Stellar and Hedera Launch Upgrades to Enhance Security and Tokenized Finance

What Shipped

This month, several important updates and partnerships have been announced across some of the blockchain projects you may have heard about, including Stellar, Hedera, Ripple, Flare Network, and XDC Network. These projects are focused on improving blockchain technology, making it more secure, efficient, and accessible for everyone.

Stellar, a blockchain platform known for fast and low-cost cross-border payments, introduced the Quantum Preparedness Plan. This plan prepares the network for future threats from quantum computers, which could potentially break current encryption methods. By getting ahead of these challenges, Stellar aims to keep its network secure for years to come.

They also released the Stellar Zipper, Protocol 27 Upgrade Guide, which is a technical update to improve the network’s efficiency and introduce new features. This upgrade helps the network handle more transactions smoothly, which is great news for users and developers building on Stellar.

Hedera Hashgraph, another platform known for its fast and energy-efficient consensus technology, announced a partnership with Archax to advance tokenized securities. Tokenized securities are traditional financial assets like stocks or bonds that are represented digitally on a blockchain, allowing for faster and more transparent trading. This partnership introduces real-time streaming cash flows, meaning investors can receive payments continuously rather than waiting for periodic distributions.

Hedera also welcomed new strategic and community partners to its governing council, strengthening its network and expanding its reach. Additionally, they published insights on digital identity in the modern era, highlighting how blockchain can help individuals control their own personal data securely.

On the security front, Microsoft reported discovering malware that targets cryptocurrency wallets and spreads through USB sticks. This reminder highlights the importance of keeping your digital assets safe by using secure wallets and being cautious about the devices you connect to your computer.
