Learning path
Understand Solana accounts and instructions
Identify program ownership, transaction boundaries and the role of ordering evidence.
For a hypothetical profile edit, identify the data account, owner program and required signer. Explain what a transaction rollback can undo, and which website actions fall outside it.
