Catena Formerly (CORE MultiChain) is a PoS blockchain focused on Interoperability, Scalability, and Usability and Privacy.Catena provides advantages over existing and legacy blockchains such as sharding, simplistic blockchain creation and implementation, cross-chain capabilities, and high transaction throughput.Catena created a decentralized neighbor selection protocol that continuously strives to create optimal peer connections to decrease confirmation latency. The protocol achieves this through constantly analyzing and learning how nodes interact with their neighbors.How Does the Catena Attract People?

• Lightweight Compatible with the self-interests of each peer, or ability to select the best neighbors
• Robust against adversarial actions: A Catena peer does not need all details about a candidate neighbor to decide whether to connect Incentivizes peers to relay blocks promptly.
• Naturally adaptive to varying hash-power Catena is the next generation of blockchain protocol designed to enable legacy, current, and future blockchains to scale and communicate seamlessly. Catena offers a wide variety of possibilities in the blockchain space due to its sharding, interoperability, and central algorithm.By providing a fair and secure platform, Catena allows users to regain control over their personal information. The project offers a scalable network featuring functionalities that bypass current blockchain limitations. CORE intends to provide an environment-friendly system that is sustainable, interoperable and provides enhanced throughput.
