What information to see about the creation of NFT tokens?

Question

Algorithms

Interested in NFT tokens. All that Google gives out on this issue is which sites, where you upload something and it seems like you get a token. (Not deepened).

I am interested in the question of how to create an NFT at the program level.
Without access to the stock exchange and sale. Create purely for yourself and figure out how it works in the process.

Answer 2

Considerations about NFT are set out below, if you read a lot of letters for a long time, here is an example of creating an NFT on the Ethereum test network (not on your own node) using a smart contract. Stack - nodejs

I'll start the considerations
A big quote from. https://vc.ru/crypto/28314-sozdaem-svoy-erc20-toke...

Create your own Ethereum-based ERC20 token in 2
minutes there is no magic from the technical side of holding an ICO. [Skip]
create our Ethereum-based ERC20 token as quickly as possible.
Solidity/pyEthereum (Ethereum-based token). Using the knowledge and / or standard for writing smart coins ERC20 (in fact, the source of the coin with many blackjack options) deploy the contract.
To be honest, I was lying. You don't need to understand Solidity. To launch your token, you need to take the source code of the ERC20 token, change a couple of lines (since 2017, everything has become very complicated and storing the token in the blockchain is very expensive) and upload the contract to the network by one of the clients (off.client Ethereum/Metamask/etc). The address of the NFT will be known only to those whom you tell (please correct the experts)
End of quote i.e. you have to be a node on the network.
If there are no nodes, but there is a wallet, but not on your node, then
next, if it’s free, you will need Jedi ownership of the crypto exchange API
Free - with checkmarks and a mouse in the gui. It’s not free to create NFTs in curated platforms (these are all opensea, binance exchanges and how many more there are 100500+)
Next, I will give some details on the free way to create NFTs using non-curated platforms without using code and creating a smart contract on your own, the exchange does this for you (it’s free does part of the exchanges)
For example OPENSEA.IO SDK
https://github.com/ProjectOpenSea/opensea-js similar and also free rarible.com
Quote:
Currently, there are many NFT trading platforms in the crypto space. Uncurated platforms have evolved into a viable alternative to curated platforms as they provide free access for everyone. To load NFTs on them, users only need to register and pay a transaction fee to create a token.
Another quote:
One of the non-curated platforms is OpenSea, which allows users to mint and trade NFTs, view data about them, and check statistics. OpenSea, created in 2017, houses almost all crypto art collections, as well as a huge amount of items from many popular blockchain games. The platform has a fairly user-friendly creation interface that allows users to quickly and efficiently create non-fungible tokens for free.
Please note that
if you sell NFTs, opensea will take a commission.
In order for everything to be generally even freer - either a contract from your node, or create and register your own crypt, and create NFTs in it.
