Satoshi Nakamoto is the pseudonymous creator of Bitcoin, the first decentralized cryptocurrency. In 2008, Nakamoto published a whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System," which outlined the concept and technical design of Bitcoin, a digital currency that operates without a central authority.

In 2009, Nakamoto released the first version of the Bitcoin software and launched the network by mining the genesis block (the first block on the blockchain). Nakamoto was active in Bitcoin's development for about two years before gradually reducing involvement and eventually disappearing from public view in 2011.

To this day, the true identity of Satoshi Nakamoto remains a mystery. Several individuals have been speculated to be Nakamoto, but none have been definitively proven to be the creator of Bitcoin. Nakamoto is estimated to hold a large amount of Bitcoin (around 1 million BTC), which has remained unspent.
