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


The Tezos network is the current incarnation of the Tezos blockchain. It runs with real tez that have been allocated to the donors of July 2017 ICO (see Activate fundraiser account - Mainnet).

The Tezos network has been live and open since June 30th 2018.

All the instructions in this documentation are valid for Mainnet however we strongly encourage users to first try all the introduction tutorials on some test network to familiarize themselves without risks.

Test Networks

There are several test networks for the Tezos blockchain with a faucet to obtain free tez (see Get Free Tez). 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 tez.

See the list of test networks in test network.
