Promote with Leviathan NewsPolygon CDK now supports Besu as a chain configuration, letting banks launch private QBFT-consensus networks natively connected to Agglayer from genesis. Transfers settle against zero-knowledge proofs on Ethereum rather than multisig bridges, with "pessimistic proofs" blocking any withdrawal exceeding deposits. The deployment runbook is public on GitHub, and CDK Besu is live on Ethereum mainnet. Existing Besu networks can also connect. The Linux Foundation counts 80 institutional platforms on its decentralized trust technologies, including DTCC, Clearstream, Citi Token Services and Project Agorá.
