0xMarkoWhen to use arrays vs mappings in Solidity?
Arrays are useful when you know the size of the collection in advance, and you need to be able to iterate over the elements in a specific order. Mappings are useful when you don't know the size of the collection in advance, and you need to be able to quickly lookup values. Here are a few specific scenarios where you might choose to use one over the other: 1. Use an array when you need to store a collection of items that need to be accessed by index. 2. Use a mapping when you need to asso...
0xMarkoEthereum vanity addresses
Ethereum vanity address is a one-of-a-kind customized address that has portions of it chosen rather than being created at random. Why would you create a vanity address? First of all, it looks cool. The second thing it can help you with is to reinforce your brand and make you more noticeable. How to generate your own vanity address? Creating a vanity address is a straightforward trial-and-error process. When performing high-risk cryptographic operations, such as private key creation, it is imp...
0xMarkoBored Ape Yacht Club: Smart Contract Breakdown
Bored Ape Yacht Club (BAYC) is a popular NFT collection created by Yuga Labs. In this post, we’ll go over BAYC smart contract code. The source code is available on EtherScan.ERC721BAYC is implemented as an ERC721 token, a standard that defines a set of functions that a smart contract must implement in order to be considered a compliant ERC721 token. These functions include the ability to transfer tokens, approve other addresses to manage your tokens, and check token ownership.ERC721 interface...

AI art has been around for 50 years, but it recently became a buzzword.
What is it exactly and why is it useful?
AI-generated art is a game changer in the world of digital art. Algorithms analyze existing styles, images, & data to create new pieces of art. Algorithms can also mimic a specific artistic style for a consistent, recognizable look & feel for brands or projects.
AI-generated art enables experimentation & exploration of new styles & techniques that may not have been possible with traditional methods. It has the potential to revolutionize the way we create & consume art, making it more accessible, efficient & exciting!
Why would you generate art?
Low cost & quick production of high-quality art makes it accessible to a wider range of people & applications.
Automates repetitive tasks, freeing up artists to focus on creative & strategic aspects of their work.
How to generate art?
There are many tools, but I really like Midjourney. Midjourney is an independent AI art generator that is open for public use and free to join with a Discord account. Simply enter a few words as a prompt in the channel, and let Midjourney do the rest.
AI and machine learning will create a unique image just for you.
Once you’re satisfied with what the bot returns, you can upscale the image and download it or send it to yourself. Plus, you can also explore a gallery of amazing images created by other users.
Here is a quick start guide for Midjourney
