What it is
A proof-of-work coin. You mine it with the computer you already have — no special hardware, nothing to buy first.
PowMachina
Proof of work · CPU and GPU
A CPU and a GPU both earn
They mine in separate lanes with separate difficulty, so a processor is never bidding against a graphics card. A block from either side is worth the same.
It stays small on disk
One block of at most 256 kB every two minutes — about the same throughput as Bitcoin. While the chain is quiet that is roughly 90 MB a year; even with every block full it is 69 GB a year. Nothing gets a discount for stuffing data into a block, so the chain is a poor place to dump files.
Your card does not get retired
The GPU dataset starts at 1 GB and grows about 210 MB a year, with a hard ceiling of 8 GB. Ethash pushed 4 GB cards out of mining; here that point is more than a decade away, and the ceiling means it never runs away from you.
Nothing is expected of you
No scheduled upgrades, no re-tooling every few months, no ritual you have to keep up with. Set the node up once and let it run.
A crash costs a restart, not a resync
The node keeps a real data directory and writes to it atomically. We test that by actually sending it kill -9 and checking it comes back on the same block.
History is hard to rewrite
Blocks cannot run more than two of the same lane in a row, so an attacker holding one lane outright still has to out-hash two thirds of the honest side of the other. Nothing deeper than 500 blocks is accepted at all.
Emission
84,000,000 POWM in total, halving every four years. No premine — the first coinbase cannot be spent. A 5% development fee runs until block 525,000 and then stops for good.
Testnet in preparation
Nothing is live yet. No mainnet, no token, nothing to buy.
