Project Context:
Today on the current used Internet model, we are massively overloaded by Data Asset we don't know where they come from, if we can trust the source and if we can trust the integrity ot the data.
The future Web version will be a web of trust, where information will have proof of source authenticity, proof of integrity of the information itself, will be open and available for all at world scale, will be easily understood by machine (Semantic Web Envelop needed around Bruto Data Asset). We will see a new area where Data Asset will be exchanged between Data Asset Producers and Consumers with a very high level of quality and trust enabling new world wilde decentralized trusted quality business model, enabling to solve the biggest problems on the planet, like helping on climate change, improving research on disease...
In order to deliver that promise we will need to have the following building blocks:
- Big Open Data: to produce and share large amount of open Data Asset available to all
- Semantic Web envelopp on all assets: to enable easy understanding of the Data Asset by all machines and enable easy world wide interoperability on them
- Ledger Technology: to deliver trusted anchors for the Open Data, enabling Data Producers and Consumers to exchange and consume Open Data on a trusted way, without any central authority or censhorship entities
- AI: To run "Solving Problem" algorithm on trusted Open Data and delivering Trusted Solutions
Project Scope:
The purpose of this project is to deliver a Trusted Anchor Registry for Open Data available at World Scale. This registry will be used by Open Data Producers to anchor for each Open Data Asset they produce, proof of Source authenticity (provenance) and proof of Data Integrity, plus specify the conditions under which the data can be consumed (the contractual agreement). Each Open Data Asset will catch in his Semantic Web Envelop a link to that Open Data Trusted Anchor registry where the Source Authenticity, the Data Integrity and consuming contractual agreeement is stored. Data Consumer will consume the Trusted Open Data and will be able to validate the Meta Data Trust information present on the semanic Web envelop of the Trusted Data and will query the Open Data Trusted Anchors SmartContract to verify the Proof of Source Authenticity, the Proof of Integrity, and the proof of the contractual agreement of published data, plus will be able to see if they have access.
Consumer Business Cases would be:
Trustworthy Open Data coming from the Health Sector for disease research (like cancer, Covid19 Analytics...) Trustworthy Open Data coming from the world climate parameter (CO2 level, Temperature...) Trustworthy Open Data coming from green energy (to monitor the growing adoption of green energy on the different regions of the world and show compliancy with) Trustworthy Open Data coming from academical research.
User Stories:
Story 1: In order to deliver a "Proof of Source Authenticity" on a Data Asset I have produced, as a Data Producer Entity, I publish on the ODTA Registry the Proof of Source Authenticity of the Data Asset.
Story 2: In order to deliver a "Proof of Integrity" on a Data Asset I have produced, as a Data Producer entity, I publish on the ODTA Registry the Proof of Integrity of the Data Asset.
Story 3: In order to publish "Use and Processing Terms and conditions" on a Data Asset I have produced, as a Data Producer Entity, I publish on the ODTA Registry the Proof of the Integrity of the "Use and Processing" Terms and conditions contract.
Story 4: In order to setup the "Data Access Conditions" on a Data Asset I have produced, as a Data Producer, I publish on the ODTA Registry the "Data Access Conditions" to setup the access control on the published Data
Story 5: In order to validate the "authenticity of the source" that produce the Data Asset I receive, as a Data Consumer Entity, I query the ODTA Registry to validate the authenticity of the Data Asset source.
Story 6: In order to validate the "integrity of the Data Asset" I receive, as a Data Consumer Entity, I query the ODTA Registry to validate the authenticity of the Data Asset.
Story 7: In order to validate the "Use and Processing Terms and conditions" to the Open Data Asset (present in the Semantic Web Envelop Received), as a Data Consumer Entity, I query the ODTA Registry to validate the Integrity of the "Use and Processing Terms and conditions" to the Data Asset (Free or specific Access Cost conditions, intellectual property rights...)
Story 8: In order to "give access to a paid-access Data Asset" I produce to a specific Data Consumer, as a Data Producer Entity, I give the access to the Data Asset to the Data Consumer
Story 9: In order to "get access to a paid-access Data Asset" I received, as a Data Consumer Entity, I paid the fee to get access to the Data (Not yet implemented in this version.01)
Key Concept Definition:
- Proof of Authenticity: Signature done by a Data Publisher + Public key to verify it
- Proof of Integrity: Hash of the Data (including the Semantic web envelop)
- Use Terms and conditions: describe the authorized exploitation of the produced Data Asset, the intellectual property conditions on it, free or need to pay for access...
- Processing Terms and conditions: what a consumer can do with it: read only (not copy authorized), copy, free or pay before access
- Data Access Conditions: mechanisms put in place to protect special access to Data Asset, like paid-access.
The ODTA Registry version 0.1 will be composed of 3 Smart Contracts:
- ODTA Validator Smart Contract -> Main SC logic
- ODTA Storage Smart Contract -> Diamond Storage Illustration
- ODTA Proxy Smart Contract -> recommand to use Open Zepplin SC (out of scope of this first version of the project)
- Gnosis Multi-Sig Smart Contract -> reuse Gnosis Multi-Sig Wallet for operator of SC
In order to have better readability a special githbook has been done for this project to illustrate the following:
- Design of the Data Model
- Design explanation of the SmartContract
- Smart Contract Method Signature
- How to install and use this Gith project and how to setup the demonstrator + illustrative youtube video of ODTA
