Whirlpool Coordinator Hosting for Fixed-Denomination CoinJoin
Whirlpool's fixed-denomination CoinJoin model (5 participants per round, 4 pool sizes) has a specific operational profile distinct from Wasabi-style rounds. Operators of Whirlpool-derived or compatible coordinators need hosting that handles 24/7 round operation across multiple pools simultaneously.

Whirlpool model context
The original Samourai Whirlpool implementation operated until 2024. Successor and compatible implementations continue. Whirlpool's fixed-denomination structure has specific advantages (smaller anonymity set per round but stronger forward privacy) and operational profile (multiple parallel pools, 5-participant rounds, automatic queueing).
Hardware
EPYC 7402P with 64 GB and dual NVMe at $189/mo handles a Whirlpool-style coordinator. Bitcoin node integration on a paired second node at $349/mo total.
Operational considerations
Whirlpool coordinators run multiple parallel pools (typical: 0.001, 0.01, 0.05, 0.5 BTC pools). Each pool maintains its own participant queue. Coordinator load is moderate but constant. Uptime is critical because rounds form on a continuous basis.
Pricing
$189/mo single, $349/mo paired. Related: bulletproof hosting, CoinJoin Romania, mixer hosting.
