1/ Update on our #openmetaverse course with @punk6529:

Week 1 & 2 material has now been minted as NFTs!

See below for details and next steps 👇
2/ Four NFTs have been minted to date:

Week 1 presentation
Week 1 lecture video
Week 2 presentation
Week 2 lecture video
3/ You can see everything on OpenSea (and other marketplaces)

opensea.io/collection/met…

(You’ll also see some placeholder tokens there - ignore these for now)
4/ Everyone who had minted the course access token in time, has already been airdropped the week 1 presentation NFT to their wallets.
5/ We will be shortly releasing a claim website where everyone will be able to claim all the course NFTs for free (plus Ethereum gas costs).
6/ You do NOT need to buy these NFTs on any secondary market.

But, you can start creating your personal educational Ethereum wallet by claiming these (and future) material from this historic course!
7/ Please note that, depending on your computer/browser setup, some of the NFTs may not show properly in OpenSea or other marketplaces.
8/ For example, Chrome blocks the presentation, but plays the lecture video correctly. Firefox works well for both.
9/ Also, you may notice some delay in the video for week 2. This is due to the file size and the time Arweave needs to assemble the various file chunks from its nodes.

Who said decentralization would be easy? 😉
10/ If you have any problem accessing the NFTs on Etherscan, OpenSea, LooksRare, etc., you can always access all course material directly on Arweave, in the course website, and on the UNIC GitHub (links below)
11/ Arweave Presentation 1: What is an NFT?
arweave.net/RQSe3S0q14ao_U…
12/ Arweave Presentation 2: Copyright and Provenance in NFTs
arweave.net/EsEmloBwcs9ojd…
13/ Arweave Video 1: What is an NFT?
arweave.net/tqghPMjuypZvOx…
14/ Arweave Video 2: Copyright and Provenance in NFTs
arweave.net/t6Js3LJY0FI3oA…
15/ UNIC GitHub (all course presentations)
github.com/UniversityOfNi…
16/ META511 website (all lecture videos)
unic.ac.cy/openmetaverse/…
17/ Finally, don’t forget today’s live session with @punk6529 at 5pm (EEST).

See you in the OM!

1/ Learning resources for week 2 of UNIC's #crypto MOOC, this week taught by none other than @aantonop, are now online for our students.

Let's dive into the contents - 🧵👇
2/ In week 2, we introduce the theoretical underpinnings of #blockchain and #Bitcoin by discussing how Satoshi Nakamoto solved (under assumptions) the hitherto considered unsolvable Byzantine Generals Problem (BGP)
3/ To implement decentralised money, one would need to create a decentralized ledger of transactions that contains a complete record of money transfers and proof of ownerships.

#decentralized here means without any single party operating, maintaining, or controlling the ledger.

1/ Our “Intro to Digital Currencies” MOOC is about to begin (next week).

Over the next 12 weeks, @aantonop, @polemitis and I will cover all things crypto. As always, the course is 100% open and free for all to attend.

Let’s dive into the contents of week one - 🧵👇
2/ Week 1: we set the scene by providing “A Brief History of Money”.

This could be a full university course on its own, of course, but we will cover the basics in just one session. So, excuse us for some necessary over-simplication in what follows!
3/ Money has 3 functions
Medium of Exchange (MoE): an instrument facilitating trade of goods/services
Unit of Account (UoA): a unit of price measurement so things are comparable from a value standpoint
Store of Value (SoV): a mechanism to save excess income for future consumption
