Every donation to The Future Party is cryptographically chained to the previous one using HMAC-SHA256. If any record is tampered with, the chain breaks — and this page detects it automatically on load.

Download the full chain and verify independently. Each entry's previous_hash must match the prior entry's chain_hash. The sum of all amount_cents must equal the displayed total. No gaps in sequence_number. The genesis entry uses a well-known seed.
