MAP Protocol serves as a Bitcoin layer-2 dedicated to Bitcoin ecosystem development. It also provides the essential infrastructure for achieving interoperability among blockchain-based assets, storage, and computing. Built upon the light client and zero-knowledge proof technology, our interoperable cross-chain solution is peer-to-peer, without any trusted third-party entities, thus turning siloed blockchains or blockchains using third-party bridges into an all-in-one Web3 development platform and Web3 user gateway.

Due to the lack of Turing completeness, Bitcoin is limited in its usability compared to Ethereum, and its ecosystem grows slowly. As a Bitcoin layer-2 and an interoperable omnichain infrastructure, MAP Protocol is able to expand the Bitcoin ecosystem’s interoperability and fuel the growth of the Bitcoin community.

With MAP Protocol’s BRC-201, a cross-chain extension protocol to BRC-20 tokens, BRC-20 and ORC-20 assets on the Bitcoin network can interact with other tokens on other public chains. This layer of Bitcoin network cross-chain interoperability will also grow the Bitcoin community as a whole.

First proposed in the form of Simplified Payment Verification (or SPV) in Satoshi Nakamoto’s 2008 whitepaper, light client is a way to allow less powerful clients to interact with the network with as many security guarantees as possible. Zero-knowledge proof was first suggested by Manuel Blum, Paul Feldman, and Silvio Micali in 1989 and now has use cases in anonymous payments, authentication, verifiable computation, and on-chain voting.

MAP Protocol has refactored light clients technology with ZK-proof, which further improves light client verification efficiency while keeping the whole verification process peer-to-peer without trusting any third party.

Today, most interoperability solutions only emphasize asset cross-chain transactions. However, a truly interoperable Web3 future extends beyond that — it's a future where dApp operations including transactions, data storage, and computing are performed on the blockchain and are interoperable across different chains, giving users full control over their data and privacy.

MAP Protocol paves the way for this truly interoperable Web3 future. Through MAP Protocol, developers can seamlessly integrate various blockchain components, enabling the construction of apps where all operations are on-chain. This provides users with complete control over their data and assets across multiple chains.

MAP Protocol and its apps are transparent and open source, making it the go-to solution for all your blockchain interoperability needs. Whether you wish your chain to connect with another blockchain, build a dApp to operate across multiple blockchains, or even to interact with the Bitcoin ecosystem, we make it easy for you to build anything omnichain and fully on-chain.
