The root cause of network latency is that the maximum speed of information transmission is the speed of light, and the speed of light is limited. Therefore, achieving absolute consistency (certainty) in network consensus is impossible. This illusion of absolute consistency (certainty) is only established on the philosophical foundation of Newtonian information transmission at infinite speed (unlimited speed of light). This is also the fundamental difference in the core philosophical concepts between BTC and other altcoin public chains.
