How it all started.
Various people from across the world have been working tirelessly on blockchain technology and crypto currencies since the 80/90’s and there have been multiple attempts to solve the complex issues surrounding cryptocurrency, by arguably some of the most brilliant minds in this space.
One of the first attempts to create a system close to Bitcoin was by David Chaum who created the first known proposal for a blockchain protocol. In 1997 Dr. Adam Back created Hashcash and in the following year Wei Dai published a proposal for B-Money. Both Hashcash and B-Money are referenced in the Bitcoin whitepaper and the work of these bright minds became the building blocks of the Bitcoin Protocol we know today.
The receiver of the first bitcoin transaction was cypherpunk Hal Finney, who had created the first reusable proof of work system (RPoW) in 2004.

David Lee Chaum is an American computer scientist and cryptographer.
Outstanding achievements
He is known as a pioneer in cryptography and privacy-preserving technologies, and widely recognized as the inventor of digital cash.
His 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups” is the first known proposal for a blockchain protocol. Complete with the code to implement the protocol, Chaum's dissertation proposed all but one element of the blockchain later detailed in the Bitcoin whitepaper.

Wei Dai is a computer engineer known for contributions to cryptography and cryptocurrencies.
Outstanding achievements
Wei developed the Crypto++ cryptographic library and created the b-money cryptocurrency system in 1998. He also co-proposed the VMAC message authentication algorithm.
Dai was one of the first people contacted by Satoshi when he was developing Bitcoin in 2008 and the b-money paper was referenced in the subsequent Bitcoin whitepaper.
CV stuff
Satoshi Nakamoto is believed to be a pseudonym name used by the person or persons who developed and launched Bitcoin anonymously.
Outstanding achievements
Notable events linked to Satoshi are the registration of the domain name "bitcoin.org" in August 2008. This was followed by the posting of a link to a paper authored by Satoshi Nakamoto entitled Bitcoin: A Peer-to-Peer Electronic Cash System to a cryptography mailing list in October 2008.
On 3 January 2009, the Bitcoin network was created when Nakamoto mined the first block of the chain, known as the Genesis Block.
Famously embedded in the first block was the text "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”. This note references a headline published by The Times and has been interpreted as both a timestamp and a comment on the instability caused by our current financial system.
Satoshi Nakamoto holds approximately one million BTC representing a value of US$ 8,820,000,000 at the time of writing (8.82 Billion) which still remains untouched.

Hal Finney was a highly regarded computer scientist and cypherpunk.
Outstanding achievements
Hal Finney’s contributions were pivotal to Bitcoin. In 2004, Finney created the first reusable proof of work system years before Bitcoin. He was an early Bitcoin contributor and received the first Bitcoin transaction from its creator Satoshi Nakamoto.
In August 2014, Finney sadly passed away due to complications arising from motor neurone disease, and is cryopreserved.
