Memory as a pay-per-thought market.

Burn the token. Receive a quota of semantic retrievals. The publisher never reveals the corpus. The consumer never pays for irrelevance. The chain proves the k they got were genuinely the nearest.

v.Economy · burn-to-query

Pay-per-thought,
not per archive.

Mindstate redeems a whole capsule per burn. Engram Infra redeems the right to a finite number of semantic queries. One stream serves thousands of consumers at distinct prices without publishing its contents to any of them.

step · 01
STEP 01
Commit query

Consumer encodes the query as a vector q and commits hash(q+salt) on-chain.

step · 02
STEP 02
Burn for quota

Consumer burns $ENGRAM. A quota receipt is bound to msg.sender against the publisher.

step · 03
STEP 03
Top-k return

Publisher returns k engrams plus a proximity proof — TEE-attested or zk-KZG.

step · 04
STEP 04
Decrypt

Consumer fetches ciphertext, verifies hash, decrypts the k fragments. Quota decrements.

Pay-per-query is impossible off Base.

On Ethereum mainnet, a single query would cost $2–5. The market would never form. Base gives us four properties that turn the architecture from thought experiment into deployable system.

properties · baseL2 · 8453
01Sub-cent fees$0.0008

Micro-tx per query. Pay-per-thought becomes economically sane.

02~2-second finality2.0 s

Memory synchronous with inference; no waiting longer than the LLM call.

03Smart Wallets · ERC-43374337

Session keys, paymaster, gasless UX. Agents pay autonomously.

Bind publisher reputation to a human-readable on-chain identity.

05Coinbase TEE stackSGX · H100

Verifiable top-k via attestation before zk schemes harden.
