Lottery Smart Contract

The Lottery Smart Contract is a decentralized application (DApp) built on the PChain blockchain. It allows participants to purchase lottery tickets and have a chance to win the total prize. The contract randomly selects a winner when the number of participants reaches the targeted number.

Features

• Participants can enter the lottery by purchasing a ticket.
• The contract ensures that participants have sent the correct ticket price.
• The total prize increases with each ticket purchase.
• When the number of participants reaches the targeted number, the contract conducts the lottery and selects a random winner.
• The winner receives the total prize amount.
• The contract resets for the next lottery round.
