The DAS reduces the cost to mint a basic NFT from ~0.012 SOL → ~0.003 SOL
I assume NFT compression (basically, moving more data off-chain to save costs) will reduce minting costs even more, but estimated costs for compressed NFTs are not mentioned in the docs

Solana NFTs 101 🎓
🌟 Part 1: Account overview 🌟
Solana NFTs are composed of at least three accounts:
If your instruction takes in an "authority" account, make sure the account has signed the transaction.
Why? Because only the owner of the "authority" account can sign for it—but anyone can pass in the account as a non-signer.

The @metaplex team is working on a new metadata standard for both fungible and non-fungible tokens.
It's backwards compatible and has official support for on-chain collections. And it's currently being tested in devnet.
For more details, see below 👇
1/ First, and perhaps most importantly, this new standard is backwards compatible.
This means NFTs that use the old standard will still function properly (e.g. be displayed properly in Phantom) once the new standard rolls out.

If you're writing Solana instructions involving tokens/NFTs, please require the token's mint account to be passed!
Otherwise, if you query for the mint's transactions, transactions that include your instruction may not show up... more on this 👇
For example—the regular "Transfer" instruction of the SPL Token Program does not take in the mint account.
Thus, if you transfer an NFT using this instruction, it WON'T show up on that NFT's Solana Explorer page.

Solana vs. Ethereum L2s, a UX comparison
1/ A lot of people are excited about ZK-rollups, and for good reason.
However, from a UX experience, ZK-rollups aren't too different than existing L2s. E.g. Polygon already offers low fees and fast transactions.
Let's look at Solana vs. L2s, and see why one might be preferred.

How do Solana CPIs work?
That is, how do Solana programs call into other Solana programs?
Here's a quick 6 tweet explanation 👇
1/ If you're unfamiliar with Solana transactions/instructions, you might want to take a look at this first.
There are three main reasons why people say Solana is centralized:
1. Expensive to run a validator 2. Token distribution 3. Only one blockchain software client
Let's take a look at each of these reasons 👇
1/ IMO it doesn't matter how much it costs to be a validator—it matters how many validators there actually are, and what the Nakamoto coefficient is.
Turns out Solana's Nakamoto coefficient is pretty high (19 validators required to halt the network).
Here's a diagram that shows all the different parts of a Solana transaction.
More details below 👇 1/ Each Solana transaction contains a message, and the first part of each message is its header.
The header is simple, it just contains the numbers described in the diagram.

1/ Here's a thread of all the Solana threads I've written (a thread of threads), plus some great threads/tweets by other folks. I'll try to keep adding onto this in the future.
First, 11 resources to get started with Solana development
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.

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

How do NFT whitelists work on Ethereum? It's pretty simple—let's take a look at the @smilesssvrs smart contract to see how they did it 👇
1/ The metadata of a Metaplex NFT is stored in a PDA account.
Each NFT is associated with a unique mint account. The metadata PDA is derived from the mint account's address + the metadata program's info.

PDAs, or program derived addresses, are one of the trickier #Solana concepts 🤔. 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 👇
1/ First of all, if you don't know how Solana's account model works, check out this thread. It's only 5 tweets!
How do #Solana tokens work? What are the Solana equivalents of ERC20 and ERC721? Let's find out 👇
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.
Proof of Stake is used by #Solana and Ethereum 2.0. But what is Proof of Stake, and how does it work? A short thread 👇
1/ "Proof of stake is a type of consensus mechanism used by blockchain networks to achieve distributed consensus."
In other words, Proof of Stake enables nodes in a blockchain network to agree on the state of the blockchain.

#Solana accounts explained in 5 tweets 👇
1/ There are 2 kinds of accounts in Solana.
Data accounts store data. Program accounts store executable programs.
Each account has an address (usually a public key) and an owner (address of a program account). There are a few more fields every account stores, see 👇

I'm currently learning how to program on @solana, and have found it much more difficult than learning to program on Ethereum.
Luckily, there are lots of great resources out there. Here are the ones I've found most helpful! 👇
1/ First, it's helpful to at least slightly understand Rust 🦀 before diving into Solana dev.
Luckily, there's a great free book about it!
You don't need to read the whole thing, just enough to get the syntax down. You can always refer back to it later.
