Let's say, 3 companies are using ethereum network.
- Company A
- Company B
- Company C
Company A put some data,
block02. So ethereum network looks like,
Genesis Block -> block01 -> block02
Now Company B put another piece of data
block03. So the chain looks like,
Genesis Block -> block01 -> block02 -> block 03
Here come the Company C and this company put
So finally the blockchain is like
Genesis Block -> block01 -> block02 -> block03 -> block04 -> block04
Am I right about the blockchain architecture?
Also, all the data stored in the block, are they visible to all? Can anyone check the data inside block in the ethereum network?
