According to the developers, zero dollars were lost due to unsecured mining. Although at the same time, other sources are claiming a loss of $316,000.
Dogechain halted transactions this weekend after developers discovered a critical error in the project's bridge contracts. It happened on Sept. 10, and developers had to stop the ability to create new blocks of the blockchain (which is how transactions are made).
The error could have allowed attackers to freely mine wrapped DOGE (wDOGE) on the bridge network. In fact, it is like HESOYAM, only in real life :D.
The project said that its network is currently running on the Proof-of-Authority (PoA) consensus mechanism allowed the team to cancel "unwarranted wDOGE mining." It added that the network will remain on PoA until the team is fully prepared to switch to Proof-of-State (PoS) consensus.
On the other hand, the project team states that they found the bug themselves, & it's not a matter of exploiting or hacking. Well, and as already mentioned, not a single Dogecoin was stolen.
Although, at the same time, independent crypto researcher Crumbs suggests that someone has already minted 9.7 million DOGE (that's about half a million dollars). And then the perpetrator converted $316,000 of it & took it out to Binance.
Although, again, nothing is clear to the end: they put some wallet on the blacklist of the platform, or someone later tried to mint DOGE with a bug, but it seems that the minting was canceled at the end.
If u take all the facts, then most probably somebody really tried to steal tokens by exploiting the vulnerability or earning some money with them. Still, the fact that somebody managed to get it all out is unlikely...
In the end, we'd also like to make it clear. Officially, the Dogechain and Dogecoin (DOGE) projects r not connected in any way. Also, the mentioned bug has no relation to the recent data leak that affected Shiba Inu.
