Abstract:
A ticket issuer server provides a digital instant lottery ticket, such as a smart contract instant lottery ticket (SILT) on a digital ledger, such as a blockchain infrastructure that supports execution of smart contracts. The ticket issuer server obtains an encryption key from a key issuer, encrypts a prize code with the encryption key to provide an encrypted prize code, creates an object, such as a smart contract representing the SILT, wherein the smart contract includes a ticket owner address attribute, a ticket issuer address attribute, a key issuer address attribute and the encrypted prize code, and stores the object on the digital ledger.
