Kadena consists of two main components which are a public chain protocol or layer-1 called Chainweb and a layer-2 called Kuro. Chainweb tackles the problem of low throughput faced by bitcoin by using a braided, parallel proof-of-work consensus mechanism. This help the network scale when more nodes join in. Kuro on the other hand have been proven to be able to handle 8000 transactions per second across 500 nodes. Kadena is built upon Pact, a smart contract that is purpose-built for blockchain and has powerful security features including automatically detecting bugs. Kadena is different from other blockchain in that it is built upon 20 multi-chain that work together in parallel rather than a single blockchain. Such architecture allows Kadena blockchain to achieve 480,000 transactions per second.

Kadena Token (KDA) plays similar role to ETH on Ethereum network. KDA is used to incentivise miners who continue to mine new blocks and maintain the network. It is also used as transaction fees when users transact across the network. The total supply of KDA is 1 billion tokens to be mined over 120-year period.
