SPoS's reliance on a reputation-based system introduces vulnerabilities absent from PoW and traditional PoS, most notably Sybil attacks, collusion risks, and reputation manipulation, which could undermine its decentralized governance and consensus if not robustly addressed.

However, its innovative reliance on a reputation-based system introduces vulnerabilities—most notably Sybil attacks, collusion risks, and reputation manipulation—that could undermine the integrity of its decentralized governance and consensus processes
