Technical Details

Biomapper is a smart contract on the Humanode chain. BridgedBiomapper is a counterpart contract on each of the supported bridged chains.

The information between those smart contract is transferred by the users. Any user can bring their Biomapper state to the Bridged Biomapper on a particular chain.

The API of the Biomapper and/or BridgedBiomapper smart contracts is available as part of the Biomapper SDK.
