The battle rages on within the Bitcoin community on how to move forward with potential hard fork changes designed to accommodate larger block sizes. Jeff Garzik’s BIP 100 proposal has taken the mining industry by storm, gathering a majority of support of those currently voting. Meanwhile, Bitcoin corporate leaders have formed a united front around the proposal by Mike Hearn and Gavin Andresen called BIP 101.

Which side are you on?

On Tuesday, August 24, the leaders of many of the largest Bitcoin companies in the world signed off on BIP 101 as their revision of choice. They crafted a manifesto declaring a solid vote of confidence of BIP 101. For details on how BIP 101 works, click here to see the details on GitHub, posted by Gavin Andresen.

The Chief Executive Officers include Stephen Pair of BitPay, Peter Smith of, Jeremy Allaire and Sean Neville of Circle, Sam Cole of KNCMiner, John McDonnell of, Charles Cascarilla of itBit, Wences Caseres of Xapo, and Mike Belshe of BitGo. An excerpt reads:

We support the implementation of BIP101. We have found Gavins arguments on both the need for larger blocks and the feasibility of their implementation, while safeguarding Bitcoins decentralization, to be convincing. Our companies will be ready for larger blocks by December 2015 and we will run code that supports this.

As our community grows, it is essential, now more than ever, that we seek strong consensus to ensure network reliability. We pledge to support BIP101 in our software and systems by December 2015, and we encourage others to join us.

This high level of corporate support has not been shared by the voting mining community. In fact, quite the opposite, as those who are voting over the last month have flocked towards Jeff Garzik’s BIP 100 proposal, as we have reported here.

Bitcoin Block Size Debate Reaches The Alex Jones Show

Other community leaders have spoken out on this issue. Julia Tourianski of was the guest host on the Alex Jones Show on Friday and responded to a caller’s question about this issue directly.

“Bitcoin XT is a terrible idea, and I would take the other core engineers and developers much more seriously,” Tourianski replied on air. “(They) are organizing an event in Montreal (“Scaling Bitcoin”) in September to have an open dialogue about the changes, and how we can implement them incrementally, and what is the best way of going about it.”
