What is Kadena?

Why Kadena Matters

The purpose of Kadena is to be a single source for the resources needed to build blockchain applications. In doing so, Kadena solves many of the problems that have impeded widespread blockchain adoption to date including scalability, security, and ease-of-use.

1. Scalability

The public blockchain is a Proof of Work protocol that has solved layer-1 scalability. This is achieved by braiding together several Bitcoin-like chains. As transaction volume increases, the network can expand to larger configurations (eg. from 10 chains to 20 chains) and deliver higher throughput capacity.

2. Security

The smart contract language, Pact, is Turing Incomplete and offers Formal Verification. Turing Incompleteness reduces the language’s attack surface without compromising domain-specific functionality. Formal Verification allows smart contract authors to mathematically prove that their code does not contain bugs.

3. Ease-of-use

Kadena was developed in part to be integrated into traditional business workflows and understood by non-technical users. Accordingly, Pact code is executed directly on the ledger and is stored in a human-readable format. Pact code has error messages and Pact contracts are upgradable allowing developers to fix errors or adapt logic as business needs evolve.

Kadena is among the first blockchain projects to deliver such a comprehensive feature-set.

Further, users are able to enjoy these features across Kadena’s hybrid blockchain platform, a public-private interoperable network. This hybrid solution allows users to take advantage of the benefits from both public and private blockchains without compromise, thus enabling use cases that were previously not possible.

Components of the Kadena Platform

Kadena is a hybrid blockchain platform consisting of a public chain protocol called Chainweb and a private chain protocol called Kuro. The public and private networks are interoperable through the smart contract language Pact.

1. Chainweb, Kadena’s public blockchain protocol

HEADLINE: Chainweb is a braided, parallelized proof-of-work consensus mechanism that improves throughput and scalability while maintaining the security and integrity found in Bitcoin.

Informational Resources

Resources for interacting with Kadena’s public blockchain are available at the Public chain interaction page.

2. Kuro, Kadena’s private blockchain

HEADLINE: Kuro has been proven to support up to 8,000 transactions per second across 500 nodes, and is available for evaluation on AWS and Azure.

Informational Resources

Resources for deploying Kuro are available at the Private chain deployment page.

3. Pact, Kadena’s smart contract language

HEADLINE: Pact is a human readable and Turing Incomplete smart contract language purpose-built for blockchains with powerful security features including full Formal Verification of user code, error messages, contract upgradability, support for interoperability, and strong permission and access control.

Informational Resources

Resources for using Pact are available at the Public chain interaction page.

Hybrid Blockchain

HEADLINE: Kadena’s hybrid blockchain allows users to interact between public and private networks, gaining the decentralization of public and the security controls of private, to make a more secure digital marketplace.
