On a previous post, we described the potential Carthage proposal as well as the Carthagenet Test Network. For the past weeks, Cryptium and Nomadic Labs have not only been updating the carthagenet test network, but also continuously tested, analysed, and refined the potential Carthage proposal. This article aims to inform the Tezos community about the latest updates on the potential Carthage proposal, as well as the plans for the carthagenet test network.

The Updated Carthagenet Test Network

The purpose of the carthagenet test network is to serve as an open and accessible vehicle for core developers, bakers, ecosystem developers, and broader community to thoroughly test not only the potential Carthage proposal’s features, but also the proposal’s transitions from injection until post-activation. The first version of thecarthagenet test network was launched on the 7th of November (see history under “What is the timeline?”).

  1. carthagenet test network was reset on Friday the 29th of November 2019, at ~10 am Paris/Zug time. At the time writing it represents 005, aka current mainnet.
  2. It is currently being operated by willing bakers of the baking Slack group.
  3. Cryptium and Nomadic Labs are planning to inject the hash of the updated potential Carthage proposal into the updated carthagenet test network on Monday, the 9th of December 2019, during afternoon Paris/Zug time.
  4. The updated potential Carthage proposal on the updated carthagenet test network will be subject to a sped up governance process and will be activated on the updated carthagenet test network in 2–3 days*
  5. After the 2–3 days of governance process, the updated carthagenet test network will contain all the new features of the updated potential Carthage proposal.
  6. The updated carthagenet test network will be maintained by and dedicated to developers, bakers, and the broader ecosystem that wishes to test and interact with it. See “How to Interact with the Carthagenet Test Network” below for further information.

*For testing purposes, the governance parameters have been tweaked and the assumption of the protocol successfully passing has been made. However, these parameters and assumption are only valid on the updated carthagenet test network, which is a testnet created for this purpose.

How to Interact with the Updated Carthagenet Test Network

In order to test the updated potential Carthage proposal on the updated carthagenet test network as thoroughly as possible, we encourage bakers, developers, and the rest of the community to actively interact with the testnet.

The updated carthagenet test network is currently operated by willing bakers. In order to simulate real baker participation as much as possible, we encourage bakers to join the updated carthagenet test network following the documentation: http://tezos.gitlab.io/introduction/test_networks.html#carthagenet

At the moment, the most accessible way of interacting with the updated carthagenet test network is via the tezos-client or command line. Find here some documentation on how to install and use tezos-client are applicable to the updated carthagenet test network. When running the commands, make sure you include the flag -A carthagenet.tezos.cryptium.ch, which allows you to interact with one of Cryptium Labs’ synched carthagenet test network full nodes:

$ tezos-client -A carthagenet.tezos.cryptium.ch [...]

In addition to the command line tools, the Tezos community can also interact with the updated carthagenet test network in other ways, such as through transfers or common day-to-day interactions. To do so, you can use many services supporting the updated carthagenet test network:

The Updated Carthage: the Housekeeping Proposal

The Carthage proposal is referred to as a housekeeping proposal as it does not include large features, but rather focuses on code clean-up, adding optimisations, and fixing small issues on the existing protocol version — this is in alignment with the lessons learnt and the goal of soothing the frequency of large scale feature releases. — On the Carthage Proposal and the Carthagenet Test Network

Since the publication of “On the Carthage Proposal and the Carthagenet Test Network” article, Cryptium and Nomadic Labs have continuously worked on testing, analysing, and refining the potential Carthage proposal. In addition to the Gas Limit Increases and the housekeeping features, the updated potential Carthage proposal includes:

  1. An updated rewards function (source), on which Nomadic Labs will publish a detailed article.
  2. Two additional housekeeping features, details of which you can find in the source files (source 1, source 2) and in the updated changelog.

The updated potential Carthage proposal is ready and you can find the source files on this Gitlab branch. By open-sourcing the proposal, the core developers hope to encourage even more community involvement by enabling the community to not only assess the features in advance, but also, if the community wishes to, to inject the proposal on mainnet through their bakers.

Injecting a new proposal is generally straight-forward and any baker, no matter how many rolls, can do it. In order to inject the proposal:

  1. Download the branch with the protocol to a machine with a running mainnet node and the tezos-admin-client installed.
  2. Then run tezos-admin-client inject protocol src/proto_006_PsXXXX/lib_protocol*. Now your node is aware of the new protocol.
  3. The last step is to submit a proposal to the on-chain governance mechanism. In order to do that please run tezos-client submit proposal for <delegate> <PsXXXX>*.

*Remember to replace <PsXXXX> with the canonical hash once it’s been published.
