Of course in the beginning we will have only ed25519 signatures by default. However, in future it will be simple to switch between different DSA algorithms (for example when we need to support HSM with non-ed25519 crypto) if we start implementing multihash approach now.
Proposal 3. Do not store

public keys in the configs
Actually all we need to obtain the public key is the private key. Also private key stored using multihash approach can be used to understand which DSA was used to produce the key.
