Certify Your Ideas on the Bitcoin Blockchain

Proxae provides a robust solution to permanently certify your texts, ideas, and files by anchoring their fingerprints to the Bitcoin blockchain. This ensures that your creations are verifiable forever, independently, and without requiring any trust in a third party.

• Timestamping: Securely timestamp any text, idea, or file to prove prior existence.

• File Certification: Supports all file types (PDF, DOCX, TXT, JPG, PNG, ZIP, MP3, MP4, etc.) with a maximum file size of 50 MB. The fingerprint calculation is performed locally in your browser, ensuring your content never leaves your device.

• Web Page Capture: Certify web pages by capturing their content. An account is required for this feature, which is free to sign up for.

• Verifiable Proof: Proxae anchors the SHA-256 fingerprint of your content into the Bitcoin blockchain using OpenTimestamps. This creates an immutable and permanent proof of existence.

• Interactive Demo: Experience a 30-second interactive demo to see how Proxae anchors your proof in the Bitcoin blockchain.

• Free and Unlimited: Try Proxae for free with no sign-up required for basic certification.

How it Works:

1. Upload/Input: Drop a file or provide a web page URL.

2. Fingerprint Calculation: A SHA-256 fingerprint is computed locally on your device.

3. Bitcoin Anchoring: The fingerprint is anchored to the Bitcoin blockchain, creating a permanent record.

4. Confirmation: The certification is confirmed and immutable, verifiable at any time.

Proxae leverages the tamper-proof nature of the Bitcoin ledger to establish prior existence with cryptographic strength, serving as a reliable alternative for idea prior art and Soleau envelopes.
