Metahub is a Blockberry Name Service much broader than some domain name services. It includes a variety of on-chain and off-chain data, carefully collected from numerous services and organized (both manually and autonomously) for easy use.

Let's look closely at how it works and what data is being collected.

Collected Metadata

Different chains have their domain model. Things get even more complicated when connecting off-chain data.

Metahub, as part of the platform, aims to aggregate more particular valuable data pieces, standardize the approach, and thus make data easy to use and accessible.

On-chain Metadata

We aggregate metadata on the blockchain in Metahub for later use and faster recall.

Off-chain Metadata

Off-chain data is no less valuable. They are as diverse as possible and also have a large number of sources. We are constantly looking for new partners and suppliers of such data, aggregate them, and provide them for easy use.

Data Types	Details
User/manual input metadata	Metadata collected by the Blockberry content management team, user submissions

Following this link, you can find the metadata specifications for the data manually submitted to the platform and processed by our content management team.
