1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 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

Isa brots blomin milli hnignunar marnars barna
Morgunn í grárri vindhjálmars þoku við berufjörð
Velkomin i lífid, avarpar madr sjalfan sig
Haka kleifir berja ok brjota vid enda langrar ferdar sinnar
Vid fundum nytt heimili, langt burtu i vestrinu
Pat er stormr ok blakold vatnssmídin litar regna borg
Fra pogn Rauma grund hefr þessi aett komid
Gyldis kind hefr aldrei dvalist a einum stad
Svo lengi sem Sutrs aett ok asmegir adhafast, mun pessi jord i ringulreid elta

Isa Brots Blomin Milli Hnignunar Marnars Barna
Morgunn Í Grárri Vindhjálmars Þoku Við Berufjörð
Velkomin I Lífid, Avarpar Madr Sjalfan Sig
Haka Kleifir Berja Ok Brjota Vid Enda Langrar Ferdar Sinnar
Vid Fundum Nytt Heimili, Langt Burtu I Vestrinu
Pat Er Stormr Ok Blakold Vatnssmídin Litar Regna Borg
Fornjóts Synir Ljótir At Haddingja Lands Lynláðum
Vandar Jǫtunn Reisti Fiska Upp Af Vǫtnum
Saga á tveim tungum II: Eigi fjǫll né firðir
Gamalt ríki faðmar þá grænu ok svǫrtu hringi lífs ok aldrslita
Er hin gullna stjarna skýjar slóðar rennr rauð
Um nóttu, mér dreymir þursa þjóðar sjǫt brennandi
Ek sá halr at Hóars veðri hǫsvan serk Hrísgrísnis bar
Hvítir hjǫrvar Heimdalls aldraðra fjallgylða
Er faðir kulda ok myrkrs hopar fyrir endalausum vegi Ránar
Eftir bjartlogar hróts hreggs kveikja ógnarstríðan úlf storðar í grasinu
Nú er lengstu miskunndir dalreyðar ná hátindi
Ek sneri aftr til golfhǫlkvis fleygra sárelda heiftar
