ERC1155

Multi-Token Standard (1)

The ERC-1155 standard relates to a smart contract interface that can represent any number of fungible and non-fungible token types. Existing standards such as ERC-20 require the deployment of separate contracts per token type. The ERC-721 standard’s token ID is a single non-fungible index, and the group of these non-fungibles is deployed as a single contract with settings for the entire collection. In contrast, the ERC-1155 Multi Token Standard allows for each token ID to represent a new configurable token type, which may have its own metadata, supply, and other attributes.

Why use multi-token standards?

The primary reason that HydroLink utilises a multi-token structure is that it allows us to have a fungible and non-fungible component.

NFT Component:

Data that is stored in a certificate is often obtained from a specific generation device. Additionally, the time of certificate issuance results in unique attributes. It follows that there cannot be two certificates from the same device and the same time frame.

Fungible Component:

The hydrogen that the certificate represents is just a commodity, homogenous and exchangeable. Note: assume hydrogen classification is consistent

Certificate Structure and Behaviour:

Certificates in Origin are therefore non-fungible tokens, in which all the unique device information is stored, combined with the energy volume that is implemented as several fungible tokens. Every fungible energy token is therefore immutably tied to the certificate that holds all the information about the origin of this electricity but is itself interchangeable.
