# Monero Plans FCMP++ Upgrade to Replace Ring Signatures By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/34955 Published: 2026-10-19T18:32:07.000Z Updated: 2026-10-19T18:32:07.000Z Section: Technology > XMR rose 8.33% in an Oct. 18 trading snapshot. Earlier privacy-coin market growth was driven chiefly by Zcash. Monero (XMR) plans to replace its existing ring signatures through the FCMP++ privacy upgrade, a network change separate from the token’s recent price rise and earlier privacy-coin market growth. Ring signatures conceal a transaction’s sender. Monero also uses stealth addresses to conceal recipients and Ring Confidential Transactions to hide amounts. FCMP++ stands for Full-Chain Membership Proofs plus spend authorization and linkability. It is a planned replacement for ring signatures, not a completed upgrade. In an [Oct. 18 trading snapshot]() taken at 1:03 p.m. ET (17:03 UTC), XMR stood at $592.13, up 8.33% over the preceding 24 hours. Futures volume reached $271.25 million during that period, compared with $16.25 million in spot volume. The gap shows more activity in futures than in spot trading during that window, but does not establish whether spot demand was strengthening. The [privacy-coin market figures published Sept. 24, 2026]() cover a different period. They show a five-month gain of $24.54 billion, bringing the sector’s value to $36.51 billion from $11.97 billion. Zcash (ZEC) contributed $20.27 billion of the increase, while Monero contributed $4.33 billion. Those sector figures precede the Oct. 18 XMR snapshot and do not show that the assets gained at the same time. Neither the trading snapshot nor the planned upgrade establishes a price path for XMR through 2030. ## Links in this article - [Oct. 18 trading snapshot](https://www.tokenpost.com/news/investing/34435) - [privacy-coin market figures published Sept. 24, 2026](https://www.tokenpost.com/news/investing/23796)
