Anyone here understand how nodes work and the operations surrounding them? Just curious not sure if this is the right place to post or not.
Any specific question you have?
It is just about relaying a blockchain and unconfirmed transactions. That is pretty much their job.
Not so. Nodes
validate the data they receive against consensus rules. That is the most important part of a node’s job.
Nodes are responsible for securing the validity of the network, as well as the validity of their own databases. That is why running your own full node is the most secure way to use Bitcoin—really, the
only secure way.
To fill out this explanation, miners have one and only one function: To determine the
ordering of transactions in a Byzantine fault-tolerant distributed database with no central authority. That is what miners do. That is
all miners do. Granted, it is a very valuable function; that is why they get paid for it. But all other functions in the security and validity of the network are done by nodes. The nodes’ responsibility includes enforcing validity of blocks, in case miners create invalid blocks. Nodes do not follow the chain with the most proof-of-work: They follow the
entirely validated and valid chain with the most proof-of-work.
