BC3 mining pool · SHA3-256t

Mine BC3 on your own hardware.
Keep the entire block reward.

bc3.online pays out inside the block you find — the subsidy goes to your address in the coinbase transaction itself and never passes through the pool's wallet. Our only revenue is the block's transaction fees.

Steady payouts for steady work

PPLNS (Pay Per Last N Shares) splits each found block's subsidy between everyone who contributed shares in the recent window, proportional to work. The right choice when your hashrate is small relative to the network.

Paid inside the coinbase

When a block is found, the distribution is written directly into the coinbase transaction — one output per participant. No balances held by us, nothing to withdraw. Spendable after 100 blocks maturity.

The window

Your shares are difficulty-weighted over a rolling window of 2× the network difficulty. Payouts below 0.0001 BC3 are folded into the window's largest participant instead of creating dust.

Username is your BC3 address, optionally with a rig name: yourBC3address.rigname — password is ignored. Already running your own miner? Point it at the endpoints above.

The fee model: 0% of your reward

You get the subsidy

The full block subsidy is paid to your address (or the PPLNS window) as the first outputs of the coinbase transaction. Trustless — we cannot withhold it even if we wanted to.

We get the transaction fees

The pool's revenue is the fees from the block's transactions — close to zero on the young BC3 network today. We are betting on the network growing.

100 blocks maturity

As in Bitcoin, coinbase rewards become spendable after 100 blocks (~17 hours). That is a consensus rule that applies to every pool — nobody can pay out faster.

Get started in five minutes

  1. Get a BC3 address. Create a wallet in BitcoinIII Core — or right here in your browser (coming soon; keys never leave your browser).
  2. Download the miner from releases and unzip. Verify the SHA256 checksum against the release notes.
  3. Start it and pick a mode. Paste your address, name your rig, choose PPLNS (steady payouts) or solo (the whole block or nothing).
  4. Mine. The client shows your hashrate, shares, and — in solo mode — estimated time to block.
Important about addresses: BC3 uses exactly the same address format as Bitcoin (bc1…). Never send BTC to a BC3 address or vice versa — the transactions live on different chains and cannot be moved between them.

A block is found when a share's difficulty reaches the network difficulty. On average it takes difficulty × 2³² hashes; variance decides the rest.
