Expand description

An upgradeable BPF loader native program.

The upgradeable BPF loader is responsible for deploying, upgrading, and executing BPF programs. The upgradeable loader allows a program’s authority to update the program at any time. This ability break’s the “code is law” contract the usually enforces the policy that once a program is on-chain it becomes immutable. Because of this, care should be taken before executing upgradeable programs which still have a functioning authority. For more information refer to the loader_upgradeable_instruction module.

The solana deploy and solana program deploy CLI commands use the upgradeable BPF loader. Calling solana program deploy --final deploys a program that cannot be upgraded, but it does so by revoking the authority to upgrade, not by using the non-upgradeable loader.
