What Is Kadena (KDA)?

Kadena is a proof-of-work blockchain that combines the PoW consensus mechanism from Bitcoin with directed acyclic graph (DAG) principles to offer a scalable version of Bitcoin. Kadena claims it can provide the security of Bitcoin while being able to offer unparalleled throughput that makes the blockchain usable to enterprises and entrepreneurs alike. Kadena's unique infrastructure is decentralized and built for mass adoption because of its multi-chain approach.

Kadena promises industrial scalability that can support global financial systems and can be scaled as necessary. It also vows to remain energy-efficient at scale and deliver more transactions with the same energy input, another difference to Bitcoin. Moreover, Kadena offers crypto gas stations, which allow businesses to pay for their customers' gas fees and remove a massive pain point in adopting blockchains for business.

Kadena has already scaled its network from 10 to 20 blockchains and can do so again in the future, if necessary.

Who Are the Founders of Kadena?

Kadena was founded in 2016 by Stuart Popejoy and Will Martino. Stuart Popejoy led JPMorgan's Emerging Blockchain group before founding Kadena and has 15 years of experience building trading systems and infrastructure in finance. Will Martino was the Lead Engineer for JPMorgan's blockchain prototype Juno and led the Securities and Exchange Committee's Cryptocurrency Steering Committee and Qualitative Analytics Unit. Another key persona in founding Kadena was Dr. Stuart Haber, who is the co-inventor of blockchain technology and the most cited author in the Bitcoin whitepaper.

Furthermore, Kadena raised capital from a number of crypto venture capitalists like Multicoin Capital, CoinFund, Amino Capital, and others.

What Makes Kadena Unique?

Kadena offers a public proof-of-work blockchain with unparalleled throughput by combining two separate consensus mechanisms: DAG and proof-of-work.

In simple terms, Kadena achieves this by braiding chains together, meaning it offers not one but several (20) separate blockchains that all work simultaneously and asynchronously to validate transactions. This allows Kadena to mint multiple blocks simultaneously, thus increasing its throughput. This also increases security by reducing an attacker's time between block confirmations.

Kadena uses a directed acyclic graph structure to scale from one proof-of-work blockchain to theoretically an unlimited amount. However, its DAG structure is fixed and multi-channel, meaning Kadena's blockchains only communicate with three peer chains instead of randomly confirming transactions. This improves real-world performance and scalability.
