Support the show, consider donating: 17QpAaTfUn4kTCwjFcoCHvxjrs8EAxmNkh (http://bit.ly/1tvum0a)
Attracting over 70 of the world's biggest financial institutions to its consortium in just over a year, R3 has accomplished a formidable task. Aiming to rethink the fabric of the financial system, they first conducted experiments testing blockchain platforms for their member and last year began developing their own distributed ledger platform: Corda.
The effort to build Corda was lead by R3 CTO Richard Brown and the former Bitcoin developer and R3 lead architect Mike Hearn. In a wide-ranging discussion, we covered the vision of the project and why it represents a radical departure from existing blockchain platforms.
Topics covered included:
- The origin story of R3
- Why existing blockchain designs didn't meet their needs
- How the R3 team lead a design effort to develop a new platform from scratch
- The business problem Corda is aiming to solve
- The components of Corda's architecture
- How Corda handles privacy
- Notaries and preventing double spends
- Open sourcing Corda and the plan to join Hyperledger

The idea of using the Bitcoin blockchain to represent and track the ownership of off-chain assets is almost as old as Bitcoin itself. One of the startups that is pursuing this vision is Berlin-based Ascribe, which allows creators to register ('ascribe'), transfer and archive digital art.
Ascribe CTO Trent McConaghy joined us for a fascinating discussion of their ambitious goals to enable a so-far elusive secondary market for digital art, help creators monetize their work and ultimately retrofit an entire ownership layer to the internet.
Topics covered included:
- Why ownership in the internet is broken
- How Ascribe wants to realize the vision of Project Xanadu of an internet with bi-directional links and baked-in copyrights
- How the SPOOL (Secure Public Online Ownership Ledger) protocol works
- The components of the Ascribe tech stack
- How Ascribe will crawl and similarity-match the entire internet to retrofit an internet of ownership
- Why Ascribe focuses first on the digital art market

We've made it to episode 100! Our guest for our celebratory episode is Juan Benet, inventor of the Inter-Planetary File System and founder of Protocol Labs. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. The possibilities for IPFS could range from distributed cloud hosting to websites without central servers to even replacing HTTP. It's a project as audacious as any we've had on the podcast and Juan did an outstanding job explaining the technology and vision.
Topics covered included:
- Why HTTP is broken and how IPFS could complement and ultimately replace it
- The different technologies IPFS is based on including DHT, Git, Bittorrent and SFS
- How IPFS could enable the 'permanent web' by distributing file storage
- Content-addressing and how hosting works on IPFS
- Mutable content and the Interplanetary Naming System (IPNS)
- Filecoin and incentivizing hosting on IPFS
- Why IPFS is a great fit for smart contracts
- How he wants to build and monetize core internet protocols with his company Protocol Labs

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. Credit cards and social security numbers weren’t developed with the Internet in mind, and other identifiers such as logins and passwords aren’t well suited truly secure authentication and authorisation.
We’re joined by Tim Pastoor, Founder of 2way.io, to discuss how we can improve control of our identities using concepts borrowed from Bitcoin. Tim walks us through how people could better manage different identities and build reputation networks using Identifi, a global address book protocol invented by Martti Malmi, one of the very first Bitcoin users. We also talk what role this system could play in the future as autonomous agents and artificial intelligence become more prevalent.
Topics we discussed include :
- The history of identity systems and how traditional identity systems are broken
- How the invention of Blockchain technologies changed the way we think of identity
- The Identifi protocol and how it works
- How we can build reputation through Webs of Trust (WoT)
- The future of identity and how Identifi could provide ID for IoT, robots, autonomous agents and artificial intelligence
- 2Way.io and what the company is trying to achieve

When Robin Hanson invented the concept of prediction markets almost thirty years ago, he felt he had stumbled on a concept with huge implications. By allowing people to bet on the likelihood of future events, prediction markets promise to allow better forecasts and better decision making.
Research into the area has been vibrant, culminating in Hanson's concept of Futarchy: A prediction-market based governance system. At the same time, the real-world applications have been few and far.
Hanson, an associate professor of economics at George Mason University, joined us to discuss his invention, futarchy and the challenges of disruptive technology.
Topics covered included:
- How prediction markets can surface information
- The history of prediction markets
- How futarchy works
- Whether futarchy could settle the blocksize debate
- Why prediction markets failed to get wide adoption
- How Bitcoin is facing a similar adoption challenge

Few crypto projects have gotten as much attention and caused as much controversy as Steem. The blockchain-based social media platform launched early this year and managed to gain real user traction building up a vibrant community of contributors. The Steem token quickly entered bubble territory reaching a market cap of almost $400m and losing 90% of its value since.
Steem Co-Founder and CEO Ned Scott joined us to discuss the ambition of the project and its short tumultous history. We also discussed some of the accusations against Steem and its unorthodox launch.
Topics discussed in this episode:
- How Steem was launched out of the BitShares community
- The different components and tokens of the Steem system
- How Steem rewards content contributors
- The controversial Steem launch and criticisms of the project
- Why Steem transitioned from Proof-of-Work to Proof-of-Stake
- The potential disbalance of power due to the Steem distribution
- How Steem managed to build a vibrant user community

As content becomes more and more abundant and immediately available at our fingertips, our limited attention is a barrier for those whose business it is to attract and harness it. In this context, large (social) media companies understand that attention is a scarce commodity, and, as has been demonstrated, those who control attention wield enormous power over our society.
We're joined by Greg Meredith, CTO of Synereo, to talk about how this new Blockchain platform rebuild the attention economy. In a sense, Synereo is to attention, what Bitcoin is to money, in effect, removing intermediaries from the transaction between those who have attention, and those who wish to attract it. Greg, also gives his insights on how functional programming languages could allow for verifiable computational smart contracts.
Topics discussed in this episode:
- Greg's background as a mathematician and his work on Microsoft's BizTalk Process Orchestration
- How he transitioned into the crypto-currency space
- What is Synereo and what the project is trying to achieve
- Greg's thoughts on the attention economy and how it is fundamentally broken
- Synereo's technology stack
- How Vlad Zamfir's Casper consensus algorithm influenced Synereo
- Rholang, Synereo's functional smart-contracting language
- Synereo's economic model and product roadmap

Among the dividing themes in the Bitcoin space is the idea of public versus private blockchains. While some argue that private and permissioned blockchains can offer better scalability and lower latency for enterprises, others insist the Bitcoin blockchain will offer the best level of security and robustness longterm. Recently, projects have emerged that propose the best of both worlds by leveraging both off-chain and on-chain transactions.
This is the idea behind Openchain, an “open source distributed ledger technology, suited for organizations wishing to issue and manage digital assets in a robust, secure and scalable way.” Openchain uses a client-server model where there is only one authoritative validating node. Read-only observer nodes keep the central node honest by auditing transactions in real time. About every 10 minutes, a copy of the Ledger, and its transactions, is hashed and inserted into a Bitcoin transaction so that it can be fossilised in the blockchain.
We’re joined by Flavien Charlon, the one-man operation behind Predictious, Coinprism, the Open Transactions Protocol and now Openchain. We talk about this fascinating new software, which aims to offer enterprises a digital ledger protocol that is highly scalable while enjoying the benefits of the Bitcoin blockchain for immutability.
Topics discussed in this episode:
- Flavien gives an update on Coinprism and his other projects
- The Openchain protocol and what it’s trying to achieve
- The technical architecture of Openchain and the client-server model it implements
- How Openchain uses the Bitcoin blockchain to “anchor” transactions into every block
- Openchain’s consensus model
- The ability for Openchain to interoperate with other ledgers and blockchains
- Flavien’s thoughts on what the ecosystem might look like in 10 years
