Kadena

Kadena is a blockchain technology company established in 2016 by Stuart Popejoy and Will Martino. The founders brought extensive experience from the financial and regulatory sectors to address the blockchain trilemma of achieving concurrent scalability, security, and decentralization. Popejoy previously led JPMorgan's Emerging Blockchain group, while Martino was the Lead Engineer for JPMorgan's blockchain prototype, Juno, and also served as the Tech Lead for the SEC's Cryptocurrency Steering Committee. Their collective background at the intersection of high-finance trading systems and regulatory frameworks shaped Kadena's mission to build a blockchain suitable for enterprise and business applications.

The company operates a hybrid blockchain platform that includes a public layer-1 Proof-of-Work (PoW) network called Chainweb and a private blockchain, formerly known as Kuro, designed for commercial use. Kadena's business model centers on providing the infrastructure for developers and enterprises to build and deploy decentralized applications. Revenue generation is tied to the utility of its native token, KDA, which is used to pay for computational services and transaction fees on the network, similar to how ETH functions on Ethereum. The company also fosters ecosystem growth through grants and strategic partnerships.

Kadena's core product is its unique multi-chain architecture, Chainweb, which braids multiple parallel blockchains together. This design leverages PoW for security, akin to Bitcoin, while enabling high throughput by processing transactions in parallel across its chains, which started at 10 and has since scaled to 20. This architecture is engineered to be scalable; as demand increases, more chains can be added to the network to boost transaction capacity. A key differentiator is the proprietary smart contract language, Pact. Pact is designed to be human-readable, which simplifies security verification, and it allows for upgradeable smart contracts, giving developers the flexibility to adapt their code over time. To improve user adoption for businesses, Kadena introduced crypto gas stations, which enable businesses to cover transaction fees for their customers, removing a common friction point.
