Muneeb Ali & Ryan Shea: Onename – Bringing Decentralization to Identity with Blockchain ID
A brilliant fact about crypto-economic blockchains is that they enable the construction of naming systems that transcend limits imposed by Zooko’s triangle. Traditional naming systems such as human names, Domain Name System (DNS) and Facebook profile names are subject to Zooko’s triangle and cannot be secure, human memorable and decentralised at once. For instance human names such as Meher Roy are human-memorable and decentralised but not secure (nothing prevents hundreds of people being called Meher Roy). Domain Names like are secure and human-memorable but require a central authority to hand out names.
OneName leverages Bitcoin to build a Global Identification system called blockchain ID. Blockchain IDs for users can be associated with real world identity data such as social media profiles, government issued papers etc. In this episode we converse with Ryan Shea and Muneeb Ali, co-founders and leaders of OneName, Blockstore and BlockStack. They explain the rationale and vision behind their push for a Global Decentralised Identification and Verification system.
Topics covered in this episode:
Zooko’s triangle and how Bitcoin breaks the triangle
The general idea behind blockchain ID, how it works and its component transactions
Why OneName migrated their blockchain ID system from the Namecoin to the Bitcoin blockchain
Technical design of Blockstore and how it enables decentralised storage and association of large datasets to blockchain IDs
Vision and use cases for Decentralised Identity, authentication and identity verification.
The notion of Probabilistic Identity

Juan Benet: IPFS – Decentralizing the Web with the Inter-Planetary File System
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 in this episode:
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

Esteban Ordano & Manuel Aráoz: Streamium – Pay-Per-Second Video Streaming for Indie Producers
One of the key innovations of Bitcoin is the ability to easily implement payment channels. A number of use cases have been discussed or demonstrated, among which is the idea of pay-per-use. This is particularly useful when charging for things like WiFi or streaming video by the second. With this in mind, one could imagine a line of communication between two peers, where data flows in one direction and payments flow in the other.
This is the idea behind Streamium, a free and open-source service which allows content creators to stream live video directly to viewers, and get paid instantly. We’re joined by Manuel Aráoz and , the two brilliant software engineers from Argentina who created Streamium. They have worked together on numerous Bitcoin projects these past few years, including ProofOfExistence.com, Faradam, Decentraland, RelayStore, and actively contributed to the BitCore javascript library.
Topics covered in this episode:
The current state of Bitcoin in Argentina
The general idea behind Streamium, how it works and its technical components
How payment channels are implemented in Streamium and its various use cases
The Faradam project
The prospect of alternative content funding models made possible by Bitcoin micropayments
Proof-of-existence and what innovations blockchain technologies brings to data notarization
The Decentraland project and the vision for a blockchain-based virtual reality

Paul Sztorc: Truthcoin & Prediction Markets – From Information-Overload to Crowd Intelligence
Prediction markets are considered one of the most promising applications of blockchain technology. Although the concept and some early implementations have existed for years, decentralized prediction markets present a number of advantages to their centralized counterparts.
joins us to discuss Truthcoin, a “Peer-to-Peer Oracle Protocol which absorbs accurate data into a blockchain so that Bitcoin-users can speculate in Prediction Markets”. We dive deep to explore the advantages of decentralized prediction markets, their various real-world applications, and their potential to revolutionize the creation and propagation of knowledge in our society.
On this episode, we are thrilled to introduce a new co-host on Epicenter Bitcoin, Meher Roy. He has a biochemical engineering background and previously worked as an adviser to HyperLedger. Since discovering Bitcoin, he spends most of his free time understanding blockchain technology and its potential impact on our lives. We’re confident that Meher will bring a high level of understanding and critical thinking to the topics we cover, and we’re certain our listeners will be as happy as we are to have him on the show.
Topics covered in this episode:
What are prediction markets and why they are useful
The mechanics of prediction markets
The potential for prediction markets to provide useful aggregation to today’s abundant information
The parallels between crowd intelligence and artificial intelligence
The different components of Truthcoin and the state of the project
How Truthcoin differs from other decentralized prediction markets

John Clippinger: Developing a Social Ecosystem of Trusted, Self-Healing Digital Institutions
It is often said that technology is neutral. It’s certainly commonplace for Bitcoin to be thought of as such. In reality, technologies may be characterized as an embodiment of human intention, and therefore, cannot be considered as culturally or politically neutral. At least, this is the opinion of our guest, . A research scientist at MIT Media Lab and CEO of ID3, a nonprofit which aims to deploy a new generation of trusted digital institutions, John has spent the last seven decades researching the interaction between technology and society.
He joins us for a fascinating discussion on the flaws of our institutions in present day society and how we can leverage technology to build a new social ecosystem.
Topics covered in this episode:
The political values of Bitcoin
The idea of cooperative currencies
The current state of identity and data ownership, and how it may be improved
The governance of decentralized technologies
How cybernetics and self-organizing systems may be applied to governance
The Open Mustard Seed framework

Adam Back: Why Bitcoin Needs a Measured Approach to Scaling
As the debate about forks, the blocksize and decision making in Bitcoin continues, we are joined by Adam Back. Adam is best known for his invention hash-cash which became one of the fundamental building blocks of Bitcoin. He is also the inventor of the sidechains concept and founder and president of Blockstream, the single biggest employer of Bitcoin core developers.
With Adam we talked about the different blocksize proposals and how a decentralized cryptocurrency should be governed in general. He is an influential conservative voice in the current debate and has been warning that a rapid increase of the blocksize could undermine the decentralization of Bitcoin.
Topics covered in this episode:
Adam’s concerns with Bitcoin XT and the approach by Gavin Andresen and Mike Hearn
Why Adam favors a slower blocksize increase to preserve decentralization
How Bitcoin will function as a settlement network in the medium-term with the bulk of transactions going through the Lightning Network or sidechains

Simon Dixon: How Bank to the Future is Rethinking Finance
Ever since the financial system collapsed in 2007, the call for alternatives has grown louder. Bitcoin itself can be seen as such an alternative. Simon Dixon’s search for a way to put capitalism on a sounder financial footing began before Bitcoin with a focus on equity crowdfunding. Since then he has built Bank to the Future into an innovative crowdfunding business that takes an aggressive contrarian stance. He has also launched an investment fund focused on cryptocurrencies together with Max Keiser called Bitcoin Capital.
He joined us for a fascinating discussion about the flaws of the banking system, Bitcoin and the search for alternatives.
