1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x132d921d81a667aed4c266ff08acc2bae88a115f8d75e74d985fd21c61a080a8. Chain 2 (Bitcoin): anchored in block 953678 (2026-06-14T19:23:11Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/617b2cd0-bc32-4660-bcb5-f1a56d9fde1d.json and https://artists.proofprofile.net/proofs/artist/617b2cd0-bc32-4660-bcb5-f1a56d9fde1d.ots, run `ots verify -f record.json proof.ots` (https://opentimestamps.org).
1. Confirm isrcCode identifies the recording in the pre-2022 source corpus and cc-db-prod record 2. GET OTSVerificationAPI → server-side canonical-record, hash, and attestation checks must pass 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch

I Have Traveled Years In Search Of The Edge Of The Megalopolis, Nature May Not Exist, There Has Been No Sign Of Life
A Time Behemoth Has Sent Me To An Unknown Megalopolis Timeline for Reasons Unbeknownst To The High Councel
God Has Given Me A New Rank, During Vigil A Holy Empire Has Made Me King
TRACKING THE DIAMOND AMPHISBAENIAN THROUGH THE RUINS OF THE FORBIDDEN CRYPT, WHY HAS IT NESTED HERE?
Ripped Into A Purgatory By The Spirit of A Slingjaw Werebore, I Must Escape Before Judgement
Cleaning Up The Havoc of The Spectral Wraith and Restoring The Nether Temple For The Night Wardens
I'M STARTING TO THINK THE GLACIAL WARDEN DOESN'T WANT ME TO LEAVE THE SUBZERO FOREST
IF I DON'T STOP THE VIRIDIAN VIPER IT WILL DESTROY THE GATHERING HUB AND ALL THE MERCHANTS WILL PERISH
STUCK IN THE FROZEN DESSERT I CALLED FOR HELP AND THE YETI OF THE DAMNED ANSWERED
GET AWAY FROM THE EBONCLAW DREADBEAST THAT THING DONT PLAY
CHOSEN BY SOULREAP CRESCENT TO SLAY GLOOMFANG THE SHADOWSPINE
THE ALPHA NAGGA FINALLY SPIT ME OUT, I THINK I SEE A SAND KINGDOM IN THE DISTANCE
I WAS SENT TO KILL THE DEMON DRACO, BUT I HAVE RETURNED TO DESTROY EVERYTHING
HOSTING THE SHADOWREAVER'S SPIRIT TILL IT REMATERIALIZES BACK INTO ITS APEX FORM
I CANNOT RETURN TILL I HAVE HARVESTED FROM A DEATH SLAAD
HIDING MY SCENT FROM THE GRAVEBORN OWLBEAR

NOXIOUS OGRES KILLED MY FAMILY IN A RITUAL NOW I'M A ROGUE
