3. Blockchain Visualisation

A decentralized platform web application based on the Ethereum blockchain, a block explorer of the Ethereum blockchain, and it contains the same functions as in the Dapp. By using programmed smart contracts, it ensures privacy(personal medical data) and there is no cheating on the platform, third party is restricted from viewing the content of the NFT tokens.

Besides, it allows users to check on their own NFT tokens, and easily search and browse the transactions and blocks. It can provide information about each transaction, such as the hash, timestamp, transaction event and token ownership. Additionally, it will display the addresses of both the sender and receiver in each transaction, which secures authenticity on the blockchain.
