Test network gamma · v0.3.0-gamma.1

An experimental proof-of-work coin, built to learn how these systems work.

A GPU proof of work (matmulhash v2) and Monero's newest privacy design, FCMP++ and Carrot, from the first block. Written in Rust, by one person.

This is a learning project, not a currency

Nothing on any Tenero network has any value, and the test network can be reset.
It is unaudited. The privacy code is unaudited as used here: Monero's FCMP++ libraries (only partly audited), a Carrot written in Rust by this project, and message signatures and payment proofs that are this project's own construction, reviewed by nobody.
The proof of work is new, unreviewed, and not claimed to be ASIC-proof.
Do not use any of it to hold anything you cannot afford to lose.

Inspired by Monero's design ideas; not affiliated with or endorsed by the Monero project.

How it works

The chain

A block every 60 seconds, aimed for. The difficulty is re-worked every block from the last 30 (LWMA), and a block's time must be later than its parent's.

Coins

Ticker TNR. 20 coins a block at first, halving every 525,600 blocks (a year), up to 20,000,000, then a tail of 0.5 a block. No premine: every coin is mined, the author's included.

Proof of work

Each attempt multiplies a 64 × 8192 matrix of 8-bit integers against columns gathered from a 4 GiB dataset, rebuilt every 100 blocks. The aim is to be limited by memory bandwidth, which GPUs are built for. That is an argument, not a proof.

Privacy

A spend proves with FCMP++ that its coin is one of all outputs on the chain; amounts are hidden with Bulletproofs+. Addresses are Carrot (start with TENg), with subaddresses and view-only wallets. On a young chain a spend hides among very few outputs.

Measured on one RTX 5070 Ti: about 45,000 attempts a second. On a CPU, mining gamma is impractical. Everything else is in the consensus rules, the known issues and the threat model.

Get started

Download only from the GitHub Releases page (a Windows zip and a Linux tar.gz), and check the SHA-256 against SHA256SUMS. Or build it yourself with Rust. Read the release notes first.
Run the wallet app, tenero-wallet-gui. It starts the node and the miner itself. The node needs about 4.3 GiB of free RAM.
Mine on an NVIDIA GPU (RTX 30 series or newer, a driver for CUDA 13), alone or in the test pool.

Your antivirus may call it a "coin miner". That is partly true: it includes a miner, which runs only when you start it. The files are not code-signed. Check the hash, or build from source.

Seeds (built in)

195.26.244.245:38353
194.238.27.60:38353

Two computers, one person. You can add your own with --seed ip:port.

Test pool (built in)

195.26.244.245:38335

PPLNS, no fee, pays hourly at 0.1 coins owed. A pool keeps the block rewards and pays by its own rules; nothing makes it pay. One computer, one person.

Talk and notices

Questions, bug reports and hardware numbers: the Discord server. Nothing said there is an official notice. The only place a "stop mining" notice is posted is the pinned issue #1, and only the author can post there.

A permanent main network is planned for 1 November 2026. That is an intention, not a promise: the date can move, and a launch would not make the software finished, reviewed or safe.
