In keeping with new analysis, it’s probably that Satoshi Nakamoto performed a 51% mining assault on the community in its first yr of existence.
An in-depth knowledge overview of 2009 blocks mined by Patoshi — a nickname for a frequent miner who embedded a non-standard use of ExtraNonce inside coinbase transaction knowledge — suggests it’s very probably 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 precisely what it feels like — reaching 51% management of the Bitcoin community, measured by hash price, 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 probably that Satoshi Nakamoto owned the one pc linked to the community. This has led many individuals to conclude that Patoshi and Satoshi had been the identical particular person.
Extra detailed evaluation by Depraved Good Bitcoin this week that builds on Lerner’s analysis additionally means that Patoshi in all probability performed 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 proper to mint coinbase rewards and add transactions to the ledger. Throughout Patoshi’s breaks from mining, no different miner accomplished sufficient hashing work to stop them from returning and taking again management.
Satoshi’s ‘51% attack’ was an assault in identify solely
It is very important be aware that bitcoins had no worth in 2009, so the assault was a stress check and never for monetary acquire.
Though the actions of Patoshi, who was probably 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 analysis functions or inadvertent.
Certainly, Satoshi had one of many solely computer systems linked to the Bitcoin community in early 2009 throughout these blockchain reorgs. Amongst different analysis pursuits, Satoshi additionally seemingly examined the Bitcoin community’s Problem Adjustment by various hash energy contributions in 2010.
All of those actions occurred whereas bitcoins had 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 by way of a free web site ‘faucet’ all through 2010.

So whereas it is likely to be true that Satoshi carried out a 51% assault on Bitcoin, it might have yielded no instant monetary acquire. To at the present time, Satoshi has offered practically zero of the 1.1 million cash mined throughout the first two years of the forex’s existence.
As Depraved Good Bitcoin summarized to Protos, “Whereas Satoshi shepherded Bitcoin by means of its first yr of existence, it appears like he might have performed some real-world stress exams 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.”
