#### Heterogeneous key types cannot be aggregated
Only one type of signature can be aggregated and our legacy signing schemes
cannot be aggregated. In practice, this means that aggregated signatures can
be created over the set of all validators that use BLS signatures and validators
with alternative key types, such as Ed25519 must be included separately in
blocks and votes.
Aggregation requires a specific signature algorithm, and our legacy signing schemes
cannot be aggregated. In practice, this means that aggregated signatures could
be created for a subset of validators using BLS signatures, and validators
with other key types (such as Ed25519) would still have to be be separately
propagated in blocks and votes.
#### Many HSMs do not support aggregated signatures
