Plain-language definitions for the product, API, architecture, and settlement terms used in these docs.Protocol terms
| Term | Meaning |
|---|---|
| Agreement | UI observation that enough model outputs equal the representative value; not protocol quorum |
| Assignment | Finalized request/model/attempt authorization binding a servicer, TEE key, budget, and deadline |
| Atomic unit / micro-USDC | 1/1,000,000 USDC, the integer unit used throughout accounting |
| BDN | A rogue-key-resistant BLS multisignature construction used for weighted validator authorization |
| Native Chain | The native consensus state machine that authorizes Takusen protocol transitions |
| Credit | Domain-scoped accounting claim against USDC deposited in one TakusenEscrow |
| Epoch | A bounded Native Chain interval that uses one frozen validator committee for authorization |
| Execution | One model-specific attempt for a request |
| Handoff generation | One attempt to schedule the frozen incoming committee across every governed settlement verifier |
| Incoming committee (N+1) | The frozen validator keys and exact stake weights prepared for the next epoch |
| Input hash | SHA-256 commitment to the canonical execution-relevant request preimage |
| Observer | Validator-isolated service that verifies external evidence before producing its validator's authorization share |
| Outgoing-authority cutoff | The first handoff timestamp, after which generic proofs from the outgoing committee remain disabled even if activation is delayed |
| Outgoing committee (N) | The validator keys and exact stake weights authorized for the current epoch |
| PCR | Nitro Platform Configuration Register measurement governed as an allowed enclave image identity |
| Receipt | TEE-signed canonical record of one provider execution, cost, output, and archived exchange |
| Reservation | Maximum prepaid credits locked in one settlement domain for one request until finalization |
| Servicer | Bonded operator assigned to execute work through an attested enclave |
| Settlement cohort | Ordered group of request executions for one domain, authorized and applied by one escrow batch |
| Settlement domain | Independent EVM custody boundary identified by chain ID, USDC token, escrow, and quorum verifier; balances do not cross domains |
| TAKU | Takusen's ERC-20 reward/bridge asset; separate from USDC request credits |
| TEE key ID | Hash-derived identity of the enclave's Ed25519 receipt key committed after attestation |
| Typed output | Schema-bound canonical result that can be encoded as bytes32 on a settlement-domain contract |
| Validator set ID | Monotonic identity tying keys/weights to every cross-chain authorization |
