Industry-leading speed and safety to deliver the world's biggest ideas.
Prior to founding Kadena in 2016, Stuart Popejoy and Will Martino led JP Morgan's Blockchain Center for Excellence. While at JP Morgan, they built the company's first blockchain called Juno, whose technology has evolved into today's JPM Coin.
During their time at JP Morgan, Stuart and Will vetted the top blockchain projects in an attempt to find the one that could meet the rigorous performance and security requirements of a global financial institution. Ultimately, the search proved that no such blockchain platform existed.
Equipped with this market insight and experience, Stuart and Will created Kadena to answer a range of problems that no one else had addressed. Kadena is the solution needed by both the biggest enterprises and the most innovative entrepreneurs.
Kadena was first used by Fortune 500 companies in 2018 and has continued to expand its portfolio of clients and partners across industries including insurance, healthcare, financial services, supply chain, and government.
As of 2020, Kadena is live with its complete hybrid blockchain platform—a scalable public blockchain, a customizable private blockchain, and the simple & safe smart contract language Pact that connects both networks. Kadena's platform gives the world the tools to take ideas and ambitions to places that none of us have imagined yet.
Among others, Kadena is advised by Stuart Haber, the co-inventor of blockchain and the most cited author in Satoshi Nakamoto's 2008 Bitcoin white paper.
The Kadena Public Blockchain
Kadena's public blockchain is the only sharded and scalable layer-1 PoW network in production today. It utilizes a 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 has braided together multiple Bitcoin-like chains (visualized below).
In 2020, Kadena's public blockchain performed a live network expansion from 10 chains to 20 chains. This doubled throughput, proving the networks's ability to scale in production to meet ever-higher demand.
The Kuro Permissioned Network
Drawing on the team's expertise from working at JP Morgan and the U.S. Securities and Exchange Commission, the Kuro permissioned network was designed to meet the strict requirements and business workflows that secure $100B order books.
Kadena's private blockchain delivers scalability and usability beyond any other private blockchain today. It can scale to thousands of nodes and has been proven to achieve up to 8,000 TPS with latencies below 100ms in real-world testing.
In 2020, the Kuro permissioned network was open-sourced, allowing all developers and users of the Kadena hybrid blockchain platform the capacity to reach up to 480,000 TPS.
The Pact Smart Contract Language
The Pact smart contract language acts as the bridge that ties the Kadena ecosystem together, and it is the most powerful tool for creating applications on a blockchain. Pact is a mature language that was designed to be readable by non-developers and has been battle tested in production applications.
Pact already contains all of the features that other projects say they will develop eventually, including full Formal Verification of user code, error messages, contract upgradability, multi-signature, and support for interoperability. Pact focuses on facilitating transactional logic with the optimal mix of functionality in authorization, data management, and workflow.
Pact is rapidly becoming established as the global standard of smart contract development.
