This study explores a simple ternary (-1, 0, +1) majority vote model. Starting from a checkerboard initialization (+1 where i+j is even, -1 otherwise), the system spontaneously emerges a stable zero-state fraction of approximately 4.5% without any pre-specified global rules, and this fraction is independent of system size. Through systematic parameter scanning, we discover two continuous phase transitions: (1) Percolation transition driven by self-protection attraction between zero-states, criti
