In a recent email exchange between Zac Greenwood and Eric Voskuil, the topic of whether a node enforces consensus rules in Bitcoin was debated. Voskuil argued that it is up to economic nodes, people who refuse to accept invalid money, to enforce consensus rules. Greenwood disagreed, stating that nodes do enforce consensus rules by disregarding invalid transactions and blocks. He provided examples from the BCH split to support his argument. The debate continued with Greenwood asserting that non-economic nodes are ignored by the network, while Voskuil emphasized the role of merchants in enforcing consensus rules.Another discussion focused on the relationship between game theory and Bitcoin. Voskuil expressed skepticism regarding the relevance of game theory to Bitcoin, stating that he has not seen any demonstration of their connection. He also clarified that mining pools and exchanges do not necessarily discuss before signaling for a soft fork. Miners can mine whatever they want and earn block rewards. Voskuil further explained that consensus rules are enforced by merchants who reject trading for something they don't consider money. The conversation highlighted the misunderstanding of signaling as voting and emphasized the complexity of enforcing consensus rules.Further discussions explored the enforcement of consensus rules in the Bitcoin network. One participant argued that it is ultimately up to individuals to enforce the decision to reject invalid transactions, while another participant asserted that nodes definitely enforce consensus rules and define what Bitcoin is. The conversations also touched on topics such as chain splits, soft fork signaling, and the role of miners. The participants offered different perspectives, highlighting the complexity and differing viewpoints surrounding the enforcement of consensus rules.Voskuil responded to questions related to Bitcoin's consensus rules and mining, noting that two people on different rules imply a chain split. He highlighted the absence of a concept of "the rules" and questioned why miners would mine a chain that nobody wants to use. Voskuil expressed uncertainty about the relevance of game theory to Bitcoin and clarified that a node does not enforce anything. He emphasized the role of merchants in enforcing consensus rules and addressed misconceptions about soft fork signaling. Voskuil stated that miners mine whichever chain they want and earn block rewards, and that signaling is not equivalent to voting.In summary, the discussions revolved around the enforcement of consensus rules in the Bitcoin network. While there were differing opinions, it was acknowledged that both nodes and merchants play a role in enforcing these rules. The complexity of enforcing consensus rules, the relevance of game theory, and the misconceptions surrounding soft fork signaling were also highlighted. Ultimately, the conversations showcased the multiple perspectives and challenges associated with maintaining consensus in the Bitcoin network.
