Welcome to the Tezos Developer Documentation!

The Project

Tezos is a distributed consensus platform with meta-consensus capability. Tezos not only comes to consensus about the state of its ledger, like Bitcoin or Ethereum. It also attempts to come to consensus about how the protocol and the nodes should adapt and upgrade.

The source code of Tezos is placed under the MIT Open Source License.

The Community

The Networks

Alphanet

Tezos Alphanet is a test network for the Tezos blockchain with a faucet to obtain free tezzies (see Get free Tezzies). It is updated and rebooted rarely and it is either running the same code as beta or the next version that will become beta in a few weeks. It is the reference network for developers wanting to test their software before going to beta and for users who want to familiarize themselves with Tezos before using their real tezzies.

We offer support for Alphanet on IRC.

The Tezos Alpha (test) network has been live and open since February 2017.

Zeronet

Zeronet is the most cutting-edge development network of Tezos. It is restarted without notice, possibly several times a day. This network is mostly used internally by the Tezos developers and may have different constants that Alphanet or Betanet. We offer no support for the Zeronet.

Betanet

The Tezos Beta (experimental) network is the current incarnation of the Tezos blockchain. There is no faucet but real tezzies that have been allocated to the donors of July 2017 ICO (see Activate fundraiser account - Betanet). It is the step before the full Tezos mainnet, with a few caveats.

The Tezos Beta (experimental) network has been live and open since June 30th 2018.
