Stellar expands globally; Hedera adds MEV-resistance; Chainlink boosts privacy and DeFi security

What shipped

This week in the blockchain world, several exciting updates and developments have come to light, particularly from networks like Stellar, Hedera Hashgraph, and Chainlink. Stellar, a blockchain platform known for fast and affordable cross-border payments, shared multiple updates about its growth and regional expansion. Their recent blog posts highlight how they’re bringing their technology to key regions around the world, a move that could help increase adoption and real-world use cases.

On the Hedera Hashgraph front, the team has been focusing on improving security and scalability. One notable update is their push for “MEV-resistance.” MEV stands for Miner Extractable Value, which refers to the ability of miners or validators to reorder transactions for their own profit, sometimes at the expense of regular users. Hedera’s efforts to resist this practice are important because they help make the network fairer and more trustworthy, especially for institutional users who demand strong security guarantees.

Chainlink, a decentralized oracle network that connects smart contracts to real-world data, has been busy with privacy enhancements and major migrations. Their latest updates show how they’re bringing privacy features to blockchains, which is a big deal for users and businesses that want to keep sensitive information secure while still leveraging blockchain advantages. Additionally, Chainlink recently completed a migration moving over $4 billion in decentralized finance (DeFi) value to a new, more secure infrastructure, reinforcing their role as a backbone for many DeFi applications.

Why it matters

These updates matter because they address some of the biggest challenges and opportunities in blockchain today: adoption, security, privacy, and scalability.

• Stellar’s regional focus means more people and businesses in important markets will have access to fast and cheap blockchain payments, which can help drive real-world use of cryptocurrencies.
• Hedera’s MEV-resistance tackles fairness and trust, especially critical for institutional investors and enterprises who need reliable systems that protect them from unfair transaction practices.
• Chainlink’s privacy features open the door for sensitive data to be used safely on blockchains, expanding use cases in healthcare, finance, and beyond.
• The migration of billions in DeFi value to more secure infrastructure shows confidence in the technology and helps protect users’ assets, encouraging more participation in decentralized finance.

Additionally, Ripple and XDC Network continue to be important players in the blockchain space, focusing on fast, efficient transactions and enterprise-friendly solutions.

Builders’ corner

For developers and those interested in building on blockchain, here are some key takeaways and opportunities:

• Stellar’s network improvements mean more tools and support for developers who want to create applications that can reach new regions and users. Check out their recent blog posts for insights on scaling and execution at network level: Q1 2026: Execution at network scale.
• Hedera’s HIP-1313 proposal</strong introduces a “High-Volume Lane for Entity Creation.” This means developers can create and manage many entities (like user accounts or digital assets) more efficiently, which is great news for apps expecting large user bases or lots of activity. More details here: HIP-1313 details.
• Chainlink’s privacy tools</strong can be integrated into smart contracts to keep data confidential while still enabling powerful decentralized applications. This is especially useful for businesses that need compliance with data protection regulations.
• Ripple and XDC Network</strong continue to develop solutions that make cross-border payments faster and cheaper. Builders interested in financial applications should watch these networks for new APIs and developer programs.
