[ANN] BumbleBeam — open-source Beam (BEAM) pool | PPLNS + SOLO | 0.5% fee

BumbleBeam
Open-source mining pool for Beam (BeamHash III)
pool.bumblebeam.org | source code (Apache-2.0)

Why another pool
Today, a single pool holds about two-thirds of Beam's hashrate. That is bad for the chain, and the only open pool code is from 2020–2021. BumbleBeam is a new pool with fully public code, so anyone can read how shares are checked and how payouts are calculated. Anyone can also run their own copy.

Pool details

Fee: 0.5% on PPLNS and on solo
Payout schemes: PPLNS (window = 2× network difficulty) and SOLO
Finder bonus (PPLNS): the rig that finds a block gets an extra 1% of it (after the pool fee) on top of its PPLNS share. In solo, the finder already gets the whole block. k
Minimum payout: 1 BEAM, paid every 2 hours. The network fee comes out of the payout (about 0.00001 BEAM to a regular address, about 0.01 BEAM to an offline/max-privacy address)
Payouts start after 240 confirmations, once the block's coinbase is in the pool wallet
Privacy: the public API never links an address to a hashrate or a balance. You open your stats by entering your own address
Share checks: every share is checked by our BeamHash III verifier. It is tested against the Beam core on 42,000+ cases, including real mainnet blocks.

Connect

Code:

Host: stratum.bumblebeam.org
PPLNS:  3333 (plain)   3443 (TLS)
SOLO:   3334 (plain)   3444 (TLS)
User:   <your Beam address>.<worker name>

lolMiner

Code:

lolMiner --algo BEAM-III --pool stratum.bumblebeam.org:3443 --user <address>.<worker> --tls on

GMiner

Code:

miner --algo beamhashIII --server stratum.bumblebeam.org:3443 --user <address>.<worker> --ssl 1

MXBM (open-source GPU miner, tested on this pool: RTX 3090, 52 Sol/s, 0 rejects)

Code:

mxbm --algo BEAM-III --pool stratum.bumblebeam.org:3443 --user <address>.<worker> --tls 1

NiceHash (passes the NiceHash pool verificator, algorithm BeamV3)

Code:

Host: stratum.bumblebeam.org   Port: 3443 (NiceHash connects over TLS)
User: <your regular Beam address>.<worker name>   Password: x

NiceHash doesn't accept long offline addresses as usernames, so use a regular one, and keep your wallet online to receive payouts.
BumbleBeam CPU miner (ours, open source: a way to take part without a GPU, not an income — about 0.5–1 Sol/s on a modern desktop, needs ~7 GB of free memory). Linux, macOS (Apple Silicon) and Windows builds on the releases page

Code:

bumblebeam-miner mine --pool stratum.bumblebeam.org:3443 --user <address>.<worker>
bumblebeam-miner bench 60      # what this machine does: runs/s and Sol/s

For solo, use 3444 (TLS) or 3334. The website has a start-mining guide with a profit calculator.

Open source

pool/server — stratum, share checks, PPLNS and solo accounting, payouts, HTTP API (Rust)
oracle — BeamHash III and difficulty checks. Tested against the Beam core and real mainnet headers, ~80× faster than the reference
miner — a readable CPU reference miner, every solution verified before it is sent (downloads)
Deployment guide (systemd or Docker), so anyone can run their own pool
