Verify the commitment

Hash the revealed seed with SHA-256. It must match the commitment hash exactly.

Build the verification string

Combine the seed, Bitcoin block hash, and ticket count in this format:

Generate SHA-512 hash

Paste the verification string and generate the hash.

Convert hex to decimal

Convert the hexadecimal hash result to a decimal number.

Calculate the winner

Apply modulo to get the winning index:

decimal_result % 4 = winning_index

Tickets use 0-based indexing: the first ticket is #0, second is #1, etc. Learn more →
