Get Chain Tips

This endpoint retrieves information about all known tips in the block tree.

The possible values for status:

1. invalid: This branch contains at least one invalid block.

2. headers-only: Not all blocks for this branch are available, but the headers are valid.

3. valid-headers: All blocks are available for this branch, but they were never fully validated.

4. valid-fork: This branch is not part of the active chain, but is fully validated.

5. active: This is the tip of the active main chain, which is certainly valid.
