What is Blockchain? - Bitcoinist.net

The blockchain is essentially, you guessed it, a chain of blocks. But is much more than that. To put something in the blockchain is a digital equivalent of setting it in stone and digitally recording it forever.

You see, as previously mentioned before, the longer the blockchain is, the more work a miner will be required to do in order to change a single transaction. This made a very attractive for people that want to store data long term, as it’s very unlikely that it will be altered or otherwise changed.

The blockchain isn’t just set to storing transaction records. The blockchain enables a user to store any digital files including artwork, contacts, images, etc. The blockchain authenticates that a certain user is indeed the owner of your work and cannot be disputed.
