Qortium Network

A QDN topology viewer and data-collection pipeline for Qortium Previewnet. The viewer ships as qdn://APP/Network/Network; its current and historical data is published separately under DATABASE/Network/Network and SNAPSHOT/Network/Network.

Viewer

The React viewer currently provides:

• an interactive chain/QDN-data graph with pan, zoom, reset, and node focus;
• filters for I2P/IP chain and data connections;
• node, link, country, and Core-version summaries with detail modals;
• country flags and version rings, with details for the selected node;
• snapshot-history navigation with a slider, older/newer controls, and Left/Right Arrow keyboard shortcuts;
• bundled sample data when published QDN data cannot be loaded.

The app loads latest.json, index.json, and historical snapshot files from DATABASE/Network/Network through Qortium Home's qdnRequest bridge. In a plain browser it performs the same read-only requests against http://127.0.0.1:24891 by default. Set VITE_QORTIUM_NODE_API_URL to use a different development node.

The viewer supports Classic and Modern QDN UI styles, along with Home theme, accent, and text-size settings. It does not define a Fun style.

QAVS

The app is at QAVS 1.4.0: 1.4 is the minimum Qortium platform level and the patch number is the app release. vite.config.ts reads package.json, injects the visible version badge, and emits dist/qortium-app.json with the name Network and the current version during every build.

Develop and publish the viewer

npm install
npm run dev
npm test
npm run build
npm run preview

Publish a built viewer to the default Previewnet identity:

npm run qdn:publish

The publisher reads dist/, uses the local Core at http://127.0.0.1:24891, and defaults to ~/qortium/git/qortium-core/preview/secrets/initial-minting-accounts.json. Overrides use the QORTIUM_NETWORK_ prefix. The render URL is http://127.0.0.1:24891/render/APP/Network/Network.

Collect topology data

Generate a current snapshot, SVG, and the QDN payload directories with:

python3 tools/network-topology-data.py --no-png

The collector starts from the configured seed nodes, then breadth-first probes reachable peers through their public read-only APIs. It deduplicates by host and node ID, treats missing edges as unknown rather than disconnected, and supports --no-discover, --max-hops, --max-nodes, --api-port, --probe-timeout, and --probe-workers.

Collection uses /admin/info, /admin/status, /peers, and /peers/data; it does not inspect private node state. The defaults allow four discovery hops, at most 250 queried nodes, public API port 24891, a five-second probe timeout, and 12 concurrent probe workers. --max-extra-peers separately limits how many non-operator peers are drawn. A reachable node becomes an observer in its own right, so the resulting topology can include non-seed and multi-hop links rather than making every connection appear to terminate at a seed.

I2P-only peers cannot be probed over a clearnet API. When Core's recordPeerExchange setting is enabled, the collector also reads recent peer-exchange.jsonl records from each seed and adds approximate gossip-derived I2P edges. The seed configuration defaults that remote path to qortium/preview/peer-exchange.jsonl relative to the VPS account home; this is the deployed seed layout, not the local source checkout. Use --no-gossip, --gossip-window-hours, or --gossip-tail-lines to control this input.

Clearnet IPv4 nodes receive offline country lookups from the vendored tools/geoip-ipv4-country.bin.gz; no peer IP is sent to an external geolocation service. Rebuild the table with:

python3 tools/build_geoip_ipv4.py

Default outputs are:

• target/preview-topology/preview-topology.json
• target/preview-topology/preview-topology.svg
• target/qdn-topology-data/qdn-resources.json
• target/qdn-topology-data/DATABASE/Network/Network
• target/qdn-topology-data/SNAPSHOT/Network/Network

The DATABASE payload contains latest.json, index.json, individual files under snapshots/, and a compact topology record. The tool retains at most 1,000 historical DATABASE records. The SNAPSHOT payload is the point-in-time resource for the current run. qdn-resources.json records both resource directories for the publishing scripts.

Publish topology data

After generating payloads, publish both data resources or the viewer and data together:

npm run qdn:publish:data
npm run qdn:publish:all

qdn:publish:data publishes both DATABASE/Network/Network and SNAPSHOT/Network/Network. The shared publish helper uses the current local development default ~/qortium/git/qortium-core/preview/secrets/initial-minting-accounts.json.

Scheduled collection and publishing

npm run qdn:collect
npm run qdn:auto-publish -- --dry-run
npm run qdn:auto-publish

qdn:collect adds one snapshot to target/preview-topology and prunes archived files older than 14 days by default. qdn:auto-publish considers archived records after the last selected timestamp, rejects records with collection errors or seed-height disagreement, selects the strongest eligible record, and publishes the DATABASE resource only. Its default minimum gap is eight hours.

The production rootless systemd collector/publisher setup is documented in deploy/README.md. The timers publish data only; viewer code is still published manually with npm run qdn:publish.
