What is a characteristic of the lifecycle of a transaction in blockchain?

In the context of blockchain, particularly within permissioned networks like those facilitated by IBM Blockchain, the lifecycle of a transaction involves several key processes to ensure security, accuracy, and consensus among network participants.

One critical aspect is that the endorsing peer simulates a transaction. This simulation occurs when the client sends a transaction proposal to one or more peers within the blockchain network. The endorsing peers then execute the transaction in a simulated environment, which ensures that the proposed transaction would yield the expected outcome if it were to be committed to the ledger. This simulation provides valuable feedback to the client and helps to verify that the transaction adheres to the chaincode rules and reflects the current state of the ledger.

This characteristic emphasizes the importance of verification in the transaction lifecycle, as it mitigates the risk of invalid transactions being processed. By requiring that the transaction is simulated by endorsing peers, the network can maintain its integrity and reliability.

In contrast, other scenarios, such as endorsing from random peers or not requiring endorsement at all, do not accurately reflect the structured process needed for maintaining security in a blockchain environment. Similarly, processing transactions without broadcasting would undermine the transparency and consensus required for a decentralized system. Thus, the endorsement process, specifically the simulation performed by endorsing
