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 breaks the "code is law"
contract that once a program is on-chain it is immutable. Because of this,
care should be taken before executing upgradeable programs which still have
a functioning authority. For more information refer to the
instruction
module.
The solana program deploy
CLI command uses 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.
