ICP Jackpot

It is a decentralized lottery system on the Internet Computer (ICP) blockchain, ensuring transparency, fairness, and security. Users purchase tickets, and a winner is randomly selected after each round, with the prize pool growing with each ticket sale. The system uses cryptographic methods for secure ticket handling and winner selection, and prizes are distributed in ICP tokens. Admin controls manage lottery resets, while blockchain immutability guarantees trust and fraud prevention.

A Transparent Lottery Built on ICP

ICP Jackpot is a decentralized lottery system built on the Internet Computer (ICP) blockchain, providing a fair, transparent, and secure environment for participants. The platform allows users to purchase lottery tickets during an open period, after which a winner is randomly selected using cryptographic methods. All activity—from ticket purchases to prize claims—is immutably recorded on-chain, ensuring transparency and eliminating centralized control or manipulation. Ticket IDs are encrypted to maintain user anonymity, and each purchase contributes directly to the growing prize pool.

Secure, Fair, and Efficient Lottery Lifecycle

Once the ticket purchase window closes, the lottery enters a closed state, and a winner is selected at random from the eligible ticket holders. The prize, paid in ICP tokens, must be claimed within a specified timeframe. If claimed, the lottery resets for a new round, reinitializing all key variables. Owner-controlled functions like reset ensure security and governance without compromising decentralization. Built using Calimero SDK, Borsh serialization, and SHA-256 encryption, ICP Jackpot combines powerful tools to deliver a seamless and trustless lottery experience for the community.

Ticketing & Prize Mechanics

🔹 Participants buy a limited number of tickets per round at a fixed price. Each ticket increases the prize pool, and ticket data is encrypted to ensure anonymity and fairness.

Lottery Lifecycle & Winner Selection

🔹 The lottery transitions from open to closed states. A random winner is selected from the ticket pool using cryptographic methods, and the winner must claim their prize within a set period.

Security, Technology & Control

🔹 Built with Calimero SDK and Borsh, the system uses SHA-256 for ticket generation and follows ICRC-1 token standards. Only the contract owner can reset the lottery, ensuring controlled and secure operations.
