Stellar advances quantum security and scalability; Hedera innovates tokenized securities and identity

What Shipped

June 2026 has been an exciting month for blockchain enthusiasts and investors alike, with several key projects making important progress. Notably, Stellar has been busy rolling out major updates, including the release of their Quantum Preparedness Plan. This plan aims to prepare the Stellar network for future quantum computing threats, ensuring long-term security of their blockchain.

Alongside this, Stellar also launched the Protocol 27 Upgrade Guide, known as Stellar Zipper. This upgrade improves the network’s efficiency and scalability, making transactions faster and cheaper for users.

Meanwhile, Hedera Hashgraph continues to advance tokenized securities with its partnership with Archax, bringing real-time streaming cash flows to the market. This innovation allows investors to receive dividend-like payments continuously rather than in lump sums, a major step forward for decentralized finance (DeFi).

Hedera also welcomed new strategic and community partners, expanding its ecosystem and strengthening governance. Their focus on identity solutions is highlighted in their recent blog Identity in the agentic era, emphasizing secure and user-controlled digital identities.

On the security front, artificial intelligence (AI) is increasingly being used to enhance crypto security, making it more affordable, faster, and reliable, as detailed in a recent Coindesk article. This trend promises to protect investors and projects from hacks and fraud more effectively.

Why It Matters

These developments highlight a maturing blockchain ecosystem that is focusing not just on growth, but on sustainability, security, and real-world usability.

• Quantum Preparedness: Quantum computers could one day break current cryptographic protections. Stellar’s plan to prepare for this ensures your transactions and assets are safe far into the future.
• Protocol Upgrades: Faster and cheaper transactions on Stellar mean more people and businesses can use blockchain technology without high fees or delays.
• Tokenized Securities: Hedera’s real-time streaming cash flows bring traditional finance features to the blockchain, making investments more flexible and transparent.
• Identity Solutions: Secure digital identity is key to privacy and trust online. Hedera’s work here could impact everything from finance to healthcare.
• AI in Security: Using AI to monitor and protect crypto systems helps prevent losses and builds confidence among investors.

Builders’ Corner

If you’re a developer or someone interested in building on these networks, now is a great time to dive in:

• For Stellar: Explore the Protocol 27 upgrade to see how you can create faster payment apps or decentralized exchanges. The Quantum Preparedness Plan also opens opportunities for research and development on quantum-resistant algorithms.
• For Hedera: The partnership with Archax shows growing demand for tokenized securities. Builders can create new financial products that leverage real-time streaming payments, offering innovative options for investors.
• Security and AI: Consider integrating AI-powered security tools into your blockchain applications to offer users safer experiences.
