Network Version

Overview

Network version can refer to client release compatibility, peer protocol negotiation, address prefixes, transaction formats, or activated consensus rules. The exact field must be interpreted within its software and protocol context. Different client versions can remain consensus-compatible while exposing different RPC behavior. After an upgrade, outdated nodes may disconnect, stop at activation, or follow an incompatible fork. Version strings alone do not prove that required rules are active.

Operators should inventory client, database, signer, API, and protocol versions and compare them with the network’s upgrade schedule. Applications need compatibility tests and clear minimum versions. Incident logs should preserve version information so divergent validation or parsing can be reproduced later.

Unknown versions, ambiguous aliases, unsupported fields, duplicate records, and stale configurations should fail into review rather than being silently mapped to a convenient default. Inputs to Network Version need explicit validation and deterministic failure behavior. Changes to Network Version should pass automated tests against known network identifiers, contracts, encodings, and expected outputs. Rollout needs environment separation, change approval, rollback, and historical traceability so past transactions can be interpreted using the configuration active at that time.

This evidence helps distinguish incorrect configuration from an upstream node, protocol, or business-logic failure. Operational logs for Network Version should record the version, caller, resolved value, and downstream action without exposing secrets. Network Version should be maintained through one versioned source of truth that defines identifiers, schemas, allowed values, ownership, and deployment scope. Human-readable labels are not sufficient when different chains, environments, or providers reuse similar names.
