What are NFTs?

A Non-Fungible Token (NFT) is used to represent ownership of a unique digital asset. Each NFT consists of in-built documentation using blockchain technology. This technology allows you to view the NFT’s background, ownership history and transaction values.

About STREET ART ALIVE NFT collection

Artflow NFT’s STREET ARTALIVE NFT collection is inspired by the creative works of street artists from around the world. The list of artists includes well-known D*Face recognised for his British Urban contemporary art and large-scale murals. ELLE from NYC whose work is evocative, alluring, lavish, outrageous, purposeful, and informative and she is considered to be one of the top touring artists of the world. Dscreet is known for his captivating signature owl character that is displayed across many streets and alleys of East London, and beyond. Tom Gerrard focuses on suburban life and the everyday man. There are many other artists, with more to come, including Malarko Alex Senna

Each NFT is based on a real-life piece of street art, that can be (or could have been, if it has since been painted over) found on a wall or building around the world, and have been turned into edgy and cool animations that are begging to be displayed on a screen at someone’s home or office. Each artwork has an interesting story behind it, so does each of the street artists, particularly as many started off working under the cover of darkness, as their craft was often breaking a few rules

You can buy the STREET ART ALIVE NFT collection is on Opensea and Rarible

The STREET ART ALIVE collection has been minted with Manifold, which is used by many big name artists in the NFT Space. Manifold enables web3 creators to have true creative ownership, preserve on-chain provenance, and interoperate with all major NFT marketplaces. We have used a creator-owned minting smart contract which has the benefits of

  • Authenticity — true provenance for creators, so collectors can be assured the NFTs they purchase are 100% genuine, backed by the creator.
  • Interoperability — works with existing ERC-721 NFT platforms, so recognized on all open NFT marketplaces and
  • Extensibility — unique, creator-approved NFT applications which will allow Artflow to introduce new mechanics, partner with third parties platforms and provide more functionality in the future.

How do I buy an NFT?

Step 1) Open a wallet i.e MetaMask

Step 2) Purchase Ether (ETH) from an exchange, through MetaMask, or through OpenSea

Step3) Purchase NFT on OpenSea marketplace

We recommend using the crypto wallet Metamask. You are able to use other crypto wallets, such as Coinspot or Binance, however the steps below to purchase an NFT will be via Metamask. MetaMask is safe for use on public and private Wi-Fi as no third party can access the funds because of the encrypted connection.

Also, Opensea now allows you to pay for NFTs using a credit cards in selected countries. Check to see if credit card is available for you.

How to set up a Metamask wallet on your mobile:

See the steps below for iPhone / Android users:

1. Go into the AppStore/PlayStore to download the MetaMask App.

2. Click on Get Started, then MetMask will prompt you to create a password.

3. Create a good password and also remember it for later, as if you want to access the MetaMask in the browser then you will require the same password and "seed phase".

4. Now, MetaMask will give you “Secret Recovery Phase”, please copy it somewhere because in the next step you will be required to re-enter the same “Secret Recovery Phase” in the correct order of the words from one to twelve.

5. This Phase is also important for login into a browser or app, that’s why keep it safe and secure. Anyone with this phase can log in to your wallet.

6. Re-enter the “Secret Recovery Phase” in the exact order from one to twelve, if you mess up the order the Phase will become incorrect.

7. You are now successfully logged in to your MetaMask App from Android or iPhone.

4. Create a strong password for your wallet.

It is the only way to recover your funds should your device crash or your browser reset. We recommend you write it down. The most common method is to write your 12-word phrase on a piece of paper and store it safely in a place where only you have access. Note: if you lose your seed phrase, MetaMask can’t help you recover your wallet and your funds will be lost forever. Never share your seed phrase or your private key to anyone or any site, unless you want them to have full control over your funds. Click on ‘Next’.

What is a Crypto Wallet?

Crypto wallets keep your private keys – the passwords that give you access to your cryptocurrencies – safe and accessible, allowing you to send and receive cryptocurrencies like Bitcoin and Ethereum. They come in many forms, from hardware wallets like Ledger (which looks like a USB stick) to mobile apps or Chrome extensions like Metamsk, which makes using crypto easier for purchase of NFT.

Why are Crypto Wallets Important?

Unlike a normal wallet, which can hold actual cash, crypto wallets technically don’t store your crypto. Your holdings live on the blockchain, but can only be accessed using a private key. Your keys prove your ownership of your digital money and allow you to make transactions. If you lose your private keys, you lose access to your money. That’s why it’s important to keep your hardware wallet safe, or use a trusted wallet provider like Metamask.

Hardware wallets: Keys are stored in a thumb-drive device that is kept in a safe place and only connected to a computer when you want to use your crypto. The idea is to try to balance security and convenience.

Online wallets: Keys are stored in an app or other software – look for one that is protected by two-step encryption. This makes sending, receiving, and using your crypto as easy as using any online bank account, payment system, or brokerage. Online wallets offered by a major exchange like Ethereum based wallet provider Metamask are the simplest way to get started in crypto and offer a balance of security and easy access. (Because your private info is online, your protection against hackers is only as good as your wallet provider’s security – so make sure you look for features like two-factor verification.)

Using an app like Metamask gives you easy access to your crypto holdings. You can:

- Manage all your digital assets in one secure place

- Control your own private keys

- Send and receive cryptocurrency to and from anywhere in the world

- Interact with usernames rather than long, hexadecimal “public key” addresses

- Browse dapps (decentralised finance apps)

- Shop at stores that accept cryptocurrency

- See our section here for how to set up a Metamask wallet.

What is Blockchain Technology?

Blockchain technology is a system of recording transactions and tracking assets in a business network via an immutable ledger. Blocks form a chain of data as an asset moves place to place or changes ownership. They determine the exact time and sequence of transactions, and everytime a new transaction occurs on the blockchain, a record of it is added to every user's ledger. Blocks are linked securely together to prevent being altered, and ensure security of the data within the chain.

What is Ethereum?

Ethereum is a blockchain based computing platform with its own cryptocurrency called Ether (ETH) or Ethereum and its own programming language called Solidity. The platform allows developers to build and deploy decentralised applications. As of September 2022, Ethereum is second in market value only to Bitcoin.

Why are we using the Ethereum Blockchain?

As with all blockchain technology, the computational power and processes required for token minting and processing requires large amounts of energy. As there has been an uptake of NFT’s in the art world, questions have been raised about the environmental impact of minting and processing these proof-of-work blockchain-powered tokens.

We are using Ethereum as they plan is to slash their energy consumption dramatically by the quarter 4 of 2022. The plan involves an upgrade to the network that will reduce the Ethereum network’s energy use by over 99%. The Ethereum "merge" will switch the network from Proof of Work model, where cryptocurrency miners use high-powered computers to complete complex mathematical functions, to a Proof of Sake consensus mechanism to verify transactions

Ethereum is also considered to be the most secure blockchain for NFTs.

What are Gas Fees?

Gas fees are transaction fees that are paid to Ethereum miners who provide the computer power necessary to keep the network running. Every time you bid or purchase an NFT, you’ll need to have extra ETH in your crypto wallet so that you can pay for gas. Gas fees on the Ethereum blockchain are continuing to be reduced with the optimisation of the blockchain.
