Mike Hearn, after stopping work on bitcoin, joined the banking consortium R3. He expressed his opinion on a variety of issues, including Bitcoin Cash and the debate about the size of the block, which eventually led to the fact that last summer the ways of the developers diverged. This is reported by Coindesk.

It is worth noting, in particular, the words of Hearn about their own attempts to reform the protocol of bitcoin in 2015 and early 2016, which became harbingers of the fork. Together with Gavin Andersen, chief researcher at the Bitcoin Foundation, Hearn introduced a code to increase the block size, suggesting a hard fork, but his project did not go through the voting stage. Later, Hearn left the Bitcoin Core development team, writing that the bitcoin project "failed" due to problems with the community.

However, now Hearn believes that Bitcoin Cash inherited a lot of problems of the original project.

[Bitcoin cash] strongly resembles the bitcoin community of 2014. This is not good.

Hearn also said that Bitcoin Cash, like bitcoin in 2014, is lacks "formalized governance" and communicates mainly through Reddit, where users, he said, can censor unpopular opinions.

Thus, he advised Bitcoin Cash users to "find a replacement" for a forum where the power of the moderator will be limited, and the community's views on future upgrades can be evaluated correctly. In particular, he expressed "alarm" over the fact that Bitcoin Cash plans to conduct hard fork in its срфшт, "with no attempt to measure support"

Nevertheless, he called the Bitcoin Cash community "brave."

"Liberate yourselves from just proceeding along the path Satoshi imagined and be willing to think radical, even heretical thoughts," he concluded.
