Stellar advances quantum security and scalability; Hedera boosts tokenized securities with real-time payments

What shipped

June 2026 has brought several exciting updates and developments in the blockchain space, especially focusing on projects like Stellar, Hedera, Flare Network, Ripple, and XDC Network. These organizations continue to push forward with new technologies and partnerships that aim to make blockchain more accessible, secure, and useful for everyday users and businesses alike.

One of the standout updates comes from Stellar, which recently introduced the Quantum Preparedness Plan. This initiative aims to prepare the Stellar network for the future when quantum computers become powerful enough to potentially break current cryptographic security. By planning ahead, Stellar hopes to keep its network secure and trustworthy for users worldwide.

Alongside this, Stellar also rolled out its Protocol 27 Upgrade Guide. Protocol upgrades are like software updates for a blockchain — they improve performance, add features, or fix issues. This upgrade, called “Stellar Zipper,” focuses on enhancing the network’s efficiency and scalability, which means it can handle more transactions faster and at lower costs.

Meanwhile, Hedera Hashgraph has made strides in the tokenized securities space through a partnership with Archax. Tokenized securities are traditional financial assets, like stocks or bonds, represented digitally on a blockchain. This partnership enables real-time streaming of cash flows, meaning investors could receive payments continuously rather than waiting for monthly or quarterly dividends. This is a significant step toward modernizing how financial markets operate.

Hedera also welcomed new strategic and community partners, strengthening its governance and expanding its ecosystem, as detailed in their recent blog post. This kind of collaboration helps improve the network’s security and adoption.

On the payments front, a new company called GoMining is challenging Jack Dorsey’s Square by building a payment system designed specifically around Bitcoin. This could offer an alternative way for merchants and customers to transact using the world’s most popular cryptocurrency.

Additionally, Franklin Templeton, a well-known asset management firm, proposed new exchange-traded funds (ETFs) that convert corporate dividends into Bitcoin. This innovative approach could make it easier for traditional investors to gain exposure to Bitcoin without directly buying or managing the cryptocurrency themselves.

Why it matters

These developments highlight a few important trends shaping the blockchain landscape:

• Security and future-proofing: Stellar’s Quantum Preparedness Plan shows the importance of anticipating future technological challenges, like quantum computing, to keep networks safe.
• Efficiency and scalability: Upgrades like Stellar’s Protocol 27 make blockchains faster and cheaper to use, which is essential for mainstream adoption.
• Integration with traditional finance: Hedera’s work with tokenized securities and Franklin Templeton’s Bitcoin ETFs bridge the gap between old and new financial worlds, making blockchain more accessible to everyday investors.
• New payment solutions: GoMining’s Bitcoin-focused payment system offers fresh competition and innovation in how cryptocurrencies can be used in daily commerce.

For newcomers, these stories show that blockchain technology is not just about speculation or digital coins — it’s actively evolving to solve real-world problems, improve financial systems, and prepare for future challenges.

Builders’ corner

If you’re interested in the technical side or considering getting involved, here are some concrete examples of what builders and developers are working on:

• Quantum-resistant cryptography: Stellar’s team is exploring new encryption methods that can withstand attacks from future quantum computers. This is a cutting-edge area that combines cryptography with blockchain.
• Protocol upgrades: Developers on the Stellar network are continuously refining the consensus mechanism and transaction processing to handle more users and lower fees.
• Tokenized assets and real-time payments: Hedera is building infrastructure to allow digital tokens representing stocks or bonds to pay out dividends instantly and continuously, which could revolutionize income streams for investors.
• Bitcoin payment systems: GoMining is developing tools that integrate Bitcoin smoothly into everyday payments, focusing on speed and user experience.

For beginner developers, many of these projects offer open-source codebases and active communities where you can learn and contribute. Whether you want to build decentralized apps, improve blockchain protocols, or create new financial products, there’s a welcoming space for you.

Quick prices

As of June 19, 2026, here are some key cryptocurrency prices and their 24-hour changes to give you a snapshot of the market:

• Bitcoin (BTC): $62,920 (+0.7%) — Bitcoin remains the leader and a popular store of value.
• Ethereum (ETH): $1,695 (+0.8%) — Known for smart contracts and decentralized apps.
• Flare Network (FLR): $0.0074 (+0.67%) — A platform aiming to bring smart contract functionality to other blockchains.
• Hedera Hashgraph (HBAR): $0.080 (+1.4%) — Focused on fast, secure enterprise blockchain solutions.
• Ripple (XRP): $1.13 (-1.4%) — Popular for cross-border payments, though facing some recent price pressure.
