Many people in the cryptocurrency community know that some early miners have tapped a lot of bitcoin. For example, Dave Kleiman and Crab Wright have been reported to have jointly tapped 1.1 million BTCs, and many even suspect Dave Kleiman. It is the real Nakamoto.
This week, RSK Labs chief scientist Sergio Demián Lerner published an analysis of early mining blocks on the Bitcoin network. According to strong evidence, an early miner handled 22,000 blocks. To better help the encryption community understand the mining situation during the birth of the Bitcoin protocol, Sergio Demián Lerner also launched a new website called "Satoshi Blocks."

The evidence shows that he dug 1.8 million BTC
Recently, independent researcher and cryptographer Sergio Demián Lerner published an in-depth study of early bitcoin mining. In fact, as early as April 17, 2013, he had released his first research report, and found that the vast majority of BTCs were mined by a miner. In addition, Sergio Demián Lerner's blockchain analysis also tracks the "extranonce" domain from the Coinbase transaction itself "coinbase field stemming" and generates a corresponding set of analytical data. At the time, Sergio Demián Lerner estimated that the miner had already excavated 1,814,400 BTC, but 63% of the bitcoins that had been mined (that is, about 1.1 million bitcoins) had never been used since the day of excavation.
Six years later, in 2019, Sergio Demián Lerner released a more rigorous study that provided stronger arguments to support his previous judgments. In this paper entitled "The Return of the Deniers and the Revenge of Patoshi", he first explores his own original research and the reasons for his previous conclusions. Sergio Demián Lerner analyzed in detail how he found reliable information in the "extranonce" domain and found it in "vulnerabilities" through some non-privacy protection.
Sergio Demián Lerner identified an independent miner who dug up about 1.1 million bitcoins during 2009-2010, after which Sergio Demián Lerner also analyzed a “Patoshi mining mode”, as shown by the blue line below. The mining mode (blue line) of this "Patoshi" miner is considered to be completely different from other miners (green lines).
Create an early model of the mine
Sergio Demián Lerner also carefully analyzed the "Patoshi" independent miner in the paper. He felt that he now knows what the unique mining method of "Patoshi" is, because this method is probably the "mine pool". The predecessor, and some people gradually accepted the existence of this mining method and began to use it after several years of "Patoshi". Sergio Demián Lerner's point of view is not unfounded. He cited many reasons and explained various factors, including:
99% of the blocks excavated by “Patoshi” are unspent;
Each "Patoshi" dug block is "associated" to a block under this mining mode set and is not associated with any other block;
After a period of time, the mining mode "Patoshi" was suddenly interrupted;
A few years later, the "mine pool" was born;
The purpose of creating a mining pool is to reduce the problem of lower block rewards obtained by individual miners when verifying transactions. However, in 2009, a miner could easily “get it”.
At the end of 2013, Sergio Demián Lerner made it very clear that this mining model was real and used a completely different mining method. According to his latest research, all the blocks mined by the "Patoshi" miner pass through a depleted "nonce" range, which is used to process blocks in a specific range.
Next, from 2014 to the beginning of 2019, Sergio Demián Lerner found that the mining model “Patoshi” did not change much. According to recent studies, “Patoshi” only produced about 700,000 BTC. However, Sergio Demián Lerner “provided a great possibility” that a miner extracted all BTCs after mining in the “Patoshi” mining mode, amounting to more than 1 million. Sergio Demián Lerner made this judgment based on the computer clock, because even in the early stages of Bitcoin, the miner used the local clock to add time stamps to the block after completing the block processing.
According to Sergio Demián Lerner, the miner "Patoshi" had 10 days to suspend mining. He also revealed that the miner also donated about 550 BTC to others in the form of donations. Sergio Demián Lerner wrote:
“If you've studied the Bitcoin protocol, you know that timestamps don't necessarily increase in one direction, from bitcoin source code version 0.1.0 to the latest version of Bitcoin Core with internal miners (before the mine was created). ""
Clock and time stamp
According to some recent evidence provided by Sergio Demián Lerner, he is very convinced that the “Patoshi” miner extracted nearly 1.1 million BTC (more than 1 million BTC when Sergio Demián Lerner studied many years ago). For example, Sergio Demián Lerner believes that computer clocks can be asynchronous to each other, timestamps are not continuously updated during mining, and block timestamps can be adjusted by Bitcoin software to match the two sides of the transaction (ie Peer) connected to a node. Intermediate time. For these reasons, Sergio Demián Lerner points out that the same computer can almost never change (or reverse) its own timestamp, and the increment between inverted block timestamps also indirectly monitors the parent block (parent) Block) The miner's hash value.
The following image is a timestamp inversion case studied by Sergio Demián Lerner:
Sergio Demián Lerner wrote in his research paper:
There is no time between the “Patoshi” blocks, there is no time, and the miner’s mining blocks account for 43% of the top 50,000 blocks in Bitcoin. I am willing to consider other explanations, but for me this means There is only one situation: there is only one PC clock, and the time of this clock is marked in the block dug by “Patoshi”, which is mined by one person.
As the chief scientist of RSK Labs, Sergio Demián Lerner finally opened a brain. He thought that a single software that could control how a block template was created could only be an independent miner, and the miner would probably be Nakamoto.
