i have a coin for my own interests. With this i will learn how works all.

So i have install the daemon on a vps All works fine.

Mining works. And the first 300 blocks i have created.

Now i will back to block 100 or 200. But i don't know how?

It is only one node (1vps) and 1 windows wallet.

Is it enough to delete all files and directorys except the coin.conf and wallet.dat on the vps and in windows?

Or how i can back to block 200?

Many thanks Mark

invalidateblock "blockhash"

Permanently marks a block as invalid, as if it violated a consensus rule.


  1. "blockhash" (string, required) the hash of the block to mark as invalid

Don't delete the blocks manually, you'll harm the database.

  • Thanks MCCCS for your reply. Understand I correct this works for me when i input the hash from block 201? Then I'm at block 200? – Mark Feb 9 at 21:05
  • Yes, that's how it works. – MCCCS Feb 10 at 6:43
  • OK, thanks. And when I setup 2 vps then I must insert this in all XXX-cli or only by one? And restart number 2? – Mark Feb 10 at 18:55
  • You should do that for both. – MCCCS Feb 11 at 12:40
