Welcome to the Dune Developer Documentation!¶
The Project¶
Dune is a distributed consensus platform with meta-consensus capability. Dune 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.
- Developer documentation is available online at https://dune.network/docs/dune-node-mainnet . Make sure you are consulting the right version.
- The website https://dune.network/ contains more information about the project.
- All development happens on GitLab at https://gitlab.com/dune-network
The source code of Dune is placed under the GPLv3 License.
The Community¶
The website of the Dune Foundation.
Dune sub-reddit is an important meeting point of the community.
Several community-built block explorers are available:
More resources can be found on https://docs.dune.network
The Networks¶
Mainnet¶
The Dune network is the current incarnation of the Dune blockchain.
It runs with real DUNs from several sources:
- Foundators of Dune received tokens on June 24, 2019
- Tezos users received tokens through an airdrop in September 2019
- Tezos ICO participants can claim DUNs equivalent to their Tezos allocation (see Activate ICO account - Mainnet).
The Dune network has been live and open since June 24th, 2019.
All the instructions in this documentation are valid for Mainnet however we strongly encourage users to first try all the introduction tutorials on Testnet to familiarize themselves without risks.
Testnet¶
Dune Testnet is a test network for the Dune blockchain with a faucet to obtain free DUNs (see Get free DUNs). It is updated and rebooted rarely and it is running the same code as the Mainnet. 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 Dune before using their real DUNs.
We offer support for Testnet on IRC.
