Stellar’s Quantum Plan and Hedera’s Streaming Cash Flows Mark Key Blockchain Advances

What Shipped

June 2026 has been an exciting month in the blockchain space, especially for projects like Stellar, Hedera, Ripple, Flare Network, and XDC Network. Several important updates and collaborations have been announced that highlight how these networks are evolving to meet the needs of users and businesses worldwide.

One of the standout developments comes from the Stellar Foundation, which recently introduced the Quantum Preparedness Plan. This plan outlines how Stellar is preparing its blockchain to remain secure and efficient even as quantum computing technology advances. Quantum computers are powerful machines that could potentially break current encryption methods, so being prepared is key to protecting digital assets in the future.

Additionally, Stellar rolled out the Stellar Zipper Protocol 27 Upgrade. This upgrade improves the network’s speed and reliability, making transactions faster and more affordable for users. The upgrade guide helps developers and node operators understand the changes and smoothly transition to the new protocol.

Hedera Hashgraph, another fast-growing network, announced a significant collaboration with Archax, a regulated digital securities exchange. Their partnership focuses on advancing tokenized securities with real-time streaming cash flows. This means investors can receive payments continuously rather than in lump sums, which could transform how dividends and interest payments work in the digital asset world.

Hedera also shared news about welcoming new strategic and community partners to its council, further strengthening its governance and expanding its ecosystem. Plus, they published thought leadership on digital identity in the new “agentic era,” which explores how individuals can control their personal data securely using blockchain technology.

On the other hand, Flare Network experienced a slight price dip recently, but the team continues pushing forward with its vision of bringing smart contract capabilities to networks like XRP and Litecoin. Meanwhile, XDC Network, focused on enterprise blockchain solutions, maintains steady growth and adoption.
