Blockchain technology is like a digital ledger that keeps track of transactions in a secure and transparent way.
Instead of storing this information in one central place, airdrops it's spread across a network of computers, airdrops making it harder for anyone to tamper with. Each transaction is grouped into a "block," and these blocks are linked together in a "chain." Once a block is added, it can't be changed, thanks to special cryptographic techniques.

This setup makes blockchain very secure and trustworthy. If you're interested in using blockchain for your project, you might want to hire a blockchain developer or work with a blockchain development company to get expert help in setting it up.
