two checks, both done in this tab. nothing is sent anywhere except read requests to the chain.

a share

paste a challenge, the beneficiary address and a nonce. the page computes keccak256(challenge || beneficiary || nonce_le) and compares the first 8 bytes to the target.

waiting for input.

a block

paste a coin mint and a block number. the page reads the coin's ring from chain and recomputes sats_per_share = reward × 10^9 / shares and what the block paid.

waiting for input.
