Kadena

Kadena is creating a public blockchain using a new consensus mechanism called Chainweb, which uses a graph theory based braided Proof of Work system. The are also building an enterprise blockchain using BFT-consensus protocol.

Metastable, Kilowatt Capital, Coinfund and Multicoin Capital all invested in blockchain startup Kadena in a $2.25 million in a pre-A financing private-placement SAFT in January 2018.

Kadena has raised $12 million from Devonshire Investors, Fidelity Investments, SIG, Asimov Investments, Multicoin Capital and SV Angel and others through a Simple Agreement for Future Tokens (SAFT) sale.

Kadena's Chainweb proof of work consensus system is intended to combine many parallel peer blockchains which can integrate their merkle roots together, ensuring that they can share information across the chains and create consensus across ledgers.

According to co-founder Stuart Popejoy, Kadena is building tools for the broader community to test, including a formal verification toolkit to help identify bugs. Kadena demonstrated a working prototype of the formal verification tool in 2017.
