Identity Registrar is a module within the KIRA network that allows users to prove statements about themselves or others on the blockchain. These statements, known as claims, can be about anything the user wants to prove ownership of, such as a website, social media handle, or even a public IP address. The proof of these claims can either be a self-evident signature, or a social consensus of other KIRA accounts that have verified the claims. This enables users to build trust within their social circle without relying on a centralized authority to verify the claims.

One unique aspect of the Identity Registrar is that it is a simple, public key-value pair dictionary, also known as an associative array. This means that users can create their own entries and associate them with any value they choose. For example, a user could create an entry called "website" and associate it with the value "example.com" to prove ownership of that website. Every existing KIRA account is able to create an unlimited number of these entries, and each entry can be individually verified by any other KIRA account. However, if a verified entry is edited, all related verifications of that claim become invalid.

It is worth noting that users may not always want to reveal certain information to third parties in order to support their on-chain statements. In these cases, users can rely on other trusted KIRA account holders to validate their claims, creating a more convincing social proof without having to reveal private information to centralized entities that could potentially misuse or expose it. For instance, a Validator or other publicly known and respected actor can support the claim that a specific account is also a trusted party without requiring the account to reveal its private information.

The process of verifying an identity record involves a few steps:

It is important to note that verification requests must include a tip, which cannot be less than the min_identity_approval_tip network property (default: 2x the transaction cost of the approval/rejection transaction). This tip is meant to incentivize other accounts to verify identity records, or at least provide them with a refund of the transaction cost. Tips are paid regardless of whether the records are rejected or approved, ensuring that approvers are honest and trusted, rather than motivated solely by financial gain. The network governance can also choose to distrust any account at any time through a proposal process, marking them as potentially malicious and referencing the evidence.

KIRA offers a range of dedicated identity keys to make interactions with the network more user-friendly. These keys can be used to store various user-related information that can be interpreted by wallets, explorers, visualizers and other front-end applications. For example, instead of sending assets to a KIRA address, users can send assets by simply providing a username. This is possible because the KIRA network's governance can enforce certain key-value pairs to remain globally unique by modifying the unique_identity_keys network property. For instance, the moniker and username keys remain globally unique by default.

A consensus node can create one or more of the following keys in the Identity Registrar to increase its public recognition and trust

Users can create one or several of the following keys in the Identity Registrar in order to make their account easier to identify and recognize by other users.
