To prove his claim, Wright digitally signed a message using the cryptographic keys that were associated with the creator and was backed up by experts.
Jon Matonis, co-founder of the nonprofit Bitcoin Foundation, said he believed Wright's claims after seeing the same demonstration.
"During the London proof sessions, I had the opportunity to review the relevant data along three distinct lines: cryptographic, social, and technical. Based on what I witnessed, it is my firm belief that Craig Steven Wright satisfies all three categories," Matonis wrote in a blog post on Monday.
"The social evidence, including his unique personality, early emails that I received, and early drafts of the Bitcoin white paper, points to Craig as the creator. I also received satisfactory explanations to my questions about registering the bitcoin.org domain and the various time-of-day postings to the BitcoinTalk forum. Additionally, Craig's technical working knowledge of public key cryptography, Bitcoin's addressing system, and proof-of-work consensus in a distributed peer-to-peer environment is very strong."
