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 Episode links: Intentional Naming System Zooko's triangle Why Onename is Migrating to the Bitcoin Blockchain Blockchain ID Organization of Schemas Blockstack BlockStore This episode is hosted by Meher Roy and Sébastien Couture.

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 Episode links: Streamium Faradam Decentraland Proof of Existence The Mental Accounting Barrier to Micropayments by Nick Szabo Manuel Aráoz's About.me profile Esteban Ordano's personal website This episode is hosted by Meher Roy and Sébastien Couture.
