GPUs are back · for good

Mined by GPUs.
Proven by fire.

The first chain built so no chip can ever take your place. A mining program that rewrites itself every hour, so no chip can be built for it. The same card proves every block and gets paid for it. No premine, no stake, no foundation, no merge to anything else, ever.

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.

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. 80% of each block to its finder.

Get the miner

Prove

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

How proving pays

Build

Ethereum bytecode unchanged, with 20% of priority fees paid back.

Three ways a card gets paid

One client switches the card between hashing and proving by itself.

01

Block reward

80% of emission to the miner who wins the block.

02

Proving the chain

20% of emission plus a share of every block's gas.

03

Proving for others

Rollups and bridges pay for proofs in their own money.

Read what Igneum does not claim.

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.
