Gerardo Lemus is a data science consultant at Lamat UK and joins Wendy this week on Would You Data Scientist to explain in simple terms what a blockchain is, what a token is, how NFTs are generated, and what is web3. He also tells us about his work in data and what advice he would give to someone pivoting into the field. Apologies for Gerardo’s creaky chair!

KEY TAKEAWAYS

• Blockchain is simply put, a ledger of numbers denoting where something is coming from, where it is going, and how much of it there was. It needs to be maintained and updated constantly. This ledger then compares to other ledgers and comes up with a consensus.
• A crypto token is a virtual currency token or a denomination of a cryptocurrency. It represents a tradable asset or utility that resides on its own blockchain and allows the holder to use it for investment or economic purposes.
• A non-fungible token is a non-interchangeable unit of data stored on a blockchain, that can be sold and traded.
• It’s not a surprise that we see many large companies as unethical, they exist to make as much money as possible, and to do that they will naturally take any opportunity to cut corners.

BEST MOMENTS

’One of the problems with blockchain is that you have the fanatics and the sceptics’

‘I built a model in 5 minutes but it took me hours and hours to explain how I did it’

‘Develop your web3 skills now so you’ll be at the top of your game when it comes’
