The Chinese mining company Bitmain is no longer a sponsor of bitcoin development.
According to Bitcoin Core technical administrator Jonas schnelli, the company refused to further cooperate with Him. In addition, she broke off relations with bitcoin developer Joao Barbosa, according to schnelli.
According to data collected by the BitMEX crypto derivatives exchange, which itself actively allocates grants for the development of bitcoin, Bitmain sponsored only two of these developers.
Schnelli writes that he received Bitmain support for three years. The developer thanked the company for their help, "despite their differences," and said that he was open to receiving sponsorship payments. According to the developer's github page, it currently has 41 sponsors; many in the comments also expressed their willingness to support it.
Unlike some other developers, schnelli is working on the development of bitcoin on a full-time basis. He was introduced to cryptocurrency in 2011 and first took part in writing the code for it in 2013, since then contributing about 30,000 lines.
According to some opinions, the refusal of Bitmain from further cooperation with schnelli is due to the fact that The company is not interested in supporting developers who focus on second-level solutions, one of the consequences of which is a decrease in the income of miners. Schnelli himself States that he is currently engaged in a proposal to improve bitcoin BIP324-a message transport Protocol with additional features for protecting network participants.
