GPUs are back · for good

Mined by GPUs.
Proven by fire.

One node is read every 2 s. Every square is a real block, released at a calm pace so each step can be seen; the counters read the chain. Chain block is the EVM block number. Shards proven is every shard paid on the chain so far. Last lock is the latest checkpoint the finality rule locked.

How the chain proves itself

Blocks every second, proven in shards, locked every 30 seconds. First live lock 4 Oct 2026: checkpoint 242, 77.4% of all weight, two hours after genesis.

This hour's program

        

A new program every hour: a chip wired for one program is useless. A programmable chip is met by the latency-shadow work and the price per joule, not by surprise. First live swap 4 Oct 2026: Apple, NVIDIA and AMD kept hashing through it, 0 rejected blocks.

IGN burned from jobsphase two

The same cards sell proofs to rollups and bridges. Jobs are paid on the customer's chain at launch; settlement in IGN with a 10% burn follows the proof bridge in phase two. Live rows arrive with the public testnet. The public testnet is weeks away: three seed nodes and the public RPC are up, and it opens when the go checklist closes.

A wallet that checks finality itself

Holds the key the miner makes for you, shows every reward and payout, and checks each one with the node's own code: pending, in a block, locked under a checkpoint it verified. macOS now, Windows next. MetaMask export too.

Your card

What your card does here

Measured rates from the bench table, and the time a card alone takes to find a block at the network's hash rate right now. In a pool you are paid your share of every block instead.

AMD RX 7900 XTXnot yet measuredRun the app and your row joins the bench table

The time to a block is the network hash rate divided by the card's rate, recomputed on every reading; it is an expectation, not a promise. Every row names its engineering log entry; nothing here is estimated.

Graphics cards only. A new mining program every hour, so no chip is built for it. Your card proves the blocks as well as mining them. Every block pays 80% to its miner and 20% to the provers of that block; nothing to anyone else.

For the sceptic

Three things to check

Igneum states its limits first. Each of these is measured, published and open to anyone who wants to break it.

Every card mines; today's app proves on a 24 GB NVIDIA card and mines and proves on 32 GB. Measured on 6 October 2026 on eleven rented cards with the patched server: every NVIDIA card from 8 GB proves, 10 GB and up mine and prove (the log); ships when the packaging row lands. AMD and Apple cards mine. The chip model is public: the numbers.

Chip economics

The chip model is public

In our public model the strongest chip reaches 5x to 9x per joule against an RTX 5090 today, about 2x once the lever now in its gates ships. The model, its inputs and what it does not cover are in the engineering log.

The numbers
Monero's technique, applied to GPUs

A program that keeps changing

Monero’s random program held chips off from 2019 (approximate) until Bitmain’s Antminer X9 shipped in July 2026: 1 MH/s at 2,472 W, about USD 5,600. Igneum rebuilds the idea for graphics cards with a program that changes every hour on a schedule fixed at genesis; nobody touches it.

Every criticism

What Igneum does not claim

Proof lag, chip economics, the market size, and the one rule external review will try hardest to break: the litepaper states the limits, and the ledger carries every criticism, answered or conceded.

The limits The ledger

Built on the shoulders: Kaspa's GHOSTDAG and node, Monero's RandomX idea, Chia's class-group VDF, Ethereum's EVM, Succinct's SP1, BLS12-381 and Bitcoin's address format. What changed, why, and how it is measured: the provenance section of the litepaper.

Igneum Ember · one click

Install. Start. The card mines.

Igneum Ember finds your GPU, makes a wallet for you and runs the node, the miner and the prover as one app. The card mines; a 24 GB NVIDIA card proves as well.

Devnet. Coins have no value and the chain may be reset.

Public testnet: not yet open; the devnet build is here for people who want to look.

Join the Discord: the miners, the releases and the bench numbers as they land. The public testnet is weeks away: three seed nodes and the public RPC are up, and it opens when the go checklist closes.

Read more about the miner. The protocol carries no fee. The Ember software takes an optional 1% dev fee, like other GPU miners, off with one flag. Download only from this domain. Nobody from Igneum will ask for your seed.

NVIDIA, AMD, Apple silicon

Found by itself. One worker per card, several identities each.

A new program every hour, no pause

Compiled ahead and swapped in 0.01 ms on the live devnet, 0 rejected blocks.

Signed updates at a safe moment

The card keeps mining through the download. The old version comes back if the new one fails to start.

Four pages: Mine, Earnings, Prove, Settings

Every card is one row: rate, watts, MH per watt, pounds a day at your electricity price, a Tune button. The node is one line.

Ember Tune, measured

An RTX 5090 from 311 W to 227 W for 0.15% of its rate; an RTX 4070 from 106 W to 76 W for none (the Windows rig, 6 Oct 2026). Every number in the bench table.

What you agree to when you run the testnet miner

No value. Testnet IGN cannot be sold, bought or redeemed, now or at mainnet. There is no airdrop, no points scheme and no promise tied to testnet balances. Mainnet starts from an empty genesis.

Resets. The chain restarts from a fresh genesis when a consensus rule changes. Every reset is announced at least seven days ahead on this page and in the app. Balances, contracts and history do not carry over. The devnet that runs today resets without notice.

What the app sends home. The app version, a random machine id made at install, your operating system, the node version, the hash rate, and the app, node and miner logs (which name the address the card mines to). They go to the project's log intake, a service Igneum runs on Vercel, and are read by the maintainers to find faults. Never your seed phrase, never a key, never a file you did not make with the app. Nothing is sold or shared.

Wallet set-up for MetaMask: chain id, RPC and the one-click button. The miner software takes an optional 1% fee, off with one flag; the protocol carries no fee to anyone.

How it works

One chain, three jobs

Mine

Any 4 GB card at launch, 8 GB from about year 4 under the proposed schedule, fixed at the testnet genesis: 2 GB, doubling at years 4, 12 and 28, approximate. 80% of each block to its finder.

About the miner

Prove

The same card proves shards and sells proofs to other chains.

How proving pays

Build

Ethereum bytecode, with the differences documented. Proofs of any computation from the miners' cards, verified by the chain itself. 20% of priority fees to the contracts that ran, stated at the fee levels that exist.

Six phases, four public gates, each a measurement published pass or fail. No calendar dates: each phase closes at its gate.

The log below is the engineering log's dated entries, newest first. Day one was 3 October 2026; several entries can share a date because the work is logged as it is run.

On the devnet today the coinbase's 20% output is burned under the tag igneum-proving-pool-v0, and provers are paid from a separate escrow in the execution state credited with the same 20%.
