It was the life of a hacker for Dr. Adam Back, CEO and co-founder of Blockstream. One of the few people cited in the Bitcoin white paper, the hacking highlights of Back’s life are brought to life in the latest animated Crypto story from the Cointelegraph video team.

During a game of Jenga in a park, Back told Cointelegraph that he’s always had a “kind of security mindset.” Since his days as a student, he has been tinkering with door codes, pin pads and locks, code testing and getting access to places he “wasn’t supposed to be able to”.

Back talks about creating Hash Cash, one of the early attempts at digital money. It uses the “birthday collision” as code for hash functions, demonstrating its willingness to break down complex functions into understandable language:

“If you have a room full of people at a party or something, there’s a question of how many people have to be in the room before there’s a 50/50 chance of two people having the same birthday.”
He explains that while people expect the result to be related to the number 365 – given the number of days there are in a year, the reality is much less. This line of reasoning, combined with an understanding of spam, led to Back coding for Hash Cash.

Bitcoin stands on the shoulders of Hash Cash, but Bitcoin caught on because Bitcoin has a high level of decentralization, which is vital to the success of the cryptocurrency. Back adds that Bitcoin is also “understood on many different levels, right?”

“You can understand it from the user level or from the economic level. It’s surprisingly complex to fully appreciate all of that, including game theory and things like that.”
The cartoonish interview ended by noting Blockstream’s decision to take Bitcoin into space and asserting that there will be “more Bitcoin,” from one of the OG groups in the Bitcoin economy.
