About
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.
Kadena can scale as required by the needs of its users. However, the main limitation is adoption, as scaling and adding additional blockchains requires the network to undergo a hard fork. In theory, Kadena can scale to 50 or 100 blockchains or even more if it demonstrates continued adoption. The process is not automatic though: once the network becomes congested, fees rise and miners forming a DAO are incentivised to cooperate in reconfiguring the network to a larger size.
How Many Kadena (KDA) Coins Are There in Circulation?
KDA is the blockchain's native token with a total supply of 1 billion KDA. It is used to pay for gas and as a miner reward for producing new blocks. Kadena pre-mined several rounds of KDA. The first private token sale was in 2018 and raised $2.25 million for 4.5 million KDA. The second round raised $12.9 million for 17.2 million KDA. The distribution of KDA looks as follows:
- Mining: 700 million to be emitted over 100+ years
- Platform share: 200 million to be emitted over nine years
- Investors, strategic reserve, and contributors: 90 million
- Burned at launch: 10 million
Currently, 171 million KDA are circulating. The token emissions schedule will decrease gradually over time, and the entire Kadena tokenomics model can be found here.
How Is the Kadena Network Secured?
Kadena uses a chain architecture called Chainweb to combine its several proof-of-work blockchains. Each chain confirms its three peer chains' blocks, thereby increasing throughput linearly with the addition of new chains. This also increases security as Kadena chains achieve a single view of transaction history across chains. An attacker would have to fork not one chain but all the running chains to attack just one.
Kadena's smart contract language is called Pact and is human-readable and Turing-incomplete language specifically built for blockchains with powerful security features.
Where Can You Buy Kadena (KDA)?
KDA is available on Binance, OKX, Mandala Exchange, KuCoin, and Gate.io.

What blockchain does Kadena use? Is it its own blockchain or built on top of another?
Kadena uses its own blockchain, which is distinct and not built on top of another blockchain. It features a unique architecture that combines a public chain (Kadena) with a private chain (Kadena Coda), facilitating scalability and interoperability. Additionally, Kadena employs a consensus mechanism called Chainweb, which utilizes a braided, parallel-chain structure to achieve high throughput and security. This design allows Kadena to process many transactions simultaneously, making it suitable for enterprise-level applications.
Is Kadena programmable? Does it support smart contracts or decentralized applications?
Yes, Kadena is a blockchain platform that is programmable and supports smart contracts and decentralized applications (dApps). It uses a unique smart contract language called Pact, which is designed to be secure and user-friendly, allowing developers to create applications with higher assurance levels.
Kadena's architecture combines a Layer 1 blockchain (the Chainweb) with a Layer 2 solution (Kadena's public and private chains), which enhances scalability and throughput. This design allows for the execution of complex smart contracts and the deployment of dApps, making Kadena a suitable choice for developers looking to build on blockchain technology.
Additionally, it provides tools and features that simplify the development process, making it easier for developers to create and manage smart contracts efficiently.
How fast are Kadena transactions? What is the typical confirmation time and throughput (transactions per second)?
Kadena is known for its high performance and scalability in blockchain technology. As of my last update in October 2023, Kadena claims to achieve throughput of over 480,000 transactions per second (TPS) on its platform, depending on the configuration and the number of chains that are working together.
In terms of confirmation time, Kadena typically offers block confirmations within 10 seconds. This allows for relatively fast finality, enabling quick processing of transactions.
It is important to note that metrics like TPS and confirmation times can vary based on network conditions, the specific use case, and the overall load on the network at any given time. For the most accurate and updated metrics, checking the official Kadena documentation or platform updates is recommended.
How much data can I store on the Kadena blockchain? Does it support on-chain data storage?
Kadena blockchain does not primarily serve as a general-purpose data storage platform like some other blockchains might. Instead, it is designed to facilitate fast and secure transactions, particularly for enterprise-level applications. While you can store some data on-chain, the focus is more on maintaining the integrity and security of the transaction history rather than serving as a large data repository.
Kadena uses its unique Chainweb architecture, which allows for multiple parallel chains, thereby improving scalability and throughput. You can store small amounts of data associated with transactions, but it's recommended to limit data storage to essential information to ensure network efficiency.
For more extensive data storage needs, it's common to pair blockchain technologies with off-chain solutions, such as decentralized file storage systems (e.g., IPFS or Filecoin), where large datasets can be stored more economically while keeping essential transaction-related data securely on-chain.
If you are considering using Kadena for a specific application, it's best to assess your data storage needs and design your solution accordingly, possibly combining on-chain and off-chain storage methods.
