In a fragmented blockchain landscape, seamless and secure communication across networks is no longer optional—it’s foundational. Polyhedra Network delivers this through its cutting-edge zero-knowledge proof (ZKP) technology, making interoperability, scalability, and real-world asset integration not just possible, but efficient.

What is Polyhedra Network?

Founded by Tiancheng Xie and James Zhang, Polyhedra Network is a ZK-native infrastructure protocol pushing the boundaries of Web3 by bridging blockchains and integrating with Web2. Its flagship innovation, zkBridge, allows for trustless, verifiable, and efficient cross-chain communication.

The zkBridge protocol also serves as a proving ground for Gemini, Polyhedra’s lightning-fast ZK proof system that runs on specialized hardware. By embedding cryptographic assurances into message passing, asset transfers, and more, zkBridge is solving one of Web3’s biggest technical hurdles: secure interoperability.

Core Technologies

  • zkBridge: Facilitates trustless cross-chain communication across 20+ L1 and L2 networks.

  • Gemini & Expander: Ultra-fast zero-knowledge proof systems for efficient and private validation.

  • Proof Cloud: Scalable infrastructure enabling decentralized proof generation at scale.

  • Partnerships: Integrations with Google Cloud, AltLayer, and Nubit for enterprise-grade deployment and decentralization.

Real-World Applications

Polyhedra supports developers building:

  • Cross-chain DeFi protocols

  • NFT and data transfers across chains

  • Secure Web2–Web3 integrations

  • Real-world asset onboarding into Web3

This makes ZKJ not just a token, but an essential backbone for the next-gen internet.

Key Milestones

  • 2022: Launch of zkBridge

  • 2023: Release of Gemini prover and Proof Cloud

  • 2023: $20M strategic funding; partnerships with AltLayer and Nubit

  • 2023: $ZK staking launched; ticker rebranded to $ZKJ

  • 2024: zkBridge expands to support 20+ networks and Web2 applications

Conclusion

Polyhedra Network is not just another ZK project—it’s a foundational layer for a trustless, cross-chain internet. With a strong team, real technology in production, and significant traction across Web3 infrastructure, ZKJ is positioned at the heart of blockchain’s most critical evolution: interoperability with privacy.

Unity Wallet supports ZKJ on the Ethereum and Binance Smart Chain blockchains. Unity users are presently able to send, receive and swap ZKJ.
