Browser-based crypto mining is making a quiet return in 2025, offering a low-barrier way to earn crypto, but its profitability and impact remain limited. Browser-based crypto mining sounds like a dream: Just open a webpage, let it run, and your computer starts earning crypto in the background. No bulky ASICs, no GPU farms, no long setup tutorials — just your browser doing the heavy lifting. The idea blew up in the late 2010s with tools like Coinhive, which let website owners mine Monero (XMR) using JavaScript. At first, it seemed like a clever alternative to ads; visitors donated a bit of unused CPU power, and websites earned crypto. But then came cryptojacking. Sites began running these scripts without user permission, draining resources and slowing down devices. In 2019, Coinhive shut down, citing shrinking returns and mounting scrutiny. Read more
Rootstock’s merged mining hit an all-time high in Q1 2025, even as DeFi TVL dropped 20% and user activity cooled across the Bitcoin DeFi ecosystem. Smart contract platform Rootstock, the home of decentralized finance (DeFi) on Bitcoin, saw a sharp increase in network security and mining engagement in the first quarter of 2025, even as activity cooled. Merged mining participation surged to an all-time high of 81%, up from 56.4% in Q4 2024, driven by the integration of major mining pools Foundry and SpiderPool, according to Messari’s first “State of Rootstock” report for 2025, shared with Cointelegraph. The heightened miner interest boosted Rootstock’s hash power to over 740 exahashes per second, surpassing the total Bitcoin network hashrate recorded in October 2024. As a result, the network is now considered to be in a “mature phase” of merged mining growth. Read more
