The computer scientist has been part of the Bitcoin community since 2009 and just recently turned off his last miner after 6.5 years! We talked about the current scalability debate and what his research indicated what blocksize could reasonably be handled today. We also discussed his proposal for Duplex Micropayment Channels. Like the Lightning Network, Duplex Channels use a network of payment channels to enable cheap, instant and trustless offchain transactions. The proposal, which he is currently implementing, is one of the most promising approaches to scaling Bitcoin. Topics covered included: - How losing 9000 btc got him on the front page of the New York Times - The scaling Bitcoin debate and what blocksize could be handled today - How payment channels work and could be used for off-chain transactions - The advantages Duplex Micropayment Channels have with regards to privacy - The differences between Duplex and the Lightning Network - Whether off-chain transactions could work on Ethereum as well Links mentioned in this episode: - Christian Decker's ETH homepage http://bit.ly/1XlB6Wr - A Fast and Scalable Payment Network with Bitcoin Duplex Micropayment Channels [PDF] http://bit.ly/1N4co7k - Bitcoin Meets Strong Consistency [PDF] http://bit.ly/1N4cgVe - Information Propagation in the Bitcoin Network [PDF] http://bit.ly/1YpurwR - Epicenter Bitcoin Lightning Network Episode http://bit.ly/1MxUYCP Sponsors: - Shapeshift: Buy and sell alt coins instantly at http://ShapeShift.io Show notes: http://epicenterbitcoin.com/podcast/106 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-106 Epicenter Bitcoin is hosted by Brian Fabian Crain, Sébastien Couture & Meher Roy - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

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 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-087 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
