EB131 - Stefan Thomas & Evan Schwartz: Building The Internet Of Payments With Interledger
May 16th, 2016 by
epicenterbitcoin One of the foundational problems in payment networks is that they are mostly uninteroperable. This problem exists at all levels, from consumer payment solutions like PayPal, to national and multi-national banks. This complexity is brought on by the proprietary nature of payment networks, and moving value from one to another requires a negotiation between parties on which common payment network to use in a transaction. We saw similar problems in the early days of the Internet, assembled aroun... Read More -
EB130 - Erik Voorhees: Fooling The Fox - The Story Of The Shapeshift Hack
May 9th, 2016 by epicenterbitcoin In the short history of the Bitcoin industry, there has been an impressive amount of high profile hacks, ranging from a few hundred thousand to many millions of dollars. In all of these, customers, Bitcoin users, where robbed of their funds because poor security policies, negligence, incompetence, or plain old scamming. Recently, the cryptocurrency conversion service ShapeShift fell victim to a hack in which over $200,000 of company funds were stolen, initially by an employee, and then by a ... Read More -

EB128 - Jed Mccaleb: Stellar And The Vision Of An Open Financial System
April 26th, 2016 by epicenterbitcoin When Jed McCaleb discovered Bitcoin, there didn't even exist an online marketplace to trade the cryptocurrency yet. The experienced founder who had earlier started file sharing site eDonkey, acted fast and started the first Bitcoin exchange MtGox which he later sold to now-infamous Mark Karpeles. Jed later founded the pioneering Ripple project before leaving to start Stellar. We discussed his journey through the industry and the ambitious plans Stellar has to create an open financial syst...

EB126 - Trent Mcconaghy: Scalable Public Distributed Databases With BigchainDB
April 12th, 2016 by epicenterbitcoin One of the major drawbacks of Bitcoin is its low transaction throughput. Maxing out only a handful of operations per second, there have been many proposals to scale it up so that it can compete with existing distributed database technologies. As the blockchain's demand continues to increase, it's unclear if the Bitcoin protocol will ever be able to handle thousands, if not millions of transactions per second. BigchainDB is taking a different approach. Rather than trying to scale up blockchai... Read More -
EB125 - Florian Glatz: Defining A Legal Framework For Decentralized Autonomous Organizations (DAO)
April 5th, 2016 by epicenterbitcoin The relatively new concept of a Decentralized Autonomous Organization (DAO), is often praised as a new type of organizational structure that has no identifiable owner or owners, and whose actions are automated and determined solely by a pre-defined set of rules. Views on DAOs differ widely. On one hand, members of the Bitcoin/blockchain space often portrayal them as AI-like swarm organisms, free from the shackles of nation-states, and that can act at will regardless of laws or regulation. On... Read More -
EB124 - Rune Christensen: Maker Dao Ethereum's Decentralized Central Bank
March 30th, 2016 by epicenterbitcoin The challenges Bitcoin's wild volatility represents for achieving mass adoption have made the necessity for stable cryptocurrencies apparent long ago. With Ethereum applications, the problem is even more apparent as many use cases from predcition markets to insurance are impractical using the even more volatile ether. Maker DAO is an ambitious attempt to solve the problem by building a bank-like system to issue a value-stable currency on Ethereum. Rune Christensen joined us to discuss the nee... Read More -
EB123 - Brock Pierce: From Digital Goods To Digital Currency
March 21st, 2016 by epicenterbitcoin We're joined by Brock Pierce, Chairman of the Bitcoin Foundation, investor and all around emblematic figure of the Bitcoin ecosystem. Brock tells his story, from his early beginning a entrepreneur in his teens, to the massively successfull video game industry businesses he built in the early 2000s. As Chairman of the Bitcoin Foundation, he gives us his perspective on how the Foundation's role has evolved over time and its areas of focus going forward. Brock also weighs in the recent debat...

EB122 - Zooko Wilcox: Zcash - An Open Financial System With Privacy
March 21st, 2016 by epicenterbitcoin For Zooko Wilcox-O’Hearn, part of the cypherpunk movement since the early 1990s, the vision of a decentralized financial system that has both openness and privacy has existed since long before Bitcoin. After many failed attempts, Bitcoin proved that that vision could be achievable. But Bitcoin also failed to deliver on the privacy features as blockchain analysis allows tracing movements and deanonymizing many users. Zooko joined us to discuss his project Zcash, a fully anonymous cryptoc... Read More -
EB121 - Winston Moore & Jeremy Stephen: Barbados, Bitcoin And Central Banking
March 7th, 2016 by epicenterbitcoin For orthodox Bitcoiners central banks are often seen as the incarnation of evil. But , alas, in the case of two Carribean central banking economists the feeling of reprehension wasn't reciprocated. Winston Moore and Jeremy Stephen were formerly associated with the Central Bank of Barados and fascinated by the potential of cryptocurrencies, they explored the consequences of their central bank holding Bitcoin as part of their international reserves. They joined us for a discussion of central b... Read More -
EB120 - Maciej Olpinski: Solving The Economic Mismatch Between Content And Attention
February 29th, 2016 by epicenterbitcoin The problem around content monetization is one which content producers are constantly trying to solve. At the core of this problem is a mismatch between supply and demand. Content, which is increasingly abundant, is captured by human attention, which is in limited supply. The volume of content being produced is growing at staggering rates while total human attention remains flat. Our guest, Maciej Olpinski, argues that the current content monetization model is outdated, broken and is in n... Read More -
EB119 - Adam Gibson: A New Kind Of Auditing - Cryptographic Proof Of Online Accounts
February 23rd, 2016 by epicenterbitcoin A pioneering feature of Bitcoin is verifiability of transactions: It is designed to enable low-power devices and high end computers alike to be able to verify occurrences on the blockchain. This observation led our guest, Adam Gibson, to wonder why webpages aren't so easily verifiable as a Bitcoin transaction? Can I prove to you that I have certain bank account balance over the internet? Why do we submit photocopies of passports rather than furnishing a cryptographically verifiable proof ... Read More -
EB118 - Manu Sporney: W3C, Making Payments A Web Standard
February 16th, 2016 by epicenterbitcoin A typical online transaction today isn't very different from how it was done 25 years ago at the dawn of the Internet. In fact, online payments haven't changed much at all. When we want to pay for something online, we copy very sensitive credit card information into a form on a website and trust that website to capture it securely and make proper use of it. If this seems like an old and antiquated way to pay, that's because it is, and it costs billions of dollars per year in security and fra... Read More -
EB117 - Eric Lombrozo: Upgrading Bitcoin With Segregated Witness
February 8th, 2016 by epicenterbitcoin In the midst of the heated blocksize debate one could be forgiven to think that there is very little Bitcoin developers are able to agree on. Yet, when core developer and Blockstream co-founder Pieter Wuille introduced the concept of segregated witness at the Scaling Bitcoin conference in Hong Kong most of the Bitcoin community quickly rallied behind the proposal. Eric Lombrozo, CEO of wallet company Ciphrex and responsible for running the segregated witness testnet, joined us to discuss... Read More -
EB116 - Eli Ben-Sasson: Zero Knowledge Proofs
February 1st, 2016 by epicenterbitcoin Zero Knowledge Proofs are methods of providing cryptographic proofs to another party while keeping some information secret. The simple concept of ZKP offer tantalizing possibilities: Banks could prove solvency without revealing depositors. Governments could prove the fairness of an election without compromising privacy. Computer science professor Eli Ben-Sasson joined us to discuss where blockchains and cryptocurrencies intersect with Zero Knowledge Proofs and related technologies such as... Read More -
EB115 - Matan Field: Backfeed and the Social Operating System for Decentralized Organizations
January 25th, 2016 by epicenterbitcoin The idea that in the future tokens will play a crucial role in networks and organizations to incentivize decentralized collaboration and reward contribution is not new. It's the original decentralized autonomous organization idea that has informed many projects that have been on the podcast (Swarm, Ethereum, Factom, Storj, etc). For Matan, the vision originally led to found decentralized ride-sharing application LaZooz. One year ago, he left LaZooz to found Backfeed, which is building the to... Read More -

EB113 - Jae Kwon, Dustin Byington & Ethan Buchman: Tendermint - Private Modularized Blockchains
January 11th, 2016 by epicenterbitcoin As blockchain technologies mature, new protocol specifications are emerging, which take unique approaches to software design and how consensus is achieved. We have talked about [Multchain](https://epicenterbitcoin.com/podcast/107/) and [OpenChain](https://epicenterbitcoin.com/podcast/102/) in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus laye... Read More -
EB112 - Casey Kuhlman: Permissioned Blockchain And Disrupting Industrial Application Design
January 6th, 2016 by epicenterbitcoin Permissionable blockchains have gained much attention from enterprise this past year, and specifically, the traditional fiance and FinTech sectors. As new protocols emerge and the technology is matures, it is becoming apparent they are simply a new class of database, one which integrates business logic (smart contracts) and a consensus layer (PoS, PoW, etc). Casey Kuhlman is the CEO of Eris Industries, a company which specializes in building permissioned blockchain systems for enterprise... Read More
