Stellar introduces State Archival, a protocol solution to blockchain state bloat that archives unused ledger entries while maintaining security through Merkle proofs stored in History Archives. This approach enables Stellar to maintain low validator costs, high throughput, and scalability without requiring expensive hardware.
Tansu has received an SCF28 Activation award to build infrastructure that anchors Git commit hashes on Soroban. The system creates a decentralized record of code changes, helping maintainers verify project integrity and combat centralized platform risks without disrupting existing workflows.
A comprehensive tutorial on migrating smart contracts from Ethereum's Solidity to Soroban's Rust SDK, comparing the two platforms and demonstrating how to build a Hello World contract in both languages.
BlockEden.xyz unveiled their Soroban Indexer and GraphQL at Stellar's Meridian conference in Madrid from September 26–28, 2023. The article shares their pitch deck with 13 slides showcasing the innovations. Contact details and source link are provided.
Goldsky announces the general availability of Mirror, its realtime crypto data streaming platform that syncs onchain data directly to user databases. It supports 40+ networks including Stellar, reducing costs and ETL complexity. The platform offers blazing-fast performance, dual interfaces, and is now accessible to everyone without a credit card.
Stellar's Protocol 21 upgrade activated on June 18, 2024, introducing five Core Advancement Proposals (CAPs) that enable passkey support for smart contracts, improve state archival, and reduce transaction costs through VM optimization and module caching.
A step-by-step tutorial for setting up three Stellar Core validation nodes on Ubuntu 22.04, covering domain configuration, PostgreSQL setup, and Stellar Core installation with example configuration files.
Stellar and Soroban documentation sites have merged into a unified developer experience. The Stellar Development Foundation is launching the Deep Dive Docs Bounty program from May 29 to August 7, 2024, offering XLM rewards for community contributions to improve developer documentation.
The development team released updates including a custom risk framework creation UI with drag-and-drop support, Lido liquid staking analytics, and Stellar chain analytics data pipelines and dashboards. 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.
