System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

So you want to display a Metaplex NFT

This guide will attempt to give an overview of the technical/coding steps that are required to render a Metaplex NFT with any programming language/platform. I'll attempt to write it a programming language-agnostic manner; you'll need to fill in the particular methods of performing the steps with your coding language of choice.

For the purposes of discussion, we'll call the Solana account that holds the Metaplex NFTs the "NFT-Account."

Step 1: Call getTokenAccountsByOwner

The first thing you need to do is call the getTokenAccountsByOwner JSON RPC method as documented here:

	import numpy as np

	# data I/O
	data = open('input.txt', 'r').read() # should be simple plain text file
	chars = list(set(data))
	data_size, vocab_size = len(data), len(chars)

	//SLIDING WINDOW METHOD
	var lengthOfLongestSubstring = function(s) {

	let count = 0;

	let i = 0;
	let j = 0;
	let end = s.length;
	let set = new Set();
