The third episode of our crypto series with David Stancel, our cryptocurrency expert and CTO at Fumbi, is here! The first episode focused on basic crypto terms & explanation of how it works; the second episode was about Ethereum and smart contracts. The third episode – as always, moderated by our host Helene Panzarino – brings the topic of decentralised finance and NFTs!

So first of all, what is decentralised finance?

“As the name suggests, it is a parallel financial universe that consists of decentralized smart-contracts-based applications that perform functionalities that we usually see in financial institutions, banks, and so on.” – David Stancel

And so what is the difference between “standard” functionalities and the ones in blockchain?

“As they are performed in DeFi  (decentralised finance), the pieces of code are uploaded on some blockchain networks, such as Ethereum. They are basically unstoppable in these distributed networks, impossible to temper with. They are fully automated and together they create a beautiful, very exciting universe of applications and actually create products that we didn’t have here before.” – David Stancel

Use cases of decentralised finance are various – first came decentralised exchanges (so-called order book exchanges, AMM (automated market makers) which are one of the greatest innovations so far in DeFi); then there are for example lending protocols or synthetic stocks. All of these run on smart contracts and thus different rules apply to them – they might not have the same limitations or restrictions that are in place in regular trading venues.

NFTs – non-fungible tokens

“Fungible tokens are — by their definition — interchangeable: each Bitcoin is the same as every other Bitcoin, much like every US dollar is equal to every other US dollar. NFTs on the other hand are not interchangeable: each token is unique, which gives non-fungible tokens a unique set of traits or properties that enable them to do all sorts of other things.” – David Stancel

The hype came in 2017 with CryptoKitties when it paralized the whole Ethereum network. Currently NFTs are popular among artists or gamers.

And the future of NFTs according to David? They will be present in segments such as education and will create digital assets for example for university diplomas. Also thanks to COVID, the whole world is getting digitized so there is a lot of space for blockchain, decentralised finance or NFTs to leak into our everyday lives.
