We know whether to trust the people we know. The longer we know someone, the more we understand how to trust them. Are they reliable -- can I count on them when I really need them? Or are they a fair-weather friend? Worse, are they someone to avoid entirely?
We develop this instinct naturally. It's built on history -- on repeated interactions over time.
But that behavioral continuity disappears the moment we step into cyberspace. AI agents, services, platforms, and yes, humans -- all operating across systems that know nothing about each other.
The same principle should apply online. The longer the history, the more diverse the platforms, the more an entity looks like a reliable friend -- and less like a stranger you have to take on faith.
Your friends go to Target and Dillard's and In-N-Out. They make deposits at the bank, trade securities, pay mortgages.
Does Bank of America know you got banned from an app today?
Does Bloomingdale's know about that bogus return you made to Amazon?
Does McDonald's know you just got verified on three new platforms this month?
The answer is no -- and they shouldn't. But what they should be able to do is query an independent service that records the actions an entity takes across all of them and get back history. Not judgment. Not a score. Just evidence -- the age of the history, the number of actions recorded, and across how many diverse platforms.
All of this needs to happen without exposing any personally identifiable information, through a neutral, central repository of recorded participation history. The internet is extraordinary at recording artifacts -- documents, websites, images. But it's terrible at remembering us. How we've contributed to our own historical record, whether that record is primarily positive or otherwise.
That continuity -- the kind we take for granted with the people we know -- should exist everywhere we participate. Not to surveil. Not to judge. Just to remember.
That's what MIR is.
MIR -- Memory Infrastructure Registry
Participation history. Nothing more. Nothing less.
