Protocol 23 introduces eight Core Advancement Proposals (CAPs) to the Stellar network, featuring major performance improvements for Soroban including reduced costs, parallel transaction execution, and automatic state restoration. The mainnet vote is scheduled for September 3, 2025.
Protocol 23 brings significant upgrades to the Stellar network through eight CAPs focused on Soroban performance and functionality. Key improvements include live state prioritization (CAP-0062) separating archived and live state into distinct databases, parallel transaction execution (CAP-0063) enabling multi-core processing, a reusable Wasm module cache (CAP-0065) reducing parsing and validation overhead, and in-memory Soroban state (CAP-0066) eliminating disk reads and enabling automatic entry restoration. Additional enhancements include unified asset events (CAP-0067) emitting events in SAC format, new host functions for contract introspection (CAP-0068) and string/byte conversions (CAP-0069), and configurable SCP timing parameters (CAP-0070) for dynamic ledger optimization. The protocol went live on Testnet July 17, 2025, with mainnet voting on September 3, 2025.
