Description

Iroha 1 provides an easy way to store metadata in user account. This feature was super useful to use Iroha as a data ledger rather than just using fungible assets.

Iroha 2 seems to keep this super feature and even extends it with metadata and store assets (https://hyperledger.github.io/iroha-2-docs/guide/configure/metadata-and-store-assets.html).

Your suggestions

Could you provide a more detailed documentation (especially client usage in rust and with the bash client if it's implemented yet) about how practically using metadata and store assets for iroha 2 ?

Who can help?

No response

This feature was super useful for using Iroha as a data ledger rather than just using fungible assets.

Well, let's imagine its internal behaviour. Both Store and metadata would have separate records in the blockchain for every update. Given that, you can only get more fields than you need with Metadata.

In that case, does it mean only a question of API usability remains here?

[v-a-net]

I think so! From my understanding of the current implementation, I think that the tutorial documentation mainly lacks practical details and examples about this topic. This was the main reason of this issue.
