Smart Contract Stack

AI-Scored, Quantum-Safe Contracts

QP contracts are authored in natural language, compiled to deterministic bytecode, and wrapped with validator-sharded 2FA. External calls are sandboxed and scored by an AI risk engine so counterparties can decide how much uncertainty to accept.

How the Model Works

Each phase is enforced at protocol level: author in plain English or Solidity, score every non-deterministic edge, then finalize with validator-held 2FA shards.

1

Author & Generate

Teams describe intent in natural language. The compiler emits bytecode plus human-readable clauses, invariants, and tests. Guardrails block unsafe patterns and surface missing checks before deployment.

2

Score & Simulate

The AI oracle simulates calls to external APIs, price feeds, and off-chain software. It publishes a safety grade per route (A–F) with rationale, traceability, and fallback actions.

3

Enforce & Finalize

Runtime execution remains deterministic. Non-deterministic inputs must attach their score and provenance. Validators enforce quorum-signed 2FA; counterparties can reject interactions below their risk appetite.

Architecture Pillars

Deterministic Core

Bytecode with Guardrails

Contracts compile to a deterministic VM. Static analysis ensures bounded loops, explicit error handling, and consistent state updates before bytecode is accepted.

External Data

Scored Oracle Routes

Every API/market read is routed through a scoring service that logs provider, timestamp, variance, and Monte Carlo stress tests. Trusted sources (e.g., NYSE feeds, CoinGecko, government open-data APIs) inherit higher baseline confidence; riskier endpoints get throttled or rejected. Scores become part of the transaction metadata.

Post-Quantum Posture

Validator-Sharded 2FA

Even if a signing key leaks, the transaction cannot clear without validator quorum approval. Shards rotate; compromised keys trigger rapid shard re-issuance and circuit-breakers.

Safety Grades

Grades are attached to calls, cached on-chain, and consumable by wallets, dApps, and counterparties.

GradeMeaningCommon Triggers
ADeterministic or redundant data sources with historical stabilityOn-chain price feeds, multi-API quorum with agreement, deterministic math paths
BMinor variance observed; mitigations in placeSingle API with signed attestations, cached responses, time-bound windows
CNon-deterministic input accepted with guardrailsVolatile market reads, user-supplied params with caps, simulation divergence <5%
DHigh variance; consumer must opt-inIlliquid feeds, large slippage tolerance, external compute with limited proofs
FRejectedUnverifiable source, tamper signals, timeout or replay risk detected

Our source registry ranks inherently trustworthy venues—major exchanges (e.g., NYSE), curated crypto aggregators (e.g., CoinGecko), and government sites—so high-signal feeds start with higher confidence while fringe or unverifiable sources get downgraded by default.

Developer Workflow

Tooling

  • Natural-language contract authoring with inline linting and invariant suggestions.
  • One-click test generation plus fuzzing against probabilistic inputs.
  • Risk-grade preview before deployment; publish grade + rationale alongside ABI.

Operational Controls

  • Auto circuit-breakers on score downgrade or oracle divergence.
  • Timelocked upgrades with validator co-sign and public rollback plans.
  • On-chain changelog that links human-readable clauses to bytecode diffs.

Run-Time Guarantees

Deterministic Execution

All state transitions are repeatable; probabilistic branches must attach the oracle decision and score so nodes can reproduce and audit.

Chain of Custody

Each external call stores provider, latency, variance band, and signer. Counterparties can refuse to interact if custody is missing.

2FA Finalization

Validator shards co-sign transactions and contract deployments. Shard rotation policy prevents long-tail accumulation of risk.

Assets: Tokens vs NFTs

Fungible (Tokens)

  • Standardized mint/burn with circuit-breakers on score downgrades.
  • Router API exposes `price`, `quote`, `swap`, and `state` for bonded-curve pairs.
  • Supply changes are co-signed by validator shards; treasury moves require 2FA quorum.

Non-Fungible (NFTs)

  • Immutable media links with optional content hashing for tamper checks.
  • Royalty + split payouts are scored when using external price/metadata feeds.
  • Transfers can require shard concurrence for high-value collections.

API & Publishing Overview

Core APIs

  • Node REST: `/dex/state`, `/dex/quote`, `/dex/lastPrice`, `/support/message`.
  • Contract deploy: submit ABI + bytecode + human-readable clauses for grading.
  • Event hooks: webhooks or SSE for grade changes, oracle divergence, and breaker trips.

Publishing Flow

  1. Author in English or Solidity; generate guarded bytecode and tests.
  2. Attach risk sources (oracles, caps, invariants); request a grade.
  3. Validator-sharded 2FA co-signs the deploy; publish ABI + grade.
  4. List token/NFT in router (if fungible) or registry (if NFT); expose docs in the explorer.
