What is TimeBinder and How Does it Work?
TimeBinder proves when a digital file existed by creating a cryptographic fingerprint of the file and anchoring it to the Bitcoin blockchain. The file itself is never uploaded or stored.
Verification can be made public or restricted by the user. In either case, the blockchain record proves the file existed at that point in time and has not been altered.
What about quantum computing?
Quantum computing is often raised as a concern when blockchain technology is mentioned. This concern is understandable, but commonly misunderstood. TimeBinder relies on cryptographic hashing (SHA-256) to anchor proof of file existence, and there is currently no known practical quantum attack against SHA-256.
While some public-key cryptographic schemes could be affected by future large-scale quantum computers, Bitcoin’s protocol is designed to evolve. Cryptographic upgrades can be implemented well before any realistic quantum threat becomes practical, preserving the integrity of historical records.
Importantly, TimeBinder does not expose private keys or rely on long-term signature security to prove existence in time. It anchors cryptographic fingerprints to the blockchain, creating an independently verifiable historical record that remains valid even as cryptographic standards change.

Lock in your most precious information. Immutably.
Select your files
Your file is hashed locally
in your browser.
TimeBinder never uploads or stores your files.
Submit your TimeBind
TimeBinder submits your file’s cryptographic hash for anchoring on the Bitcoin blockchain.
This creates an independent timestamp that can be verified later.
Receive your certificate
You receive a Proof of Time Certificate showing the blockchain proof details needed for independent verification.
