Welcome to Kadena

Kadena is the only scalable Layer 1 Proof of Work blockchain — and the only one capable of powering global finance — thanks to our Chainweb technology.

Now on Testnet: Chainweb EVM

Chainweb improved on Bitcoin’s POW foundation, making it smart contract-ready, more scalable and more affordable. With Chainweb EVM, Kadena has become a decentralized alternative to Ethereum Layer 2s, with near-zero gas fees, infinite scalability and energy-efficient POW security.

Secure. Scalable. Decentralized.

Infinitely Scalable

Unlike other platforms, Kadena is designed to power global financial systems, scaling to higher TPS (Transactions Per Second) as more chains are added to the networks.

Beyond Secure

Single-chain Proof of Work networks are impractical to attack; Kadena’s multi-chain network is orders of magnitude harder to attack, growing in difficulty with every chain added.

Unapologetically Proof-of-Work

Our Proof of Work consensus model offers unparalleled security and efficiency that only improves as the network grows.

Energy-Efficient

At present, Kadena transactions use 185,619 times less energy than Bitcoin transactions. And Kadena’s energy efficiency only improves with every chain added to the network.

Easy for Your Team to Build on

Our smart contract language, Pact, is simple to read and write. And developers have access to front- and back-end documentation, example code and more.
