Deprecate String-Based Address Fields

THIS RELEASE IS BACKWARDS-COMPATIBLE WITH ALL PREVIOUS RELEASES.

This release deprecates all string-based Address fields and replaces them with AccountIdentifier-based fields. This empowers blockchains that support associating multiple keys with an account to provide expressive interaction using the Construction API.

Backwards Compatibility

When the AccountIdentifier-based fields are not populated, clients assume that the string-based Address field is equal to:

{
  "address": {{Address}},
}

Changelog

• Deprecate string-based Address Fields #48
