There is a second update (after
https://bt.irlbtc.com/view/4070404.msg38754844#msg38754844) that seems mandatory because otherwise you'll be mining on another chain ... The second update is available on the website.
Yesterday, I updated according to the post. Today, I updated with the second update and all seemed fine, however when I checked one of the last blocks (getblock <blockid>) it didn't have the same hash as the one displayed in the block explorer for that block. So I removed all the files in .komodo/VRSC (I'm on Linux) apart from wallet.dat and started Agama, I then had the "RPC connection" error, so I restarted Agama and it was fine, however, the last block I minded is no longer visible. Either I mined it on another chain or I'm missing something. That block was mined at 8:xx AM UTC, does this make sense?
Almost certainly that block was mined on a fork that was orphaned. The RPC issue was our nodes getting blocked yesterday, which led to a number of problems. We have addressed that issue, but we are still investigating sync problems right now. If you got up to date on the network and don't see the block, 99.9% (or more) chance that it was just mined on an orphaned chain.
Are you saying that it was also mined by someone else, and that's why it was orphaned, or something else?
Was it normal that I was on another chain despite having installed the (first) update before the deadline? It seems the second update is mandatory to mine on the right/strongest chain, if so, can you please make a(n official) post about it here?
Glad to hear that you are working on fixing issues, not that I doubted it in the first place
. Keep up the good work.
Thank you!
When a fork occurs, or even when multiple people find the same block virtually instantly, only one gets accepted. When there are small forks, same thing. When there are larger forks, often the hashpower on the main chain far exceeds the other(s), and sometimes people can mine many, many blocks because there is almost no one on the chain and they lost the main one. I'm not saying that these are exactly the things that happened, just generally what can. Yesterday, as a small coin with fewer stable nodes than most, we got all of our stable nodes blocked, and many people weren't connecting properly. With the different versions coincident, we ended up with at least one large group of miners on one chain forked from the main chain. The people in our community discord helped us connect to them, and they upgraded and the fork resolved, but until people upgrade, possibly clear out their chain folder data while saving their wallet (instructions on our discord (
https://discord.gg/VRKMP2S) they may have trouble getting back to the main chain.
We learned a number of things, including that we need more fixed ip nodes in different DCs, and a community member in Europe provided nodes for everyone as we were getting it resolved. I'm spending most of today making sure all is good, and once that is done, back to forward progress
