Arc 1 Recap: Keypairs, Wallets, and Solana Fundamentals
Arc 1 of the 100 Days of Solana initiative focused on the foundational concepts of Web3 development, particularly in the context of Solana. It emphasized the importance of keypairs in establishing identity, where a keypair is generated locally without the need for a centralized account creation process. The article also discussed the distinction between a Solana address and an on-chain account, highlighting how the address can exist independently of any stored data on the network.
- ▪Web3 development poses different foundational questions compared to traditional Web2 development.
- ▪A Solana keypair is created on the user's computer, consisting of a public key and a private key.
- ▪The public key serves as the Solana address, while the private key is kept secret to prove ownership.

How am I going to handle user accounts and auth? Where am I going to host this thing? Web3 development has its own set of "how do I start?" questions but they're not the same as what you'd expect if you're…
