Suggested standard for transaction meta-data storage

[aufbakanleitung]

With the Nano community we've developed a standardised json format for storing transaction meta-data. This information is not only useful to a user for understanding their own transaction history, but it would also form the basis for important functions like calculating capital gains tax or leaving paper trails, which are directly relevant to business adoption. If all Nano wallets would adopt this format it would smooth the third party application development.

Kindly take a look at this example:
