Inscriptions are taking Solana by storm.

Drawing from Bitcoin's BRC-20 standard, SPL20 inscriptions enable the direct on-chain storage of digital art

Still don't understand what's going on? Don't worry, we've got you covered 👇🧵 SPL20 inscriptions are unique Solana addresses that contain images stored directly on the blockchain. This differs from regular NFTs that store their art on a third-party service like Arweave. Now, your images have their own address instead of an HTML link

NFT Compression is taking Solana by storm.

Top-tier teams like Crossmint, Dialect, Helium, and Drip Haus are utilizing it for novel crypto use-cases.

But how does compression work? What does it even mean?

A brief explainer 🧵 On Solana, on-chain storage is not cheap.

NFT Compression simply refers to the process of storing the bulk of NFT data (such as image URLs, traits, etc) off-chain instead of on-chain.

But, how can we do this while still remaining decentralized and secure?

Via Merkle Trees!

Accounts on Solana and how they differ from Ethereum — explained 🧵 Accounts are ubiquitous on Solana.

You may hear someone refer to their wallet as an account, you may see a developer refer to a program as an account, or you might read that an NFT is stored in a token account.

All are true.

In Solana, everything is an account.

Crash Course: Blocks, Slots, and Epochs on Solana 🧵 Solana's terminology is a bit overwhelming sometimes. What is a block, a slot, or an epoch? What are the differences between them?

In this thread, we'll explain everything.

Solana Transaction History Crash-course 🧵 When you make a transaction on Solana, you specify which accounts are involved in the transaction — state and data are decoupled.

Solana validators keep track of the signatures for these transactions in something called Blockstore (and generally BigTable for older records).

Solana RPC Crash-course 🧵 In Web2 dev, you interact with a myriad of APIs to get the data you need. You use Stripe for payments data, Plaid for banking data, Twilio for SMS data, and so on.

In crypto — all of the data is on-chain. To fetch it, you interface with the nodes participating in the network.
