NFT marketplaces allow digital creators to sell their work as NFTs and earn ownership and cryptocurrencies in return. The top NFT marketplaces include OpenSea, Raible, Foundation, and Super Farm. NFT marketplaces provide high liquidity through instant trading of NFTs, which are often kept as collateral or exchanged for other cryptocurrencies. They also allow developers to limit scarcity by restricting the number of specific rare items created.
NFTs (non-fungible tokens) allow digital art, music and other files to be bought and sold on the blockchain, with proof of ownership. Popular artists like Grimes, Kings of Leon and Mike Shinoda from Linkin Park have sold their art and music as NFTs, with Grimes raising $6 million and Shinoda selling a song teaser for $33,000. The music industry sees opportunities for ongoing revenue from reselling collectible digital music and art files, as well as getting paid in cryptocurrency. However, mainstream adoption may depend on educating older generations about cryptocurrency.

This document provides an overview of non-fungible tokens (NFTs). It defines NFTs and discusses their history from colored coins in 2012 to recent growth in 2021. Common use cases for NFTs like art, games, and collectibles are described. The ERC-721 and ERC-1155 token standards are explained. Hands-on examples are provided for creating an ERC-721 contract from scratch and minting/selling an NFT on OpenSea.
A non-fungible token or NFT is a type of digital token. This type of token can’t be interchanged or replaced as every token comes with unique attributes. Understanding how NFTs work is very important. However, to do that, we need to look into the fundamentals behind this technology.
NFTs use public blockchain platforms to function. At this time, Ethereum is the most popular public platform that many of the NFT projects are using for storing or minting NFTs. Due to using blockchain, transparency regarding NFT ownership is high, as anyone can see the ownership status. ERC-721 and ERC-1155 are the only 2 token standards that can help create NFTs.
To help you better understand how NFT works, we at 101 Blockchains offer an array of courses that will help you better comprehend the topic. More so, we have an exclusive course on NFT, where we cover every single element within the ecosystem.

This document provides an overview of non-fungible tokens (NFTs) and discusses some associated copyright issues. It defines NFTs as digital assets on a blockchain that represent real-world objects like art, music, in-game items and videos. While NFTs claim to transfer ownership, they do not necessarily confer copyright ownership. Issues discussed include authorship problems with user-generated content, the transfer of rights, licence terms, platform enforcement over infringing content, and implications for an artist's moral rights.

Ethereum is a decentralized blockchain platform that allows developers to build decentralized applications and smart contracts. It uses a cryptocurrency called Ether to incentivize nodes to run the Ethereum Virtual Machine. Ethereum aims to be a "world computer" that can execute programs called smart contracts in a decentralized manner. Smart contracts are written in programming languages like Solidity and deployed to the Ethereum blockchain through transactions. Ethereum uses a proof-of-work consensus algorithm called Ethash, though it plans to transition to proof-of-stake. Developers can build and test smart contracts using tools like Remix, MetaMask, and Truffle.
Non-fungible tokens (NFTs) are unique digital assets that are verified on a blockchain network, allowing for the creation and ownership of one-of-a-kind digital items, such as artwork, music, videos, and other types of digital content. They are important because they provide a way for digital creators to monetize their work and establish ownership, scarcity, and authenticity of their creations. NFTs have also gained popularity as a form of investment and collectible item, with some NFTs selling for millions of dollars.

Un misterioso scienziato inventa nel 2008 un protocollo informatico che consente per la prima volta di realizzare un sistema di pagamento decentralizzato, sicuro e autonomo in quanto svincolato da ogni autorità di controllo. Nel 2009 nasce il Bitcoin definito da alcuni non come il denaro di Internet ma piuttosto come la Internet del denaro. In queste slide ripercorriamo rapidamente la storia e le caratteristiche di questa tecnologia emergente.

Indicatori Ambientali e loro Rappresentazione GraficaFederico Bo
Viene proposto un
grafico - ispirato al Dashboard of
Sustainability, un tool gratuito e personalizzabile creato dal
Consultative Group on Sustainable Development Indices (CGSDI) - per la visualizzazione di indicatori ed indici ambientali nel
contesto del progetto Piccoli Comuni dell\'APAT, denominato ‘semaforo
ambientale’, grafico in grado di trasmettere un’informazione
immediata sullo stato delle risorse naturali e delle attività
antropiche di un comune, permettendo anche un benchmarking sia
spaziale, con medie provinciali per esempio, sia temporale,
analizzandone l’evoluzione attraverso gli anni.
Hypothesis For A Web Science Degree CourseFederico Bo
This document proposes a degree course in Web Science to study the behavior and properties of complex systems formed by people, services, and software agents operating on the global communication infrastructure of the Web. A graduate in Web Science would have the ability to analyze and model networked systems at different scales, define theories and methodologies to systematically study the "Web discipline", and design tools and applications tailored to the Web. The proposed degree course would be interdisciplinary and cover topics such as network theory, social computing, data mining, psychology, and economics as the Web is a social, information, economic and technical system.
Ipotesi per un Corso di Laurea in Scienze del WebFederico Bo
Come potrebbe essere organizzato un Corso di Laurea in Scienze del Web.
Dando per scontato l’approccio multidisciplinare, quali sono le materie da inserire? Quali i percorsi formativi da predisporre? Quali sono le conoscenze e le competenze che uno studente uscito da questo corso di laurea dovrebbe possedere?
1. NFT
I «gettoni» digitali che stanno trasformando
arte, collezionismo, gaming ed entertainment

2. Cos’è una blockchain
Una blockchain è una sorta di database crittografato
distribuito.
Ogni nodo della rete ha una copia del database,
costantemente concordata e sincronizzata con le altre.
Si possono aggiungere dati, non cancellarli.
3. Cos’è una blockchain
Sulle blockchain vengono memorizzati dati che rappresentano
criptovalute e/o altri beni digitali (puri o rappresentativi di beni
fisici): le transazioni di questi beni (asset) sono il «cuore» di una
blockchain.
Un bene (asset) è rappresentato da un «token» (gettone),
simile a un’azione di borsa.
Un token può rappresentare un barile di petrolio, un diamante,
una bottiglia di vino, un brano musicale, un’immagine jpg…
4. Cos’è una blockchain
Esistono blockchain:
pubbliche, a cui tutti possono accedere. Bitcoin ed Ethereum
sono implementate su blockchain pubbliche.
private, in cui per accedere occorre avere credenziali di
accesso. Sono soprattutto blockchain create per le aziende, le
business network o per scopi specifici come le supplies chain.
5. Smart Contract
Sulle blockchain evolute (tipo Ethereum) è possibile
implementare contratti digitali «embeddati» nel codice.
Sono chiamati «smart contract» e permettono l’esecuzione
automatica di certe azioni in base a determinate condizioni.
6. Smart Contract
if «merce arrivata» AND «merce integra» AND «consegna
puntuale»
then «trasferisci 10 ether a ejgg3siii8222ple»
else if «consegna non puntuale»
then «trasferisci 8 ether a ejgg3siii8222ple»
7. Beni fungibili e non fungibili
Un bene fungibile è un bene inter-scambiale con altri dello
stesso tipo.
Sono fungibili:
- il denaro: una moneta da un euro è uguale — per scopo e
valore — a tutte le altre monete da un euro; un bitcoin è
uguale a ogni altro bitcoin
- il grano, il barile di petrolio
- un libro pubblicato in grande quantità
8. Beni fungibili e non fungibili
Un bene non fungibile è un bene che non può essere sostituito
con altri appartenenti allo stesso tipo.
Sono non fungibili:
- una casa
- un diamante
- un libro con firma dell’autore
9. Gli oggetti digitali, in generale, sono per
loro natura fungibili: ne possono facilmente
essere fatte infinite copie.
Questo ha limitato l’espansione dell’arte digitale e del
collezionismo di oggetti fatti di bit.
Autenticazione, certificazione di proprietà, compravendita
risultavano incerti e poco affidabili.
10. ERC721
Nel 2017, la blockchain pubblica Ethereum ha visto
nascere uno standard specifico e aperto, l’ERC721, che
permette di creare token non fungibili ovvero
NFT (Non Fungible Token)
* Altre blockchain stanno implementando i loro NFT
11. ERC721
Possiamo immaginare uno di questi NFT come un
contratto — anzi uno smart contract — che implementa
un certificato di autenticità e di proprietà associato a
un certo bene digitale (o fisico).
12. Con questo sistema si riescono a creare
unicità o scarsità anche per gli oggetti
puramente digitali, rendendoli
collezionabili.
13. Come funziona (arte digitale) 1/2
L’utente/artista si iscrive a una piattaforma (Rarible,
Nifty Gateway, Foundation ecc.)
Sceglie se l’oggetto digitale/opera sarà unico o in
numero limitato (decide numero copie).
Avviene il «minting» (conio): l’utente fa l’upload
dell’oggetto/opera e contemporaneamente si crea un
NFT associato. Nota: il minting costa.
14. Come funziona (arte digitale) 2/2
L’NFT contiene un «puntatore» all’opera.
Viene messo, di solito, all’asta. Le piattaforme
percepiscono una percentuale sulle vendite.
Chi si aggiudica l’NFT ne diventa proprietario. A sua
volta può rivenderla.
L’NFT conterrà la «cronologia» dei proprietari
(identificati di solito da stringhe tipo fre57st64238kiia o
alias).
15. Dove si trova l’opera?
On-chain: è nella blockchain insieme all’NFT. Caso
raro. Memorizzare nella blockchain costa tanto.
1 MB circa 120.000 euro (su Ethereum)…
Off-chain: il caso più comune. L’NFT contiene un link
(URL) all’indirizzo dove è memorizzata l’immagine: un
server proprietario, una cloud o l’IPFS.
16. Cos’è l’IPFS?
L’IPFS (Inter Planetary File System) è un protocollo e
una rete peer-to-peer per l’archiviazione e la
condivisione di dati in modo distribuito.
Un file (come un’opera digitale) è identificato in questa
rete da un’ «impronta digitale» univoca, una stringa di
lunghezza fissa (tipo jbjb45j12knsss98). Cambiare un
solo bit nel file significa cambiare completamente
questa stringa.
17. Campi di applicazione NFT
Arte
Oggetti Collezionabili (es. figurine calciatori)
Gaming (es. items per videogiochi)
Musica
Moda
Giornalismo
Audiovideo
…
18. Gli NFT possono essere associati anche
a oggetti fisici: grafica/multipli, biglietti
per mostre/spettacoli/concerti, vinili,
capi di abbigliamento, bottiglie di vino
ecc.
19. Gli NFT permetteranno al creatore
dell’oggetto/opera di ricevere una
percentuale sulle rivendite degli
oggetti associati.
È ancora raro trovare piattaforme che abilitino
questa possibilità. Si sta studiando un
ERC-721 Royalty Standard.
