Full-Chain Membership Proofs (FCMPs) will replace rings in the Monero protocol to significantly improve sender privacy. FCMPs will prove the output spent is one of any output on the chain, effectively removing risks associated with rings. This will increase the anonymity set from 16 to 100,000,000. nostr:nevent1qqsfw3tya8fnpv3wxndxcf5wmc0r0mfsjt3c795f9dtf0c6fywdtflcppemhxue69uhkummn9ekx7mp0qgs0eac2gh86s9l24qfmnw52xawhz0f3d862yleaetpafygjmanaxlsrqsqqqqqpwmpr6f
