Here’s the situation:
I noticed unusual delays and failed transactions on a certain blockchain network, even though the network wasn’t showing signs of congestion.
You are in this board: Bitcoin Forum > Bitcoin > Bitcoin Technical Support. This is the place to ask for Bitcoin technical support not support for a "certain blockchain network".
I’m curious if others in the community have encountered something similar. Could this be related to network-level latency, mempool issues, or something else entirely?
Nobody can help you with a general inquiry like this. You need to specify what network and examples of this happening.
Before some sig. campaign spammer responds, it is very likely this is an AI request anyway. So ignore it.
