7aychain Terminology
Key terms, modules, and concepts in the 7aychain Proof of Presence protocol — from witness circles to ZK circuits.
A
Autonomous Detection
An on-chain module that automatically flags suspicious patterns in presence verifications. Detects coordinated bot behavior, spoofed timing, and statistical outliers without manual reports.
B
Boomerang Proof
A cryptographic proof that someone returned to a previously verified location. Proves consistent presence patterns over time without revealing the location — enabling reputation without surveillance.
C
Circuit Registry
The on-chain registry of ZK circuits available for proof generation and verification. Manages circuit versions, proof mode migration, and verifier configurations.
Commit-Reveal Scheme
A two-phase anti-tampering protocol: first commit a hash of your presence data (hiding it), then reveal the actual data in a later phase. Prevents front-running and ensures fair ordering.
D
Device Scanner
A module for registering devices that participate in presence verification. Manages device identity, verification capability, and revocation — ensuring only authorized hardware contributes.
Dispute Resolution
The on-chain process for challenging presence verifications. Disputants submit cryptographic evidence, validators vote, and the protocol enforces outcomes — including slashing for dishonest verifiers.
E
Epoch
A fixed time window during which presence declarations and verifications occur. Epochs structure the protocol lifecycle, determine validator rotation, and isolate verification rounds.
G
Groth16
A zero-knowledge proof system used by 7aychain for compact, non-interactive presence proofs. Delivers constant-size proofs with fast on-chain verification — critical for scalable privacy.
L
Laud Networks CLI
A Python-based terminal interface for interacting with all 16 7aychain modules. Supports presence declaration, validator management, ZK proofs, governance, vaults, and more.
Lifecycle
The six-state machine governing a presence declaration: Declare, Commit, Reveal, Attest, Triangulate, and Finalize. Each transition is enforced by the protocol.
M
Multilateration
A positioning technique that estimates physical location from network timing measurements taken at multiple validator points. The core triangulation algorithm powering witness circles.
O
Octopus Groups
Organizational units that group validators and participants for coordinated presence operations. Groups can define shared governance rules and collective verification thresholds.
P
Position Bound Token (PBT)
A token minted when presence is verified. PBTs bind verification claims to specific positions and time windows, serving as proof-of-presence credentials — without revealing exact locations.
Presence Lifecycle
The six-phase protocol flow: Declare (announce intent), Commit (submit hash), Reveal (disclose data), Attest (validators measure), Triangulate (compute position), Finalize (quorum seal).
Proof of Presence (PoP)
7aychain's consensus mechanism. Validators form witness circles and verify physical presence through network timing measurement — no GPS, no biometrics, no external hardware. Bot-proof by design.
Q
Quorum Consensus
The validator agreement threshold required to finalize a presence verification. A declaration is only finalized when enough validators in the witness circle converge on a position estimate.
S
Semantic Links
On-chain relationships between entities (people, locations, organizations) forming a trust graph. Enable contextual verification and reputation scoring based on verified presence history.
Shamir Secret Sharing
A cryptographic scheme used in 7aychain's vault system to split sensitive data across multiple parties. No single party holds enough to reconstruct the secret — enabling secure recovery without central custody.
SNARK
Succinct Non-interactive Argument of Knowledge. A zero-knowledge proof type used by 7aychain for compact, efficiently verifiable presence proofs.
Storage Layer
A module providing on-chain and off-chain data storage for presence proofs, verification records, and protocol state. Supports pinning, retrieval, and data availability guarantees.
T
Triangulation
The process by which validators estimate physical position using network timing measurements from multiple reference points. Combines multilateration with position algorithms for high-confidence verification.
V
Validator
A node operator who stakes $7AY to participate in consensus, presence verification, and witness circle triangulation. Earns rewards for honest behavior; faces slashing for dishonesty.
Vault
A secure on-chain storage system using Shamir secret sharing for distributed key management. Enables data recovery and controlled sharing — without central custody.
W
Witness Circle
A randomly selected group of validators assigned to verify a presence claim. Circle members independently measure timing and collectively confirm the person's physical position.
Z
ZK Circuit
A zero-knowledge computation circuit that generates proofs verifying presence without revealing exact location data. 7aychain uses Groth16 circuits with an on-chain registry.
