Stellar’s Protocol Upgrade and Hedera’s Quantum Security Mark Key Blockchain Advances

What Shipped

In the world of blockchain and cryptocurrency, the past week has brought several important updates and newsworthy developments, especially around some well-known projects like Stellar, Hedera, Ripple, Flare Network, and XDC Network. These projects continue to push the boundaries of what blockchain technology can do, focusing on improving speed, security, and usability for both individuals and institutions.

Here are some key highlights:

• Stellar’s Protocol 26 Upgrade: Stellar has released a detailed guide about their latest protocol upgrade, called “Stellar Yardstick.” This upgrade improves the network’s performance and adds new features that make it easier to build decentralized finance (DeFi) applications on Stellar.
• Hedera’s Focus on Post-Quantum Security: Hedera has published insights on post-quantum cryptography, which is an advanced form of encryption designed to protect blockchain networks against future quantum computers. This is a big deal because quantum computers could potentially break current encryption methods.
• Upcoming HederaCon 2026: Hedera’s annual conference agenda is now live, promising exciting talks and workshops that will showcase the latest innovations on their platform.
• Ripple and Stellar in the Spotlight: Both Ripple and Stellar continue to be in the news for their efforts to improve cross-border payments and institutional adoption of blockchain technology.

Why It Matters

Blockchain technology is still evolving, and while many projects have shown promise, most blockchains haven’t yet fully met the needs of large institutions like banks or governments. A recent article on Stellar’s blog explains why many blockchains struggle to serve these institutions effectively and what can be done to fix those issues. This is important because institutional adoption could bring more stability, trust, and widespread use of cryptocurrencies and blockchain solutions.

For example, faster and cheaper cross-border payments—one of the main goals of Ripple and Stellar—can revolutionize how money moves globally, reducing costs and delays that are common today. Hedera’s focus on post-quantum cryptography shows forward-thinking in securing blockchain networks for the future, which is crucial for long-term trust and safety.

In addition, DeFi (decentralized finance) continues to grow on platforms like Stellar, opening new financial opportunities without relying on traditional banks. This democratizes access to financial services, especially in underserved regions.

Builders’ Corner

If you’re curious about building on these platforms or just want to understand the technology better, here are a few concrete examples and simple definitions:

• Protocol Upgrade: This is like a software update for a blockchain network. It can improve speed, add features, or fix problems. Stellar’s Protocol 26 upgrade helps developers create better DeFi apps.
• Post-Quantum Cryptography: A new kind of encryption designed to keep data safe even against powerful quantum computers. Hedera is working on integrating this to future-proof their network.
• Decentralized Finance (DeFi): Financial services like loans, trading, and savings that don’t rely on traditional banks but run on blockchain networks instead. Stellar is actively improving its platform to support more DeFi projects.
• Cross-Border Payments: Sending money between countries. Ripple and Stellar focus on making these transactions faster and cheaper using blockchain technology.

For developers and entrepreneurs, these updates mean better tools and more secure environments to build innovative applications that could change how we interact with money and data.

Quick Prices

Here’s a snapshot of how some popular cryptocurrencies are doing as of April 12, 2026, 21:03 ET:

• Bitcoin (BTC): $71,194 (down about 2.57% in the last 24 hours)
• Ethereum (ETH): $2,205.95 (down about 3.46%)
• Flare Networks (FLR): $0.00776 (down about 1.93%)
• Hedera Hashgraph (HBAR): $0.0856 (down about 3.26%)
• Ripple (XRP): $1.33 (down about 1.84%)
• Stellar (XLM): $0.151 (down about 1.86%)
