CosmosMesh EnergiBridge - Toy Contract Sketch

Overview

• A minimal DSL sketch to describe LocalProblem, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, AuditLog, and a small Policy block.

DSL (pseudocode style):

LocalProblem { id: String, domain: String, assets: List } SharedVariables { forecasts: Dict<String, Float>, priors: Dict<String, Float>, version: Int } PlanDelta { delta: Any, timestamp: String, author: String, contract_id: String, signature: String } DualVariables { multipliers: Dict<String, Float> } PrivacyBudget { signal: String, budget: Float, expiry: String } AuditLog { entry: String, signer: String, timestamp: String, contract_id: String }

Policy {

• access: [roles],
• encryption: true,
• retention: 90 // days }

Usage notes

• These blocks are versioned and exchanged over a delta-sync protocol.
• The LocalProblem defines the per-asset planning task; SharedVariables and DualVariables carry the federated optimization signals; PlanDelta encodes the incremental changes with a cryptographic tag.
• PrivacyBudget and AuditLog enable governance and provenance tracking.

See the EnergiBridge demo for concrete Python representations that convert these DSL blocks into CatOpt-like IR structures.
