Without nodes, blockchain would lose its supposed advantages of transparency, security, and decentralization. Nodes are distributed across cities around the world and form the foundation of the chain. The more nodes there are, the more decentralized the network becomes and the more securely a public blockchain operates. Nodes maintain records, verify and broadcast data, and uphold distributed consensus. If nodes are missing or highly concentrated, the ledger is no longer independently maintained by multiple parties, the cost of tampering drops significantly, and its transparency—being public and traceable—also breaks down. The trust foundation of Web3 and the digital economy rests on a widely distributed network of nodes. Only when the node ecosystem is healthy and active can the value of decentralization truly be realized. #Web3 #Blockchain #DigitalEconomy#区块链分布式节点
