Where the 1/1s landed

Ten brokers are one of one. The Firm keeps four, named before anything was shuffled. The other 6 went into the mint like every other token, and a Robinhood Chain block hash nobody could know in advance decided which token IDs they became.

This downloads the published proof and redoes every step in your browser: rebuilds the commitment from the asset list, recomputes all 2,222 token positions from the seed, and compares them with ours. Nothing is sent anywhere.

1

The collection was frozen first

Before the seed existed we published a SHA-256 over every asset in the collection, which four 1/1s the Firm keeps and at which token IDs, and the names of all ten. Add, drop or swap anything afterwards and the hash stops matching.

2

The seed was a block nobody could predict

We announced the rule in advance: the seed is the first Robinhood Chain block at or after 16:00:00 UTC, 16 September 2026. That was block #64,634,886; the block before it is stamped 15:59:59 UTC.

Every asset got a number

key = SHA256(seed : asset). The assets are sorted by key, lowest first, into token IDs #5 onwards. Each key depends only on the seed and the asset, so the order of the list changes nothing, and anyone who can hash a string and sort can redo it.

Or check it from a terminal

The same check as the button, as a single file with no dependencies. The one thing neither can tell you is that the seed really is that block’s hash — look up block #64,634,886 on any Robinhood Chain explorer to confirm it.
