The infrastructure
your validator runs on.

Chef Node operates EarthNodes on enterprise hardware we own and run end-to-end: Supermicro A+ servers, AMD EPYC compute, dual ISP uplinks, sentry-gated validators, ZFS storage, battery-backed power, and no public-cloud custody.

A five-layer network segmented like a bank's.

North-south traffic enters through a redundant edge, passes IDS/IPS inspection, aggregates over 25-Gigabit SFP28 uplinks, and lands on isolated VLANs at the distribution layer. Two independent ISP paths keep the node reachable when one route disappears.

Design principles

  1. 01Two ISPs, different last-mile technologies

    One outage, one fiber cut, or one provider change window does not take the node offline.

  2. 02No validator port exposed to the internet

    Validators are not directly routable from the public network. Sentries are the only north-south gateway.

  3. 03MAC-level allowlist on Layer 2

    External physical devices are blocked by default. Anything new must be pre-registered.

  4. 04Application-layer load balancer, single port

    All traffic is gated through one port. Internal services resolve through private DNS.

  5. 05Public identity abstracted behind proxies

    The validator's private network identity is not advertised directly to internet scanners.

Supermicro A+ AS-1125HS-TNR.

The bare-metal platform Tier 1, Tier 2, and Tier 3 EarthNodes run on. Dual 96-core EPYC Turin, 1.1 TB DDR5 ECC, enterprise Gen4 NVMe, and independent network controllers in a single chassis with headroom for validators, sentries, AI inference VaaS, and storage services.

Roadmap Next chassis qualifies PCIe Gen5 enterprise NVMe without changing the ZFS topology.

Three ZFS pools. One backup spine.

The NVMe array is partitioned into three high-availability ZFS pools: one for the EarthNode itself, one for snapshots and active backups, and one for value-added services. Every pool snapshots to a separate bare-metal backup server.

Six points of failure, each one doubled.

Uptime is not a number we publish. It is a list of decisions made before a failure happens. Field-replaceable components, storage paths, network paths, and power inputs are designed with mirrored or redundant partners where the platform supports it.

~

Dual redundant PSUs

Hot-swappable power supplies keep the host online through a single PSU replacement or PSU fault.

[][]

Dual CPUs

Two EPYC 9655 Turin sockets provide compute headroom. Host-level faults are covered by backup, restore, and failover runbooks.

==

Storage path resilience

ZFS redundancy, mirrored boot media, snapshots, and the backup server prevent one storage fault from becoming one recovery path.

--

Quadruple network paths

Two NICs, two technologies, and four physical links keep the node talking.

[]

RAID-1 boot drives

Dual M.2 NVMe boot drives are mirrored so a boot-disk fault can be isolated without data loss.

UPS

Mission-critical UPS

Smart UPS on primary and backup server gives the operator time to ride through or cleanly handle power events.

The validator is not directly routable.

Public traffic terminates before it reaches the validator host. It hits IDS/IPS at the edge, traverses isolated VLANs, passes through a single-port load balancer, and is relayed by a sentry on a private network.

Layer 01

Perimeter · IDS / IPS

UDM-PRO SE · 3.5+ Gbps inspection

Every packet entering the network is inspected for known attack signatures and behavioral anomalies before it reaches a switch.

Layer 02

VLAN isolation · honey-pot per VLAN

L3 switching at aggregation + distribution

Network segments are isolated by VLAN, and each VLAN ships with a honey-pot used to detect lateral movement.

Layer 03

MAC allowlist · L2

Pre-registered devices only

Unknown physical devices cannot communicate on the network even if connected directly to a switch port.

Layer 04

Single-port load balancer

Application layer · private DNS

North-south traffic enters through one software-controlled gate. Internal services are not publicly addressable.

Layer 05

Sentry-gated validator

Validator on a private isolated network

Only the sentry talks to the validator over a single private port. The EarthNode is not directly advertised or routed publicly.

Layer 06

Encryption · proxies · zero-trust admin

End-to-end · self-hosted ZT plane

Administrative access flows through a self-hosted zero-trust platform that controls and monitors every connection.

Layer 07

OS hardening · 2FA · fail2ban

Root forbidden · brute-force prevention

Root login is forbidden, two-factor authentication is required, and fail2ban shuts brute-force attempts down at source.

Third-party penetration tested.

Independent penetration testing is scoped against the exposed network, access controls, and administrative plane. Current scope, cadence, and remediation status can be shared during technical diligence.

Type-1 hypervisor. One VM per node.

Every EarthNode lives inside its own virtual machine on a Type-1 hypervisor, not a container and not a shared OS. Process isolation is enforced underneath the guest operating system.

Why Type-1, not containers.

Containers share a kernel. A bug in the kernel or a misconfigured namespace becomes everyone's problem. A Type-1 hypervisor gives every VM its own kernel and isolates it at the hardware level.

Practically, that means an EarthNode, sentry, AI inference VaaS, and storage VaaS can run on the same chassis while materially reducing cross-service risk.

Whole-site power, battery-backed.

The validator is buffered from grid events. An EG4 GridBOSS sits at service entrance, a FlexBOSS21 hybrid inverter handles transfer in milliseconds, and a 14.3 kWh LiFePO4 wall battery carries the load.

Design intent Solid lines are power flow. The smart-load port keeps UPS and network-control gear alive while the inverter and battery carry the validator stack.

The proof layer, not just the stack.

For technical reviews, the infrastructure conversation should include operational evidence, not only hardware diagrams. These are the controls we expect sophisticated operators to ask about.
