Gravit Open Network

Epistemic Execution System (EES)

Gravit is a distributed, trace-preserving, adversarially resilient computation substrate for verifiable reasoning systems.

Gravit is not about making AI smarter. It is about making collective human–machine reasoning durable, traceable and accountable.

What changed in -01

Major updates from -00 (2026-07-20) → -01 (2026-07-21):

• Cost model C() formally defined: C_validation = k*COSE_Verify + fetch_trace + Merkle_Verify, C_manipulation = k'*DID_creation + k'*sign*(1/eta)^gamma, invariant C_manipulation > C_validation * 2.0
• GQRVP clarified: Canonical definition = "Gossip with Quadratic Reputation and Verifiable Proofs" (supersedes "Quantum-Ready" informal). MWU + Gossip.
• Security bound derived, not asserted: For gamma=1.5, eta=0.2, eps=0.1 → requires h > 0.7 honest weight (f < 0.3). Previous 67% Byzantine resilience in -00 retracted as imprecise.
• theta_critical: MUST 0.731 in -00 → RECOMMENDED 0.73 in -01, derived via ROC on 100 runs (0.728 ±0.015), range 0.70-0.80 allowed.
• Empirical validation made reproducible: traces/sybil-10x-g1.5.jsonl (100 runs × 30 claims = 3000 records), tools/verify_local.sh --trace sybil-10x-g1.5 --theta 0.73
• SCITT alignment: Added normative refs to draft-ietf-scitt-architecture (RFC 9943), RFC 9052 (COSE), W3C DID-Core, MWU, Gossip.

Core Principles

1. Triad Model

• Open Network (interaction layer) — Gateway, Coordinator
• Continuum (state evolution layer) — SCE
• Quantum (trace integrity layer) — Ω Trace Store

2. GQRVP (Gossip with Quadratic Reputation and Verifiable Proofs)

• eta = 0.2 (MWU learning rate)
• gamma = 1.5 (quadratic penalty)
• eps = 0.1 (gossip fault tolerance / exploration)
• Resilience: derived bound f < 0.3 weight Byzantine, up to f < 0.5 under 10x Sybil due to quadratic penalty — see specs/RFC/GQRVP-security.md and Section 5 of draft

3. History Keeper

Immutable temporal trace system ensuring full provenance.

• Append-Only, Content-Addressed, Hash-Linked (Merkle DAG)
• Formal-to-epistemic threshold: theta_critical RECOMMENDED 0.73 (calibrated, not fixed)

System Architecture

Gateway → Coordinator → SAIL → SCE → Trust Engine → Ω Trace Store

Core Endpoints (VCP-Compatible)

• POST /v1/claim — submit Claim
• GET /v1/claim/{claim_id} — retrieve with confidence + merkle_proof
• POST /v1/action/verify — verify Action against basis Claims (MUST reject if basis empty or min confidence < theta)
• GET /v1/trace/{trace_id} — immutable verification history (SCITT Transparent Statement equivalent)

All over HTTPS, application/json or application/cbor, COSE/JOSE signatures did:web / did:jwk for -01.

Empirical Traces

This repo contains reproducible datasets referenced in [TRACE-DATASET] of draft -01.

Location: traces/

• sybil-10x-g1.5.jsonl — 3000 records (1500 honest, 1500 sybil), params eta=0.2 gamma=1.5 eps=0.1 sybil_factor=10 theta=0.73
  • Canonical URL: https://github.com/GravitOpenNetwork/gravitnet/blob/main/traces/sybil-10x-g1.5.jsonl
  • Commit pinned for -01: 7755f53 (data) + 9f3e5d1 (README) — to be formally pinned in -02
  • Stats in this instance: honest mean 0.839 passes 1401/1500 @0.73, sybil mean 0.412 passes 6/1500

Reproduction:

./tools/verify_local.sh --trace sybil-10x-g1.5 --theta 0.73

See traces/README.md for full schema and Python verification.
