Chainweb is Kadena’s braided, parallel-chain proof-of-work architecture that runs multiple chains simultaneously and links them with cross-chain uncle proofs, enabling parallel transactions while maintaining proof-of-work security.

Quotes that support claims

At its core, Kadena implements Chainweb, a braided, parallel-chain architecture that runs many chains concurrently while interlinking them via cross-chain uncle‑proofs.

The current iteration of the testnet consists of five independent Ethereum Virtual Machine (EVM) chains operating simultaneously under Kadena’s Chainweb consensus framework. Each chain benefits from merge-mined security comparable to that of Bitcoin while supporting native interoperability for cross-chain communication.

Built on Kadena’s braided proof-of-work architecture, Chainweb EVM executes transactions in parallel across multiple chains, boosting throughput while preserving the security guarantees of proof-of-work.
