Proof for a World That Can No Longer Rely on Trust
TimeBinder helps people prove when files were created and protect their authenticity over time, because in a world that can no longer rely on trust, proof matters.
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.

Why TimeBinder Exists
AI has made it possible to fabricate anything from contracts and photos to audit trails and emails with no visible signs of tampering. For lawyers, auditors, and professionals who depend on evidence, this risk is existential.
It gives anyone the ability to prove when a file existed and to verify whether a presented file matches the original cryptographic hash recorded at that time.
TimeBinder solves that problem by anchoring each file’s cryptographic fingerprint to the Bitcoin blockchain, the most secure ledger on Earth. No file ever leaves your device. No data is exposed. Yet anyone, anywhere, can later verify when that file existed and whether a presented file still matches the original cryptographic record.
If a file is modified after TimeBinding, its hash will no longer match the blockchain-anchored record, making the change detectable during verification.
The Mission
TimeBinder’s mission is simple: To make proof permanent. We believe authenticity should be verifiable, not assumed. By combining cryptography, decentralisation, and the power of Bitcoin, TimeBinder provides the legal and professional world with tools strong enough to defend authenticity and integrity of digital evidence.
At its core, TimeBinder exists to make authenticity permanent. Whether you’re a lawyer, researcher, designer, or educator, TimeBinder helps you prove when files were created and preserve evidence that stands the test of time. In a world where AI can forge almost anything, TimeBinder provides simple, tamper-resistant proof of existence and timing.
TimeBinder focuses on proof of existence and timing. It does not assess authorship, accuracy, or legal admissibility on its own.
The Hidden Risk: AI Manipulation of Evidence
AI can now generate documents, signatures, and data trails that appear entirely genuine. When falsified evidence becomes indistinguishable from reality, trust alone no longer protects the truth. Immutable timestamps that are independent of systems, servers, or people are now essential.
With TimeBinder, you can prove when files were created using blockchain-backed verification.
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.
Ready to start TimeBinding your files?
In the digital age, proof matters more than ever. Whether you’re a lawyer, educator, or creative, TimeBinder helps you prove when files were created and keep a permanent, verifiable record. It’s simple, private, and built for a world where trust alone isn’t enough.
Why this matters: Digital evidence is now central to contracts, research, education, and design. When a file’s history can’t be trusted, disputes and doubt follow. TimeBinder gives professionals an easy, private way to prove when files were created, keeping integrity intact for years to come.
TimeBinder is used by lawyers, researchers, educators, and creators who need independent proof of when digital files existed in an AI-driven environment.
Frequently Asked Questions
Who founded TimeBinder?
TimeBinder was founded by Inna Hall and James Butt, an Australian lawyer and highly experienced software engineer who are also the creators of LawTram.com.au. They built the platform to provide tamper-resistant, blockchain-verified proof of existence for digital files in an era of AI-driven manipulation.
Does TimeBinder store my files?
No. Your files never leave your device. TimeBinder calculates a SHA-256 hash of your files directly in your browser. Only these hashes—mathematical fingerprints of your files—are used, meaning your content remains private and fully secure.
How secure is TimeBinder?
TimeBinder uses the Bitcoin blockchain, the world’s most secure and proven decentralized network, to timestamp your files. Every TimeBind creates immutable proof of existence that cannot be altered retroactively without detection.
How easy is it to use the TimeBinder app?
Extremely easy — no technical knowledge required. Simply drag and drop your files, choose your options, and confirm payment. Within moments, your TimeBind certificate is created and verifiable forever. The platform exists so people can prove when files were created and keep that proof over time.
How does TimeBinder protect my data?
All data in transit and at rest is encrypted. Since your files are never uploaded, only file hashes are processed. Verification happens within your browser or via the blockchain, ensuring total control and privacy. With TimeBinder, you can prove when files were created using blockchain-backed verification.
Can anyone verify my documents?
That’s up to you. You can make a TimeBind publicly verifiable via a QR code, or restrict access to specific email addresses. Either way, verification happens securely in-browser and no one sees your original files.
What problem does TimeBinder solve?
TimeBinder protects the integrity of important documents by anchoring their cryptographic hashes to the Bitcoin blockchain. This gives users permanent, independent proof of when a file existed, helping prevent disputes, forgery, and authenticity challenges.
What does TimeBinder prove and what does it not prove?
TimeBinder proves that a specific file existed by or before a particular blockchain timestamp. It does not prove who created the file, whether its contents are true, or whether it is legally admissible on its own.
Built for Proof That Lasts Forever
Every file you secure with TimeBinder becomes part of an unchangeable record anchored to the world’s strongest blockchain. Whether it’s a contract, photo, or design, your proof of existence is anchored to a blockchain record that cannot be altered retroactively. TimeBinder lets anyone prove when files were created and confirm they haven’t changed since.
TimeBinder helps you prove when files were created today and ensures that proof remains valid for decades to come, no matter how technology evolves.
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.
