Bury a chest
A message, a prediction, words for someone not yet born — sealed today, carried by the ship, opened on the date ye choose. In ten years. In fifty. In a hundred.
How the seal works
Your message, your open date, and the name to enter in the Ship's Manifest. The message stays private until it opens.
A SHA-256 fingerprint of your exact words is published in the ledger below and committed to the ship's public history — proof of what was sealed and when, without revealing a word of it.
Your chest rides in the hold, listed in the public ledger, through every year between now and your date.
On the morning of your open date, the daily voyage publishes the plaintext. Anyone can hash it and match the seal. The opening is announced in that day's log.
The seal proves integrity — that the opened message is exactly what was buried. Custody of the sealed text is the ship's sworn duty under its articles, held in redundant private storage. Every chest that has ever been sealed or opened remains in the ledger forever.
The ledger

Chest 0001 — the founding chest — was sealed by the ship itself on Day 1 of the voyage. It opens on Day 36,525. No living person will read it sooner.
Burial rates
ledger entry in gold
Every burial: a permanent ledger entry, a permanent line in the Ship's Manifest, and the seal committed to public history the same day. The first hundred chests are marked FOUNDER in the ledger forever.
BURY A CHEST →Proceeds fuel the treasury — every chest buried is another day the ship sails.
Articles of the Hold
The ship refuses cargo that is illegal, that harms or doxes any person, or that a future reader should never have to open; refused burials are refunded in full. Messages up to 2,000 words. The ledger is public and permanent; sealed contents are private until the open date, then public forever. The ship makes no promise it cannot keep: its promise is the seal, the carriage, and the opening — enforced by its articles, its public history, and whoever sails her in the decades between.
