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 0x36ebe430bde8886b65162ebe089fc3ab503681cdbaea7ca610a3fb977554790d. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).

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.

Maharana Jang Me Jame Ang Me Dahakti Agni
Peeth Fair Gaye Baith Piya Mijan Thik Na Tera
Wa Nayi Naveli Naar Najro Se War Kare Hai
Sarvar Ne Ghada Dubkaya Bhup Ne Yo Andaj Lagaya
Amar Singh Hai Chhatri Jat Jurmane Ki Sunke Bat
Piya Matna Jua Khail Jhelne Kasht Hame Pad Jainge
Aj Apke Dwar Pe Raja Daan Mangne Aya Mai
Badh Gayi Saadak Me Heer Ranjha De Diya Dikhayi
Balam Ji Ghadwayde Mera Das Tole Ka Haar
Cheej Parayi Dekh Ke Chhore Tu Kyu Pagal Hora
Chitthi Padh Padh Ansu Aa Rare Piya Ranj Konsa Aaj Hua
Data Raji Daan Karan Me Munji Raji Dhan Me
Dilli Ka Darbar Bhara Sach Shakti Singh Bole Tha
Dropat Ki Bani Sunke Ho Gaye Rakh Jal Bhunke
Ganga Jamuna Gau Mata Ko Aj Bachana Hoha
He Jagjanani Sherawal Ab Prakat Ho Jao Ma
Ho Papi Shetan Ade Te Kis Bhagan Ka Nam Nahi
Kar Khamosh Hosh Kar Dil Me Dubega Bin Pani
Kashi Ke Me Lagi Adalat Pakchhi Mare Par Konya
Ke Bera Tha Meri Gelya Kasht Uthane Pad Jainge
Kit Alakh Savere Chali Re Gori Hoke Ne Taiyar
Lash Ke Upar Pad Ke Roye Sarvan Ke Pita Aur Mat
Mai Sang Chalun Bartar Bhole Ki Kawad Laun
Matna Mare Ri Bhabhi Tane Na Devar Chale Tere Bahane
Unche Sur Me Gavan Lagi Aur Nachke Tal Bajadi
He Mrig Nayni Mere Se Tu Shadi Ki Hami Bharle
Kuchh To Bolo Maharaj Aj Kyu Thari Dasha Bigad Ri
He Guru Dev Tere Gurukul Me Sikchha Pane Aya
Chali Tu Kit Jhola Thake Baba Ke Darshan Karne
Panchal Desh Kampilya Nagar Me Aj Bhid Hai Bhari
Tut Gira Asman Dharan Pe Sushma Mukhda Mod Chali
Tere Bin Ji Lage Na Mat Akeli Chhod Bhartar Mene
Vyas Muni Sanjhavan Lage Bhup Dhyan Har Ka Dharle
Udja Re O Pakchhi Lotke Chittod Jatu Mere Dham Ko
Sodagar Ka Jahaj Chhut Gya Chala Chirta Pani
Pardesha Se Chitthi Ayi Byat Bigad Gya Mera
Mat Par Tirya Te Mail Karo Yaki Jhuthi Pave Yari
Milne Chale Hai Shankar Janme Nandlal Ji
Sun Lakkadhare Bat Manja Tu Mat Shadi Kar Mere Sath
Pachhtayega Re Pachhtayega Gya Samay Hath Nahi Ayega
9 Grahon Ke Beech Ghira Chandrama (Hindi)
Fas Gaya Ab Itihas Keher Ke Jal Me (Hindi)

Kanwadiyao Ke Tole Bol Rahe Bumbum Bhole
Kaali Kholi Chaali Ja Teri Kat Jagi Bimari
Aa Jaiyo Radharani Mat Kariye aaj Bahano
Teri Nagri He Badi Door Babaji Kaise Aaun Me
