I've spent a lot of time doing consulting around blockchains for fortune 500 companies. Most technology choices are not a need. You can use MongoDB or MySQL in most cases. There are places where MongoDB has benefits, just as there are cases where a permissioned, immutable record has benefits. It's not a silver bullet, but it can add trust. This article seems to miss that creating immutable records of intermediary attestations can serve as an audit trail later. If these audit logs are 100% immutable, that's nice. It's more evolutionary than revolutionary, but it still has some value.
