Summary

Add services/storage/sia-hostd.yml: the Sia Foundation's official host implementation. Sia is a decentralized storage marketplace operating since 2015; hostd is its official, actively maintained Go host (MIT, latest release v2.11.0 2026-09-21) with an official Docker image (ghcr.io/siafoundation/hostd) and an official Docker compose guide.

Why this entry:

  • storage currently lists only Storj; Sia is the other long-running permissionless storage network (no signup, DC/VPS hosts are common).
  • wallet seed is user-supplied and funds live in the node's own wallet (payout.model: external, address_source: app), consistent with the payout registry rules — no private keys in the YAML.
  • collector starts as manual: hostd exposes a local REST API (port 9980, BasicAuth) with /api/wallet and /api/settings, which a future SiaCollector can read the same way the Storj collector reads the local storagenode API. Left to a follow-up app-side PR, per the collectors-are-code rule.

Deployment shape mirrors the Storj entry: critical volumes for consensus/host DB (/data) and renter data (/storage), RHP4/consensus ports published (9981 TCP, 9984 TCP+UDP per Sia's official compose guide), dashboard on 9980 with its loopback-bind caveat documented (Sia's own guide binds 9980 to 127.0.0.1; the port format here cannot express that, so the guide tells the operator to restrict it at the firewall), cpu_shares 4096 because the network dials the node back. health_signals is intentionally minimal pending a live log capture — only the generic "failed to" line is asserted, with its caveat documented in the entry.

Verified live on a Debian VPS: image pulls on linux/amd64, hostd version reports v2.11.0, the node starts with env-only config, syncs mainnet, and serves /api/state, /api/wallet and /api/settings.

Guide page added (docs/guides/sia-hostd.md); README lists, docs nav and the guides index are regenerated by the existing scripts; the hand-maintained counts move from 39 active/50 catalogued to 40 active/52 catalogued.

Type of Change

  • New service (YAML + guide)
  • New earnings collector
  • Bug fix
  • Feature
  • Documentation
  • Other

Checklist

  • ruff check app/ passes
  • ruff format --check app/ passes
  • Service YAML follows services/_schema.yml
  • Guide page added in docs/guides/ (if new service)
  • README service table updated (if new service)
  • No credentials or secrets committed

Additional verification: catalog-related test suite passes on the full set (tests/test_catalog.py, test_catalog_is_the_source_of_truth.py, test_catalog_loader.py, test_readme_generation.py, test_catalog_devices.py, test_confusable_services.py — 504 passed, 0 failed).

Summary by CodeRabbit

  • New Features
    • Added Sia (hostd) as an active storage service, with support for Linux AMD64 and ARM64. Setup requires a wallet seed, dashboard password, and storage location; users manage payouts manually.
  • Documentation
    • Added a guide covering setup, storage and network requirements, configuration, estimated earnings, collateral, and operational considerations.
    • Updated service listings and catalog counts to include Sia (hostd).

Change: Feature


Merge Risk: 🟡 Moderate · up to 80492

The new Sia hostd service exposes its password-protected admin dashboard on all network interfaces of the host, so a machine with a public address can reach it from the internet unless a firewall blocks the port. Restricting the binding to loopback requires deployment support that does not exist yet. One documentation count is also inconsistent.

change the Sia service mapping and guide to bind port 9980 to localhost.

- **18 services run as a browser extension or a desktop app** (Grass, Nodepay, Dawn, Helium, and more). CashPilot lists them with signup links and reads their balances where a collector exists.
- **6 GPU compute services** (Salad, Vast.ai, io.net, Nosana, Golem, Flux) need an NVIDIA card and run on their own software; CashPilot tracks them the same way.
- 39 active services in total, 50 catalogued; the 11 that died or broke are kept on [Discontinued services](discontinued-services.md) so nobody re-adds them.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the inactive-service count.

With 52 catalogued services and 40 active services, 12 are not active, not 11. Correct the count or narrow the sentence to the statuses it intends to include.

Comment thread services/storage/sia-hostd.yml Outdated
- Bind the dashboard to 127.0.0.1 (its API can spend the wallet), now that
  the catalog supports a host address on a port (GeiserX#423).
- 9981 is Sia consensus, not RHP4.
- Drop the "failed to" health signal: a fresh, healthy node logs
  "failed to get certificate for RHP4 net address" while it syncs.
- mem_limit 4g: hostd 2.11.0 reached 1.9 GiB within four minutes of sync.
- State that the wallet needs Siacoin before the node can earn, use Sia's
  recommended prices for the estimate, drop the unsourced /24 claim.
- Record that there is no referral programme for hosts.

Owner

Thanks, this was a good entry. I merged it with a few corrections, which went out in v1.41.0:

  • The dashboard now binds to 127.0.0.1. I added support for a host address on a catalog port in fix(deploy): let a catalog port bind to loopback, so a wallet dashboard stays off the internet #423, so the port format limit you documented is gone.
  • 9981 is Sia consensus, not RHP4.
  • I dropped the "failed to" health signal. A fresh, healthy hostd 2.11.0 logs "failed to get certificate for RHP4 net address" while it syncs, so the signal would have marked every new node as failing.
  • The memory limit is now 4g. hostd reached 1.9 GiB within four minutes of the initial sync.
  • The entry now says the wallet needs Siacoin before the node can earn, and the estimate uses Sia's recommended prices.
