Arc 2 of 100 Days of Solana was about learning to read from the blockchain.
In Arc 1, we created wallets, worked with addresses, got devnet SOL, and started building the basic identity layer we need to interact with Solana. Arc 2 shifted the focus from identity to information.
What can you read from Solana? How do you ask for it? What comes back? And how is that different from fetching data from a normal Web2 API or querying a database?
The whole arc hangs off one useful mental model:
Solana is a massive public database where every table is readable and every query is free.
