GPUs are back · for good

Mined by GPUs.
Proven by fire.

Built for graphics cards. A new mining program every hour, compiled on the card. 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 numbers. Every NVIDIA card from 8 GB proves and is paid for it; 12 GB and up mine and prove; AMD and Apple cards mine. No premine, no stake, no foundation.

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, August 2027.

Monero's idea, finished for GPUs

The random program that has kept chips off Monero since 2019 (approximate), rebuilt for graphics cards.

Property	RandomX	Igneum
Who mines	CPUs	GPUs
Program changes	Every hash	Every hour
Memory	2 GB, fixed	2 GB, growing (the proposed schedule, fixed at the testnet genesis: 2 GB, doubling at years 4, 12 and 28)
Verified by	Any CPU	Any CPU

The program keeps changing on a schedule fixed at genesis. Nobody touches it.

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.

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.

One click. The card mines; every NVIDIA card from 8 GB proves, 12 GB and up mine and prove.

Igneum Ember finds your GPU, makes a wallet for you and runs the node, the miner and the prover as one app.

The miner dashboard: hash rate, blocks found, node synced, a countdown to the next program, the block chart, the Apple M5 Max card mining, node and finality panels — Igneum Ember (the app is still labelled Igneum Miner until 0.3.6) on an Apple M5 Max, live devnet, 5 Oct 2026.

NVIDIA, AMD, Apple siliconFound by itself. One worker per card, several identities each.

A new program every hour, no pauseCompiled ahead and swapped in 0.01 ms on the live devnet, 0 rejected blocks.

Signed updates at a safe momentThe card keeps mining through the download. The old version comes back if the new one fails to start.

Tunes itself, in publicKernel variants raced every hour, hash per watt swept, every number in the bench table.

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.

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.

Testnet terms

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.

Your coins, your wallet

Igneum Wallet holds the key the miner makes for you and verifies finality itself. MetaMask works too.

Where Igneum is right now

Thirteen months, four public gates, each a measurement published pass or fail.

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.

No premine, no stake, no fee to any team in the protocol. Base fee burned. The one payment to the project is the Ember software's optional 1% dev fee, off with one flag. 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%.
