Browser mining is when a website uses a visitor's CPU, via Web Workers and WebAssembly, to compute proof-of-work hashes for a mining pool — and the publisher earns cryptocurrency. This guide covers what it is, whether it still works in 2026, how much it pays, and how to deploy it in five minutes.
Browser mining is similar to classic crypto mining — devices compete to solve proof-of-work puzzles — except the work happens inside a web page. A script loads a WebAssembly hashing kernel, spawns Web Workers, receives jobs from a pool over the Stratum protocol, and submits valid shares. Valid shares are credited to workers connected to the pool, and payouts go to the publisher's wallet. See the full technical pipeline here.
Yes, when expectations are level. A desktop session on MinotaurX produces roughly 250–400 H/s per core, a laptop ~300 H/s, a mobile browser noticeably less — which is why desktop audiences earn about 5× more than mobile. Modeled against current difficulty and DOGE prices, publishers earn roughly $1–$4 / month per 100 visitor-hours.
