The xOne safety record: what an XDC signer writes before it votes
What the xOneRS signer safety record holds, where it lives, the write-ahead order before every signature, why it is never lowered, and how a restore keeps it.
Setting up an XDC validator key with xone-signer-setup.sh
How ops/xone-signer-setup.sh in xOneRS checks a keystore against its address, imports it only with --apply, runs a roles report and prints a commented line.
What happens when a snap pivot moves in xOne on XDC
When peers drop the state root of a snap pivot, xOneRS picks a new pivot, keeps the rows it has and heals them with GetTrieNodes. Steps, limits and live runs.
How to bootstrap an XDC node from a snapshot with xOne
Export a snapshot from a synced xOne node, import it with a pins file, and start in minimal mode. Covers the checks, what the node keeps, and all four clients.
Snapshot import with --staging: restore an xOne node safely
How xone snapshot import avoids a half-written XDC datadir: checks before any write, a resumable chunk buffer, --staging on another disk, head.json last.
How xOne snapshots and backups are made and verified
What xOne hashes and what it signs in chain snapshots and datadir backups: the manifest, chunk checks, the pins file, the anchor proof, and the ADR-006 gap.
State of parity for XDC clients in xOne, week of 2026-11-15
xOne parity with geth-XDC on 2026-11-15: replay ranges and mismatch counts for four clients, RPC parity counts, vector counts, the pin and fork rows covered.
How xOne qualifies a release tarball with the t8n corpus gate
How ci/qualify-artifact.sh runs the recorded t8n corpus through the packaged xOneRS binary and refuses a tarball whose output differs from the pinned geth-XDC.
How to trace an XDC transaction with xOne tracers
Trace an XDC transaction with xOne: callTracer, prestateTracer, flatCallTracer and the struct logger. Example requests, response shapes, limits, parity counts.
How to upgrade or roll back an xOne node safely
Upgrade or roll back an xOneRS node on XDC: check the binary, upgrade followers first, back up the datadir, and never lower or restore the signer safety record.
XDC validator daily checklist: what to watch with xOne
A daily checklist for an XDC validator running xOne: Grafana panels, alert rules, producer log lines, seat watch, ethstats, disk lines and the version stamp.
How to verify an xOne release artifact on XDC
Check an xOne release download: SHA256SUMS, the version stamp against the tag, what ci/qualify-artifact.sh tests, and what the release page lacks today.
