I got 5 stakes yesterday 3 of my minted BTC2 was Orphans, I hope the Dev team will fix the nodes, I only got 3peers even I deleted the peers.dat file on the roaming directory..
As I've said on my previous post, I saw the unusual activity, When I get some minted block I figure out that my orphan minted coin on the other day became valid minted coin.. Is this normal? Well if this thing will always happen, it is favorable for us.
Orphans happen on proof of stake more often than in proof of work but it doesn't matter. As soon as your wallet realizes it created an orphan it will resume staking with that same amount as if it never happened. Any transactions that went into an orphan block just go back into the memory pool.
And the smaller the block interval, the more orphans. (if 1 block created per minute like in Bitcoin 2, then orphans are more likely than if just 1 block created per 10 minutes like in Bitcoin).
We could hide the orphans from ever showing on your transactions list like some other wallets do, but then you wouldn't know that you came close to creating a valid block and you wouldn't know that there's something that you might possibly be able to do to get at least a little less orphans. It is best to just not care about the orphans once you've already tried the ways we mentioned earlier that help getting less of them. Also, showing the orphans is a good indicator because if some day you're not getting any orphans and are creating more blocks than normal, in such a case you could be forked and would need to take action to unfork yourself. So having those orphan blocks showing up is helpful.
EDIT: As far as some orphaned block becoming valid a day or more later: Technically it doesn't. That block is a new block that you minted that just happens to have the same staking transaction. (Uses the same UTXO to stake.) Your wallet displays it like that because the orphan block's transaction is still in your wallet. If you zap wallet transactions (Tools - wallet repair - Recover transactions), you would see the correct time stamp (this is optional). Before zapping transactions it's always a good idea to make another backup of the wallet.dat. This is a display-only bug that has no actual negative effects apart from the confusing way that the transaction gets displayed in your wallet's transaction history. Added to the programmers' todo list to fix it.
