Additional progress includes AVS architecture setup, blockification processor upgrade, storage proof POC, protocol native token tracking, and RTM creation UX redesign.

Protocol 21 introduces BucketListDB, a new database backend for Stellar validators that replaces SQL and in-memory modes. This upgrade provides faster reads/writes, reduced memory and disk usage, and supports parallel IO for future protocol enhancements.

The development team shares updates from April 26, 2024, including bug fixes, new UI testing for the Custom Risk Framework, and live Governance and Tokenomics V2 dashboards. Key advancements feature Stellar Soroban nodes deployment, internal client readiness, and API support for circuit generators. Additional improvements cover data pipelines, price oracles for Optimism tokens, and Ethereum/NEAR analytics.

The Stellar Development Foundation announced it will limit historical data access on its free Horizon service to one year of rolling data, effective August 1st, 2024. This change aims to reduce operational overhead and eliminate a centralized point of failure in the network, while directing users with longer historical data needs to alternative solutions like Hubble, third-party Horizon providers, or self-hosted infrastructure.

The Stellar Development Foundation launched the Soroban Security Audit Bank, distributing up to $1M in audit credits from six top-tier firms to 20-30 high-priority projects building on Soroban to strengthen smart contract security across the ecosystem.

The Stellar Development Foundation ran a dogfooding experiment called the Okashi Cakewalk, a web-based smart contract game built on Soroban that enabled all SDF employees—regardless of technical background—to write, deploy, and invoke smart contracts. Over 170 NFTs were minted on Futurenet, demonstrating successful onboarding to Soroban development and providing valuable UX feedback to the Okashi team.
