NexusFS

A verifiable offline-first distributed filesystem. NexusFS records writes as signed operations, derives a deterministic CRDT view, and uses Merkle proofs to support third-party verification.

01 · Overview

Storage whose history can be checked

Every accepted change becomes a signed operation in an append-only log. Replicas derive the same filesystem view through deterministic CRDT projection, while a Merkle accumulator supports inclusion checks and replay.

QUIC provides resumable peer transport for environments where devices disconnect, move between networks, or operate behind NAT.

02 · Research

Connecting replication, provenance, and audit

The research question is not only whether replicas converge, but whether another party can reconstruct why a specific state exists. Signed operations and deterministic replay make that history inspectable.

NexusFS is also intended as a storage substrate for evidence produced by Wardex and SafeDrop, where a receipt is useful only if its later custody can be checked.

Evidence boundary

NexusFS is explicitly a prototype. The verifier CLI, broader failure testing, and production hardening remain active work; the page does not present the design as production-proven.

Current focus: operation log, CRDT projection, Merkle accumulator, and verifier workflow.
