The Raw Signal
An Endpoint is the atomic unit of chain connection.
It represents the physical interface to a blockchain node—the raw signal that Backpac perpetually vets before it is promoted to the Orchestration Engine.
Sovereign vs. Managed Performance
Backpac supports two fundamental models for signal acquisition:
Sovereign Infrastructure (BYO)
Integrate any compatible RPC gateway as a private, sovereign endpoint. This enables complete control over your provider architecture (Alchemy, Infura, or self-hosted).
- Sovereignty: Absolute control over provider relationships and custom header mandates.
- Isolation: Unified access for authenticated infrastructure.
Managed High-Fidelity (DIN)
Leverage the Decentralized Infrastructure Network (DIN) for pre-vetted, high-performance signal paths.
- Dynamic Resolution: Automatic endpoint discovery and failover across the DIN cluster.
- Latency Optimization: Optimized routing through Backpac's institutional backbone.
Direct Orchestration
While most traffic is governed by Reliability Pools, Backpac supports Direct Orchestration for specific technical overrides.
Direct Node Assignment
You can pin an Institutional Entry Point to a specific endpoint, bypassing the load balancer to route 100% of traffic to a single infrastructure provider. This is the requirement for debugging state-specific consistency or forensic isolation.
Active Verification
Backpac does not trust upstream providers. The Monitor Service executes sub-second verification loops on every active endpoint:
- Liveness Verification: Direct HTTP 200 state checks.
- Telemetry Profiling: Real-time and historical latency EMA tracking.
- Chain Freshness: Strict verification of slot/block drift from the network tip.
Endpoints that fail verification are immediately pruned from the orchestration logic to protect the Unified SLA.
Metadata Enrichment
Endpoints can be tagged with operational metadata to influence orchestration:
- Regional Anchoring: Geographic tagging (GCP, AWS, Global) to enforce physical proximity.
- Routing Attributes: Custom key-value pairs used by Orchestrator Laws to steer traffic based on provider-specific logic.
The endpoint is the wire. The logic is the current.
