Panel

• Gregory McCubbin
• Bruno Duarte Brito

Summary Gregory McCubbin and Bruno Duarte Brito answer the question “Which blockchain should I use?”. “It depends”’ is their answer. Their first advice is to ask yourself, “Why am I using a blockchain?”, “What are my goals?”, and “Do I even need a blockchain?”. Gregory begins with discussing Ethereum, being very familiar with Ethereum he teaches it on his website and in his Bootcamp. Ethereum, he describes as very versatile, with an active development community. Bruno explains the differences between public and private blockchains, the biggest one being who controls the blockchain. Using Hyperledger as his example blockchain, Bruno describes the benefits of controlling who sees what information while still maintaining security and transparency.   The idea of decentralization is considered and how this will sway your decision on the blockchain you might use for your app. Gregory explains what decentralization means and how some blockchains compromise on decentralization based on their goals. Bruno and Gregory share the most common and most influential use cases for both private and public blockchains. They are that most use cases are financial, but not all. Bruno shares a few use cases that are not all about transactions, including IBM’s Food Trust, supply chain problems and Dubai’s smart city initiative. Links

Panel

• Gregory McCubbin
• Roman Storm
• Bruno Duarte Brito

Summary The panel starts by discussing the advantages blockchain gives in the payment world and how it works. Double spend is defined and how blockchain solves this problem is explained. Using a financial model the panel discusses how blockchain works. Privacy and security are considered as the panel discusses how blockchain makes it safer to make financial information public. The 51% attack problem is defined and the panel explains how blockchain combats these types of attacks. They address how blockchain works from a more technical perspective and why it is so hard to change the history in blockchain. Proof of work and proof of stake algorithms are explained and compared; blockchains that use each of these are mentions. The panel compares private and public blockchains.  Links

Summary The panel introduces themselves in this exciting new podcast. Roman Storm, a former software engineer, wanted to build a startup and heard about Bitcoin. After building himself a bitcoin wallet and later moved the Ethereum, he eventually began security consulting for companies in the blockchain space. Bruno Duarte Brito has a very unique story having never owned a cryptocurrency or a wallet; he found his way to the blockchain by requesting to be put on a blockchain project at his company. Bruno mostly works with Hyperledger and blockchain for business. Gregory McCubbin, a self-taught developer, started following cryptocurrency prices and wanted to learn more. Looking for online resources, he found the materials available scarce. After learning blockchain he built up Dapp University as a resource for future blockchain developers.    The panel discusses the importance of where you are starting from and what is bringing you to the blockchain. Bruno discusses the importance of knowing the blockchain theory. The panel advises getting some cryptocurrency or trying a test network and outlines the benefits of using cryptocurrency to understand how the blockchain works. Blockchain, as a relatively new technology, holds many possible use cases for the creative and curious developer. The panel discusses some of the use cases being seen and explored, including blockchain for business, cryptocurrency, securing medical records and Dubai’s smart city project. Links
