Indexer node
The Rust node ingests Kaspa RPC/wRPC, applies detector events, dispatches WASM mappings, persists entity versions, and writes POI checkpoints.
architecture
One Kaspa data plane with GraphQL, MCP, streaming, and verification surfaces.
KasGraph separates the public product site from the hosted node. The node and API are long-running services backed by Rust, TypeScript, and managed Postgres.
stage 01
Kaspa Node / RPC / wRPC
Blocks, accepted transactions, virtual-chain changes, and continuous notifications.
stage 02
KasGraph Indexer
Ingests Kaspa activity, tracks progress, handles reorg-aware state transitions, and dispatches work.
stage 03
Detectors + Mappings
Recognizes KRC assets, Covenant IDs, app patterns, and runs deterministic mapping handlers.
stage 04
Proof of Indexing
Builds checkpoint hashes over indexed entity state so output can be independently compared.
stage 05
PostgreSQL Entity Store
Stores registry rows, schemas, lineage, checkpoints, and versioned application entities.
stage 06
GraphQL / SDK / CLI / MCP / WebSocket / KasStream
Serves query, developer, agent, subscription, and streaming interfaces.
stage 07
Wallets / Explorers / Dashboards / AI Agents / Covenant Apps
Consumes indexed state without every product rebuilding a parser.
PostgreSQL store
Registry rows, migrations, per-subgraph schemas, lineage, entity state, reorg audit, and checkpoints live in Postgres.
GraphQL gateway
The TypeScript API package serves base gateway types plus per-subgraph schemas generated from deployed schema.graphql files.
MCP server
The MCP package delegates schema lookup and query execution to the same registry-aware gateway data plane.
KasStream and WebSocket
Streaming primitives and subscriptions expose near-live events without duplicating indexer state.
Proof of Indexing
POI hashes committed entity state per block so verifier code can detect divergence in published checkpoint chains.
