Gavin Andresen Publishes BIP 101

- Market Structure

Gavin Andresen published BIP 101 on June 22 2015 calling for an increase in Bitcoin's maximum block size. The proposal aimed to activate eight MB blocks once 75 percent of 1000 mined blocks met the threshold after the start of 2016. It doubled the block size limit and scheduled further doublings every two years. The post ignited the first major block size war on Bitcoin forums and mailing lists.
