On-Chain Module Map

Every piece of protocol behavior lives in a Cosmos SDK module under x/ in the virtengine repository. This page is the canonical index. Modules are grouped by function; each name links conceptually to the docs page that covers it in depth.

Marketplace & compute

Module	Purpose
x/deployment	Tenant deployments: the workload manifests and groups that orders are opened against.
x/market	The exchange core — orders, provider bids, and the leases formed when they match.
x/marketplace	Provider offerings catalog: published capacity listings that tenants and the HPC pipeline reference.
x/provider	Provider registry — on-chain identities, attributes, and endpoints for capacity operators.
x/resources	Resource type definitions and accounting shared across deployments and offerings.
x/hpc	High-performance computing: clusters, queues, job submission, scheduling decisions, and workload templates. See HPC Workloads.

Economics & payments

Module	Purpose
x/escrow	Custody of tenant funds backing leases; releases payment as usage settles. See Escrow & Settlement.
x/settlement	Converts signed usage records into billable line items, enforces the dispute window, and tracks reconciliation.
x/take	Marketplace settlement policy — proposed at 0% commission; validator transaction fees remain separate.
x/bme	Token burn/mint operations and VEID-led issuance mechanics. See Settlement Policy & Issuance.
x/issuancepolicy	Governance-controlled token issuance policies, including pause controls, applied via proposals.
x/staking	VirtEngine’s staking extensions — validator reward logic including VEID verification rewards.
x/delegation	Delegation records and lifecycle for token holders staking with validators.

Identity & trust

Module	Purpose
x/veid	The VEID identity layer: identity scopes, verification records, consent settings, zero-knowledge proof verification (x/veid/zk). See VEID Overview.
x/veidregistry	Registry of approved VEID verifier versions — upsert, approve, retire flows and validator readiness reporting.
x/mfa	Multi-factor authentication factors and policies for protocol accounts.
x/cert	TLS/mTLS certificates used to secure tenant↔provider communication.
x/roles	Role-based access control for privileged protocol operations.
x/review	Tenant reviews of providers — reputation input for provider selection.
x/audit	Third-party auditor attestations about providers. See Fraud, Audit & Oracles.
x/benchmark	Provider performance benchmarks recorded on-chain.
x/fraud	Fraud reporting and evaluation — flags anomalous usage, identity, and marketplace behavior.

Security & infrastructure

Module	Purpose
x/encryption	Encrypted payload envelopes and key fingerprints used by VEID and other confidential state. See Encryption & Enclaves.
x/enclave	Trusted execution environment (TEE/enclave) registration and attestation.
x/oracle	External data feeds (e.g., pricing) brought on-chain with validator-verified reports.
x/config	Chain-level configuration parameters managed through governance.
x/support	On-chain support ticketing and escalation workflows.

Note

Module APIs (messages, queries, events, parameters) are defined in each module’s types/ package in the repository. When docs and code disagree, the code and its tests are authoritative — see Clients & SDKs for how to explore them.
