Announcement Android wallet 0.2.23 can mine from your phone - Windows app updates

Published

HobbyHash Wallet for Android 0.2.23 is out. We also released a faster windows app.

You can mine the HobbyHash CPU pool from the phone. Open Start mining, choose 10% to 80% of the phone CPU, and start. The page shows your hashrate, accepted shares, and blocks found for your wallet address.

Phones already on the release app will be offered this update. You can also download it here: https://hobbyhashcoin.com/downloads/#android-wallet
Pool operators

Pool config validator

Test your HOBC marker fields and generate a deployable config before you go live. Wrong lengths or spoofed identity can make blocks reject — or get your pool blocked.

Marker field limits (consensus)

These caps are enforced by HobbyHash Core when parsing the coinbase marker. Live HobbyHash pools keep the last N characters when a value is too long.

  • hobc_marker — JSON boolean only: true or false. Required for SHA ckpool. Numbers like 1 or 101 are ignored and the marker stays off (blocks reject with bad-hobc-marker).
  • pool_id — 1 byte integer (0–255). Required. Separate from hobc_marker.
  • algo — 1 byte. 0 = SHA-256d, 1 = KawPow, 2 = RandomX. Required.
  • winning_share_diff — float32. Required (pool fills this on solve).
  • pool_site — max 24 ASCII printable characters. Optional but strongly recommended.
  • worker_name — max 16 ASCII printable characters (suffix after the last dot). Optional but recommended.
  • rig_model — max 16 characters in consensus; current HobbyHash pool builders omit it to leave scriptSig headroom.
  • Full marker must fit in the coinbase scriptSig (≤ 100 bytes) with height/extranonce. Keep site ≤ 24 and worker ≤ 16.

Do

  • Use your real public domain or site label (example: pool.example.com).
  • Pick a stable pool_id for your site and keep it forever.
  • Set algo to match the pool you are running (SHA / KawPow / RandomX).
  • Keep pool_site ≤ 24 characters and worker labels ≤ 16 characters.
  • Use printable ASCII only (letters, digits, dots, dashes, underscores).
  • Validate here, then paste the generated config into your pool before miners connect.
  • Use a current HobbyHash pool build — census heartbeats auto-report to HobbyHash (no census URL or token setup).

Don't

  • Don't use pool.hobbyhashcoin.com unless you are HobbyHash Coin LLC.
  • Don't forge another operator's site name or pool identity.
  • Don't put miner IP addresses in the marker or coinbase tags.
  • Don't leave pool_site empty if you want explorer / network-race attribution.
  • Don't paste emoji, spaces-only labels, or non-ASCII hostnames into marker fields.
  • Don't assume a long worker name survives — only the last 16 characters of the worker suffix are kept.
  • Don't set hobc_marker to a number (1, 101, etc.). Use JSON true. Numbers silently disable the marker in ckpool.

hobc_marker must be a boolean

Correct — JSON boolean true "hobc_marker": true
Wrong — number 1 is ignored by ckpool "hobc_marker": 1
Wrong — pool id belongs in hobc_pool_id, not hobc_marker "hobc_marker": 101

Network census (automatic)

Current HobbyHash SHA, KawPow, and RandomX pool builds automatically POST a once-per-minute hashrate heartbeat to hobbyhashcoin.com. You do not need a census token or census URL for that. Mining RPC stays on your local node. Set hobc_census_hub=false or HOBC_CENSUS_HUB=0 only if you must disable hub reporting.

Good vs bad examples

Good site (24 chars or less) pool.example.com
Too long (will keep last 24 chars only) solo.super-long-hostname.mining.example.com
Good worker suffix rig1
Too long worker suffix (keeps last 16) garage-basement-rig-01
Full miner username stays ADDRESS.worker — only the part after the last dot is stamped hobc1qabc…ullu.rig1

Paste your ckpool.conf to check

Paste an existing SHA pool JSON config. This catches the common hobc_marker mistake (using 1 or a pool id instead of true).

Private RPC passwords stay in your browser — nothing is uploaded.

    Validate & build config

    Results update live as you type. Fix every error before you deploy.

    Max 24 printable ASCII characters. Example: pool.example.com

    pool_site0 / 24

    Integer 0–255. Official HobbyHash site uses 1–5 — third parties must use their own site string.

    What miners put after the address dot. Max 16 chars stamped. Example: rig1

    Sample worker suffix (optional test)0 / 16

    Off-chain census label. Not limited by the 24-char marker site field.

    Live check

      Generated config

      Copy only after the live check shows no blocking errors. Replace RPC credentials and addresses before running. Census heartbeats auto-report to HobbyHash — no census token or URL is required in the generated config.
