Astronomers discover largest superstructure in cosmos
A team of international astronomers has identified what is believed to be the largest known superstructure in the cosmos, a discovery that could reshape our understanding of outer space. According to the scientists on the team, the discovery was made by ROAST, a German-operated satellite telescope, and the superstructure has been named "Quipu." Quipu is estimated to span an astonishing 1.4 billion light-years in width and contains approximately 68 galaxy clusters. "If you look at the distribution of the galaxy clusters in the sky within a spherical shell, ranging from 416 to 826 million light-years, you immediately notice a massive structure that stretches from high northern latitudes to nearly the southern end of the sky," Hans Böhringer, the project leader, explained in a statement. This discovery surpasses the size of the Sloan Great Wall, a galaxy cluster that measured around 1.1 billion light-years in length and was discovered in 2003. Future Of Nasa's Mega Moon Rocket Appears In Doubt Following Major Boeing Announcement Scientists noted that the newly discovered structure resembles an ancient script, with long fiber strands woven throughout. This visual similarity led to its name "Quipu," which is derived from the Incan word for knot. The scientists also chose the name due to the European Southern Observatory in Chile playing a role in the discovery, which is near the former home of the Inca Empire. By detecting radiation emitted by the galaxy clusters, scientists were able to confirm the presence of at least four other superstructures nearby. These structures are thought to account for 45% of galaxy clusters, 30% of galaxies and 25% of the matter in the universe. "For a precise determination of cosmological parameters, we need to understand the effects of the local large-scale structure of the universe on the measurements," researchers stated.

The discovery is seen as a significant step forward in mapping out the multiverse but likely won't be the last time that a superstructure is article source: Astronomers discover largest superstructure in cosmos

Peercoin Foundation Completes Key Tech Enabling Private Off-Chain Smart Contracts
THE HAGUE, NETHERLANDS and SAN FRANCISCO - January 31, 2025 ( NEWMEDIAWIRE ) - The Peercoin Foundation today announced the successful implementation of the ROAST protocol, a key piece of infrastructure that enables off-chain transaction organization with on-chain settlement, maintaining the Foundation's ongoing mission to pave the way for Peercoin layer two. ROAST (Robust Asynchronous Schnorr Threshold signatures) is a cryptographic scheme that allows large groups of hundreds or thousands of participants to collaboratively sign a transaction off-chain, with only the final result being recorded on-chain. This approach reduces network congestion, lowers costs, and improves efficiency while providing better privacy than on-chain solutions. The ROAST protocol is one of the essential components of a larger technical stack being built around the cross-platform Peercoin Flutter Wallet. Specifically, implementation of the ROAST protocol directly allows for the formation of staking pools, federalized cross-chain bridges, side-chains and distributed Oracles. The overarching goal is to create an infrastructure based on the Peercoin Flutter Wallet, which would enable private off-chain smart contracts and scalable coordination mechanisms. With the completion of the world's first implementation of ROAST, the Foundation is moving closer to enabling more robust and decentralized financial tools within the Peercoin network. Technology like ROAST when integrated properly into user-facing applications, such as a mobile wallet, makes the blockchain technology human-meaningful and human-centric. About Peercoin Peercoin is the original Proof-of-Stake blockchain. It is a 12-year-old, fairly distributed, open-source, and community-driven project. Peercoin is designed around the concepts of energy and economical sustainability, both made possible by its innovation of Proof-of-Stake consensus. Peercoin is a peer-to-peer protocol in the truest sense because all coin owners have the power to run a full node, produce blocks, and earn Peercoin as a reward. Proof-of-stake is used for Peercoin's blockchain security, while proof-of-work is only used to distribute new coins for the purpose of creating a wider and fairer distribution. About Peercoin Foundation Development of the ROAST Coordinator, the Peercoin Flutter Wallet and other projects are sponsored by the Peercoin Foundation , a non-profit organization established in 2018 with the mission of promoting and supporting the continued development and overall progression of the Peercoin project. The Peercoin Foundation is sponsored solely from community donations. Please donate to the Foundation to enable it to help improve the general Peercoin ecosystem.
