It has been little over a week since Mike Hearn and Gavin Andresen included Bitcoin Improvement Proposal 101 (BIP 101) into the alternative Bitcoin implementation Bitcoin XT. BIP 101 is designed to create a hard fork in the blockchain to allow for blocks of up to 8 megabytes, doubling every two years.
Despite a major uproar on forums, chat rooms and in the media, not to mention a significant drop in bitcoin’s exchange rate, support among miners is minimal.
