# BrowserCoin Develops New Algorithm for Browser-Based Mining Sandglass algorithm announced to bring back browser mining against GPU farms. - **Source:** [Cryptocurrency News & Discussion](https://brifing.si/source/232d5583-2409-4c18-9de5-8344c1b6f934) - **Published:** 2026-07-19 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/022d169d-7ec2-4931-99a7-167869be79e1 ## Vision for Browser-Based Mining BrowserCoin envisions a system where users can become full nodes and mine simply by opening a browser tab, with no installation required. This aims to make participation in decentralized networks extremely easy. ## Rise of GPU Farms The project's initial PoW algorithm, Argon2id, was easily overtaken by GPU farms. Due to GPUs' bandwidth advantage, browser-based miners became non-competitive, endangering the network's decentralization vision. ## Sandglass: Revolutionary New Algorithm Developers designed Sandglass, a new PoW algorithm based on memory latency. This neutralizes GPUs' parallelism advantage, making browser-based mining competitive again. ## Technical Advantages of the Algorithm Sandglass works by performing dependent random read/write operations on a small memory buffer. Since each step depends on the previous one, GPUs cannot utilize their parallel processing power effectively. ## Comprehensive Test Results Tests on 90+ devices showed browser-based WASM implementation performing within 10% of hand-optimized native C code. Even the most powerful GPUs only achieved 1.6-3x advantage. ## Future of Decentralization This update strengthens BrowserCoin's core vision. Now anyone can participate in the network on equal terms through a browser tab, making truly decentralized mining possible. ## Sources covering this story - https://www.reddit.com/r/CryptoCurrency/comments/1v123ah/browsercoin_dev_update_we_redesigned_our/ — --- _Summary written by Brifing from the original reporting.
