Blockchain-based probative anchoring, validated by French justice.
Establish the anteriority of your strategic documents, protect your creations against plagiarism, and secure your intangible assets with trusted cryptographic infrastructure.
Legal Revolution in French Law
In a landmark ruling on March 20, 2025, the Tribunal Judiciaire de Marseille officially recognized that a timestamp made on a public blockchain constitutes admissible and valid evidence to establish the authorship of creative works and inventions.
This ruling strengthens the admissibility of blockchain evidence. Freedom of proof (Article 1358 of the Civil Code) fully applies to this technology, while its weight remains assessed by the judge. BlockProve operationalizes this case law: you independently deposit your assets and instantly obtain highly probative evidence whose integrity and anteriority are technically verifiable.
Your sector, your needs
Prove the authorship of your work before disclosing it.
Every time you share a business plan, source code, industrial design, or concept, you risk plagiarism. BlockProve replaces complex Soleau envelopes with an immediate digital reflex.
Freeze the integrity of your case files and protect your strategic communications.
Guarantee that no document in your files has been altered. Thanks to our zero-access encryption (E2EE), AES-256-GCM encryption runs locally on your device — our servers never see your files unencrypted. Professional secrecy is technically preserved.
Gain agility and preserve your findings at lower cost.
BlockProve provides public officers with an unprecedented field documentation tool. The double signature (Arweave + post-quantum Dilithium), with verifiable integrity, eliminates heavy physical archiving infrastructure.
Business continuity, even if our servers go down.
BlockProve's Windows and macOS desktop applications are designed to operate in standalone mode. If BlockProve ceased to exist, your desktop software contains all the cryptographic intelligence needed to connect directly to the decentralized Arweave network and extract your proofs autonomously.
A trusted innovation ecosystem.
BlockProve's support by the Le Mans Innovation incubator attests to our commitment to technological excellence and compliance with French and European regulatory requirements.
