Polyhedra Network: Building the Largest Interoperable Bitcoin Ecosystem with zkBridge

Bitcoin ecosystem is currently experiencing rapid expansion since the emergence of the Ordinals protocol. To foster further growth, there is a pressing need for a solution that not only enables seamless interactions across Bitcoin, Bitcoin Layer-2s, Ethereum, and Ethereum Layer-2s.
Addressing this need for interoperability, Polyhedra Network introduced the Bitcoin Messaging Protocol powered by zkBridge, the interoperability protocol designed and implemented by Polyhedra Network. This pioneering development expands Bitcoin's functionality, enabling it to interact seamlessly with a range of blockchain networks, both Layer-1s and Layer-2s.

Using zkBridge, Bitcoin can now securely transmit its current and historical data, utilizing zero-knowledge proofs, to 20+ networks including Bitcoin Layer-2s, Ethereum, and Ethereum Layer-2s. This interoperability extends to recent Bitcoin innovations such as Ordinals, BRC-20, and Atomicals. To enable other blockchains to securely write messages to Bitcoin, the protocol employs a Proof-of-Stake mechanism with a carefully designed slashing mechanism, to overcome Bitcoin’s lack of smart contract functionality.

Polyhedra Network has joined forces with key builders within the Bitcoin ecosystem across infrastructures, wallets, Bitcoin layer-2s, DeFi, and tools. Together, they are introducing the largest Interoperable Bitcoin Ecosystem empowered by zkBridge. Partners of the largest interoperable Bitcoin ecosystem includes:
OKX Wallet: One-stop web3 entrance for Bitcoin ecosystem.
UniSat Wallet: an open-source Chrome extension for Bitcoin ordinals & BRC-20 assets.
EigenLayer: A platform that helps decentralized networks launch with robust trust by leveraging Ethereum stakers & validators.
