Strictly speaking, representing an asset as a token on a distributed ledger equates to creating a title of ownership that, instead of being a paper with a signature, is instantiated as a smart contract on a distributed ledger. In effect, the token is a contract between the holder and the custodian of the asset, and it needs to have legal ground to be enforced.
From the point of view of asset managers, a tokenized asset is a virtual object that acts as a share in an underlying physical asset. On IdeaFeX, these tokenized assets are always fulfillable, physically delivered or otherwise. One can also consider the token as an investment instrument that is backed by physical wealth. For example, a copper mine can be tokenized, and the resulting tokens are shares of ownership in the copper mine. In comparison, most currencies of the world today are not backed by physical ownership of any underlying physical asset. For example, one cannot exchange a euro or dollar for a fixed amount of gold as it used to be the case.
