What is Kadena (KDA)?

Blockchain technology has the power to reshape modern systems with its ability to enable decentralized, trust-free applications. From automated smart contracts to digital representations of physical assets, the possibilities of blockchain are still in their early stages of exploration. However, if you’ve ever tried to build a blockchain application — such as a decentralized exchange (DEX) — you’ve likely faced significant challenges that could make the process feel insurmountable.

Organizations and individuals looking to integrate blockchain into their operations often run into common obstacles. These include poor interoperability, meaning blockchains struggle to exchange information seamlessly, and scalability issues, where handling high volumes of transactions becomes a bottleneck. Additionally, creating and deploying smart contracts can be risky, complicated, and costly, with errors leading to vulnerabilities.

Kadena aims to change this reality. As a hybrid blockchain designed for enterprise use, Kadena provides developers with a new smart contract language and advanced development tools. The goal is to deliver a blockchain solution that is interoperable, scalable, and energy-efficient. Let’s explore Kadena’s approach, features, ecosystem, and its native token, KDA.

How does Kadena Work?

Kadena is a Layer 1 blockchain that uses a Proof-of-Work (PoW) mechanism to achieve high scalability while maintaining robust security, similar to Bitcoin. Kadena’s unique architecture combines the Chainweb consensus protocol with the Pact programming language to create a system optimized for both developers and enterprises.

Unlike systems that rely on Layer 2 protocols to enhance scalability, Kadena focuses on improving its foundational infrastructure. This simplifies application development by offering an all-in-one platform. According to Kadena’s team, the blockchain can handle up to 480,000 transactions per second across 20 parallel chains. Future expansions to 50 chains could push that limit to over a million transactions per second.

Pact, Kadena’s programming language, addresses key weaknesses in Ethereum’s Solidity. Specifically, Pact reduces risks associated with unbounded loops and supports Formal Verification — a mathematical method to ensure that code behaves as intended. Additionally, Pact allows developers to upgrade smart contracts without requiring disruptive hard forks, making maintenance and updates far easier.

Kadena also offers a private blockchain, Kadena Kuro, which is tailored for enterprise applications. Kuro employs a Byzantine Fault Tolerant (BFT) consensus mechanism to provide a secure and efficient environment for business use. Since 2018, a healthcare consortium has utilized Kuro to improve the management of insurance data. Acting as a side-chain to Kadena’s public blockchain, Kuro enhances the system’s overall capacity and enables innovative data-driven solutions.

Kadena’s focus on scalability, security, and developer-friendliness positions it as a promising option for building and scaling blockchain-based applications without the traditional hurdles.

Who Founded Kadena?

Kadena was established by Stuart Popejoy and Will Martino. The blockchain is developed and overseen by Kadena Inc., a team of over 20 professionals primarily focused on blockchain technology. Both founders previously worked on J.P. Morgan’s blockchain team, gaining experience in one of the largest U.S. banks, which has been actively exploring blockchain and cryptocurrency technologies in recent years.

What is Chainweb?

The foundation of Kadena’s blockchain ecosystem is Chainweb, its Layer 1 network. Chainweb operates using the Proof-of-Work (PoW) consensus mechanism, the same approach that powers Bitcoin. This system is well-known for its security but also for its high energy requirements and limited scalability. However, Kadena’s implementation overcomes some of these drawbacks through an innovative design.

Chainweb consists of multiple independent mining chains running in parallel, enabling the network to handle a large number of transactions simultaneously. This structure eliminates the need for additional Layer 2 solutions to achieve scalability. The network remains secure because every block undergoes double validation, which ensures that duplicate transactions cannot occur. Despite this rigorous security measure, the system maintains speed, producing a new block approximately every 1.5 seconds.

What is Kuro?

In addition to Chainweb, Kadena offers a Layer 2 blockchain called Kuro. Kuro is a private network that supports the development of public smart contracts. It employs the Byzantine Fault Tolerance (BFT) consensus mechanism, which is optimized for scalability, ensuring the network can handle high transaction volumes efficiently.

Kuro allows developers to build decentralized applications (dApps) using Pact, a programming language specifically created by Kadena. Pact addresses many of the security concerns associated with Ethereum’s Solidity, such as vulnerabilities in smart contracts. Additionally, Pact makes it easier for developers to update contracts without requiring disruptive network hard forks.

The performance capabilities of Kuro are impressive, supporting up to half a million transactions per second. For comparison, Ethereum processes just 15 to 45 transactions per second, demonstrating Kuro’s scalability and cost-efficiency. Developers can build on Kuro without worrying about long delays or excessive fees, making it a practical choice for creating scalable applications.

What is Pact?

Pact is the foundational programming language of Kadena’s blockchain, offering built-in bug detection to enhance security. It is the first human-readable and Turing-incomplete smart contract language, designed to make blockchain app development accessible to both technical and non-technical users. Pact’s straightforward and secure design simplifies app creation without compromising functionality.

The language was created to address the challenges faced by existing blockchain programming tools like Ethereum’s Solidity. Solidity, being Turing-complete, is capable of performing any computational task, but this flexibility introduces vulnerabilities such as unbounded loops. In contrast, Pact’s Turing-incompleteness prevents these issues by rejecting recursive processes outright, eliminating a common vector for attacks.

A notable feature of Pact is its ability to grant developers control over their smart contracts even after upgrades. By referencing code from existing Pact contracts, users can ensure secure and predictable behavior for their transactions. For example, the infamous 2016 DAO attack on Ethereum exploited a reentrancy vulnerability inherent in Turing-complete code—a problem that Pact’s structure avoids entirely.

Kadena’s Core Features

Kadena’s ecosystem is designed to overcome the challenges of scalability, security, and user accessibility that have hindered widespread blockchain adoption. Its innovative solutions provide the foundation for building robust Web3 applications.

Scalability

Kadena achieves scalability through sharding, a process where the network splits into smaller parts, or shards, each handling a subset of transactions. This approach allows shards to process transactions and create blocks simultaneously, significantly boosting throughput. As the number of shards increases, so does the network’s capacity, enabling Kadena to handle growing demand efficiently.

Security

Kadena secures its network using a braiding technique, where each block contains hashes of both its previous block and blocks from other chains in the network. This cross-referencing ensures that blocks validate one another, regardless of which shard or chain they belong to. To compromise the system, an attacker would need to control over 51% of the network’s hash power, rather than focusing on individual shards, making attacks much harder to execute.

While braiding introduces complexity, Kadena’s Chainweb system uses concepts like degrees and diameters to simplify the process for all users, whether they are developers or not.

Formal Verification (FV)

Pact includes a Formal Verification (FV) tool, allowing developers to mathematically verify their code for errors or unintended behavior. Think of FV as a debugging tool for smart contracts, akin to a grammar-checking software for programming. FV not only detects vulnerabilities but also confirms whether the contract will behave as intended under all conditions, enhancing overall reliability.

Blockchain Governance

Governance in Pact is streamlined, enabling updates or fixes to smart contracts without requiring disruptive changes like hard forks. If an abnormality is detected in a smart contract, it automatically reverts to its previous state, rejecting any further problematic changes. This ensures a stable, adaptable system where users can trust the integrity of their contracts.

By addressing scalability, security, and governance, Kadena’s network and the Pact language provide the tools needed for building efficient and secure blockchain applications.

Kadena’s KDA Token

KDA serves as the utility token within Kadena’s ecosystem, functioning as a payment method for network activities. Users primarily use it to cover transaction fees, but it also plays a role in incentivizing miners who support the network.

Mining Kadena contributes to the network’s security by verifying transactions. Once verified, these transactions are grouped into blocks and added to the blockchain. Miners are rewarded with KDA tokens, which are generated from the transaction fees paid by users.

Beyond its functional purpose, KDA can also be viewed as an investment opportunity. Those who believe in Kadena’s long-term potential may choose to buy KDA tokens, anticipating a future increase in value. However, before making such decisions, it’s essential to thoroughly research the project and understand the risks involved.

KDA is listed on several major cryptocurrency exchanges, including OKX, Gate.io, and Coinbase, making it easily accessible to users who wish to trade or invest in the token.
