In keeping with new research, it’s possible that Satoshi Nakamoto carried out a 51% mining assault on the community in its first 12 months of existence.
An in-depth information overview of 2009 blocks mined by Patoshi — a nickname for a frequent miner who embedded a non-standard use of ExtraNonce inside coinbase transaction information — suggests it’s very possible that they used hash energy to reorganize Bitcoin’s blockchain.
In different phrases, as Bitcoin historian Pete Rizzo defined, when Patoshi sometimes took breaks from mining, their pc restart was “so powerful that the miner [Patoshi] simply overwrote blocks found by other miners in their [Patoshi’s] absence.”
A 51% assault is strictly what it seems like — attaining 51% management of the Bitcoin community, measured by hash fee, to overpower different miners and regain management of recent transaction confirmations.
Patoshi — a portmanteau of ‘pattern’ and ‘Satoshi’ — was mining in 2009 when it was extraordinarily possible that Satoshi Nakamoto owned the one pc related to the community. This has led many individuals to conclude that Patoshi and Satoshi have been the identical particular person.
Extra detailed analysis by Depraved Sensible Bitcoin this week that builds on Lerner’s research additionally means that Patoshi in all probability carried out a 51% mining assault throughout 2009.
As a result of Bitcoin has at all times been a proof-of-work (PoW) blockchain, whichever miner works the toughest earns the best to mint coinbase rewards and add transactions to the ledger. Throughout Patoshi’s breaks from mining, no different miner accomplished sufficient hashing work to forestall them from returning and taking again management.
Satoshi’s ‘51% attack’ was an assault in title solely
It is very important observe that bitcoins had no worth in 2009, so the assault was a stress take a look at and never for monetary achieve.
Though the actions of Patoshi, who was possible Satoshi, meet the definition of a ‘51% attack,’ that time period is a poor characterization of what occurred. Once more, as a result of bitcoins had no monetary worth on the time, the conduct was merely for research functions or inadvertent.
Certainly, Satoshi had one of many solely computer systems related to the Bitcoin community in early 2009 throughout these blockchain reorgs. Amongst different research pursuits, Satoshi additionally seemingly examined the Bitcoin community’s Issue Adjustment by various hash energy contributions in 2010.
All of those actions occurred whereas bitcoins have been free. To be clear, miners may earn coinbase rewards for mere pennies value of electrical energy, and Martti Malmi gave away 30,000 bitcoins through a free web site ‘faucet’ all through 2010.

So whereas it is perhaps true that Satoshi carried out a 51% assault on Bitcoin, it will have yielded no fast monetary achieve. To this present day, Satoshi has bought practically zero of the 1.1 million cash mined in the course of the first two years of the foreign money’s existence.
As Depraved Sensible Bitcoin summarized to Protos, “Whereas Satoshi shepherded Bitcoin by its first 12 months of existence, it seems like he might have carried out some real-world stress checks such because the reorgs in Might 2009 and purposefully orchestrated downward problem adjustment in Might 2010.
“None of these acts seemed malicious in nature but were rather to check the integrity and robustness of the system he had built.”
