What Is Smart Contracts?
Self-executing programs on the blockchain that handle TimeProof timestamp anchoring.
Blockchain technology provides the infrastructure for permanent, tamper-proof record-keeping. Smart Contracts is a key concept in understanding how and why blockchain timestamps are trustworthy.
Why Smart Contracts Matters
In the context of digital evidence and file protection, smart contracts plays a critical role. Here is why you should understand it:
For Creators and Professionals
When you need to prove that a file existed at a specific time, the underlying technology must be trustworthy. Smart Contracts is part of what makes TimeProof timestamps independently verifiable — anyone can check the proof without trusting any single company or authority.
For Legal and Compliance Teams
Evidence must be reliable, understandable, and verifiable. Understanding smart contracts helps legal professionals explain to courts and regulators how blockchain-based evidence works and why it should be trusted.
For Developers and Technical Teams
If you are integrating timestamping into your application or workflow, understanding smart contracts helps you make informed architectural decisions and explain the technology to stakeholders.
How TimeProof Uses Smart Contracts
TimeProof leverages smart contracts through its use of the Polygon blockchain. Every timestamp is anchored using this concept, ensuring permanent, tamper-proof records that anyone can verify on a public block explorer.
How Blockchain Timestamping Works
When you timestamp a file with TimeProof, TimeProof uses client-side file hashing (SHA-256). That 64-character value is the unique fingerprint for the exact version you selected, and if even one byte changes, the hash changes too. Your file never leaves your device.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. The blockchain records the hash, timestamp, and transaction ID permanently, so anyone can verify the record independently on Polygonscan.
This is where smart contracts stops being theory and becomes a usable proof workflow.
Practical Example
Consider a photographer who timestamps their portfolio images. The smart contracts ensures that the timestamp record is permanent and trustworthy. No one can alter the record after it is written, providing the photographer with irrefutable evidence.
Key Takeaway
Smart Contracts is not something you need to understand to use TimeProof — the platform handles all technical details automatically. But understanding it builds confidence in the technology and helps you explain it to others when your proof is challenged.

TimeProof packages this live workflow into one unified credit system, so you can apply the concept above to real files without needing crypto expertise.
- Scheduled timestamps: 1 credit per file - available to everyone, with proof available within 6 hours.
- Instant timestamps: 2 credits per file - available to verified subscribers, anchored in about 2 seconds.
- Legal-Grade: Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.
One-time packs start at $15 for 100 credits. Verified monthly plans start at $19/month and include identity verification for instant timestamps and Legal-Grade.
Scheduled timestamps handle routine proof, verified instant timestamps handle immediate needs, and Legal-Grade adds the formal evidence package when the matter is higher stakes.
