# hello world By [zzzzjesus.eth](https://paragraph.com/@zzzzjesus) · 2022-04-27 --- Satoshi Nakamoto is the name used by the presumed pseudonymous\[1\]\[2\]\[3\]\[4\] person or persons who developed bitcoin, authored the bitcoin white paper, and created and deployed bitcoin's original reference implementation.\[5\] As part of the implementation, Nakamoto also devised the first blockchain database.\[6\] Nakamoto was active in the development of bitcoin up until December 2010.\[7\] Many people have or have been claimed to be Nakamoto.

On 31 October, Nakamoto published a white paper on the cryptography mailing list at [metzdowd.com](http://metzdowd.com) describing a digital cryptocurrency, titled "Bitcoin: A Peer-to-Peer Electronic Cash System".\[10\]\[11\]\[12\] On 9 January 2009, Nakamoto released version 0.1 of the bitcoin software on SourceForge, and launched the network by defining the genesis block of bitcoin (block number 0), which had a reward of 50 bitcoins.\[13\]\[14\]\[15\]\[16\] Embedded in the coinbase transaction of this block is the text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks",\[17\] citing a headline in the UK newspaper The Times published on that date.\[18\] This note has been interpreted as both a timestamp and a derisive comment on the alleged instability caused by fractional-reserve banking.\[19\]: 18 Nakamoto continued to collaborate with other developers on the bitcoin software until mid-2010, making all modifications to the source code himself. He then gave control of the source code repository and network alert key to Gavin Andresen,\[20\] transferred several related domains to various prominent members of the bitcoin community, and stopped his recognized involvement in the project.\[citation needed\] Nakamoto owns between 750,000 and 1,100,000 bitcoin. As of November 2021, that puts his net worth at up to 73 billion US dollars, which would make him the 15th-richest person in the world.\[21\] --- *Originally published on [zzzzjesus.eth](https://paragraph.com/@zzzzjesus/hello-world-6)*
