The Tezos blockchain
--------------------

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.

`Tezos.com <https://tezos.com/>`_ contains more information on Tezos overall.

Octez is an implementation of Tezos software, including a node, a client, a baker, an accuser, and other tools, distributed with the Tezos economic protocols of Mainnet for convenience.
This implementation is available at https://gitlab.com/tezos/tezos.

Mainnet
~~~~~~~

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 fundraiser (see :ref:`activate_fundraiser_account`).

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 :ref:`test network <test-networks>` to familiarize themselves without
risks.

Test Networks
~~~~~~~~~~~~~

There are several test networks for the Tezos blockchain with a
faucet to obtain free tez (see :ref:`faucet`).
These networks are intended 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 :ref:`test network <test-networks>`.
