Stacks Blockchain Networks

Stacks Blockchain Networks

  • Krypton is a Stacks 2 testnet with a fixed, two-minute block time, called regtest. Regtest is generally unstable for regular use, and is reset often. See the regtest documentation for more information on using regtest.

  • Testnet (old Xenon) is the Stacks 2 public testnet, which runs PoX against the Bitcoin testnet. It is the full implementation of the Stacks 2 blockchain, and should be considered a stable testnet for developing Clarity smart contracts. See the testnet documentation for more information on the public testnet.

  • Mainnet is the fully functional Stacks 2 blockchain, see the Stacks overview for information on running a Stacks node, mining, stacking, and writing Clarity smart contracts.
