Bitcoin, Ethereum steady; Stellar Protocol 26 and Hedera post-quantum upgrades advance blockchain tech

What shipped

Bitcoin continues to hold strong near the $75,000 mark, currently priced at $74,781 with a modest 0.2% increase over the past 24 hours. Ethereum is also showing healthy growth, up about 1% to $2,360. Beyond these well-known cryptocurrencies, several other blockchain projects are gaining momentum. Ripple’s XRP has risen by over 2.5%, reaching $1.40, while Stellar’s XLM increased nearly 2%, now at $0.158. Hedera Hashgraph and Flare Networks also posted notable gains with prices climbing close to 2% each.

On the technology front, Stellar recently released its Protocol 26 upgrade, known as the Stellar Yardstick. This upgrade improves network efficiency and supports new decentralized finance (DeFi) applications, making it easier for developers and institutions to build on Stellar’s blockchain. Meanwhile, Hedera Hashgraph is advancing its security with research and discussions around post-quantum cryptography—an emerging field aimed at protecting blockchain networks from future quantum computer attacks.

There’s also buzz around upcoming events like HederaCon 2026, where industry leaders will gather to discuss the latest innovations and roadmap for Hedera’s network. These developments highlight how these projects are not just maintaining their ecosystems but actively pushing forward with upgrades and community engagement.

Why it matters

For newcomers and investors alike, understanding why these updates matter can help make sense of the broader blockchain landscape.
