Just spent the past hour reading about Solana and rollups on Twitter. 99% of it went over my head but it was interesting πŸ˜†. Links to some of the more interesting threads I read below...

Here's my smooth brained understanding of Solana and rollups
1/ First off, a rollup is a L2 scaling solution. With rollups, a bunch of transactions are executed off-chain, and their data is posted on L1. This increases throughput, because instead of L1 processing 10 individual txs, it can process 1 "rolled-up" tx.
2/ So is Solana planning on having rollups on top of its L1? No ❌

The 🍬 Candy Machine 🍬 is a program built by @redacted_j and @baalazamon that's commonly used to mint Solana NFT collections.

This thread is about how the program works (not how to use the Candy Machine for your own collection).

Let's go! πŸ‘‡
1/ First, if you want a simpler, shorter explanation, check out this comic!

2/ Now, some preliminary resources.

If you don't understand Solana's account model, check out this thread

gm πŸ„ Excited to share @TheMycoverse, the project @petrichorate and I are working on!

We're starting with a mushroom-inspired NFT collection (b/c mushrooms are awesome), but our larger goal is to help onboard more artists and creators into web3.
Right now, getting into web3 as an artist is hard πŸ˜΅β€πŸ’«.

Which blockchain should you choose? Which marketplace should you list on? How do you make an NFT collection? How do you airdrop NFTs to people? How do you market yourself?
We're building a community that cares about helping artists. With that community, we'll create tools and resources that make it easy for any artist or creator to get started with web3.

How do NFT whitelists work on Ethereum? It's pretty simpleβ€”let's take a look at the @smilesssvrs smart contract to see how they did it πŸ‘‡

1/ The contract has a state variable called "_mintStatus."

This determines whether minting is only open to people on the whitelist (Acts 1-4), or is open to the public (Public 1-2).

Each status is associated with a minting limit. E.g. during Act 1, one person can mint 9 NFTs. Image
2/ Only the owner of the smart contract is allowed to change the status. Image

PDAs, or program derived addresses, are one of the trickier #Solana concepts πŸ€”. They're also something that every Solana dev should understand.

In this thread, I'll go over what they are, and why they're useful πŸ‘‡
1/ First of all, if you don't know how Solana's account model works, check out this thread. It's only 5 tweets!

2/ Now, onto PDAs, or program derived addresses.

The name is pretty self-explanatoryβ€”a PDA is an address derived from a program.

The address points to a data account, which can hold state.

How do #Solana tokens work? What are the Solana equivalents of ERC20 and ERC721? Let's find out πŸ‘‡
1/ In Ethereum, fungible tokens use the ERC20 standard, and non-fungible tokens use the ERC721 standard.

Each ERC20 token has its own smart contract, and each NFT collection has its own ERC721 contract.

Things work quite differently in Solana land.

2/ In order to understand Solana tokens, you need to understand Solana's account model.

Check out this thread if you're unfamiliar.
