We aren’t getting involved with identity directly (yet) for various reasons. In fact, there are benefits to solving identity and the proof of claims as separate concerns. We are aware of the “volume” problem by only putting hashes on chain, along with a merkle tree approach for issuing to cohorts, which will drastically reduce the number of transactions. Of course, it’s early days and the purpose of this release is primarily to gain helpful feedback and criticisms to help inform the way forward. More to come soon!
