Understanding Program Derived Addresses: The Solana Address That Has No Private Key

Solana programs can use Program Derived Addresses (PDAs) to generate deterministic addresses for user data, eliminating the need for lookup tables. PDAs are 32-byte addresses derived from a program ID and seeds, such as a user's public key. This allows programs to find user data without storing a mapping table. With Anchor, PDAs can be derived automatically from the IDL.
