The record

Each item says where it comes from and what it proves. Status now: SETTLED · 1 pt.

AuthorONCHAIN

@404nobody · 0x1c2d7b5a5f42c15980b3008e8d5a0c605c657f22

The author's wallet signed the call (EIP-712). The contract checks that signature, so the platform relayer cannot make calls for anyone.

Ticker and roundONCHAIN

$NVDA · round 2026-10-23 · cutoff 2026-10-24 16:00:00 ET

Round ids are the anchor session date. The round's times are fixed onchain when it is scheduled.

Shows the commitment was recorded onchain in that block. It does not show the bucket, and it does not make the call correct.

Hidden until the cutoff. The reveal transaction proves the bucket and salt hash to the anchored commitment.

The registry stored this result. Settlements are append-only; a correction is a new public version.

Sequencer checkPLATFORM DB

unavailable

Chainlink lists no L2 sequencer uptime feed for Robinhood Chain, so this check could not run. A sequencer outage around the reference time would not be detected automatically.

ScorePLATFORM DB

score-v0-provisional: exact bucket 2, right direction 1, else 0. Provisional and versioned; VOID, unrevealed and expired calls are not scored but stay on the record.
