Performance impact as number of Nodes in Blockchain increase

Question

Hi

We are trying to implement a private blockchain starting with 10 nodes. Going forward we want to expand it to hundreds of nodes.

In our blockchain we want to credit points to user account based on certain action. This has to happen in near real time hence we have performance as one of the most important criteria for selecting blockchain platform.

I understand multichain based blockchain can do around 1000 TPS.

However as we know every commited block in blockchain has to be replicated to all nodes in blockchain network. So if the number of nodes in network increase it would add more latency due to increased number of nodes.

Is this understanding correct? If yes how TPS is affected with increased number of nodes.

Answer 1

The supported rate of transactions per second is barely affected by the number of nodes, since each node independently processes all transactions. You will see more latency as transactions and blocks have to make more hops to propagate to the entire network, but looking at the performance of the bitcoin network, it's still a matter of one or two seconds in the worst case.
