My initial thought was if it were only a couple transactions I'd whitelist them to bypass verification but there are 10,000 of them so that seems a little ridiculous.
With over 10k invalid transactions we do run into the issue that there are too many transactions to just blindly whitelist, so I agree with you there.
My second thought was to bypass verification on these transactions if they were included in a block prior to the latest checkpoint, along with a newly released checkpoint however that was shot down with the idea that these transactions are still occurring fairly regularly unless we had a sort of instant fork to get around that but I don't know if that's reasonable.
I agree that it would be an issue if invalid transactions were still being generated, it would be bad.
One idea I haven't ruled out yet is to set a block such as 1,600,000 which is a ways out to transfer to block v2 and start rejecting v1's thereby forcing everyone to update to libsecp256k1 instead of openssl, the remaining issue being what to do with the blocks and transactions between now and "then".
If indeed the issue is with OpenSSL (like it seems to be) then it would be good to update to libsecp256k1, however instead of setting the hardfork at 1,600,000 set it closer to our current block.
Next idea is to just YOLO it and make an announcement then update instantly with a checkpoint to force the right side of the fork, with coordination from pool operators to ease the pain. Sort of like just ripping the band-aid off and getting it over.
Again, I'm not entirely sure the best course of action moving forward. Prior to a few days ago I knew nothing of florin so I don't know all of the details, are there many pools or solo miners? How hard would it be to pull off a YOLO update which blindly trusted any transaction prior to the new checkpoint and then began rejecting all v1 blocks from old nodes after the update?
There are currently only a few pools that mine Florincoin (with Alexandria being the main one I believe) and only a few solo miners. If we stated that there would be a hard fork at X date and had the main players update then we would be able to mitigate most of the fallout. I think that this would be the best option to move forward, though that is just one girls opinion.
It would be great to hear from the people that actually mine Florincoin or have been around with it.
