VERI
Cryptographic proof & timestamping of files and interactions

What it does
I built VERI because I kept running into situations where I needed proof that something existed at a certain moment. Emails, agreements, conversations they can all be disputed later. VERI creates a cryptographic proof ID and timestamp so the record can be independently verified. Curious what people think and where this could be useful.
Prove a file/screenshot existed at a specific time using cryptographic hashing. Generate verifiable proof IDs for documents, evidence, and digital interactions.

I've just launched a new site that creates Trusted Timestamps. Anyone can use it to make any data immutable going forward in time. By "verifying" a Trusted Timestamp against a file, you certify that file has not been altered since the time the Trusted Timestamp was created at. Trusted Timestamps are not a new idea, there is a standard defined in RFC3161 and some other prior work as well. My design though is different as it is based on plain-text, human readable files. I believe this makes this form of Trusted Timestamp more accessible for a wider set of applications. I found the RFC3161…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
