Information wants to be free - Bram Cohen on BitTorrent, content, copyright & crypto (part 1)

The Crypto Conversation

This is part one of a two-part conversation with Bram Cohen. Bram is the inventor of the peer to peer BitTorrent protocol that changed the world in the early 2000s, disrupting the way we understand copyright, how we consume content, and leading to the destruction and rebirth of corporate media companies. Bram is now working on Chia Network, a cryptocurrency with the same properties as Bitcoin, but without the intensive energy footprint. Chia uses a new consensus algorithm called Proof Of Space and Time. Why you should listen: The BitTorrent protocol was a catalyst for the golden age of file-sharing in the early 2000s. Bram says it was never about being a crusader against copyright, he was simply interested in moving data from point A to point B. Listen to Bram’s memories of being a childhood programming prodigy, his early start-up failures, and his impressions of Hal Finney and Satoshi Nakamoto during the early years of Bitcoin.  Key takeaway: At its peak, BitTorrent had hundreds of millions of users and accounted for 40% of all internet traffic. At the core of this was the idea that information wants to be free - and the tension behind that idea is still at the root of what it means to be extremely online today.  BitTorrent is the world’s largest decentralized protocol. Bitcoin is the second largest. Bitcoin is a revolutionary idea but miners are too centralized and the energy footprint is growing. Bram’s vision for Chia addresses these two perceived weaknesses.

974: Why BitTorrent Founder Bram Cohen Wants A Greener Crypto

The Tech Talks Daily Podcast

Bram Cohen is an American computer programmer, best known as the author of the peer-to-peer (P2P) BitTorrent protocol, as well as the first file-sharing program to use the protocol, also known as BitTorrent which grew to over 40% of Internet Traffic. Bram is also the co-founder of CodeCon and organizer of the San Francisco Bay Area P2P-hackers meeting, the co-author of Codeville and was also featured in 2005 Time's 100 Most Influential People. But here in 2019, he is the CTO, Chairman & Co-Founder of Chia. The Chia Network is a decentralized open-source global blockchain which is less wasteful, more decentralized, and more secure. It is inspired and similar to the Bitcoin blockchain, but in Chia the resource is not computing power, but disk space. To achieve this, the “proofs of work” used in Bitcoin are replaced by “proofs of space”, so disk-space becomes the main resource. This is combined with “proofs of time” to come to a decentralized “Nakamoto-style” consensus that validates transactions. I wanted to find out more about the man who created BitTorrent sitting in his living room on a laptop, as an unknown programmer in San Francisco. But more importantly the incredible work he is doing right now with Chia. Bram Cohen joins me on the Tech Talks Daily podcast, to talk about all this and much more.
