Cardano founder Charles Hoskinson has publicly applauded the Monero community for the launch of the FCMP++ beta stressnet, calling it a “massive deal” and a “huge upgrade” for the privacy coin. The development represents a fundamental shift in Monero’s technology, ending a multi-year research and engineering effort.
Full-Chain Membership Proofs (FCMP++) are designed to replace the traditional ring signature model. Instead of proving ownership over one of 16 output groups, the new system allows a spender to prove they control one out of more than 150 million outputs spanning the entire Monero blockchain. The upgrade was activated on the stressnet at block 2,997,100 on May 6, marking the beginning of public testing for both FCMP++ and the companion CARROT addressing protocol.
CARROT introduces security, privacy, and usability improvements while remaining backward-compatible with current addresses. The joint development has been ongoing for over two years, with parallel security audits and formal reviews. Hoskinson emphasized his pride in the Monero team’s “relentless building” that made the milestone possible.
Coinciding with this news, the Cardano ecosystem is preparing for its own network evolution. The van Rossem hard fork has been submitted to the Preview testnet, and according to Intersect, the governance action for ratification is set to occur at the epoch boundary around May 8 at 00:00 UTC. Node version 11.0.1 and DB-Sync 13.7.0.5 pre-releases have also been made available in support of the upgrade.
