Certelo

We’re officially opening the doors to the Certelo Closed Beta. Our first testers have received their invitations and are now getting early access to Certelo, helping us test, refine, and strengthen the platform before launch. The public Early Release is coming soon. Stay tuned!

Before filing a patent, keep your invention confidential and build dated, tamper-evident records of your R&D milestones without uploading your files: certelo.io/blog/protect-inte… #IntellectualProperty #Startups

Once mockups and brand assets go out for client review, you lose control over where they travel. Timestamp your design files locally before hitting send: certelo.io/blog/designers-cr… #GraphicDesign #FreelanceDesign

Before kicking off a training run, hash your dataset manifest and anchor it on-chain. You get dated proof of your exact data snapshot without uploading it: certelo.io/blog/document-dat… #DataEngineering #AIEthics

Attackers with root access can quietly edit local logs. Hash-chained, externally anchored logs ensure any deletion or change is mathematically detectable. certelo.io/blog/tamper-evide… #CyberSecurity #DFIR

Can You Prove a File Existed Without Uploading It? Yes. Certelo computes a file's SHA-256 fingerprint right in your browser and anchors only the hash to the blockchain. Your file never leaves your device: certelo.io/blog/can-you-prov… #PrivacyFirst #Cryptography

How do public blockchain timestamps compare to EU eIDAS qualified timestamps? A clear look at trust models, legal presumptions, and verification: certelo.io/blog/blockchain-t… #eIDAS #Compliance

Your pitch deck is often the first written record of your core thesis and architecture. Timestamp each version locally before sending it out to investors: certelo.io/blog/importance-o… #VentureCapital #Founders

When an AI output is overridden or approved, internal database logs can be edited later. Anchor human review records locally without exposing personal data: certelo.io/blog/human-review… #AIGovernance #EUAIAct

File "date modified" metadata is easy to alter. A SHA-256 hash paired with a blockchain timestamp proves whether a file changed down to a single byte. certelo.io/blog/detecting-an… #DataIntegrity #ProofOfExistence

Local SHA-256 hashing + public blockchain anchoring = verifiable proof a file existed at a specific time, with zero file uploads. Here is how it works: certelo.io/blog/how-does-blo… #ElectraProtocol #TechExplained

Certelo is now LIVE! Prove when your files existed with privacy-first blockchain timestamping. 🔒 Read the press release 👇 🔗 certelo.io/blog/press-releas… 🌐 certelo.io
