Innovation that

Behind the tech

Kadena was founded on the idea that blockchain could revolutionize how the world interacts and transacts. But to get to mass adoption, chain technology and the ecosystem connecting it to the business world needed to be reimagined from the ground up. Our founders built a proprietary chain architecture and created the tools to make blockchain work for business – at speed, scale, and energy efficiency previously thought unachievable.

Our founders

Prior to the launch of Kadena in 2016, our founders were already leaders in blockchain and cryptocurrency solutions:

Our advisors

Kadena’s advisory team consists of experts such as Dr. Stuart Haber, the co-inventor of blockchain and the most cited author in Satoshi Nakamoto’s renowned 2008 Bitcoin white paper.

Haber’s innovations don’t end with Bitcoin but live on in Kadena with the launch of Immutable Records (IR) on our upcoming NFT platform. Founded alongside the other co-investor of blockchain, W. Scott Stornetta, IR exploits Kadena’s unique advantages, such as institutional-grade provenance, on-chain minting and custom marketplaces.

Public blockchain reimagined


Kadena's public blockchain, Chainweb, is the only sharded and scalable layer-1 PoW network in production today. It utilizes a PoW (Proof of Work) consensus mechanism that improves throughput and scalability while maintaining the security and integrity found in Bitcoin. To achieve this breakthrough in scalability, Kadena braids together multiple Bitcoin-like chains.


In 2020, Kadena's public blockchain performed a live network expansion from 10 chains to 20 chains. Doubling the available TPS, the expansion proved the platform’s ability to scale in production to meet ever-higher demand. Kadena’s multi-chain architecture ensures that a throughput ceiling will never be reached.

No competition

The two highest valued settlement platforms, Ethereum and Bitcoin, rely on the proven PoW consensus protocol for security. And therein lies the challenge: traditional PoW is not scalable. With its revolutionary, braided multi-chain architecture, Kadena is the only scalable PoW platform capable of scaling to settle the 9+ million trades executed on the NYSE each day.


Kadena's tokenomics align the incentives of all participants. The main allocation of coins is distributed through mining. Coins from allocations (investors, contributors, and the platform reserve) become available gradually, creating stability. The network and token schedules are designed for sustainability, with an adoption curve to ensure that the economy will scale instead of spiking.

Smarter, safer contracts


Pact is the most powerful smart contract language available for writing applications directly on the blockchain. Pact was designed to be readable by non-developers and has been battle tested in production applications for over two years.

Ahead of the curve

Pact already contains all the features that other projects say they will eventually develop, including full Formal Verification of code, error messaging, contract upgradability, multi-sign, and support for interoperability. Pact facilitates transactional logic with an ideal combination of functionality in authorization, data management, and workflow.
