What I learned about PDAs in a week of building on Solana -Hala Kabir
Article summary
Quick briefing — cleaned from the original RSS feed
On Solana, smart contracts (programs) are completely stateless logic engines. Unlike Web2 backends where a server holds context or modifies its own memory, a Solana program cannot store a single byte of data inside itself. If your program needs to remember an execution state—like a user's transaction count, a game state, or a global configuration—it must live in a completely separate account. Program Derived Addresses (PDAs) are the ultimate solution to this architectural requirement, providing…
