Irium (IRM) mining — PoW parameters and early network observations

[irium]

This thread is for technical discussion of Irium (IRM) mining and early network behavior.

Irium is a mine-only Proof-of-Work chain. There was no premine, presale, or airdrop.

────────────────────────────────
Mining Overview
────────────────────────────────

• Proof-of-Work consensus
• Mine-only distribution
• Multicore CPU mining supported
• Public mining software
• Official SOLO Stratum pool now available (see below)

────────────────────────────────
Official Stratum Pool (SOLO)
────────────────────────────────

Stratum URL:
stratum+tcp://pool.iriumlabs.org:3333

Username:
IRM_ADDRESS.worker1

Password:
x

Payout Model:
SOLO — block reward is paid directly to the IRM address used as username.

Notes:
• Native Rust Stratum implementation
• Direct integration with iriumd
• Template refresh every 3 seconds
• Pool fee: 0% (initial phase)

────────────────────────────────
Mining Notes
────────────────────────────────

• The miner utilizes multiple CPU cores by default
• Actual performance depends on core count, CPU architecture, and OS scheduling
• Early hashrate variance is expected on a small network

────────────────────────────────
Current Network Notes
────────────────────────────────

• Early-stage network with a small number of public nodes
• DNS-free peer discovery
• Initial connectivity depends on reachable peers being online at startup

Troubleshooting notes for “no peers”, mobile/Termux setups, and miner behavior at height 0 have been added to the repository documentation.

────────────────────────────────
Discussion Topics
────────────────────────────────

• Multicore mining performance on different CPUs
• Difficulty adjustment behavior at low hashrate
• Solo mining observations
• Peer connectivity from miner-operated nodes

This thread is intended for technical feedback and observations, not promotion or price discussion.

followed steps on github, get to this, and get this response

./target/release/iriumd

Failed to load anchors: anchor signature verification failed: valid anchor signatures below threshold: 0/1

Any ideas?

[irium]

That error means the node could not verify the signed bootstrap anchors file.

Irium verifies bootstrap/anchors.json using ssh-keygen’s signature verification (-Y) and the allowlist in bootstrap/trust/allowed_anchor_signers. If your OpenSSH is too old (no “ssh-keygen -Y”), or those files are missing/modified, verification returns 0/1 and the node exits.

Quick check (please paste output):

ssh-keygen -Y verify

If you see “unknown option” / usage output, your OpenSSH is too old. Fix by updating the OpenSSH client:

Ubuntu/Debian:
  sudo apt update
  sudo apt install -y openssh-client
  ssh-keygen -V

Fedora:
  sudo dnf install -y openssh-clients
  ssh-keygen -V

Windows:
  Use WSL (recommended) or update the “OpenSSH Client” optional feature.

Also make sure the repo files are clean (no local changes):
  cd ~/irium
  git reset --hard
  git clean -fdx
  git pull origin main

Then rebuild + run again:
  source "$HOME/.cargo/env" 2>/dev/null || true
  cargo build --release
  ./target/release/iriumd

If it still fails, please confirm these two files exist and are unmodified:
  bootstrap/anchors.json
  bootstrap/trust/allowed_anchor_signers

[irium]

At the moment, Irium is run via CLI for node operation and mining.

That said, we’re actively working on an Irium Core GUI that brings everything together in one place — a full node, desktop wallet, and built-in mining controls. The idea is to make it easier for miners to get started without changing how the network works under the hood.

CLI will remain fully supported for those who prefer it or are running servers. The GUI will simply be an alternative once it’s stable and ready.

More details will be shared when there’s something concrete to test.

POOL UPDATE — Official Stratum Live

The Irium native Rust Stratum pool is now publicly accessible.

Algorithm: SHA-256d
Stratum: stratum+tcp://pool.iriumlabs.org:3333
Mode: SOLO (reward paid directly to miner address)

ASIC miners (Antminer / Whatsminer) are welcome to test.
If you connect successfully, please share:
- Miner model
- Firmware version
- Log snippet

Pool fee is currently 0% during the initial phase.

NETWORK STATUS

Current height: 14627
Stratum: Online
Port 3333: Open
Template sync: Active

Early miners welcome.
