#Kaspa is a high-performance decentralized Layer 1 blockchain project, known for its unique DAG (Directed Acyclic Graph) structure and GHOSTDAG consensus mechanism. Kaspa aims to provide faster transaction confirmation speeds than traditional blockchains (such as Bitcoin) while maintaining decentralization and security. Kaspa was created by Yonatan Sompolinsky, an Israeli computer scientist and one of the main researchers of the GHOSTDAG consensus mechanism.

Yonatan Sompolinsky's Background

• He is a PhD researcher at Harvard University, with in-depth research in distributed systems and blockchain consensus mechanisms.

• As early as 2013, he proposed the GHOST (Greedy Heaviest Observed Subtree) protocol, which was later adopted by Ethereum to improve blockchain efficiency. Sompolinsky's research has influenced Ethereum's consensus mechanism, and Vitalik Buterin mentioned GHOST as one of the viable scaling solutions in the Ethereum whitepaper.

• He has also participated in various academic research concerning blockchain scalability and security, providing theoretical support for Layer 1 and Layer 2 solutions.
