The rapid development of computer technology in the 21st century has
led to the manifestation of sophisticated and intelligent threats that hinder further innovation. While the essence of cryptocurrency is decentralization, this has also become its greatest weakness. As the decentralized cryptocurrency system lacks a threat defense system, the burden for security has thus far been placed squarely upon the shoulders of individuals and corporations. Sentinel Protocol overcomes the disadvantage of decentralization by turning it into an advantage for security. By utilizing a collective intelligence system created through harnessing the power of decentralization, Sentinel Protocol combines cryptographic functions and intelligence-based threat analysis algorithms to create a secure, innovative ecosystem.
