Is Monero Traceable? What the FCMP++ Upgrade Changes, and When

As of Oct 23, Monero developers are preparing FCMP++, a privacy upgrade that would replace ring signatures with full-chain membership proofs, letting a transaction prove it spends one of more than 150 million spendable outputs instead of one of 16 ring members. It is not live: getmonero.org had announced no fork-enabled release, and a developer's non-binding draft plan listed Oct 14-21, 2026, for a first fork-enabled release and activation around the first week of March 2027. Monero currently hides sender, receiver and amount by default, using ring signatures, stealth addresses and Ring Confidential Transactions; existing addresses would keep working after FCMP++, though wallets would need an update and one-time re-scan.
