An Open-Source, Public Blockchain Built with Proof of Work

Kadena is a unique open-source, public blockchain. Kadena’s entire architecture, from the blockchain technology to the smart contract language, has been built from the ground up, solving the blockchain trilemma of security, decentralization, and scalability — making it entirely possible for the next generation of the Internet to be built on Kadena!

Here are three reasons why:

Kadena designed Pact to deliver web3 innovation and fundamentals along with web2 usability. As an open-source, Turing-incomplete smart contract language, Pact facilitates transactional logic with a fine-tuned mix of functionality in authorization, data management, and workflow.

Pact ensures smart contracts only execute on a programmer’s intent, thus offering a safer environment for conducting business. Executed directly on ledger, Pact code is stored in a human-readable format as an immutable transaction. Pact contracts can therefore be verified by non-programmers.

Pact is not like JavaScript or Solidity. Microsoft’s VBA, the programming language to create simple Excel formulas, is a better comparison. Pact is a smart contract language accessible to builders of any skill level, whether they are novice JavaScript programmers or computer science PhDs. Developers enjoy peace of mind with next-generation smart contracts built on Kadena with Pact.

Kadena’s Chainweb, the protocol’s native consensus method, becomes increasingly secure and environmentally sustainable as chains deploy, because the amount of mining hash power stays constant. It scales as additional chains are deployed on the Kadena network. As we wrote in the Kadena white paper:

Chainweb is a new parallel-chain Proof-of-Work architecture comprised of braided chains that all mine the same native currency and transfer liquidity between each other. Unlike existing Proof-of-Work architectures, Chainweb offers massive throughput without significantly increasing hash power. Chainweb has the potential to grow to at least 1,250 chains executing upwards of 10,000 transactions per second while still maintaining the unmatched resilience against fraud and censorship of Proof of Work

Chainweb also helps to democratize mining. On Kadena’s multichain proof of work system, individual miners earn mining rewards just as often as they would if they were mining as part of a pool on Bitcoin’s proof of work.

A miner’s reward in a single-chain environment varies. One may only mine a block once per year, which is not sustainable from a profit/loss perspective. In a multi-chain system such as Kadena’s, miners earn several blocks per month.

Mining Kadena is easy — all you need is the hardware. Turn on the machine, put in an address, and point it at a node or a pool to start earning KDA on the only network with truly decentralized proof of work mining.

Block rewards are readjusted against a set schedule every six months. Approximately half of the remaining minable coins are issued as block rewards for 20 years. Kadena is mineable for approximately 120 years.

Pact, Chainweb, and easier mining are just the tip of the iceberg as to what’s ahead for the future of blockchain, thanks to Kadena. Follow us and you’ll learn why!
