This article discusses the controversy among Bitcoin developers regarding changes to node policies and the potential impact on the network. As a decentralized system, Bitcoin relies on global nodes to reach consensus to maintain the synchronization and security of the blockchain. Currently, some developers propose preventing spam transactions and improving block efficiency by increasing the minimum transaction fees or restricting certain types of transactions, but this proposal has caused divisions within the community. Supporters argue that this is a necessary measure to protect the network, while opponents worry that it will stifle innovation and lead to network splits. The article analyzes the two possible outcomes: soft forks and hard forks. A soft fork can upgrade smoothly with the consensus of the majority of nodes, while a hard fork may lead to a split in the Bitcoin network, affecting market confidence and price stability. Given Bitcoin's enormous market value and widespread attention, if the controversy over protocol upgrades becomes public, it may trigger severe market fluctuations. Therefore, continuously monitoring the dynamics of Bitcoin protocol upgrades is crucial for investors and holders.
