Technical Intro to Blockchain (Part 3)

“When you store data, store it three times.”

— Tom Dwyer of Extropy.io

Learn how to code a smart contract!

On the 10th of November 2020, the Oxford Blockchain Society hosted its fourth event of the year — an Intro to Blockchain (for technical folk) in collaboration with OxWEST. This event was led by Tom Dwyer of Extropy.io — a blockchain development consultancy in Oxford and is part of a four-part series on blockchain. Join us for a look into how blockchain works and how to start understanding and using the technology. We’ll go through everything from smart contracts to running nodes and building DApps (decentralised apps).

About the talk

Tom took us through how to build a smart contract and a simple DApp that interacts with it plus an interface that displays relevant data using Solidity, NodeJS, Express, Ganache, HTML and more. We created an automated item tab. We then went on to learn how to store and retrieve files using the InterPlanetary File System (IPFS). We were lucky to have Tom stay at the end for a brief chat on how he got involved in coding blockchain smart contracts and his background.
