Zeppelin Co-Founder and CTO Manuel Araoz joined us to discuss his journey from building one of the first non-financial Bitcoin applications in 2012 to improving development and security practices for Ethereum smart contracts. We discussed the OpenZeppelin framework, a library of audited smart contracts as well as their new project zeppelin_os. Through on-chain, well-vetted and upgradeable smart contracts zeppelin_os aims to make developing Ethereum applications both easier and more secure. Topics covered in this episode:  Manuel’s journey in the blockchain space from proof of existence to BitPay to Streamium to Zeppelin Why Manuel moved away from a pure Bitcoin focus to working on Ethereum Why Zeppelin focuses on smart contract security How smart contract security evolved since the start of Ethereum The OpenZeppelin framework of audited Ethereum contracts Why zeppelin_os and standardized, upgradeable on-chain contracts are the next evolutionary step The core component of zeppelin_os: Kernel, SDK and markeplace The ZEP token and its role in zeppelin_os  Episode links:  Zeppelin Website OpenZeppelin Framework zeppelin_os zeppelin_os Whitepaper  This episode is hosted by Brian Fabian Crain.

Manuel Aráoz: Zeppelin and the Evolution of Smart Contract Development

Esteban Ordano

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.
