Who is mining, and how each round's pot is shared.
Share is your verified work in the period divided by all verified work. A proof at difficulty d counts as 2d hashes.

Measure this device: 5 seconds on every CPU thread, then 5 seconds on the GPU. Nothing is mined or sent while it runs.
Self-reported by the browser that ran the test. Shown for comparison only; it never affects credit.
UNDERMINEledger
Every payout, with its transaction. Balances are paid at round close once they cross the threshold.
UNDERMINEhow it works
From a random seed to SOL in your wallet.
Your tab asks the server for a challenge bound to your address: a random 32-byte seed and a difficulty in bits. Tickets last two minutes.
Web Workers on your CPU and a WebGPU compute shader on your GPU hash SHA-256(seed ‖ nonce), looking for a digest that starts with difficulty zero bits.
A hit is sent as its nonce. The server checks it with a single hash. Weak, reused, expired or borrowed proofs are rejected.
A proof at difficulty d is credited 2d hashes, the number of tries it takes on average.
Each address gets its own difficulty, tuned for about one proof every few seconds, so a phone and a GPU rig are measured the same way.
At round close the pot is split by share of verified work. Balances over the threshold are paid out and logged in the ledger.
Some hashes come in with more zero bits than the ticket asked for. Each extra bit is half as likely: +2 is an emerald, +4 a ruby, +6 an amethyst, +8 a diamond (one proof in 256). Gems are for show. Credit is always 2d.
Every accepted proof, from anyone, digs the shaft 25 cm deeper. Past set depths the cave breaks into a new layer: topsoil, coal seams, copper veins, crystal caverns, the magma rift and the core.
Everyone who sent a proof in the last minute works the tunnel next to you, tagged with a short address. Their gems land in the same cart, because the pot is shared.
