NightBirds are live on Midnight.

Twenty one-of-a-kind birds, one hidden in each window of serials.

Serials 21 to 8887 are cut into twenty windows, each 1.2 times wider than the last, and each window holds exactly one piece. Which battle in a window gets it is decided by a Cardano block that did not exist when that battle's seed was committed, so no seed can be chosen to land a 1/1. The schedule was published before deposits opened and is never edited.

Schedule: collections/gen2/oneofones/schedule.json, sha256 c05988a0c71f62632ec7efd8b7209fa59371c8bf55810f2ecd39d5f265ded07f. The minting service reads that file once and refuses any other bytes.

What the draw proves

Given a battle's seed, its two deposits, the serial, and the reserved set that draw saw, the verdict follows from the published schedule and rule. The seed is committed on chain, in the first deposit's datum, before anyone accepts. The beacon is a block that did not exist when that commitment was made. So the seed cannot have been chosen, after the fact, to land a particular 1/1.

What it does not prove. This rests on us, and we say so.

• We control settlement order. When more than one battle is ready, the order in which we mint them decides their serials, and so which of them can receive a 1/1. At a window's last serial, whichever battle we mint next receives that window's piece.
• We can withhold battles. We draw every seed and see each outcome before we settle. We could decline to settle a battle, or run battles of our own and settle only the ones that land a 1/1. A withheld battle's owners reclaim their NFTs after the deadline. We do not claim that every such skip is publicly visible or attributable.
• Exclusive minting. The draw assumes the minting service is the only writer of serials 21 and up. The contract admin can mint directly. A direct mint consumes a serial without running the rule. The boot history check then halts, but it cannot give that serial back.
• Finality. The beacon assumes no Cardano rollback deeper than 10 blocks. It is re-read before submit and after confirmation, and a change halts minting.

Twenty birds, minted the day mainnet opened.

Twenty Cardano NFTs were given up to found this collection, and each of these birds carries the name of one of them, written into its token for anyone to check.
