In order to avoid problems in network synchronization, all clients must be the same version
You cannot control what other people do. In NXT i still see clients of 0.x.x versions. Will NODE with different clients make their own network?
What will happen if You are using an older version of the client, and I'm new. In our case, the transaction will not be accepted and will remain in your client, because the transaction is instant and the network must be synchronized continuously.
But it must be accepted by clients with the same version as mine?
Now there are several of them , but we plan to grow the network to increase to main 100-200.
Are they hardcoded in the client?
