Description: The transaction lifecycle refers to the stages a transaction goes through from its creation to its confirmation. This process is fundamental in systems that use consensus mechanisms, such as cryptocurrencies that implement proof of work or other blockchain technologies. Generally, the transaction lifecycle includes several key phases: creation, where the transaction is generated and sent to the network; propagation, in which the transaction is distributed among the nodes of the network; validation, where nodes verify the authenticity and validity of the transaction; and finally, inclusion in a block, which is the step where the transaction is confirmed and permanently recorded on the blockchain. This cycle is essential to ensure the integrity and security of transactions, as each stage involves controls and checks that prevent fraud and errors. The efficiency and speed with which this cycle is completed can influence user experience and the overall functionality of the system, making its understanding crucial for both developers and users.
