    Finding the balance between humans and machines has been the thread through my career. I always had a thing for AI and couldn't wait for it to actually deliver on what was promised. Now it does, and it's more important than ever that humans and machines keep working well together. AI makes creation trivial. Text, code, design, strategy, in seconds. But one thing AI does not create: independently verifiable proof of when something existed. Reproducing is now cheaper and easier than creating. Chronology becomes contestable at the moment it matters most. The universal problem was known. I…

    I made a new kind of Trusted Timestamp based on plaintext encoding▲5

    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…
