something i was reading through last night when i was looking for a proper entry point in XAG and ETH and suddenly my mind runs to whitepaper of Sign in the TokenTable spec caught me off guard honestly 😂
the duplicate prevention mechanic is more interesting than it sounds on paper. when a government runs a benefits distribution, the obvious attack surface is the same person claiming twice under different wallet addresses. TokenTable closes that gap by linking distributions to verified identity attestations rather than wallet addresses
the wallet is just the delivery endpoint
the identity is the eligibility gate
what that means technically is that a recipient cant route around a distribution limit by generating a new wallet. the eligibility check runs against the identity layer, not the address layer. one verified identity, one claim, regardless of how many addresses that identity controls.
the part i keep turning over is what happens at the identity layer boundary. duplicate prevention is only as strong as the identity deduplication underneath it. if two verified identity records exist for the same person - through an enrollment error, a name change, or a legacy system migration gap - the protocol has no way to know
it prevents duplicate claims per identity record
not per human being.
airtight duplicate prevention that solves the core double-claim problem in government distributions - or a guarantee that holds precisely as long as the identity registry underneath it has no duplicates of its own?? 🤔
