This is about WEB3J (on Java)

Just be careful of setting from zero to latest filter range. I'm doing this on my private chain.

The OP asked for help on JAVA WEB3J. Not Javascript.

Very well. I'll check all these details again having this in mind. Many thanks.

Wait a minute! time to reflection ... On second thought I'm not sure if I restarted the entire network... Are you telling me that if this value starts high, a block will never be produced faster than that?

I'll reward you anyway because you gave attention to this question. But please tell me why it is allowed to put a high value in blockperiodseconds if the node start to cry when a block is produced faster.

Sorry, but it seems like you didn't understand my question. My network is running indeed, but every time I change anything in genesis file I simply reset it all to begin again. So my question is not about how to CONFIGURE this value. It was working as expected anyway. My question is about WHY the nodes are complaining when a block is produced faster then that value. I'm afraid of that. Ex. If I configure a value of 10 like you suggest and a node produces a block in 3 it will complain (witha warning or error I can't remember )

@OZ_ done! It is a basic genesis from tutorial (same wallets too) with few changes

And what if there is no contract call involved? Like a native (ETH) transfer?

I think you should use it. If there is no data then it will be closed.
