Overview
PTERI assumes hostile networks and compromised servers, and eliminates whole classes of attack by removing their prerequisites.
Threats Eliminated
Why phishing, SIM swaps, database breaches, API key leakage and replay attacks fail structurally in PTERI instead of being mitigated.
Out of Scope
Physical device compromise, OS-level malware and social engineering are endpoint risks that PTERI does not claim to prevent.
Cryptographic Foundations
The primitives behind PTERI — secp256k1 signing, nonce-based challenge–response, Litecoin UTXO settlement and hash-based integrity.
Why Determinism Matters
PTERI asks only whether a cryptographic proof is valid, which makes verification predictable, auditable and safe for machines.
Security as Architecture
PTERI security comes from where keys live and what servers can do, not from policy, user education or trust in operators.
