Overview

The Previous Protocol is a blockchain protocol designed to support a new generation of NFTs and their associated metadata. It operates with a set of core contracts that manage different aspects of the protocol: Kind Registry, Set Registry, Relation Registry, and Token Registry. These contracts ensure the efficient and secure registration, management, and interaction of various protocol elements.

Kind Registry​

The Kind Registry contract is central to the Previous Protocol, managing the registration of “kinds,” which define the types and structures of objects within the protocol. Each kind specifies the attributes and behaviors that objects of that kind possess. This registry ensures that all kinds are uniquely identifiable and their definitions are consistent across the network. Registration of a new kind must be validated to ensure it adheres to protocol standards.

Set Registry​

The Set Registry manages the registration and organization of sets. Sets in the Previous Protocol are equivalent to NFT contracts in other systems. They group objects (NFTs) that share similar characteristics or belong to a specific collection. The Set Registry allows for the creation, updating, and querying of these sets, providing a structured way to manage collections of objects within the protocol.

Relation Registry​

The Relation Registry is designed to manage the relationships between different objects, sets, and kinds. It allows for the definition of relationships that specify how entities within the protocol interact with each other. This registry supports complex relational mappings, ensuring that all interactions are valid and adhere to the defined rules of the protocol. Relationships can include ownership, dependencies, or hierarchical structures.

Token Registry​

The Token Registry is responsible for managing fungible and non-fungible tokens within the Previous Protocol. It supports the registration of tokens, tracking their issuance, and ensuring that they comply with the protocol’s standards. The Token Registry facilitates the seamless integration and interaction of tokens with other elements of the protocol, such as sets and kinds.
