Scientific Paper NFT 📚

This repository contains a Solidity smart contract for creating and managing non-fungible tokens (NFTs) representing scientific papers. The contract is built using the Ethereum blockchain and leverages the OpenZeppelin ERC721 and Ownable contracts to ensure a secure and standard-compliant implementation.

🌟 Features

• Utilizes IPFS for decentralized storage of scientific papers.
• Enables submission, review, and approval of scientific papers in a decentralized manner.
• Mints unique NFTs for each approved paper.
• Utilizes OpenZeppelin ERC721 and Ownable contracts for secure implementation.

📜 Contract Overview

The ScientificPaperNFT contract defines a Paper struct that holds essential details, such as:

• IPFS hash for decentralized paper storage
• Editor's Ethereum address
• Two revisor Ethereum addresses
• Counter for tracking received approvals

The contract allows the contract owner to submit a new paper, which creates a new Paper struct and emits a PaperSubmitted event. Revisors or the editor can approve a paper, and once a paper receives two approvals, an NFT is minted for that paper. The contract uses events to track and notify users about paper submissions and approvals.
