Overview of Kadena

Why Kadena matters

Vision

Kadena was founded on the idea that blockchain could revolutionize how the world interacts and transacts. But to get to mass adoption, chain technology and the ecosystem connecting it to the business world needed to be reimagined from the ground up. Our founders built a proprietary chain architecture and created the tools to make blockchain work for business – at speed, scale, and energy efficiency previously thought unachievable.

Behind the tech

Prior to the launch of Kadena in 2016, our founders were already leaders in blockchain and crytocurrency solutions:
  • Stuart Popejoy led JPMorgan’s Emerging Blockchain group.
  • Will Martino was recruited from his role as the Tech Lead for the SEC’s Cryptocurrency Steering Committee.
  • Together, Stuart and Will built JPMorgan’s first blockchain, now known as JPM Coin.
Kadena’s advisory team consists of experts such as Dr. Stuart Haber, the co-inventor of blockchain and the most cited author in Satoshi Nakamoto’s renowned 2008 Bitcoin white paper.

Build without compromise with Kadena

Kadena builds technology that makes blockchain work for everyone. Our ecosystem powers real-world use cases for enterprises and entrepreneurs, providing the security of Bitcoin, virtually free gas (transaction fees), unparalleled throughput, as well as Pact – the most secure smart contract language with built-in bug detection.

Complete decentralized infrastructure for builders

Kadena is the only platform offering a complete decentralized infrastructure for builders. Combining a revolutionary chain architecture with the tools needed for widespread adoption, your teams get the full capabilities of blockchain with the ability to go from concept to launch in days vs. months by not having to build from scratch.

Innovation that works

Kadena was founded on the idea that blockchain could revolutionize how the world interacts and transacts. But to get to mass adoption, blockchain technology and the ecosystem connecting it to the business world needed to be reimagined from the ground up. Our founders built a proprietary multi-chain architecture and the tools to make blockchain work for everyone – at speed, scale, and with energy efficiency previously thought unachievable.

Safer smart contracts

Pact makes designing safer smart contracts effortless, whether you’re writing your first contract or launching your fiftieth dApp. It’s fundamentally different from other contract languages. It’s readable by non-developers. It automatically detects bugs, freeing you from the exploits you’ll face on Ethereum and other unsafe platforms. And it has been battle-tested in production applications for over two years.

Write the future on Pact

Pact is the first truly human readable smart contract language. It lets anyone write clearly, directly and safely onto a blockchain—a true advance for automated contracts. Pact automatically detects bugs and keeps the purpose of code clear. With other contract languages, finding bugs and making sense of fine print can be nearly impossible. Pact’s Formal Verification lets you test your contracts to make sure they do what’s intended. Additionally, when you reference code from other contracts, you stay in control of what happens with your transactions, even if they change their code.

Industrial scalability

Unlike other platforms, Kadena is designed to power global financial systems. Our protocol continually scales to higher TPS (Transactions Per Second) as more chains are added to the network. With its revolutionary multi-chain architecture, Kadena is the only scalable layer-1 Proof of Work (PoW) platform capable of scaling to settle the 9+ million trades executed on the NYSE each day.

Proven security

Our founders' experience at JPMorgan revealed the potential for – and limitations of – existing blockchain solutions. In order to solve for the security and throughput demands of financial services clients, Kadena’s protocol runs on the Proof of Work (PoW) consensus mechanism found in Bitcoin, rather than Proof of Stake (PoS). To achieve Kadena’s breakthrough scalability, we braid together multiple Bitcoin-like chains, improving both throughput and scalability while maintaining the security and integrity found in Bitcoin.

Energy efficient at scale

As network demand increases, Kadena’s energy use remains constant. Its unique multi-chain architecture makes it the only platform that can deliver increased energy efficiency as TPS (Transactions Per Second) scales.

No-cost transactions

While we offer marginal transaction fees for consumers, we’ve gone a step further in introducing the first Crypto Gas Stations to allow businesses to eliminate all transaction fees for their customers, thus removing a key barrier to mass adoption of dApps.

The ideal ecosystem

Kadena works with your preferred services, so you can build how you want and where you want. Empowered with our ecosystem of product and service integrations across enterprises, mining, DeFi, oracles, interop, smart contracts, wallets and exchanges, our passionate community of builders, miners, and partners is changing how the world interacts and transacts.
The Kadena ecosystem offers: Scalable, secure blockchain Pact safer smart contracts Gas Stations for no-fee transactions dApp toolkit for rapid development.

Components of the Kadena Platform

Kadena consists of a (layer 1) public chain protocol called Chainweb and a layer 2 protocol called Kuro. The public and layer 2 networks are interoperable through the smart contract language Pact.

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.
n 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.

Resources for interacting with Kadena’s public blockchain are available here.

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.
