I read different sourcing claiming the size of the blockchain for bitcoin.
Some says it's 8GB, some a 100GB and some 800GB.
Now I'm wondering do all the miners computers (nodes) have to store it all ? In case it's a TB it seems like a lot. Even though it's not it's still growing everyday, so is the blockchain really entierely stored on each nodes ?
Note : I used to mine a few years back I don't remember having my storage taken up by the blockchain.
