BLOCK PROOF
not yet
GPUs are back · for good
Mined by GPUs.
Proven by fire.
Built for graphics cards. A custom chip gains under 2x, and the model is public. A mining program that rewrites itself every hour, so a chip built for one hour is useless the next. An NVIDIA card with 24 GB or more proves every block and gets paid for it; AMD and Apple cards mine. No premine, no stake, no foundation, no merge to proof of stake.

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.
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.

One chain, three jobs

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 minerBuild
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.
Deploy on IgneumOne click. The card mines; an NVIDIA card with 24 GB proves too.
Igneum Ember finds your GPU, makes a wallet for you and runs the node, the miner and the prover as one app.
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.
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.
