In an exclusive interview, Karel Kubat, co-founder of Union, shares insights into the project's infrastructure and its role in enhancing blockchain network interoperability. The discussion covers the technology's features, inspirations behind creating Union, and future plans.

What is Union?

Union is an infrastructure project aimed at reducing fragmentation across blockchain networks. It provides sovereign, fully permissionless interoperability by leveraging Zero-Knowledge Proofs (ZKP) to enhance connectivity among appchains, L1s, and L2s without relying on trusted third parties.

A Unique Approach

Union addresses the sovereign bridging trilemma by establishing a decentralized, permissionless interoperability layer that connects blockchain networks without intermediaries. The use of ZK technology enhances security and decentralization, removing central points of failure. Union employs the unique Boneh–Lynn–Shacham (BLS) method for signature aggregation, ensuring not only reliability but also resource efficiency.

Future Prospects and Strategic Plans

Union aims to be the leading interoperability solution in the blockchain space, focusing on decentralization and integrating diverse ecosystems like Ethereum, Polygon, and Cosmos. Partnerships, such as with Native, address vulnerabilities in existing bridge solutions, aiming for sustainable integration.

Karel Kubat envisions Union becoming a pivotal player in decentralization, helping unlock liquidity flows and expanding decentralized finance capabilities.
