# Technical implementation

## Indexing Ordinals

We are in the process of developing custom indexers, essentially Bitcoin nodes designed to index the Ordinals and interpret BRC-20-defined protocols. Additionally, we have implemented customization to include ETH receiving addresses as metadata when recording 'transfer' on BRC-20 protocols for bridging functionality purposes.

## Multi-Signature Validation

 Multi-signature validation processes each inscription within the bundle, deducting gas fees and distributing them among validators based on their Bitcoin addresses. Valid operations in the Bitcoin network trigger multi-signature validation, updating the state and address balances in the Ethereum network. The validation degree and consensus mechanism are adjustable based on the system's security requirements

## Factory Smart Contract

On the Ethereum side, we are actively developing a permissionless smart contract responsible for minting wrapped tokens on the ETH chain. As an integral step in our bridging process, the factory smart contract will dynamically create a token contract mirroring the original BRC-20 token name, prefixed with the letter "w" to signify its status as a wrapped asset.
