Nodes are not safe if they outsource values that contradict other nodes. Nodes lack liveliness when stuck on the way to agreement. The federated voting model plays a crucial role in getting nodes to agree on a declaration. The SCP is the implementation of the Protocol of the Byzantine Agreement Federated, which aims to minimize cases of blocked agreement and neutralize them through a voting system. The SCP protocol includes two primary sub-minutes, the nomination minutes and the voting minutes. “A protocol can only guarantee approval if the quorum slices represented by the Q function fulfill a quality of validity that we call quorum intersection.” The FBA model relies on individual nodes to choose their own sets of quorum slices, effectively allowing for the organic and decentralized formation of quorums based on individual choices, hence the name “federated.” When discussing security and vitality in the FBA protocol, we need to assess quorum intersections and disjudged quorums. This type of result is rare, as nodes are able to choose a set with other trustworthy nodes they want to be a part of. This subset of trusted nodes is called Quorum-Slice, a small part of the overall quorum, which must reach an agreement to close the Ledger (i.e. add a block of transactions to the global Ledger). Individual trust nodes convince each other of concordance within a quorum slic. As long as the quorum slices overlap, the network as a whole can quickly reach consensus. In practice, traditional non-federated Byzantine agreements require each node to participate in each transaction to obtain a quorum.

It`s like getting every mayor in the state to know that you`re about to plant a tree in your garden and get most of them to approve it. It is not necessary and it is a waste of time and resources for all. In BRAVO`s FBA system, each node can decide who it trusts and is part of its decision group, which we call Quorum Slice. According to the previous example, you just need to let your neighbors (your quorum round) know that you want to plant a tree in your garden and get them to consent to it. A quorum is the number of nodes needed to reach agreement within a system. FBAs use “Quorum Slices” instead. A quorum slice is a fraction of a quorum that can convince another particular node to accept. To avoid blocking agreements, nodes can interrupt some votes and move on to another. Conversely, nodes can vote to establish a ballot, which externalizes the value of that ballot to the consensual ballot. A quorum slice can convince a single node of approval, while a quorum convinces the entire compliance system….
