8.4 Verifiable Settlement

Once a signed transaction is submitted:

• It is broadcast to the Litecoin network

• It is validated by proof-of-work

• It becomes part of the public ledger

Settlement in PTERI is:

• Publicly verifiable

• Deterministic

• Non-reversible by intermediaries

Any party can independently verify:

• That the transaction exists

• That it was correctly signed

• That it was settled on-chain

There is no reliance on:

• Internal databases

• Custodial confirmations

• Trust in Kakr Labs infrastructure

The blockchain is the final arbiter.

How Payments and Identity Come Together

In PTERI:

• Payments are not separate from identity

• Identity is not verified by credentials

• Authorization is not implicit

Everything reduces to: UTXO + Signature + Verification

This allows:

• Human payments

• Machine-to-machine payments

• AI agent execution

• Global, automated settlement

All using the same primitive.
