He is the author of the leading mining blog hashingit.com, VP of Software at PeerNova and had a long career in chip manufacturing including at Qualcomm. We talked about dynamics in the mining market, security issues with Bitcoin's design and his data-informed views on the blocksize debate. Topics covered included: - How he became interested in mining and what metrics he finds most interesting - How miners would be affected by a blocksize increase - The flaws in Satoshi's design of the reward scheme - Why transaction fees will not make up for the block reward decrease in 2016 and why that will lessen the security of Bitcoin - The long-term role of Bitcoin as a settlement network - The problem with accepting 0-conf transactions - The future of mining and why 21 Inc's plans seem nonsensical Links mentioned in this episode: - Dave's Personal Blog : http://bit.ly/1H1cKhS - Waiting for blocks : http://bit.ly/1N1rs7x - The Myth of the Megabyte Bitcoin Block : http://bit.ly/1fVpHO4 - The Future of Transactions Fees : http://bit.ly/1MF6wWG - Bitcoin SF Devs Seminar: A deep dive into understanding Bitcoin mining hashrates [video] : http://bit.ly/1gzSHfh - Dave's company PeerNova: http://bit.ly/1KJm0Ww Review us on iTunes and WIN a Free T-Shirt!

In recent times, as consumer adoption of Bitcoin payments has been underwhelming much of that attention has shifted elsewhere. Nevertheless, companies keep working hard on making the vision of a universal, global payment system a reality. Among those companies, one stands out as the top contender to compete with existing payment systems: Bitnet. Funded with a heavy warchest and the company is ran by veterans of Visa and Cybersource, a company started in 1994 to help merchants accept credit cards online that was sold to Visa in 2007 for $2bn. They have been working behind the scenes to get Bitcoin to break through with merchants. CEO John McDonnell joined us for an important discussion of how online payments work today, why they are broken and how Bitcoin will revolutionize the industry. Topics covered included: - The story of Cybersource and payments in the early day of the internet - The pain points with online payments for merchants and consumers today - The role of the different actors such as payment processors, card networks, merchants and issuing banks - The niches where Bitcoin payments could break through first - Why coming from inside the payment industry provides Bitnet with a huge advantage - Why they are focusing on Payment Service Providers instead of acquiring merchants directly - His view on BitLicense and how it will affect Bitcoin payment processors Links mentioned in this episode: - Bitnet http://bit.ly/1gxb6ZU - Richard Gendal Brown: Why the payment card system works the way it does http://bit.ly/1K1fxc8 - Richard Gendal Brown: Simple explanation of fees in the payment card industry http://bit.ly/1O6nhrG - Wikipedia e-commerce credit card payment systems http://bit.ly/1MpykuX Sponsors: - Ledger Nano: Smart card security for your Bitcoins - Get 10% off your first order when you use the code EB09 at http://ledgerwallet.com (valid until 09/30/15) - CoinCap: Crypto-currency market cap rankings, charts, and more coincap.io/#/ Show notes: http://epicenterbitcoin.com/podcast/087 YouTube: https://youtu.be/PdUWzNcFJx4 Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

But with decentralized technologies, there is a real question whether these monopolies can be built or whether the monopolies will end up being publicly owned goods (like Bitcoin) that can't be monetized directly. William Mougayar, who is an experienced tech executive and angel investor, has been writing extensively about these issues and was one of the investors in OB1, the venture-backed company launched by the founders of the decentralized market place Open Bazaar. He joined us for a discussion of the cryptocurrency space, Ethereum, Open Bazaar and monetizing decentralized technologies. Topics covered included: - Bitcoin as the new, thin cloud - His long-term predictions about where the space is going - What kind of business models are the most promising - Why he chose to invest in OB1, the company behind Open Bazaar - What the state of Venture Capital in the cryptocurrency space is Links mentioned in this episode: - Predictions in Cryptography, Blockchains and Consensus Protocols http://bit.ly/1giM8gJ - The Old Cloud is Dead, Welcome the New Cloud http://bit.ly/1H3AZGk - The Business Imperative Behind the Ethereum Vision http://bit.ly/1JPRgms - An Operational Framework for DAOs http://bit.ly/1NKQKr4 - Union Square Ventures: Introducing OB1 http://bit.ly/1S1YCFe - Peter Thiel: Competition is for Losers http://on.wsj.com/1NKRbS8 Sponsors: - Shapeshift: Buy and sell alt coins instantly at http://ShapeShift.io - Vaultoro: Trade gold to Bitcoin instantly and securely starting at just 1mg at http://vaultoro.com Show notes: http://epicenterbitcoin.com/podcast/086 YouTube: https://youtu.be/ROQDaagEDi8 Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

Some think this is a non-sensical idea fabricated by those spineless enough to want to appease regulators and but clueless enough to miss the whole point of cryptocurrencies. But others believe that Bitcoin is unsuited for a lof of 'Bitcoin 2.0' applications and that permissioned ledgers have wide-reaching potential to increase efficiency and transparency. Tim Swanson joined us for an important discussion of permissioned ledgers. He's among their best-known proponents and has recently published a whitepaper discussing how they work and looking at different startups in the space. Topics covered included: - Why the 'blockchains without bitcoin' idea is so controversial - Why it is strange that KYC is done widely on Bitcoin users but not on the validators - Why even semi-decentralized blockchains can provide big efficiency gains - Why the 51% attack possibility is an obstacle for the use of the Bitcoin as a settlement network - Why financial institutions don't care about censorship resistance but do care about irreversibility Links mentioned in this episode: - Tim Swanson: Permissioned Distributed Ledgers Whitepaper http://bit.ly/1QLDrMn - Tim Swanson: Needing a Token to Operate a Distributed Ledger is a Red Herring: http://bit.ly/1JdB94z - Robert Sams: No, Bitcoin is not the future of securities settlement http://bit.ly/1eCRz9P - JP Koning: Why bitcoin has failed to achieve liftoff as a medium of exchange http://bit.ly/1GhoxmQ Sponsors: - Shapeshift: Buy and sell alt coins instantly at http://ShapeShift.io - Vaultoro: Trade gold to Bitcoin instantly and securely starting at just 1mg at http://vaultoro.com Show notes: http://epicenterbitcoin.com/podcast/084 YouTube: http://youtu.be/k3pM8vB2QYc Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc
