Identity reimagined for a user-centric web

IDX is a multi-platform identity protocol that replaces centralized user tables with a decentralized alternative. IDX allows users to build up a unified digital identity consisting of all their data while enabling developers to break down silos and freely share a users' data between applications.

Why IDX?
‍

Eliminate users from your server

Replace centralized user IDs and user tables with a secure decentralized alternative

Connect many accounts

Link multiple blockchain, web3, and social network accounts to the same user identity

Use any datastore

Store user and application data in any DB server, blockchain, or Web3 datastore

Make your data discoverable

Add references to your data to a user’s personal index, where it can be discovered by others

Import data from other apps

Discover a user's entire catalog of data by querying the index and import it into your app

Give users control

Give users control over data discovery, sharing, and permissions

How it works

Index

The index is a key-value store document that stores a list of

definition

record

mappings.

Every user has one global index and its entries represent the entire catalog of data that belongs to a user. An index is similar to a row in a user table.

{

'kjz123...456'

'ceramic://kjz975...531'

'kjz987...654'

'ceramic://kjz135...579'

'kjz678...132'

'ceramic://kjz426...846'

'kjz234...678'

'ceramic://kjz531...135'

'kjz654...321'

'ceramic://kjz753...194'

'kjz963...135'

'ceramic://kjz824...702'

}

Every identity begins pseudonymously as an empty index. As records are added to the index, the identity gets stronger and gains meaning.

Records

Records are documents that store discrete units of identity information for a user. They can store content and/or foreign key references to external datastores. A record is similar to a cell in a user table. The

recordURL

is a value in the

index

{

'name'

'Satoshi Nakamoto'

'description'

'I make magic internet money.'

'image'

'ipfs://QmUugcA3UBnX8rUhNo7q59SyxwqqxYLjvhf1qRNUUQbsGn'

'emoji'

'👍'

}

]

An identity is a collection of records.

Definitions

Definitions are documents that describe records with metadata and a schema. Definitions allow records to be discovered and queried using metadata and are similar to a column in a user table. The

definitionID

is a key in the

index

{

'name'

'Basic profile'

'description'

'A simple user profile'

'schema'

'ceramic://kjz987...654'

}

{

'name'

'Blog posts'

'description'

'A list of blog posts'

'schema'

'ceramic://kjz528...369'

}

{

'name'

'Crypto accounts'

'description'

'A list of crypto accounts and proofs'

'schema'

'ceramic://kjz683...971'

}

{

'name'

'Follows'

'description'

'A list of users you follow'

'schema'

'ceramic://kjz227...058'

}
