Announcement Official Record is live on-chain — Scrypt mining planned next

Published

HobbyHash Coin now publishes an Official Record — an append-only public ledger of project statements sealed with SHA-256 and anchored on the HOBC chain with one OP_RETURN transaction per seal (prefix HOBCOR1 + content hash).

Tri-PoW (SHA256d + KawPow + RandomX) remains live. Scrypt is planned work and is not active yet.

Mining Guide

Set up HOBC solo mining for ASICs, nano SHA-256 devices, KawPow GPUs, and RandomX CPUs in the always-on Tri-PoW race.

Algorithm and mining style

HobbyHash Coin uses Tri-PoW after height 16800: SHA-256d for ASICs, KawPow (RVN-compatible) for GPUs, and RandomX for CPUs. All three race for every block — always on, flat 45 HOBC reward. Alternating-algo windows and height-based window schedules are retired.

Solo mining means a miner is trying to find a real block. Accepted shares prove your miner is working, but they are not the same thing as finding a block.

Nano miners and small SHA256 devices

Small miners can use the Nano Pool when they need very low share difficulty to show activity. This is useful for nano miner setups, Bitaxe-style devices, NerdMiner-style hobby miners, USB test miners, and other low-hashrate SHA256 hardware.

Use the Nano Pool at <code>stratum+tcp://pool.hobbyhashcoin.com:5556</code> with a worker name like <code>HOBC_ADDRESS.nano1</code>. The pool is still solo only, so accepted shares show valid work but do not guarantee a payout.

GPU and CPU pools (always-on race)

GPU miners use port <code>5558</code> with KawPow software (lolMiner, T-Rex, GMiner, etc.) — always on after height 16800. The GPU pool is solo-only like the SHA and CPU pools.

CPU miners use port <code>5559</code> with RandomX software (hobc-rxminer). SHA, GPU, and CPU pools stay on continuously — there are no idle windows. Live race hashrate: <a href="/network/">/network/</a>.

After height 16800 every algo pays a flat 45 HOBC block reward. Former V4 hashrate tiers are retired.

Main Pool vs Nano Pool vs PPLNS Pool

  • Main Pool: intended for normal SHA256 ASIC miners and higher-hashrate devices. Current site text lists start difficulty as 5000.
  • Nano Pool: intended for very small miners, test miners, and low-hashrate SHA256 devices. Current site text lists start difficulty as 0.005.
  • PPLNS Pool: shared proportional pool on port 5557. Rewards split by recent work window when the pool finds a block. Current site text lists start difficulty as 5000.
  • GPU Pool: KawPow solo pool on port 5558. Always on in the Tri-PoW race. Use lolMiner, T-Rex, or GMiner with the same worker format as SHA pools.
  • CPU Pool: RandomX solo pool on port 5559. Always on in the Tri-PoW race. Use hobc-rxminer with the same worker format as SHA pools.
  • Low difficulty helps tiny miners submit shares more often so the dashboard can show activity.
  • Higher difficulty reduces share spam for stronger miners.

Shares and difficulty

  • Accepted share: the pool accepted submitted work from your miner.
  • Rejected share: the pool rejected submitted work. Causes include stale work, wrong settings, bad address format, latency, or miner firmware issues.
  • Stale share: work submitted too late, usually after the pool has moved to newer work.
  • Best difficulty: the highest-difficulty share seen from a miner or pool over a period.
  • Network difficulty: the chain target a share must meet or beat to become a real block.

Blocks and payouts

A big share only wins a block if it meets or beats the current network difficulty target. Shares below network difficulty are useful progress signals, but they are not blocks.

Current site copy says pool payouts go to the HOBC address before the dot in the worker name. Use YOUR_HOBC_ADDRESS.worker1 or YOUR_HOBC_ADDRESS.nano1 — always include a dot and a worker suffix, not the address alone.

When your miner finds a solo block, the HOBC reward pays automatically to the address before the dot after the coinbase reaches 100 on-chain confirmations. Until then the block may show as waiting for maturity. That wait is normal coinbase maturity, not a manual pool hold.

The Workers count on pool status includes every miner with recent accepted shares in the active session window, not only live stratum socket connections.

Mining is not guaranteed income. Payouts depend on finding a real block under current pool rules.
