UNOMP

Identification

UNOMP most commonly refers to Unified Node Open Mining Portal: an open‑source, Node.js–based Stratum mining pool “portal” and pool server stack used to run cryptocurrency mining pools (i.e., the web front-end plus the Stratum/pool back-end that miners connect to). (skypack.dev)

What the site at https://199.115.116.7:8925 most likely is

Given the label “miner-validator” and the name UNOMP, the endpoint 199.115.116.7:8925 is best interpreted as an instance (deployment) of UNOMP pool software exposed on a nonstandard HTTPS port (8925), rather than a distinct organization or individual named “UNOMP”. In other words, it is likely a mining-pool operator’s UNOMP web UI / API endpoint for monitoring pool stats and coordinating mining work distribution to connected miners. (skypack.dev)

Role clarification (miner vs. validator)

• Miner (PoW): UNOMP is designed for proof-of-work mining pools via Stratum, coordinating share submissions, difficulty, and payouts. (github.com)
• Validator (PoS): The term validator is generally used for proof-of-stake systems; UNOMP itself is not “validator software” in the PoS sense—it is mining-pool infrastructure. (skypack.dev)

Summary

UNOMP = mining-pool software stack (Unified Node Open Mining Portal). The referenced IP:port is therefore most plausibly a specific UNOMP-powered pool endpoint, not a separately identifiable public entity called “UNOMP.” (skypack.dev)
