Replacing Multi-Sig Bridges with Mathematical Cryptography
**Union**, the modular zero-knowledge interoperability layer connecting disparate blockchain ecosystems, has officially surpassed **500,000 verified cross-chain consensus proofs** on its public testnet. Backed by **$4 Million** in seed funding from **Galileo**, **Semantic Ventures**, and **Tioga Capital**, Union represents a critical architectural upgrade for cross-chain communications.
Over $2.8 Billion has been lost in bridge exploits throughout crypto history due to vulnerable multi-signature committees and compromised validator keys. Union eliminates trusted intermediaries by verifying source chain consensus directly within zero-knowledge cryptographic light clients.
Core Advantages of Union Interoperability
* **BLS Consensus Proofs**: Verifies state transitions mathematically rather than relying on human committee attestations. * **Cosmos IBC to EVM Rollups**: Natively connects Cosmos chains to Ethereum Layer 1, Arbitrum, and OP Stack rollups. * **Sub-Second Proof Generation**: Succinct proofs verify on-chain for mere fractions of a cent in gas.
As modular ecosystems expand across hundreds of independent chains, Union's trustless verification infrastructure is setting the security benchmark for Web3 interoperability.
