BLOCK PROOF
not yet
GPUs are back · for good
Mined by GPUs.
Proven by fire.
A chain built so a chip gains too little to take your place. A mining program that rewrites itself every hour, so a chip built for one hour is useless the next. The same card proves every block and gets paid for it. No premine, no stake, no foundation, no merge to proof of stake.

A new program every hour. Last hour's chip is already obsolete. 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, August 2027.
Monero's idea, finished for GPUs
The random program that has kept chips off Monero since 2019 (approximate), rebuilt for graphics cards.

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

One chain, three jobs
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.
Deploy on IgneumOne click. The card mines and proves.
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.
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.

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%.

The litepaper states the limits before anyone else does. Proof lag, chip economics, the market size, and the one rule external review will try hardest to break.
