Within the blockchain, a regular DOT will only have one Uniform Resource Identifier (URI) link to Arweave. Using a regular DOT, an artist would store their digital artwork within Arweave. There is a limitation on how much information can be provided within a regular DOT, due to how its programmed.
For DOTs, we can include multiple information within the single URI link (i.e. contract, reports, image, etc.), thus making our DOTs more robust in capturing relevant information of the collectible items.
