Internal mining

Internal mining keeps transaction selection, proof construction, nonce search and block submission in one Core process.

Prepare

Run the production hardware check:

parano1d --check-hardware

Obtain a payout address from the node wallet:

parano1d
parano1d-cli address --list
parano1d-cli stop

The active wallet address is used automatically when no explicit payout is configured.

Start

In the foreground:

parano1d --mode miner --cpu-threads 12

Or update a systemd unit:

ExecStart=/usr/local/bin/parano1d \
  --config /etc/parano1d/parano1d.toml \
  --mode miner \
  --cpu-threads 12

Then reload and restart:

sudo systemctl daemon-reload
sudo systemctl restart parano1d

Readiness

Ordinary mining requires one authenticated peer and a synchronized chain. Check:

parano1d-cli status
parano1d-cli peers
parano1d-cli mining

The process prepares its embedded B25 and B255 proof matrices and selects the best available CPU backend. Each mining session starts with B25. Its first completed preparation permits B255 if prepare_time_B25 × 4 ≤ 20 seconds. Eligible page count then determines whether a template needs the larger class. See Mining architecture.

CPU planning

--cpu-threads is the total shared budget for proof and PoW phases. Do not set it higher than the logical CPUs available to the service's cgroup or virtual machine.

Leave capacity for the operating system and public P2P service on an infrastructure node. A dedicated miner can use every visible logical CPU.

Wallet transaction proving has local priority over ongoing mining work. This does not change the transactions or blocks accepted by other nodes.

Payout changes

The active wallet address is resolved for each new template. Changing it invalidates or refreshes local work at a safe boundary. An already immutable template cannot have its payout rewritten.

To pin a separate payout for the process:

parano1d --mode miner --miner-address o1...

Use the complete bech32m address.

Stop

Stop through RPC or the service manager:

parano1d-cli stop

sudo systemctl stop parano1d

Graceful shutdown cancels mining, closes networking and flushes MDBX. Do not send repeated hard-kill signals merely because an active proof takes several seconds to reach its cancellation boundary.
