Picture of blockchain Can anyone point me to the picture I saw somewhere but can not find it anymore where blockchain is represented as a line of blocks chained together. There was a locker on each little block, and each block was chained to the next one.
The blocks were forming something like a line/queue of blocks
I'm googling for an hour now and can not find it anymore

UPDATE 1

Here is a sketch of what I had in mind.
I'm sure I saw it somewhere but it might have been in a video about blockchain.

 

And then the block chain was like a very long (infinite) line of blocks
