UPDATE 6/3/2019: Our Miner Whitelist is now LIVE! Apply by filling out our 10-question application.

The Kadena team is excited to announce that our scalable Proof of Work public blockchain will be launching mainnet on October 30, 2019! We also have updates from our testnet, including an upcoming whitelist queue for miners to participate in our testnet.


Mainnet is significant because Kadena is launching the first scalable and secure Proof of Work blockchain. Kadena Public 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.

After a successful launch of 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. NOTE: This is NOT pre-mining of the public blockchain. Miners will get to learn how our public blockchain works and collaborate with our team to scale the network. Be part of making history with the first scalable PoW blockchain!

If you do not get selected as a v1 miner, please be patient. We are working hard to make Testnet v2 fully public, allowing anyone to participate and test-mine the network.

Below are noted updates to the functionality of 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
  5. Coin faucet
  6. Cross-chain transfer via Pact SPV
