Chainweb
An infinitely scalable PoW blockchain.

Proof of Work (PoW)
Chainweb is a public Proof of Work (PoW) blockchain that improves upon Bitcoin’s design by enabling infinite scaling without compromising security or efficiency. Instead of being a single blockchain like Bitcoin, Chainweb runs several independent blockchains in parallel that communicate with each other.
Enhancing Bitcoin with Chainweb
We strongly believe in the work started with Bitcoin. In fact, our advisor Dr. Stuart Haber is one of the most cited authors in Satoshi Nakamoto’s renowned 2008 Bitcoin whitepaper. But we also believe there’s a great deal of room to improve.
Kadena’s blockchain contains proofs from two previously valid chains. The idea of braiding two chains together for increased security pre-dates Kadena, but we’ve taken the concept several steps further with Chainweb, braiding together more and more Bitcoin-like chains to increase scalability and security.
In 2020, we forked the Kadena network from 10 chains to 20 chains, proving that it's possible to scale Bitcoin PoW to any size. And we’re just getting started. With Chainweb, we could scale to more than 50,000 chains.
Introducing EVM Compatibility
We started with Bitcoin’s secure design and made it smart contract-ready, more scalable, and more affordable. Now, we’re lowering the barrier to adoption even further by adding EVM compatibility to Chainweb.
Developers can write smart contracts in Solidity, leverage existing Ethereum tooling, and deploy established token standards—all while benefiting from Kadena’s scalability, speed, and ultra-low gas fees.

Scaling to Infinity and Beyond
We leverage a Fixed Graph structure called the Peterson Graph. In this system, each chain needs to communicate with 3 peer chains. Once the 3 peer chains communicate with their 3 peers, the entire network is linked in only two communication jumps. The end result? Truly infinite scalability and stronger security — all without compromising the principles of openness, ownerlessness and true decentralization that are necessary for blockchain technology to work at civilization-wide scale.
