What is a Unique Program Id

The instruction's program id specifies which program will process this instruction. The program's account's owner specifies which loader should be used to load and execute the program and the data contains information about how the runtime should execute the program.

In the case of on-chain BPF programs, the owner is the BPF Loader and the account data holds the BPF bytecode. Program accounts are permanently marked as executable by the loader once they are successfully deployed. The runtime will reject transactions that specify programs that are not executable.

Unlike on-chain programs, Native Programs are handled differently in that they are built directly into the Solana runtime.[1]
