Interoperable BTC L2
Use MAP Protocol
Welcome to MAP Protocol
MAP Protocol is a Bitcoin layer-2 for peer-to-peer cross-chain interoperability.
The Layer 0 of Bitcoin L2s, interoperating between the Bitcoin ecosystem and other ecosystems
By leveraging the security mechanisms of the Bitcoin network, MAP Protocol's security is ensured by the Bitcoin network, and asset cross-chain between Bitcoin L1 and L2 is achieved through the BRC201 protocol. At the same time, through the successful development of cutting-edge ZK-LightClient technology, peer-to-peer interoperability among various Bitcoin L2s, as well as interoperability between other public chains and the Bitcoin network, are achieved.
The Bitcoin-level peer-to-peer cross-chain network
Similar to the “purely peer-to-peer” Bitcoin network, MAP Protocol’s cross-chain network is also peer-to-peer without going through any third party. The validity of a cross-chain request depends purely on the fact that it has occurred on the source chain, not on decisions or proofs made by trusted third parties.
Building Applications that Cover All Bitcoin L2s
Various Bitcoin L2s should be an integrated whole, not fragmented. We provide developers with a full set of development tools, tutorials, and SDKs. Through MAP Protocol's Bitcoin L2 network, developers can build cross-chain dApps that cover all Bitcoin Layer 2s as easily as building applications on a single chain.
The infra for interoperable on-chain assets, storage, and computing
Interoperability goes beyond connecting different tokens on different chains. A truly decentralized Web3 is where assets, storage, and computing are all on-chain and interoperable. We provide the infrastructure for interoperable on-chain assets, storage, and computing.
Get started
MAP Protocol is the gateway for users to enter the Bitcoin ecosystem and interact with the entire interoperable blockchain world. Here are some simple steps to help users quickly experience this continuously evolving technology.
Start with a Wallet
Find the wallet that allows you to connect with MAP Protocol and manage your funds.
Get some MAPO
MAPO is the currency of MAP Protocol — you can use it for various purposes.
Try decentralized exchanges (DEXs)
DEXs hold transformative significance for decentralized finance (DeFi). Grab your MAPO and familiarize yourself with the mechanics of trading on a DEX.
Building a Bitcoin Ecosystem Application or Joinning the Interoperable Bitcoin L2 Network
EVM compatible, no need to learn a new coding language. The Bitcoin Layer 2 network covered by MAP Protocol and other ecosystem public chains are continuously increasing.
What is MAP Protocol?
MAP Protocol serves as a Bitcoin L2 focused on cross-chain interoperability. It provides the essential infrastructure and components for dApps and projects to achieve interoperability between Bitcoin L2s and other popular public blockchains. Built upon ZK light-client technology, MAP Protocol's interoperable cross-chain solution is peer-to-peer, without any trusted third-party entities. Thus, it transforms isolated Bitcoin Layer 2 networks or blockchains using third-party bridges into an integrated and decentralized Bitcoin ecosystem for application development platform and Web3 user gateway.
MAP Protocol as the Layer0 of Bitcoin L2s
Various Bitcoin L2s means isolation of users and assets. The infrastructure provided by MAP Protocol has enabled Bitcoin L2 solutions like Conflux to achieve peer-to-peer connectivity with other Bitcoin L2s and popular blockchains.
At the same time, the interoperability network implemented through ZK-LightClient technology allows Ethereum, BNB Chain, Polygon, Near, Klaytn, etc. including Conflux, to interact with the Bitcoin ecosystem. This makes building seamless and permissionless Bitcoin Layer 2 applications possible.
Don't trust, verify: Refactor light clients verification with ZK-proof
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.
Toward a truly interoperable future: Bitcoin ecosystem and beyond
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 not just EVM ecosystems but also the Bitcoin ecosystem 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 Bitcoin L2 components, enabling the construction of Bitcoin L2 appsand customizable Bitcoin L2 solutions. This provides users with complete control over their data and assets across the whole blockchain ecosystem.
The all-in-one developer portal
MAP Protocol and its ecosystem apps are transparent and open source, making it the go-to solution for all your Bitcoin L2 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 and customize your Bitcoin L2 solutions. Dive into our extensive documentation and tutorials to learn how to combine different components and create an app with groundbreaking features.
