Was reading the SXT docs and got stuck on something less flashy than ZK proofs: who is actually allowed to write to a table.
When a developer creates a table with a signed CREATE TABLE statement, they can choose three write models: Public Write, where anyone can submit rows; Owner-Permissioned, where only the owner or an allowlist can; and User-Verified, where each row needs the user's ECDSA/ED25519 signature, with optional zkTLS or indexer verification.
I like that these arent treated as one-size-fits-all permissions. A public activity feed, a protocol-owned dataset and user-submitted records have different trust assumptions. Ownership can also be delegated through Biscuit authorization tokens, so control doesnt have to stay with the wallet that created the table.
I dont think that flexibility is a flaw by itself. But it puts a real decision in the developer's hands: the data layer can enforce the policy it was given, not rescue an app from choosing a permissive one. For tokenized assets or DeFi records, a bad write policy could matter long before anyone asks a clever SQL question.
I keep wondering whether builders will treat table permissions as core security design or just another setup field they click through. Which should be the default for sensitive datasets: owner-controlled writes or user-signed rows??
