Why Blockchain?

Blockchain

A Blockchain is a "chain of blocks" that build upon each other and store information. The most well-known application is Bitcoin. Two individuals exchange money for goods over the internet without involving a third party. This was first explained in the Bitcoin whitepaper. 

Transactions

JEach block contains information about assets and an exchange at a specific time, known as "transactions." The information is stored simultaneously across multiple nodes in the blockchain network.

Wallets and Private Keys

Ownership is represented in wallets (digital wallets). Each wallet has an address, similar to an email address. Only the owner possesses a secret key that allows transactions to be made from the wallet.

NFTs

A NFT ("non-fungible token") is a unique digital asset or certificate. Its authenticity is ensured through cryptographic methods of blockchain technology. Students store certificates in their wallets.

We use blockchain technology to store certificates independently of time and location, without reliance on technology, computers, or electricity. Theoretically, one can write down the addresses of a wallet and the keys on a piece of paper.
