An economic node in the Bitcoin network is crucial for ensuring the validity of transactions one receives.Nodes verify transactions by checking them against a complete set of existing coins in the UTXO set.The historical record of transactions in the blockchain must be processed to compute the UTXO set.Economic nodes are used by individuals engaged in economic activities to confirm received coins' validity.The coherence of the Bitcoin network relies on all nodes running the same consensus rules.Nodes deviating from consensus rules can impact economic interactions and market participation.Nodes with higher economic activity exert more influence on the network's consensus rules.Nodes with minimal economic activity have negligible impact on the overall Bitcoin network.Running a node solely for personal transactions verification has minimal effect on network consensus.Bitcoin's resilience against sybil attacks is attributed to the requirement of economic activity behind nodes.
