Trusted Timestamping & Blockchain Time Anchoring for the Veritize Platform
Time Stamping Authority — Your Digital Notary for Time
A TSA is an independent server that cryptographically certifies when a document or data existed, providing legally admissible proof of time.
Only the hash of your document is sent to the TSA — your actual content stays private and never leaves your system.
The TSA returns a digitally signed timestamp token that can be independently verified by anyone, anytime.
Contract, code, or any data
SHA-256 fingerprint
Only hash is transmitted
Adds time + signature
Proof of existence
Prove a contract or agreement existed before any dispute arose
Establish prior art and prove you created something first
Maintain tamper-proof audit trails for regulatory requirements
Prove exactly when a document was signed by all parties
A TSA is like a notary public for time — except it's digital, instant, available 24/7, and cryptographically verifiable by anyone in the world without needing to contact the original authority.
Verity Time combines three powerful verification methods
Proves WHEN
Proves UNCHANGED
Proves WHO/WHAT
WHEN + WHAT + WHO = Irrefutable Proof
Time Stamping Authorities operate under RFC 3161, an international standard that defines the protocol for requesting and receiving trusted timestamps. This ensures interoperability and legal recognition worldwide.
