1. Chainweb, Kadena’s (layer 1) 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.
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.

2. 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.

3. Kuro, Kadena’s layer 2 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.

4. Kadena's layer 1 + 2

HEADLINE: With 20 chains, the Kadena blockchain platform achieves an industry-leading 480,000 transactions per second.
Chainweb nodes have their own “local cluster” of two independent Kuro chains. They synchronize with the Chainweb node using a cross-chain bridge. Kuro chains in the cluster can accept transactions at 8k per second directly from clients and between each other. Thus a single cluster can do 16k TPS. Using the power of both layer 1 and layer 2 networks, Kadena’s blockchain can achieve around 480,000 TPS.
