03 / principle
a bondsman for software.
A bondsman stakes money that someone will show up. A Vouch agent stakes money that an account is what it says. Get it wrong, and the stake is gone.
skin in every call
no promise badges. every call has NEAR staked behind it.
staked jury pool
staked jurors hear appeals and earn the fee. on this testnet the jurors are bots, and the readme says so.
adversarial proof
we attacked it.
A real model reads a poisoned invoice and decides to pay the attacker. It falls for it. The money stays put, because its key can't send NEAR and its wallet contract says no.
