Summary

The panel explains a couple of ways to earn passive income in the blockchain. The first is building applications or dapps (decentralized applications) on the blockchain that charges users a very small fee for the services. Gregory McCubbin explains how a transaction works on the blockchain and how it requires cryptocurrency to be spent in order for a transaction to take place. Roman Storm shares his experience with his multisender app. Roman explains how his multisender app allows users to send tokens to a mass of recipients with ease giving him a very small amount of ether in return for this service. Gregory explains why users would be so eager to use the app and save time and pain. Without Roman’s app, development-able users would have to write their own code to send multiple transactions at once and those users without the knowledge to write their own code would be forced to send each transaction manual which would take hours in many cases. Gregory also points out that people are there to spend money and are used to paying fees when it comes to handling money. Bruno Duarte Brito and Roman discuss how this all works with walleting and maintaining security.

The second way to earn passive income is to become a validator. Gregory starts by explaining that a miner was someone who helped run the blockchain by creating new records, finalizing transactions or writing it to the blockchain. The new consensus algorithm uses validators, which Gregory tells us anyone can do, you don’t have to be a developer to be a validator. Roman explains how validators run nodes, receiving block rewards and transactions fees in return for their services. The panel discusses ways to become a validator. Becoming a validator in a well-established blockchain can be tricky without a lot of capital but Roman and Gregory give a few ways to get your foot in the door, including helping a current validator with security and attracting someone with capital with your skills running a node. Becoming a validator for a new blockchain may seem like is the suggestion the panel gives; if that blockchain takes off you can see a great return. Bruno and Roman discuss what is involved in running a validator service, what it looks like, how it works, and the cost involved. Roman explains that it is very important to research potential networks as each of them varies in what they want in a validatory and suggests that everyone give it a try even if only on a test network because there is so much developers can learn about the blockchain just by running a node.

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.

Summary

The panel starts by discussing the advantages blockchain gives in the payment world and how it works. Double spend is defined and how blockchainsolves 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.

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.
