I've seen things you people wouldn't believe. Hard forks burning off the shoulder of 250 chains. I watched signing ceremonies glitter in the dark near the KMS gate. Fifty million in keys, and not one of them lost. All those moments will be lost in time, like tears in rain… unless they're signed, hashed, and anchored on-chain.
Q You find a private key lying in the
desert sand. What do you do?
A I don't pick it up. I build a vault
around it, and give the vault two
more signers.
Q An AI agent asks for signing
authority. Your response?
A Yes. Out of the box it signs nothing.
The policy is plain code, with no
model in it. The model can propose.
It never decides.
Q A system is about to fail at 3 a.m.
Who do you want on call?
A Agents. They don't sleep, they
read the runbook every time, and
they wake a human before they
touch the keys.
Q Describe in single words only the
good things that come into your
mind about your work.
A Keys. Thresholds. Proofs. Rain.
── RESULT: inconclusive.
More human than human.
