What aspect of a blockchain platform is enhanced by increasing the pool of endorsing peers?

Increasing the pool of endorsing peers enhances the transaction per second (TPS) rates in a blockchain network. This improvement is driven by the fact that with more endorsing peers available, the network can process and validate transactions more efficiently. Each transaction typically requires endorsement from a certain number of peers to ensure its authenticity and compliance with the network's rules. When the number of endorsing peers is higher, the workload is distributed across more nodes, allowing for parallel processing of transactions.

This leads to reduced bottlenecks and speeds up the overall transaction validation process, thereby increasing the TPS rates. As a result, the network becomes more capable of handling a higher volume of transactions in a given timeframe, which is crucial for scalability and performance in blockchain applications.
