3.1 The Core Mental Model
PTERI is intentionally built on five strict rules.
These rules are not guidelines.
They are constraints.
They limit what the system can do — and that is what makes it secure.
Rule 1 — Wallet = Identity
In PTERI, identity is not an account.
There is no:
- Username
- Email-based identity
- Database-backed user record
Identity exists only as a wallet.
If you control the wallet, you are the identity.
Lose access to the wallet, and the identity is gone — just like losing a physical key.
There is no backdoor recovery by Kakr.
Rule 2 — Private Key = Authority
Authority is not granted by servers.
Authority is not assigned by roles.
Authority is proven by private key control.
If you can sign, you have authority.
If you cannot sign, you do not.
This rule eliminates:
- Privilege escalation
- Implicit trust
- Admin overrides
Rule 3 — Signature = Intent
A signature in PTERI is not a login artifact.
It is a statement of intent.
When a wallet signs something, it means:
“This authority approves this exact action, at this time.”
Because signatures are:
- Cryptographically bound to the message
- Non-replayable
- Verifiable by anyone
Intent becomes provable, not assumed.
Rule 4 — Litecoin = Verification & Settlement
Litecoin plays two roles in PTERI:
- Verification layer
- Settlement layer
It provides:
- A public, immutable record
- A global ordering of events
- Proof-of-work security
- Optional privacy via MWEB
Litecoin is not used for:
- Identity storage
- Metadata broadcasting
- Smart contract logic
Litecoin is the system’s public clock and court of record.
Rule 5 — Server = Verifier, Not Custodian
Servers in PTERI are deliberately constrained.
They may:
- Issue challenges
- Verify signatures
- Observe blockchain state
- Enforce rate limits and policies
They may never:
- Hold private keys
- Sign on behalf of users
- Recover identities
- Move funds
If a server can steal, the system is broken.
PTERI prevents this structurally.

🚫 No Alternate Trust Paths
There are no fallback mechanisms such as:
- Email recovery
- SMS overrides
- Manual admin resets
- Secret API keys
Every action flows through the same path:
Wallet → Signature → Verification
