Kadena,  a blockchain platform for businesses and enterprises founded by the same lead engineers who started JP Morgan’s blockchain capabilities, today announced that its scalable Proof of Work public blockchain, Chainweb, will be launching its mainnet on October 30, 2019. The team also provided updates from its testnet, including an upcoming whitelist for miners to participate in.

Chainweb mainnet is significant because Kadena is launching the first scalable and secure Proof of Work blockchain. Chainweb mainnet will launch with a braided, mining-powered, multi-chain environment capable of higher transaction speeds and greater security than existing systems like Bitcoin and Ethereum.

Testnet v1 Miner Whitelist:  May 30, 2019

“After a successful launch of Chainweb Testnet v0 in March, we are making substantial updates to push towards v1. Of special interest to our community, we will begin accepting applications and approve select external miners into our test network. We’ve already seen interest with signups to our mining waitlist, and on May 30, we will open up our testnet with a whitelist queue.”

The Kadena Team

Those interested in testnet mining can now signup. If selected as a v1 miner, the role will be to help Kadena run nodes as well as test the functionality, syncing and consensus of Chainweb. The Kadena team noted that this is not pre-mining of the public blockchain. Miners will get to learn how Chainweb works and collaborate with the team to scale the network.

Below are noted target updates to the functionality of Chainweb Testnet v1:

  1. Fast node restart without having to re-sync old data
  2. Memory-stable execution (persistence)
  3. Bounce network to 20-chain configuration
  4. Contract store for pact.kadena.io (Pact is Kadena’s human-readable smart contract language.)
  5. Coin faucet
  6. Cross-chain transfer via Pact SPV
