From the various threads discussing your proposal, it seemed that many would favor it if it increased over 1 MB sooner or if it never even decreased in the first place. > Your version doesn't address the current block size=20 > issues (ie, the blocks being too large).=20 Many users are of the opposite opinion, that the block size is too small. I understand that the decrease is to allow the blockchain size to grow more slowly thereby allowing users to be more likely to run full nodes. Unfortunately, I think that we are way past the point of no return on that. The blockchain is already 100+ GB. Decreasing the block size is not going to make that any smaller and is not going to make it any less painful to run a full node. Given that in order to start up a new full node will still require downloading at least 100 GB of data, I don't think that decreasing the block size will better facilitate full node creation. Furthermore, the current trend with ISPs (at least in the US) is implementing data and bandwidth caps so users are still unlikely to start up new full nodes regardless of any changes that we can currently do. > So you've retained the only certain- > DOA parts of my proposal, and removed the most useful part...

Yes, I know deployment needs to be fixed. I was more proposing this for comment on the modified block size schedule. I just kept the deployment as it was originally. However, we could use a modified version of BIP 9 by using one of the top three bits and a longer locked-in period as a grace period for all users to upgrade. > > On Sunday, February 05, 2017 9:50:26 PM Andrew C via bitcoin-dev wrote:= >> Hello all, >> >> Many people have expressed discontent with Luke-jr's proposed block si= ze >> BIP, in particular with the decrease in size that would occur if it we= re >> to be activated prior to 2024. >> >> I have decided to modify the proposal to instead begin the increase >> steps at the current 1000000 byte limit.
