Blockchain is a distributed database in which many courts are maintained continuously, which are called blocks. Each block is linked to its previous block. If you have to change the data of a block, for this, you will have to change the data of all the subsequent blocks. That is why it becomes quite an impossible task for hackers. Also, one thing that makes it more powerful is its peer to peer network. The data that is inside the blockchain is not just inside your computer, it stays with you in the computers of multiple people, Which is connected through a peer to peer network. So if you have to change any data, then you have to change your computer as well as the rest of the computers. So hacking all the other computers is also an impossible task. The data once moved inside the blockchain cannot be changed again. And here you do not have to pay any transaction charge.
