vOps

vOps is a Cosmos validator operations platform. It ships two binaries:

• vOps — dashboard for log analysis, threat intelligence, OSINT, and fleet management (formerly vLog, renamed in v1.4.0).
• vProx — production-grade reverse proxy that routes RPC, REST, gRPC, gRPC-Web, and WebSocket traffic to backend nodes, with per-chain configuration, IP-based rate limiting, geo enrichment, Prometheus metrics, and structured logging.

Quick Start

Prerequisites

Tool	Version	Notes
Go	1.25+	See go.mod
make	GNU make	Build automation
git	Any	Clone the repo
apache2-utils	Any	htpasswd for vOps auth (optional)

Install

git clone https://github.com/vNodesV/vOps.git
cd vOps
make install

make install validates Go, creates ~/.vOps/ directories, decompresses the GeoIP database, installs sample configs, creates .env, and builds both binaries to $GOPATH/bin/.

GeoIP database

The geo database is installed automatically by make install (skipped if already present). To force a re-extract:

gunzip -c assets/geo/ip2location.mmdb.gz >~/.vOps/data/geolocation/ip2location.mmdb

Configure a chain

cp ~/.vOps/config/chains/chain.sample.toml ~/.vOps/config/chains/my-chain.toml
$EDITOR~/.vOps/config/chains/my-chain.toml

vOps Dashboard

A React 18 + TypeScript SPA for log analysis, threat intel, and fleet operations:

• IP Account CRM: per-IP profiles with request history, block/unblock, notes, and threat badges
• Threat Intelligence: AbuseIPDB v2 + VirusTotal v3 + Shodan — composite score 0–100 (parallel, ~10 s)
• OSINT engine: concurrent DNS, port scan, org/geo, protocol probe, Cosmos RPC (~5 s)
• InvestigateModal: two-phase SSE investigation with animated progress bars; Org / Requests / Rate Limits / Score in the modal header; table order preserved after scan
• Scan badge: IntelUpdatedAt timestamp displayed per-row — see at a glance which IPs have been investigated
• UFW Sync: syncs blocked IPs to UFW rules; optional sudo password popup
• Dashboard Servers panel(v1.4.5): live VM metric cards (OS, CPU / Memory / Disk, Load, pending updates, per-VM upgrade SSE stream)
• Fleet page(v1.4.5): live server metrics section + registered chains + deployment history
• Multi-location endpoint probing: local + 🇨🇦 Canada + 🌍 worldwide via check-host.net
• Dashboard authentication: bcrypt password hashing, HMAC-SHA256 session tokens (24 h TTL)
• Config Wizard: 7-step browser wizard (vops config --web) for full vOps + vProx setup

Run

make install # first-time setup: builds + installs vOps + vProx, config, services
make upgrade # later: rebuild + redeploy both binaries after a code change
vops start # foreground server (default: :8889)
vops start -d # start as background service
vops stop # stop vOps service
vops restart # restart vOps service
vops status # show status and database stats
vops ingest # one-shot archive ingest
vops -a # list IP accounts as JSON
vops -t # list flagged IPs (score ≥ 50)
vops vprox start # start the embedded vProx proxy

For full setup including authentication, API key configuration, and block/unblock, see the Installing vOps section in INSTALLATION.md.

vProx Reverse Proxy

Proxy & Routing

• Per-chain TOML configuration with host-header matching
• Path-based routing (/rpc, /rest, /grpc, /grpc-web, /api) and subdomain routing (rpc.<host>, api.<host>)
• WebSocket proxying with configurable idle timeout and max lifetime
• HTML banner injection and RPC address masking

Security & Rate Limiting

• Per-IP token bucket rate limiting with auto-quarantine
• Trusted proxy CIDR configuration (XFF header trust scoping)
• WebSocket origin allowlist (same-origin by default)
• JSONL rate-limit audit log

Observability

• Prometheus metrics endpoint (/metrics) — 8 metrics covering requests, connections, latency, errors, rate limits, geo cache, and backups
• Health check endpoint (/healthz) — JSON status with uptime; returns 503 on subsystem failure
• pprof debug server on separate port (VPROX_DEBUG=1 only)
• Structured dual-sink logging (stdout + file) with typed request IDs (RPC{hex}, API{hex})

Geo Enrichment

• IP2Location MMDB lookup for country and ASN per request
• Bundled database (assets/geo/ip2location.mmdb.gz) — no external download required
• In-memory cache with periodic refresh

Backup & Operations

• Automated log backup with TOML-configured scheduling and multi-file archive support
• Service management: start -d, stop, restart with systemd integration
• Passwordless sudoers rule for daemon control

Run

vops vprox start # foreground, listens on :3000 by default
vops vprox start -d # start as systemd service (daemon)
vops vprox stop # stop the service
vops vprox restart # restart the service
vops vprox status # show service state and basic stats
vops vprox view # tail vProx service logs

The proxy is also buildable as its own binary (make build-vprox, go run ./cmd/vprox) for local development and diagnostics — see the advanced standalone reference in CLI_FLAGS_GUIDE.md for its full flag set (--validate, --with-vops, completion, etc.).

Architecture

vProx follows a modular internal architecture with clearly separated concerns:

Package	Responsibility
cmd/vprox	CLI entrypoint, flag parsing, server lifecycle
internal/config	Chain and port TOML loading, validation
internal/counter	Per-IP access counter with disk persistence
internal/logging	Structured logging, typed request IDs (RPC{hex}, API{hex})
internal/metrics	Prometheus metric registration and recording helpers
internal/backup	Scheduled log archival with tar.gz compression
internal/geo	MMDB geo lookup with in-memory cache
internal/limit	Token bucket rate limiter with auto-quarantine
internal/ws	WebSocket proxy with idle/lifetime timers

Data flow: Incoming request → host-header match → chain config lookup → rate limiter → geo enrichment → reverse proxy → structured log + metrics.

For the full module-by-module reference, see MODULES.md.

CI/CD

• golangci-lint with 14 linters enforced on every PR
• Test coverage gate (≥60%)
• Automated release workflow: cross-compilation for linux/darwin × amd64/arm64

Configuration

vProx and vOps use TOML configuration files stored under ~/.vOps/:

File	Purpose
config/ports.toml	Default service ports for all chains; vops_url for integrated mode
config/chains/*.toml	Per-chain routing, services, and feature flags
config/chains/*.sample	Identity-only chain samples (chain_id, network_type, tree_name)
config/backup/backup.toml	Backup automation schedule and settings
config/vops/vops.toml	vOps server settings, auth, intel API keys
.env	Environment variables (rate limits, geo paths, server address)

Override the config base path:

export VOPS_HOME=/opt/vops
# or
vops --home /opt/vops

For the complete CLI flag reference, see CLI_FLAGS_GUIDE.md.

Security

• Run vProx behind a TLS-terminating reverse proxy (nginx, Cloudflare).
• Set trusted_proxies in chain config to restrict X-Forwarded-For trust to known CIDR ranges.
• Keep vOps's bind_address set to 127.0.0.1 (the default).
• Rotate API keys regularly.

To report a vulnerability, see SECURITY.md.
