Can I get a quick pointer as to what is corrupting the blockchain, is the mini-blockchain concept the problem ?
I got the issue when syncing from scratch only. When using a downloaded blockchain, the wallet worked for months.
I think i can take time from my own work tonight to try a fresh sync and observe any errors or abnormalities.
There's a possible attack that mentioned in the whitepaper when there's not enough contributing members with newly synchronizing wallets
That is a different blockchain exists in the network that claims to have higher mining effort (higher total difficulty) and the wallet tries to sync with that version of the blockchain and gets stuck at some point where it can't sync anymore and I believe that point is 7 days behind current time because that's the point where a real blockchain exists on the network
and because the "fake" blockchain seems to have higher difficulty the wallet doesn't sync with the current version of the blockchain
