8 Leading Bitcoin Companies Pledge Support for BIP101

BitPay,, Circle, KnCMiner, Bitnet, Xapo and BitGo have agreed to implement Gavin Andresen’s BIP 101, and to expand the current block size to 8 megabytes – doubling every two years. A statement of their support was signed by Stephen Pair, Peter Smith, Jeremy Allaire, Sean Neville, Sam Cole, John McDonnell, Wences Casares and Mike Belshe. ItBit later signed the letter as well.

They wrote:

“We support the implementation of BIP101 […] We have found Gavin’s arguments on both the need for larger blocks and the feasibility of their implementation – while safeguarding Bitcoin’s decentralization – to be convincing. BIP101 and 8MB blocks are already supported by a majority of the miners and we feel it is time for the industry to unite behind this proposal.”

The email reads:

“We're excited to announce support for purchasing bitcoin with a credit or debit card. When purchasing with a credit or debit card, you'll receive your bitcoin instantly. To start, we'll be gradually rolling out credit and debit card purchase support to users in the UK and Spain.”
