A single ASIC holds only a small fraction of the entire Handshake network hashrate. Without a pool, finding a block would be pure luck. A mining pool bundles the computing power of many devices, finds blocks regularly as a result, and distributes the emission proportionally to the hashrate contributed - predictable instead of random. In return, the pool charges a fee, usually in the low single-digit percentage range.
The common models PPS, PPLNS and FPPS differ in how the risk of individual block finds is distributed between the pool and its participants - a detailed explanation is available on the mining pools overview page. For devices running continuously, the models largely converge over time; what matters is always considering fee and payout model together.
Compared to larger proof-of-work networks, Handshake is a relatively small network with only a few large pools - the selection is correspondingly manageable. Precisely because Handshake's naming system serves a special infrastructure function, the distribution deserves a close look despite the small selection: a single, highly dominant pool weakens the decentralisation of the underlying DNS root system.
Besides fee and payout model, other factors matter when choosing a pool: the proximity of the stratum server to your own location (shorter latency reduces the number of rejected shares), the minimum payout, and the transparency of the published statistics. Switching pools is possible at any time and takes only a few minutes: simply change the stratum address in the miner dashboard. Anyone hosting their Handshake devices with Cryptohall24 chooses the pool freely; our team is happy to help with setup on request.
