In this article we review NFT token architecture and metadata storage options. We show the main disadvantages and risks of the existing NFT architecture and infrastructure. NFT minting performance was analysed on various distributed ledger technologies. The main problem of NFT technology that we highlight is its associated metadata storage options. Since in-secure Web2 based servers are allowed as a storage solution data that is associated with the NFT tokens can be corrupted, modified and lost. Thus harming the end user. We see the main solution for such issues in data blockchains proliferation as they would provide data immutability.
