How does an Ethereum node understand that 51% confirmations have been obtained?
In a private Ethereum setup:
- How does a node that computed the nonce understand that 51% of the nodes have confirmed the mining?
- Is there some kind of a counter maintained which shows number of confirmations?
- Are the nodes which confirmed the mining rewarded with some amount of Ethers?
- Does a node confirmation mean that along with confirming the nonce, all the transactions in the block are also confirmed?
