Boutique Digital Infrastructure

Nebulous Holdings LLC is a boutique digital-infrastructure company focused on high-availability validator operations and on-chain reliability engineering. We combine disciplined systems design, rigorous security practices, and automation-first operations to deliver uptime, slashing resistance, and clean, auditable performance for long-horizon digital-asset strategies.

What We Do

Comprehensive validator services designed for institutional reliability

Validator Operations

Design, deploy, and maintain execution & consensus clients on hardened bare-metal. Target high uptime and low missed-attestation rates while minimizing slashing risk.

Observability & Automation

End-to-end telemetry with Prometheus/Grafana, alerting pipelines, health checks, and Ansible-based builds for consistent, repeatable fleet management.

Resilience Engineering

Rolling upgrades, blue/green cutovers, image pinning, configuration drift control, and disaster-recovery runbooks.

Key Management

Offline key generation, sealed-secret workflows, role-based access, and strict least-privilege network segmentation.

Capacity Planning

Cost/yield modeling, server sizing, and scale-out roadmaps that prioritize reliability over headline throughput.

Current Footprint

Live validators on PulseChain with a near-term scale plan toward 100+ nodes, staged across multiple data-center regions.

How We Run

The Nebulous way: disciplined, automated, and resilient

Hardened Stack

  • Ubuntu LTS, containerized clients
  • Minimal host surface, signed/verified artifacts
  • Firewall policies that default-deny

Network Posture

  • Private mesh overlay for admin (e.g., WireGuard/Tailscale)
  • Locked management planes
  • Audited bastion patterns

Change Control

  • IaC-driven deployments, versioned configs
  • Maintenance windows and rollback plans
  • Tested in staging before production

Observability

  • Per-validator dashboards
  • SLA/SLO tracking, log retention
  • Post-incident reviews with corrective actions

Recovery

  • Documented RPO/RTO targets
  • Snapshot strategies, redundant bootstraps
  • Practice restores (not just backups)

Security & Compliance

  • Hardware isolation for keys, MFA everywhere
  • Non-custodial by design
  • Quarterly credential rotation

Principles We Live By

Discipline

Procedure over improvisation; repeatable wins beat lucky spikes.

Integrity

Transparent metrics, clear change histories, and no "black boxes."

Resilience

Assume failure; design graceful degradation and fast recovery.

Sovereignty

Keep control paths minimal, legible, and in your hands.
