Identity is probably one of the most important constructs in our society. In our modern world, protecting one’s identity has become complex, as we no longer rely solely on governments to prove who we are. In addition, most identity sources can be easily compromised.

November 30, 2015Gideon Greenspan: MultiBit – The Blockchain is a New Database Paradigm
Gideon Greenspan, a computer scientist and CEO/Founder of the Israeli startup Coin Sciences, joined us for a discussion of their private blockchain platform MultiChain. Besides diving into the popular question of what’s the point of a private blockchain, we covered his earlier colored coins implementation as well as his view that blockchains are best understood as a novel database paradigm.

How Gideon got involved in the blockchain space
Their colored coins implementation MultiSpark and why it failed to get traction
Why he saw a market for an open-source private blockchain platform and started MultiChain
What mining diversity is and how it is used for consensus in MultiChain

November 23, 2015Christian Decker: Scaling Bitcoin with Duplex Micropayment Channels
Christian Decker is a PhD student at ETH Zurich, where he is currently finishing up the world’s first PhD thesis entirely about Bitcoin. 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 in this episode:
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
