TL;DR
Migrate the Address Lookup Table program to Core BPF.
Summary
Migrate the Address Lookup Table program to Core BPF.
Motivation
BPF programs offer less complexity than native programs for other clients, such as Firedancer, since developers will no longer have to keep up with program changes in their runtime implementations. Instead, the program can just be updated once. In this spirit, Address Lookup Table should be migrated to Core BPF.
Impact
Validator client teams are no longer required to implement and maintain the Address Lookup Table program within their runtime. All validator client teams can work to maintain the single Address Lookup Table program together.
Backwards Compatibility
The Core BPF implementation is 100% backwards compatible with the original builtin implementation.
Security Considerations
The program's reimplementation poses no new security considerations compared to the original builtin version. The greatest security concern is a mistake in the reimplementation.
