Stellar Advances Sovereign Currencies On-Chain; Chainlink Launches DataLink Product

What Shipped

October 2025 has been an exciting month in the blockchain space, with several important updates and developments across multiple projects. One of the standout stories comes from the Stellar ecosystem, where a new podcast episode highlights the ambitious Etherfuse project. This initiative aims to bring 100 sovereign (national) currencies onto the blockchain, making it easier and faster to transact internationally with digital versions of real-world money.

In parallel, Stellar also released their Protocol 24 Upgrade Guide, offering developers and network participants clear instructions on how to upgrade the network safely. Protocol upgrades like this one improve security, speed, and new features on the Stellar blockchain.

Another highlight is the Stellar i³ Awards 2025, which celebrate projects and developers building innovative solutions on the Stellar network. These awards help spotlight creative ideas and encourage further growth in the ecosystem.

Beyond Stellar, Chainlink, a decentralized oracle network that connects blockchains to real-world data, shared its Q3 2025 Quarterly Review and announced winning the Swift Hackathon 2025 Business Challenge. Chainlink also introduced DataLink, a new product to bring institutional market data directly on-chain, which is a big step for finance-focused blockchain applications.

On the regulatory and legal front, some significant news includes an Indian judge halting WazirX’s plan to reallocate XRP tokens linked to a 2024 hack, and the Mt. Gox bankruptcy case being delayed until October 2026 for creditor repayments. These updates remind us that the blockchain industry continues to navigate legal challenges while maturing.

Why It Matters

Bringing sovereign currencies on-chain, as Etherfuse aims to do, is a game-changer for global finance. Imagine being able to send money internationally in seconds with minimal fees, without relying on banks or traditional payment systems. This can increase financial inclusion, especially in countries where access to banking is limited.

Protocol upgrades like Stellar’s Protocol 24 are essential because blockchain networks need regular improvements to stay secure and efficient. When a network upgrades smoothly, it shows maturity and reliability, which builds investor and user confidence.

Chainlink’s advancements in connecting real-world data to blockchains open the door for more complex and useful decentralized applications (dApps). For example, with DataLink, financial institutions could automate trading or risk management using trusted market data, all on blockchain networks.

Legal developments, such as the court ruling in India and the Mt. Gox delays, highlight the ongoing intersection of blockchain technology with regulation and justice systems. While these events may cause short-term uncertainty, they also demonstrate that the industry is evolving with clearer rules and protections for users.
