The Stellar Development Foundation outlines seven current and upcoming developer programs for Soroban, ranging from content bounties and hackathons to educational challenges and coding puzzles, with awards up to $150,000 XLM for builders creating end-to-end products.

This article explains the Stellar Consensus Protocol (SCP), a Proof-of-Agreement mechanism that enables Stellar to achieve fast, energy-efficient consensus without mining. It compares SCP to other consensus mechanisms like Proof-of-Work and Proof-of-Stake, and details how Stellar's transparent, node-based validation process works.

This article outlines the essential building blocks required for a thriving smart contract ecosystem on Soroban, including financial protocols (AMMs, lending markets), data access tools (oracles, indexers), user interfaces (wallets, block explorers), and security mechanisms. It demonstrates how these interconnected components enable real-world DeFi use cases like decentralized lending.

GetPaid is a Stellar-powered marketplace connecting African digital professionals with global companies, enabling fast cross-border payments in multiple currencies. Built on Stellar's Anchor platform, it addresses talent supply challenges while providing cost-efficient payment solutions for freelancers and creators across Kenya, Rwanda, and Tanzania.

Félix, a WhatsApp-based remittance platform, partners with Bitso to enable faster and cheaper cross-border payments from the US to Latin America using USDC on the Stellar network. The solution reduces remittance times from hours or days to seconds while dramatically lowering transaction fees.

MoneyGram International has launched MoneyGram Ramps, a cash-to-crypto on and off-ramp service powered by the Stellar blockchain and USDC stablecoin. The service enables unbanked and underbanked populations to convert physical cash to digital assets at MoneyGram's 480,000+ locations worldwide, addressing the critical last-mile problem in blockchain adoption.

An educational overview of blockchain fundamentals, explaining how distributed ledgers work, their advantages over centralized databases, and comparisons of major blockchain platforms including Bitcoin, Ethereum, and Stellar.

Arf, a regulated liquidity and settlement platform, leverages the Stellar network and USDC to provide cross-border payment solutions for financial institutions. By eliminating pre-funding requirements and enabling same-day settlements, Arf has extended over $830 million in loans with $1.6 billion in on-chain transaction volume since 2022.

Kazim Ozyilmaz from Arf discusses how the Swiss-regulated settlement banking platform uses Stellar for cross-border B2B financing and liquidity, operating as a meta anchor for financial institutions with DeFi integration planned.

This article explains the role of lumens (XLM), Stellar's native token, in the network's design. Lumens serve as a modest barrier to prevent spam and abuse while keeping the network accessible, with a minimum balance requirement of 1 lumen and transaction fees of 0.00001 XLM.

Vesseo is a wallet app built on Stellar by Sunship, Inc. (a Stellar Development Foundation subsidiary) that enables Argentines to easily purchase and hold USDC stablecoins to protect against peso inflation. The app leverages Stellar's speed, low fees, and integrations with anchors like Settle and Circle to provide a simple user experience for accessing dollar-backed value.

A comprehensive guide to Rust development for smart contracts on Soroban, covering setup, language advantages over Solidity, and resources from the Stellar Development Foundation for learning and building.

The Stellar Development Foundation shared progress on Soroban's Minimum Viable Ecosystem, outlining priority building blocks like financial primitives, data tools, and wallets needed before mainnet launch this fall. The foundation is actively funding projects through the Stellar Community Fund and inviting developers to help shape the platform.

Bitso integrated Stellar's Anchor Network to enable USDC payments to Argentina, Colombia, and Mexico, leveraging blockchain to improve cross-border settlement times and costs for businesses and remittances.

The Stellar Development Foundation's Twitter account was compromised via SIM swap attack on July 8, 2023, used to spread phishing scams. SDF regained control within 6 hours and upgraded security protocols across all platforms to use stronger authentication methods like security keys.

This article explores the various consensus mechanisms available in Hyperledger Fabric, including PBFT, Kafka, Raft, Solo, and IBFT. It details their characteristics, use cases, and how they integrate with Fabric's architecture like ordering services and endorsement policies. A brief mention of Stellar Consensus Protocol (SCP) appears in the context of external consensus integration.

Aquarius announces participation in Stellar Community Fund round 15 to develop Soroban-powered AMMs on the Stellar network. The project aims to create Uniswap v2-style smart contracts, advanced AMM types, and AQUA reward distribution on Soroban futurenet. This builds on Aquarius' established liquidity incentivization system, which has distributed over $2.25M in rewards.

Soroban implements state expiration to address blockchain state bloat, becoming the first blockchain to deploy this solution at mainnet launch. The design includes an Expired State Store, two storage types (Temporary and Persistent), and a rent model to prioritize important data and improve network scalability.
