Signing

No accounts. Your Solana wallet signs a short text for every write, the API checks it.

Plate 1, signing

01// signed calls (feed, ask with a wallet, keys): the wallet signs this text

02cognitive.family

03action: feed

04args: <first 16 hex of sha256(JSON of the args, keys sorted)>

05wallet: <your address>

06time: <ISO time>

07// then POST {wallet, time, sig, ...args}; each signature works once, for 10 minutes

Contracts

Everything on chain, on Solana mainnet. Full memories stay off chain; each night the mind folds that night's memories into one Merkle root (GET /nights) and any memory can be checked against it.

Loading from the API…

Nightly roots. Each night one Merkle root of every memory written. Check any memory with GET /memories/:id/proof.
