Irium PoAW-X Testnet — Progress Update
The PoAW-X public testnet has been running for the past 24 hours and we want to share what has been happening.
The network is live with 4 independent nodes across 3 different machines and networks — our two seed nodes, a Windows node, and a Proxmox node run by community member rodb2008. All nodes are syncing correctly, all 48 consensus gates are enforced on every block, and the resource footprint is minimal — the node uses under 200MB RAM and near zero CPU at idle.
rodb2008 has also been doing a security review of the PoAW-X consensus code and found three real vulnerabilities which we are fixing in the next release. This is exactly the kind of independent review that makes the protocol stronger before mainnet activation. We are grateful for his contribution.
What we are working on right now:
Multi-miner support — the current testnet runs with a single miner. We are fixing the consensus rules so multiple independent miners can mine blocks and share rewards simultaneously. This is the core feature that makes PoAW-X fair and decentralized.
Security fixes — binding sybil proofs to the previous block hash to prevent replay attacks, enforcing minimum sybil work costs, and fixing deserialization to reject malformed payloads.
Once these are in the next release v0.1.2, the testnet will support genuine multi-party mining. When two or more miners are active the anti-domination engine activates, reward concentration drops, and the network adaptive mode shifts from Defense toward Normal — the full PoAW-X fairness model working as designed.
What this means for mainnet:
PoAW-X is not a rushed feature. Every component has been formally specified, simulated across 10 scenarios, tested with 2312 automated tests, and now stress tested by the community on a live network. Security findings from independent review are being fixed before activation. The activation height will be set with enough notice for all node operators to upgrade.
The goal is simple — Irium should never be owned by one miner, one pool, or one hardware class. PoAW-X makes that a consensus rule, not just a promise.

Two updates available today. If you run a node, update both.
Irium Core v1.0.131 (desktop wallet)
Download: github.com/iriumlabs/iriu…
iriumd v1.9.117 (node operators)
Download: github.com/iriumlabs/iriu…
What is new:
The MTP timestamp fix is now active at block 32,000. Block timestamps are now validated against the Median Time Past of the last 11 blocks, the same standard used by Bitcoin. This permanently prevents the timestamp drift that was causing inflated hashrate estimates on the explorer.
The block explorer now shows a coinbase tag on blocks mined by node operators who have set IRIUM_COINBASE_TAG on their iriumd instance. If you run your own node and want your blocks identified in the explorer, add IRIUM_COINBASE_TAG=YourName to your iriumd environment and restart.
Miners on the official pool do not need to do anything — the pool is already updated.
Urgent upgrade required before block 32,000 (~13 hours)
We have moved the MTP timestamp fix activation to block 32,000. This is a consensus change — all nodes must upgrade before this block or risk a chain split.
What to upgrade:
If you run an Irium node (iriumd):
Download v1.9.114 → github.com/iriumlabs/iriu…
If you use Irium Core desktop wallet:
Download v1.0.128 → github.com/iriumlabs/iriu…
Note: v1.0.128 CI is still building and will be available shortly. Check the releases page.
Miners on the official pool do not need to do anything. The pool is already upgraded.

PoAW-X will go through research, simulation, devnet, testnet, audit, and community vote before mainnet. Keep mining. The early miners who stayed are the ones who will matter most when this goes live. Thank you for believing in Irium. 🙏 #Irium#IRM#PoAWX#Mining#Blockchain
Work is assigned randomly every block. No miner knows who gets the next task in advance. The chain does not ask what hardware you have. It asks whether you completed valid assigned work. CPU miners. GPU miners. ASIC miners. All welcome.
To every CPU, GPU, and ASIC miner supporting the Irium network — thank you. After the block 22,888 hard fork, difficulty rose sharply. For CPU and GPU miners, finding a block got much harder. We hear you, and we have a plan. A thread on what comes next. 🧵
@yuanqidadudu Yes there was an issue with the stratum pool and we have pushed a hard fork to fix this issue for all CPU/GPU and ASIC miners. it will be fixed after the hard fork activates in the upcoming block 30000
Irium Core v1.0.9 is live 🚀
Major update for the IRM desktop node:
✅ Peer connection fixed — connects in 10-15s ✅ Settlement, Marketplace, Agreements all enabled ✅ Built-in help docs ✅ GPU miner multi-platform detection ✅ Explorer live block updates ✅ Settings auto-save

Community Bug Bounty Program — Irium
Irium rewards community members who find and report real bugs across any part of the ecosystem — the blockchain node, mining pool, wallet, desktop app, or documentation.
Rewards:
Critical (security, fund loss, consensus): 200–500 IRM
High (pool compatibility, wallet failures, node crashes): 50–100 IRM
Medium (broken flows, wrong data, failed transactions): 20–50 IRM
Low (UI issues, typos, minor errors): 5–10 IRM
To report a bug, ping in the discussion or DM me directly with a clear description of the issue, steps to reproduce it, and any logs or screenshots. Valid reports that lead to a confirmed fix will be rewarded within 48 hours.
Irium is built by its community. Every bug you find makes the network stronger for everyone.
Hey everyone,
Quick update on the Irium Core GUI desktop wallet.
We identified a bootstrapping issue that was blocking the desktop wallet from connecting properly to the network — nodes needed stronger peer gossip and runtime peer caching so the app could find and maintain connections without depending on the seed nodes every session. This has been fixed in the main repo.
If you are running a node, please pull the latest from GitHub:
git pull origin main
cargo build --release
This update improves how your node discovers and caches peers — once connected, your node will remember peers across restarts and gossip addresses to new nodes it encounters. The network gets stronger the more nodes run the updated code.
On the desktop wallet front — the Irium Core GUI full node desktop wallet is nearly complete. The bootstrap fix was the last major blocker for wiring the GUI to the network properly. We are now in testing and expect to release within a few days once everything is validated end to end.
Thank you for your patience and for keeping your nodes running. Every node makes the network more resilient.
