Amaclin

• Bitcointalk.org user “amaclin,”, has claimed to be behind the maleability attacks on the Bitcoin network in october 2015. Amaclin, who is probably Russian (or at least speaks Russian), announced his involvement in the malleability attack shortly after it was first noticed on October 1.
• Amaclin says he has carried out the attack, essentially, out of boredom. Additionally, amaclin argues that Bitcoin is fundamentally broken. He specifically points out that the incentive structures of Bitcoin’s development process do not align well, as users are not incentivized to reward developers for their work building and maintaining Bitcoin. By attacking the network, amaclin believes he is revealing that only a small number of developers can fix the issue, while most Bitcoin users expect them to do so for free. That is an unsustainable proposition, amaclin says.
• Amaclin claims that he is not attacking the network in order to gain financially in any way. He also denies attacking any specific business in order to defraud them or otherwise. He has, however, posted two donation addresses in his forum signature: One is labeled a vote for the attack, while the other is labeled a vote against. At the time of writing, both addresses have had one transaction sent to them, adding up to 300 bits, worth less than 10 cents in total.
