Blockchain NodeOps
Defensive utilities for administrators of blockchain nodes on LinuxBlockchain NodeOps
Introduction
Blockchain NodeOps is a category of defensive utilities for administrators who run blockchain nodes on Linux: checking the health of JSON-RPC endpoints, estimating hardware before buying a server, generating a read-only preflight script for a new node, and analysing validator logs for the failure patterns that cost uptime and penalties.
The four tools follow the same rules as the rest of OthoTools: deterministic checks, honest limits, official references and local processing. Nothing you paste — endpoint URLs, sizing inputs, server reports or logs — is uploaded, stored or sent anywhere.
Objective
- RPC Health Checker — probe Ethereum, Solana and Cosmos endpoints for latency, sync state, height, chain ID and peers, and compare two endpoints of the same network.
- Blockchain Node Sizing Calculator — estimate CPU, RAM and storage for Ethereum, Bitcoin, Solana, Cosmos and Polkadot nodes across pruned, full, archive, RPC and validator profiles.
- Linux Node Preflight — generate a read-only bash script that inventories a server before a node rollout, then analyse the report locally.
- Validator Log Analyser — detect OOM, full disks, missed slots, duplicate validator keys, slashing risk, clock drift and more in pasted node logs.
Risks
- Endpoints are probed directly from the browser; there is no RPC proxy on the server and no arbitrary URL is ever sent to the OthoTools backend.
- Sizing inputs, preflight reports and logs are processed locally. Sensitive values (IPs, hostnames, paths, tokens, possible secrets) are masked before display and never echoed in full.
- The preflight script is diagnostic only: it installs nothing, changes no configuration and sends nothing to the network except a TCP reachability probe.

FAQ
Do these tools touch my node or my keys?
No. The tools run in your browser. The only thing that touches your server is the preflight script you choose to run, and it is read-only. Endpoint checks are browser-to-endpoint requests; logs and reports stay on your device.
Is any of this financial advice?
No. The tools estimate hardware and detect operational problems. They never calculate profit, ROI or coin appreciation, never recommend buying tokens and never promise validator eligibility.
Can these tools guarantee my validator will not be slashed?
No. The log analyser detects patterns that often precede or indicate problems; it cannot prevent them. Running a validator requires following the chain's official operations guidance and monitoring stack.
