Connecting a node with already a multichain with the same name would corrupt datas ?

Question

Hello,

I have a node with a multichain, then I connect from another node where I had a multichain with the same name but with all different datas. Connection would merge datas, corrupting multichain ? Or simply would be built a second copy of the same multichain ?

Would be enough to delete all local data before connection ?

Another question, how I can control in which directory would be copied multichain data ?

Thanks for your help.

If you've configured a chain under a particular name on a node, and try connecting to a node on a different chain with the same name, you simply won't be able to connect to that node, because the blockchain characteristics won't match. Deleting local data would solve the problem. However you can also use the -datadir runtime parameter to use a different data directory for MultiChain when it runs. With that you'd be able to run nodes on multiple chains with the same name, on the same computer.
