Most location systems still depend on signals from beacons, Wi-Fi, and anchors, but these signals can be spoofed or emulated, leading to a false sense of presence. The core problem is straightforward: a signal does not equal a fact. Proof of Presence addresses this by moving trust from raw signals to verifiable events. A validator layer ensures events are verified instead of blindly accepted, zero-knowledge proofs provide cryptographic verification rather than relying on signals alone, quorum signatures eliminate dependence on a single trust point, and nullifiers prevent replay attacks. As a result, even if the infrastructure is compromised, it cannot generate a valid event on its own. Proof of Presence turns presence into a verifiable truth rather than something assumed from a signal. #stonfi #web3 #cryptonews
