GAIN is a shared vision for an interoperable global identity network to bridge existing "islands of trust". It emerged from a need to address issues like financial crime, misinformation, and privacy concerns resulting from increased anonymity and lack of control online. GAIN is guided by 5 non-profits and aims to be global in scale, technology agnostic, and built upon open standards. Its Proof of Concept community group is currently connecting identity providers and relying parties from different jurisdictions to test GAIN's technical hypotheses, such as supporting diverse identity architectures and cross-border participation, through 2022.
2. GAIN emerged from something you know
In the beginning, there was trust
on the internet
But as it opened up,
trust was lost.
3. GAIN emerged from something you know
Weaponized Anonymity for Some
Financial Crime is up to 5% of GDP (2Tn USD)
Misinformation
Lack of Control for the Rest
Pervasive Tracking
Identity Theft
4. GAIN is a shared vision
Interoperability
Trusted Network
An interoperable system that bridges islands of trust

5. GAIN became a white paper

9. GAIN POC Community Group
GAIN can be built on top of existing networks and solutions
IIPs from different jurisdictions can input to GAIN
The network can support different IIP architectural approaches (federated,
SSI, etc.) and different interoperable interfaces to RPs (OIDC, DIDCom,
WACI, etc.)
IIPs can offer a variety of APIs built to serve different purposes into the
network
RPs can access assured identity data from IIPs in a simple and trusted
approach (single contract, single credential and a single technical
specification)
The GAIN POC Community Group is a test bed for
GAINs technical hypotheses
Success Means:
At the end of the POC,
Any party will be able to understand
what they need to do in order to
implement (technically) in a live
environment
We will feel successful if participants (or
others) want to take it to the next level

Q3/2021
Started Alpha PoC
Q4/2021
Successful conformance tests of
the first group of IDPs
Q1 2022
Connect RPs via standardized APIs and
network functions

Establish OIDF community group
Agree on goals and hypothesis to test
Demonstrate end2end

14. Hypothesis 5 Simple RP Integration
Vision: Register Once, become a client to all the IDPs.
Trusted RP management to allow RP to access all IDPs with single credential
Trusted IDP management to allow RPs to find and select suitable IDPs
Approach
Collection of Requirements
Survey of design choices (DNS-based, OpenID Connect Federation, EU Trusted List, )
Selection and setup of test network
Assumption: there can be multiple GAIN-based networks, such networks might be federated
15. Hypothesis 5 Simple RP Integration
Use cases to evaluate hypothesis
Electronic Signing
Identification of Domain Registrants
Provisioning of SSI Credentials
Remote Staff Onboarding
Students Identification
User Account verification (e.g. Twitter)
Account Recovery
Age verification

Editor's Notes
#5: Trust layers already exist on the internet. The GAIN vision is that we connect them. That we create a globally interoperable network of networks that leverages the high trust data that exists in trust networks and trusted institutions today - and also interoperates with the emerging decentralized solutions, SSI and wallet providers etc.
#6: As everything must, GAIN became a white paper.
We had technologists, lawyers, leaders in existing federated identity networks. SSI and thought leaders in decentralized identity. Wallet creators. Identity information providers. Verifiers and business leaders who see the value in the network.
We did not agree on everything even the papers target audience. But we shared that vision for global interoperability and its potential to
#7: We see non-profits and standard-setting bodies continuing to guide the GAIN vision though we invite others to participate
#8: reach is key success factor in identity
solving the identity challenge on a global level requires a global solution
building from scratch is very hard
leveraging local solutions into a global network is the pragmatic solution
