Tomer from SDF presented Soroban, Stellar's new smart contracts platform built on WebAssembly and Rust. The talk covered Soroban's architecture, security tooling including a new Audit Bank and Certora partnership, and live demos of DeFi applications like Blend lending protocol and Beans app enabling cash-to-yield access.

Soroban smart contracts launch keynote covering three pillars: technical design decisions, 100+ ecosystem projects building on Soroban with 40 presenting, and cash-to-DeFi integration unlocking real-world asset connections.

Stellar ecosystem builders showcased 15+ projects at Meridian conference, including Comet AMM, EZA developer platform, Wavy P2P exchange, SubQuery indexer, Phoenix DEX, and infrastructure tools. Focus on DeFi primitives, real-world assets, and developer onboarding on Soroban.

Stellar Development Foundation held its Q3 2023 quarterly review, highlighting Soroban's arrival on testnet with protocol 20, the successful Meridian 2023 conference in Madrid, Circle's EuroCoin launch on Stellar, and MoneyGram's plans for a non-custodial wallet. The network saw 7.6 million total accounts and 76 million payments in Q3.

Fred from Lightmean demonstrates how to build Web3 games on Stellar using Soroban smart contracts, covering gameplay validation, NFT rewards, in-game currency management, and Freighter wallet integration with a live pool physics game demo.

SDF Q2 2023 quarterly review covering Soroban smart contracts platform progress toward mainnet launch, MoneyGram access milestone reaching one year, Franklin Templeton's on-chain money fund surpassing $270M AUM, and ecosystem growth with 70+ projects building on Soroban.

Chad Ostrovsky from AhaLabs discusses smart contract developer tooling for Soroban, comparing Rust-based development approaches across Near, Soroban, and Cosmwasm. He explains Rain, an ABI system and interactive documentation tool, and explores the philosophy behind Soroban's no-std constraint and performance optimization.

Cubist co-founders Fraser Brown and Riyadh Wabi discuss their cross-chain dApp development toolkit, the state of zero-knowledge proofs, and why Soroban's testing infrastructure sets a new standard for blockchain developer experience.

Stellar Core developers discussed replacing the variable rent balance system with a fixed expiration ledger approach for state expiration. The new model simplifies user experience and downstream system integration by storing a single expiration ledger per entry instead of periodically deducting variable rent fees.

Soroban design discussion on state expiration and storage. Team proposes unified storage interface combining temporary and restorable entries with rent-based model, automatic rent bumps on access, and optional manual bumps. Short-term entries (15 min) charged at lower rate than long-term (30 days) to incentivize temporary storage use.

Stellar Development Foundation's Q1 2023 quarterly review covering network growth to 7.3M accounts, $419M relevant asset transaction volume, Sorobon smart contract platform progress with two preview releases, and ecosystem initiatives including the $100M Sorobon Adoption Fund supporting developer adoption.

Soroban Developer Workshop livestream featuring Paul from SDF and Morgan from useSoroban.app demonstrating how to write your first smart contract on Soroban, including Hello World examples and stateful contract development with storage operations.

SDF hosted the Stellar Community Fund 12 project pitch event featuring 10 Soroban and Stellar ecosystem projects presenting their proof of intent deliverables, including developer tools, DeFi protocols, infrastructure, and financial inclusion applications.

Stellar core developers discuss three approaches for storing scalable network configuration settings in dedicated ledger entries instead of the ledger header, with approach two using Soroban emerging as the preferred option for simplicity and flexibility.

Developer walkthrough of Fast, Cheap, and Out of Control, a Soroban smart contract coding game that teaches optimization through competitive challenges. The host covers the game engine, testing strategies, and Rust development practices for building efficient contracts.

Anke Liu from the Stellar Development Foundation presented updates to the Stellar Community Fund, announcing a new four-week submission cycle for awards up to $150,000 XLM, a virtual startup bootcamp launching in April, and a tiered verified member system with governance roles.

SDF Q4 2022 quarterly review covering network growth to 7.4M accounts, Soroban smart contracts launching on FutureNet with mainnet planned for H1 2023, Stellar Aid Assist deployment in Ukraine, and the 2023 roadmap focused on utility as the growth exponent.

Soroban design discussion on Authnext proposal covering account abstraction, standardized signature payloads, and invocation authorization. Dima presented the two-component system enabling flexible authentication while maintaining protocol standardization for contract interoperability.

Soroban design discussion on Auth Next proposal covering account abstraction and standardized invocation authorization. The proposal aims to simplify authentication, enable complex multi-contract calls with single signatures, and support custom account implementations beyond classic accounts.

Sorbonne Talks stream featuring Stellar Development Foundation developers demonstrating Gitpod instant dev environment for Soroban smart contract development, showing how to build, test, and deploy contracts on Futurenet with minimal setup.

Raheem, a computer science student from Curacao, discusses his DAO smart contract submission to Soroban-a-thon. The contract uses reputation instead of tokens for governance, allowing members to create and vote on proposals that execute cross-contract instructions.

Stellar Development Foundation team discusses critical decision on how stellar assets are represented in Soroban: single balance approach (assets stored in trust lines, exposed via Soroban interface) versus dual balance approach (separate Soroban and classic balances). Community consensus strongly favors single balance for simplified user experience and ecosystem interoperability.

Stellar protocol discussion on CAP 46-06 covering the standardized token contract for Soroban smart contracts, including updates to token balances, naming conventions, clawback functionality, and solutions for handling auth-required assets from Stellar Classic.

Tomer from the Stellar Development Foundation announced Soroban, a Turing-complete smart contract platform native to Stellar, now live on FutureNet testnet. The SDF is allocating $100 million to support Soroban adoption and launched Sorobanathon First Light to reward developers building and providing feedback.
