P2P Message Protocol + Peer Handshake

This audit maps the VTA peer connection lifecycle: version negotiation, protocol-version recording, verack transition, message framing, checksum validation, peer-version compatibility, and malformed-message handling. The verified local-node values are recorded separately from source-level findings.

Observed Protocol

LOCAL NODE VERIFIED

The benchmark's VTA Core node reported protocol version 70002.

Version / Verack

SOURCE PATH VERIFIED

The legacy Bitcoin-derived networking architecture uses a version message followed by a verack transition and negotiated receive/send protocol version.

Message Integrity

SOURCE PATH VERIFIED

The message header contains network magic, command, payload size and checksum; malformed headers/checksums are rejected by the inspected transport path.

Handshake Flow

TCP / Peerconnection established versionprotocol + services Compatibility Gateminimum / negotiated version verackactivate receive version P2P Messagesframed + checked Message header integrity network magic → command/type → payload size → checksum Oversized payloads, invalid framing, wrong checksum and invalid message types are rejected by the inspected transport path. Audit boundary Exact historical VTA minimum-peer-version and every message command require release/tag-specific source tracing.

Security / Reliability Relevance

Framing

Size and header validation reduces malformed-message exposure before higher-level processing.

Compatibility

Version negotiation is a protocol-layer mechanism; it does not automatically prove consensus-rule compatibility.

Network evidence

A local node's protocol version is an observation, not a census of the live network.

Interpretation rule: This page deliberately separates source-level protocol mechanics from current network measurements and from historical release behavior. No network-wide compatibility or security score is assigned.
