Monero releases new stressnet version ahead of October hard fork

Monero (XMR) launched version 3.0 of its stressnet on September 25, 2026, to test the integration of FCMP++ and Carrot protocols. The update includes support for hot-cold wallets, RandomX v2 compatibility, and transaction relay improvements. A scheduled hard fork is set for October 5 at block 3,102,800. This version is not backward compatible, requiring users to resync their databases. FCMP++ aims to replace ring signatures with a full-chain membership proof system to enhance privacy, while Carrot introduces new address management features.
