Cryptographically seeded PRNG. Fisher-Yates shuffle. Seed committed to Solana before entries are collected. Anyone can replay the shuffle and verify the winner.
Three steps from tag to verified winner.
A 64-character hex seed is generated from OS-level entropy. Its hash is anchored to Solana via a memo transaction before any entries are fetched. This proves the seed existed before the pool was known.
Replies, retweets, and quote tweets are fetched. Conditions applied: follower checks, hashtag requirements, tag counts, account age, fraud filters. Bot entries and duplicates removed. Pool capped by tier.
Entry pool is sorted, hashed, then shuffled with a Fisher-Yates algorithm using the pre-committed seed. Top N entries are winners. Pool hash and winners hash are anchored to Solana. Result posted inline.
Every pick produces a verification page with these fields.
To verify independently: download the entry pool, sort IDs, hash with SHA-256 to confirm pool_hash. Then run Fisher-Yates with the seed. The first N entries in the shuffled list are the winners. The client-side verifier on the verification page does this automatically.
