The Past Present & Future of Cryptocurrency | Coinbase Co-Founder Fred Ehrsam

In the episode 'The Past Present & Future of Cryptocurrency | Coinbase Co-Founder Fred Ehrsam' of 'The After On Podcast', host Rob Reid engages in a comprehensive dialogue with Fred Ehrsam, co-founder of Coinbase, the largest consumer-friendly service for storing and trading cryptocurrencies. The conversation is structured to educate both beginners and experts about cryptocurrencies, blockchain technology, and their potential future impact on society. Fred Ehrsam shares his journey from playing video games, studying computer science, to trading currency at Goldman Sachs, all of which led him to co-found Coinbase in 2012. They discuss the inception of Bitcoin in the context of the financial crisis, Satoshi Nakamoto's identity, and the breakthroughs that allowed Bitcoin to solve the double-spend problem, creating a trustless, decentralized financial system.

Fred delves into the technical workings of Bitcoin, explaining the roles of miners, the public-private key cryptography, and the concept of proof of work. The episode further explores the limitations of Bitcoin as a transactional currency due to scalability issues and its rising transaction fees. Instead, Bitcoin's role has evolved toward being an investment asset and a store of value, drawing parallels with gold. The conversation then shifts to Ethereum, introduced by Vitalik Buterin as a response to Bitcoin's limitations. Ethereum's Turing completeness and the introduction of smart contracts allow for a broader range of decentralized applications, potentially transforming various industries.

The discussion also touches upon the governance of cryptocurrencies, the explosion of initial coin offerings (ICOs), and the emergence of new cryptocurrencies with specific purposes, such as privacy-focused Monero and Zcash. Ehrsam reflects on the potential for blockchain technology to revolutionize systems beyond finance, including AI and identity management, emphasizing the importance of native blockchain applications over those that merely adapt existing services to the new technology.
