Probably Adam Back for several reasons. He invented Hashcash which is used in the bitcoin mining process.

Back was the second person Satoshi reached out to with the earliest draft of the Bitcoin whitepaper, still he acted
like a noob on the forums to throw people of.

Adam Back was a pioneer in the field of cryptography, and his contributions to the Cypherpunk movement were very
important. He was an active participant in the group's debates, and his Hashcash function inspired the development
of other algorithms and programmes by his fellow Cypherpunks, such as Hal Finney's RPoW and Bitcoin.

Not only does Back have a Ph.D. in computer science and a history of studying cryptography in academia, but he has
also built his whole career on ideas that are central to Bitcoin.  He is the CEO of Blockstream, which he co-founded
in 2014 and I feel it´s his way to get back into control of bitcoin.

He also writes in the same way as Satoshi.
