In this episode of BlockTalk, watch a discussion on Bitcoin and Lightning technology with Samson Mow, the CSO of BlockStream. They cover Bitcoin and Lightning technology as well dive into how companies like BlockStream are innovating on top of the Bitcoin protocol.
With BitCoin prices on the rise again, the hype machine has turned its focus back onto the technology. In a few days, expect the rally to retreat again and pundits to say something along the lines of “Blockchain has no practical use.” They are, of course, wrong and Siraj Raval explains (and demontrates!) why in this video.
Healthpass is a secure cloud store for all your health records! This serves patients by giving them one place to store and view all of their health data across all providers globally. It serves providers by ensuring that health records are stored securely via a blockchain and allows them to see a patients previous health history easily. To build this app I used Node.js, Firebase, Bitcoin’s Blockchain, Paypal, Stripe, Tesserect.js, BioBERT, and a health data visualization library called hFigures. The reason I built this app is to give you an idea on how a “bitcoin” startup would look practically, programmatically, and visually. I hope this inspires you to build something cool and even managed to fit a rap about SHA-256 into it. Enjoy!
In this TEDx talk, Jaspreet Bindra explores the promise of Blockchain and how it could radically transform identity, agriculture, money, energy, governance, and pretty much everything else, especially in the emerging countries.
This TEDx talk demystifies blockchain as never before, and explains how it can change the world around you… Jaspreet Bindra is a digital transformation and Blockchain expert. Until very recently, he was the Chief Digital Officer of $20bn Mahindra Group; and he continues as their Digital Adviser. He speaks, writes, teaches and consults on Digital Transformation and Blockchain, and is currently building a company around the same. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at
In this first of a multi-part episode, learn how to use the VS Code extension – Azure Blockchain Development Kit for Ethereum, to scaffold out a basic Solidity project, compile it and deploy that contract to a private Azure Blockchain Service, and to a public testnet using Infura.
In this episode of BlockTalk, they showcase an IoT use case which highlights how to use leverage the power of Cosmos DB to manipulate IoT data within a Cosmos DB and use that data in smart contracts via the Ethereum Logic App connector.
Here’s an interesting perspective on what blockchain and open source have in common and how they will enrich each other in the years to come.
The many similarities between blockchain and the open source are not just a coincidence. Analysts and developers believe that the new technology is picking up from where open source left off. There is a limit to what companies can share with open source. Open source is not known to open up live systems and it can never open their data.
Integration with smart contracts is a common topic with developers. Whether with apps, data, messaging or services there is a desire to connect the functions and events of smart contracts in an end to end scenario. In this episode, we look at the different types of scenarios and look at the most common use case – how to quickly expose your smart contract functions as microservices with the Ethereum Blockchain Connector for Logic Apps or Flow.

In this episode of Block Talk, learn how to use the Ethereum Logic App connector to push contract data into an Azure Search index. This makes contract data available to a wide range of Enterprise applications via simple search queries.

There are multiple scenarios where having attestable documents and media is valuable. Media doesn’t belong on the blockchain, but hashes of the media and metadata can be added. In this video we demonstrate a blockchain devkit accelerator that shows how to hash a media file, uploaded to a service like Adobe Creative Cloud, and its metadata and add it to a blockchain.
