Frequently Asked Questions
What is FCMP++ in Monero?
Full-Chain Membership Proofs (FCMP++) is a major Monero protocol upgrade that replaces ring signatures with cryptographic proofs covering every unspent output in Monero’s entire blockchain history. This eliminates the statistical analysis attacks possible against smaller ring signature decoy sets, significantly strengthening Monero’s transaction privacy.
What is the CARROT upgrade in Monero?
CARROT is a companion upgrade to FCMP++ that improves Monero’s stealth address derivation and scanning process, making wallet operations more efficient and improving compatibility with future protocol improvements.
When will Monero FCMP++ go live on mainnet?
As of May 2026, FCMP++ and CARROT launched on beta stressnet on May 6. A Trail of Bits security audit of the full codebase integration runs May 11–22, 2026. A mainnet activation date has not been announced but developers are targeting Q3 2026 if the audit clears.
