Overview

Description

Kong is a physical crypto-cash system that combines physical notes with secure elements and time-locked smart contracts. The notes are made from space-age materials and are time-locked. They can be used like physical cash, with no transaction fees or paper trail. Kong aims to make crypto more accessible by providing a familiar cash-like experience. The system consists of a physical note with a secure element that generates a private key, and a time-locked smart contract that mints the Kong asset. The underlying crypto asset is claimable only after the note's expiration date and with a signature from the secure element. Before expiration, the notes can be exchanged freely, and the total supply can be audited.
