# How are the asset named?

## Why?

Using an asset identifier, its secure as it's unique, but it's not memorable, so it was used a similar principle to the DNS to create an ANS (Asset Name System)\
We develop an external actor which reads over the blockchain data and provides a simple API\
For each Fixed Payout asset the pre-image of the asset identifier is taken from the message body.

## How?

Asset: "00000000a16a47c2640e5a3b40a50cbbaca19ac6c9a57666cf1d298c1ddf0049469a05a17b1077bde2c9548c651675353a320690f54c9d30e9797edd25e4fdcb2c351d09"\
has a long name GOOGL240122Bear261500 and a short name GOOGLBear261500.

The addressDB allows us to request the mint information of an asset by using \
`/addressdb/contract/mint :`
