Quorums – A quorum is a group of parties and entities that can vote on something, with every member being allowed to vote, with majority being reached with a 51% or higher vote. With quorums, a central concept is the idea that, “something either got the majority of votes or not, there should be nothing in between.” The concept of quorums have existed long before crypto, in other governance-based structures and bodies throughout history. For instance, the Senate of the Roman Empire utilized quorums in their proceedings, just as the modern day U.S. Senate uses quorums too – albeit in different ways.
Confirmations – This is a measurement of how many blocks of transactions miners have published since a transaction was added to the blockchain. Confirmations prove and verify that the transactions added to the blockchain are legitimate. Every additional block added to the blockchain provides greater security, since more confirmations make transactions more difficult for miners to modify. Thus, multiple confirmations add more security, but also take more time.
