Verify it yourself
The hash above is SHA-256 over this receipt's canonical JSON: keys sorted, no spaces, UTF-8. Re-hash it in one line; you should get 178613beb8cd…5cbd0a0e:
curl -s https://verano-square.fly.dev/api/turf/receipts/c994903-downtown | jq -cjS .receipt.document | sha256sum
That rebuilds the canonical form from the JSON with jq -S (jq 1.6+). Or hash the exact stored bytes: curl -s https://verano-square.fly.dev/api/turf/receipts/c994903-downtown/canonical | sha256sum
- Chain. The document includes
prev_hash. It must equal the previous receipt's hash (b994889-k12-claim), so no earlier receipt can change without breaking every one after it.
- Source. Every value under
facts is copied from grift.world's public feed, same keys, same values. While the city still lists it (about the last 14 nights; the last 300 burns), compare:curl -s https://www.grift.world/api/crews | jq '.nights[]|select(.day==994903)|.contests[]|select(.d=="Downtown")'
- On-chain. Open each burn's tx on Robinhood Chain's blockscout. It should show the war chest wallet sending the amount to the burn address.
