Can i also Burn with 1.2.5 or i need the 1.2.5.1?
When i will Burn 10k BLK
then i must:
burn 10000 "Public key"
Then i must update on 1.2.5.2 and i can stake with my old wallet dat BLK "old"?
Yes. Also you can use 1.2.5 with account generated on site:
https://blacknet.ninja/generator.htmlcan i enter new blacknetkeypair command! Will the new mnemonic key be valid for the previous public key, for which I did not initially save the mnemonic key

Creating a new mnemonic will make a new key. it won't be linked to a previous key pair.
If you didn't save the mnemonic for the public key you used when burning blk, I think the blackcoin and the blacknet tokens are both lost to the void forever.
I think we can replace the key, if he proves ownership of burned BLK and there are no objections.
OK, so THX then i will done follow steps:
- start old wallet 1.2.5
- Generate a new key:
https://blacknet.ninja/generator.html and write down the "account, "public key" and "Mnemonic"
- Start the debug window or CLI to execute following commands.
- For example with 10k old BLK and these public key: 28728a408f080aec48be9a0e07dd509f7be98f9cb8ce94c7630702154af7cced
- burn 10000 28728a408f080aec48be9a0e07dd509f7be98f9cb8ce94c7630702154af7cced
- So i can wait for the new Blacknet Wallet with my "account, "public key" and "Mnemonic"
- Then i close the BlackCoin Wallet and update at 1.2.5.2 and can stake at the BLK chain and the remaining BLK.
- After the release of the new Blacknet i can restore my new Coins!
I think this is correct?
Correct.
You can post it here or on gitlab.
