Why is this taking so long to resolve?
It actually was resolved pretty fast. (6 blocks ~ 1h)
There was a second incident on July 5th, with a 3-block orphan branch. There are still v2 miners out there, and the v3 miners are still accepting recent block hashes from them, and mining new blocks on top of them before they have time to validate (or even see) those parent. The fork was blotched.
Could you explain this further, I thought bitcoin 10 or above would block v2 blocks from being accepted. So what your saying those blocks are still finding a way on this side of the forked blockchain. Like f2pool i know they fucked up and did something like that but i thought it was isolated event which was fixed. Would this bog bitcoin core down it's been stalling a lot from what miners are saying. I think bitcoin core should be more efficient at blocking those left behind without the extra resources (cpu and ram) to effectively block them.
Please criticize my recollection of what is happening that's the only way i will learn about this in more depth.
