| - | In many ways the full nodes' functionality is analogous to those of servers in decentralized networks. However, there is no centralized "truth" or final judge. Instead, the "truth" is determined by consensus among the full nodes. However, this consensus based methodology is not without its pitfalls. When more than 51% of the full nodes cannot reach consensus (i.e., agree with a transaction or a proposition), the proposed change is skipped. This can lead to a [[dido:public:ra:xapend:xapend.a_glossary:h:hard_fork]] in the ledger and the opposing groups diverge, creating two or more chains (( | + | In many ways, the full nodes' functionality is analogous to those of servers in decentralized networks.
