Sergio Demian Lerner, a computer security researcher has revealed that Bitcoin’s creator used a single computer to mine an estimated 1 million bitcoin minted in the early days.
Lerner’s latest research “The Patoshi Mining Machine” looks into whether or not the Patoshi pattern (Satoshi’s mining) was done by multiple computers or a single PC. Lerner simulated Satoshi’s mining experience by “mining a large part of Patoshi nonce space scanning sequentially in the range.”
The Lerner’s research noticed a tendency while re-mining the old Satoshi bocks which reduces the nonce value.
“It turned out that re-mining reveals a strong tendency of the Patoshi mining algorithm to choose higher nonces when scanning the inner nonce. This tendency suggests the nonce was being decremented, which is the opposite that the Satoshi client version 0.1 does,” ” Lerner discovered.
The finding leads Lerner to believe that Satoshi didn’t leverage 50 computers to mine the Patoshi blocks and it’s very likely the inventor utilized a single machine back then.
This contradicts a theory that Patoshi deployed the first mining farm of 50 independent computers (or any other highly decoupled system) and supports the theory that Patoshi was simply multi-threading in a high-end CPU.
Sergio Demian Lerner is well known for publishing one of the first estimates backed by technical data in 2013 concerning Satoshi Nakamoto’s alleged stash of bitcoin.
