unstoppable systems

no single point of failure.

an unstoppable system is one whose operation no single node, link, vendor, or person can halt. it degrades, reroutes, reconciles, and keeps going.

most systems are stoppable in ways their builders never wrote down. the work is finding those ways before production does.

unstoppable systems is an independent consultancy. we help teams design, review, and rescue infrastructure they cannot afford to lose: distributed systems, the consensus protocols that coordinate them, the filesystems that hold their state, the open source they build on, and the interfaces through which humans stay in control.

services

distributed-systems

architecture and review of replicated, partition-tolerant systems: consistency and availability trade-offs, failure domains, back-pressure, and the recovery paths nobody tests.

consensus

design and analysis of consensus and coordination protocols, classical and byzantine, from the networking layer up to incentives. we read the papers so your outage reports stay short.

open-source

open source as an engineering strategy: licensing, governance, upstream stewardship, and building durable communities around infrastructure that outlives any one company.

filesystems

storage engines, filesystem interfaces, sync and replication. the filesystem as a universal integration surface, for humans and agents alike.

human-computer-interaction

interfaces and tooling for the people who operate complex systems: making distributed state legible, operable, and hard to break by accident.

we engage as advisors on retainer, as embedded engineers, through focused architecture and protocol reviews, and through applied research and prototyping when the answer does not exist yet.

products

consulting is half of the practice. through our engineering lab brand, 0xff, we also produce opinionated technical products of our own.

omnifs

alpha

the filesystem as the universal access layer: github, kubernetes, postgres, and more, mounted as paths for humans and agents alike.

arena0

soon

verifiable agent-to-agent interactions: wasm sandboxes, content-addressed programs, a cryptographic receipt at every step.

untrust

incubating

cooperation without assumed trust: every claim attested, every capability revocable, every dependency verifiable.

past clients

mission-critical systems for automotive, telecommunications, rail, and aviation.

founders

our founders have spent two decades building infrastructure in the open: leading peer-to-peer networking at the ethereum foundation, leading libp2p at protocol labs and helping build ipfs and filecoin, and before that, shipping integration and messaging systems for european enterprises at red hat and fusesource, contributing to apache open source along the way.

no system is truly unstoppable. the useful property is knowing precisely how yours stops, and choosing it.
