I have decided to modify the proposal to instead begin the increase steps at the current 1000000 byte limit. The increases and the time spam of each increase will remain the same, just that the increase begins from 1000000 bytes instead of 300000 bytes. Furthermore, instead of a fixed schedule from a fixed point in time, the increases will instead be calculated off of the MTP of the activation block (the first block to be in the active state for this fork). While this proposal shares many of the same issues with the one it modifies, I hope that it will be slightly less controversial and can allow us to move forward with scaling Bitcoin. The full text of the proposal can be found at https://github.com/achow101/bips/blob/bip-blksize/bip-blksize.mediawiki. My implementation of it is available at https://github.com/achow101/bitcoin/tree/bip-blksize Andrew
