there could be compatibility between v2.8 and v2.9, because of minGasLimit, we are investigating it. but do suggest run Parity with --gas-floor-target=4712387
until our next release.
from go-musicoin.
to keep the compatibility, we may need to hardcode targetGasLimit instead of raising minGasLimit which may cause hardfork.
from go-musicoin.
This is broken in Parity as well which I use for my pool. I reported the bug here:
https://github.com/paritytech/parity-ethereum/issues/10242
I tried adjusting the minGasLimit on the musicoin.json to 4712387 but now I get this error:

Any suggestions?
from go-musicoin.
I'd just like to add that changing the chain specification mid-blockchain will almost certainly break new nodes' ability to sync from scratch - regardless of whether they're using parity or gmc.
from go-musicoin.
we may put it into next hard fork(which is also engaging other consensus change), so the gas floor will solidly protected. Or, maybe we should hardcode the flag to make sure miners execute it arbitrarily, good?
