Forward compatibility means that the new version of the blockchain system can process data from the old version, thereby ensuring the integrity and continuity of historical data. This is crucial for maintaining the stability and trustworthiness of the blockchain network. Backward compatibility refers to the ability of the new version of the blockchain system to be compatible with the old version of the node, allowing the old version of the node to participate in the operation of the new version of the network. This ensures a smooth transition between the new and old versions of the blockchain network, reducing the risk of network splitting.↵↵At the same time, forward compatibility and backward compatibility contribute to promoting the development  and application of blockchain technology. By ensuring the continuity of historical data and the stability of the network, blockchain projects can build a solid foundation for broader application scenarios and increased adoption. Moreover, backward compatibility"}]}],"pr":"c9ec515428b9d73c00ce3e04b2739dc4d61f1058963663b4ffbc6806efbc61f7"}
