xOne on Apothem vs net2040: what changes for an operator
Compare xOne on XDC Apothem and net2040: chain id, V2 switch block, bootnodes, state size, sync modes, --mine rules, quiet window and measured follower numbers.
Choosing an xOne sync mode on XDC: a decision table
Pick full, snap, minimal or archive for an xOne node on XDC. One table maps your need to a mode, with measured datadir sizes and the flags of all four clients.
How to plan disk space for an XDC node with xOne
Plan disk for an XDC node with xOne: the node's 2%, 3% and 1% free-space lines, the 15% alert, datadir sizes per sync mode, segment files and MDBX limits.
Disk watermarks and block sealing: why a full disk stops xOne
Why a low disk stops block sealing in xOne on XDC: one gate for import and producer, the NoSpace second line, and what the four clients do at the exit line.
Four XDC clients on one host: load and disk records
What xOne recorded with four XDC clients on one shared host: the 27-minute Python seat outage, load averages, disk lines and the memory cap, with sources.
What a refused block leaves behind: xOne's invalid-block evidence
When xOneRS refuses an XDC block, it keeps the block and the error in a bounded evidence directory: what an entry holds, the 16-entry and 1 GiB bounds, limits.
How to join net2040 with xOne: step-by-step guide
Join net2040, XDC chain 2040, with xOne: get the binary, pass a peer, start the node, check the head against a reference, resume, swap the binary, pick a mode.
Measuring an xOne node before and after a change with measure-node.sh
How ops/bench/measure-node.sh records RPC latency, block import times, disk I/O and memory of a running xOne node before and after a window, and only reads.
One tracker for four XDC clients: how the hourly net2040 report works
How the hourly net2040 tracker on xOneRS issue 140 is built: one row per node, head and lag against the archive tip, the stats-board flag, and the mint column.
How to run an XDC validator on net2040 with xOne
How to run an XDC validator on net2040 with xOne: follow the network, import a signer key, pass the mint gate, start the producer, and hand off the seat safely.
Banning a peer by hand on xOne: admin_banPeer on XDC
How an xOneRS operator bans and unbans a peer by node id with admin_banPeer, how the ban differs from automatic reputation bans, and what it does not keep.
How to check an xOne node's networking from another host
The xOneRS p2p live checks: advertised address and NAT, enode and peer probes, a discovery bootnode, the node allowlist and interop with other XDC clients.
How xOne chooses and drops XDC peers: dial sample, score, bans
How an xOneRS node picks peers to dial from a seeded discovery sample, scores each peer's offences, bans a peer at 100 points, and where operator bans fit.
Running xOne with Prometheus and Grafana in Docker Compose
How to start the xOneRS monitoring stack with Docker Compose: Prometheus, Grafana, node_exporter and an optional Alertmanager on loopback, and how to check it.
xOne release checklist: upgrade the four clients on XDC
Checklist for xOneRS, xOneTS, xOnePy and xOneC: find the release, check the file, upgrade followers first, prove the start, roll back, and see the open defects.
Exposing xOne JSON-RPC safely on XDC: limits, namespaces, JWT
The xOneRS JSON-RPC limits an operator relies on: 100-item batches, 5 MiB bodies, -32005 rate limits, namespace lists and -32601, JWT, and subscriptions.
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.
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 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.
How xOne refuses the wrong XDC network for a datadir
How xOneRS keeps a datadir on its own chain: the chain marker with chain id, genesis hash and consensus schedule, the --chainspec.update rule, and peer checks.
Running an XDC RPC endpoint on xOne: a checklist for providers
A checklist for public XDC JSON-RPC on xOneRS: history and archive, limits, TLS and per-key method lists, health checks, log queries and what to monitor.
The xOne CLI for XDC operators: attach, rpc check, wait-ready and more
What the xOneRS command line gives an operator next to a running node: xone attach, rpc check, wait-ready, sync-status, evm t8n and statetest, with exit codes.
The xone db toolkit: inspect, check, repair and compare an XDC node's database
Every xone db subcommand in xOneRS, grouped by job: what each reads or writes, which ones are safe beside a running node, and which need the node stopped.
XDC node hardware and disk requirements for xOne
XDC node hardware requirements for xOne: no CPU or RAM sizing is published. Read the enforced limits, disk watermarks, and the memory and disk use measured.
History retention in xOne: pruning bodies, receipts, logs and state, and backfill
The xOneRS --history flags: how long a node keeps bodies, receipts, logs, state and preimages, how to prune a stopped datadir, and backfill after snap sync.
Serving HTTP and WebSocket JSON-RPC on one port with xOne
How xOneRS serves HTTP and WebSocket RPC on one port: when it shares the listener, what stays separate per protocol, the TLS rule, and one admin_stopWS caveat.
