What is blockchain ? Explained in 1 minute with fantastic animation

[0:00]Day one of chain insights making you better in web 3. In just 60 seconds, let's learn what is a blockchain. Imagine a digital ledger that everyone can see, but no one can alter. Blockchain is often described as a digital ledger, but what sets it apart is how it's maintained. Instead of one centralized ledger, blockchain is decentralized and copies of the ledger are stored on thousands of computers called nodes all around the world. Each block in the chain contains a list of transactions. Once a block is added, it's linked to the previous block, creating a chain that's immutable. This immutability means that once data is recorded, it can't be altered or deleted without altering every subsequent block, which is nearly impossible. This ensures security, transparency and trust. And this why blockchain technology is the foundation of cryptocurrencies, smart contracts and decentralized applications. Have you learned it? Don't forget to follow.
