The RAG Wangiri Blockchain Consortium is an initiative led by RAG and Orillion Solutions which seeks to uses secure, cost-effective and accessible blockchain technology to pool industry intelligence about the numbers used to originate calls by wangiri ‘call back’ fraudsters.
In April 2019 the RAG Steering Committee approved a project for the development of a blockchain-based solution by Orillion Solutions that consortium members would be able to use for the creation of a global ledger of fraudulent numbering data. The first use case was agreed as being wangiri fraud. Wangiri affects customers of Communications Service Providers (CSPs) globally. In recent years there has been a significant increase in the number of wangiri warnings issued to consumers by regulators around the world.
The project is entering phase 2 of collaborative pilot development at the date of writing (19 September 2019). The pilot began in August 2019 and the first phase involved:
- agreeing terms with a limited number of telcos and vendors who became the first consortium members
- connecting the initial wave of consortium members and identifying any obstacles to connection
- rolling out basic functionality and receiving feedback
- experimenting with and adjusting the information collected by the ledger
Phase 2 will add additional features, extend the duration of the pilot until late 2019, and include a significantly increased number of consortium members. If successful, this pilot phase will be succeeded by transitioning to the ongoing operational model for this initiative.

History of the Wangiri Blockchain Pilot
The prototype solution was demonstrated at the RAG conferences in Bonn and Toronto during June 2019. A wide number of parties expressed interest in taking part in a proof of concept or pilot. The pilot would involve an agreed consortium of CSPs and other interested vendors being granted access to the blockchain solution, and creating a distributed ledger of wangiri numbering data, using their local wangiri blacklist data, which all members in the consortium would benefit from using during the pilot phase. The pilot phase started in August 2019.
Pilot Success Criteria
The pilot intends to achieve the following outcomes:
- Creation of a consortium of CSPs and vendors who would contribute collectively to the creation of a global ledger of wangiri fraud numbering information.
- Delivery of a workable blockchain solution by Orillion Solutions for the consortium members to use in creating the wangiri ledger.
- The design and agreement of an operating model by the pilot consortium members for the onboarding, use and maintenance of a distributed ledger in the implementation phase of the solution.
- The development of a single source of wangiri numbering data from individual consortium member contributions that demonstrates the incremental value of this collaboratively created master data source, relative to individual contributions in isolation.
- Real-time updates from a globally distributed consortium that supports improved detection and management time for wangiri fraud.
- Solution performance that adequately meets the needs of the consortium users.
- The ability to create a ranking mechanism/ruleset for consortium member contributors and wangiri numbers that helps to improve the level of trust in the data and solution itself.
- An agreed roadmap of solution features and prioritized future use cases for the RAG/Orillion blockchain solution.
Roles and Responsibilities
The successful implementation of the ledger will require a number of different stakeholders to support the planning, implementation and use of the solution.
The stakeholders and their responsibilities during the pilot are as follows:
- Participation in and approval of pilot planning activities.
- Receipt of consortium member requests for access to the blockchain technology.
- Review and approval of consortium member access requests.
- Issuing of digital certificates to approved consortium members.
- Oversight of the wangiri blockchain solution use, including intervention and de-authorization of solution access where consortium member abuse exists.
- Continued marketing support for the RAG Wangiri Blockchain Leger with industry and other interested parties.
- Development, testing and implementation of the RAG Wangiri Blockchain technology.
- Design and management of the pilot implementation plan with RAG and consortium members.
- Management and rectification of any blockchain technology related issues experienced during the pilot phase.
- Advice and support for RAG and consortium members to ensure a smooth pilot technology implementation and use.
- Development of the post-pilot case study for use by RAG in marketing and future phase motivation.
- Facilitating the collaboration between RAG and consortium members for the co-design of the future RAG blockchain solution feature and use case roadmap.
Pilot Consortium Members
- Participation in the pilot phase planning workshops and discussions to ensure readiness for the pilot phase.
- Management of implementation requirements within their respective consortium member organizations.
- Requesting access to the pilot blockchain technology using the agreed process.
- Contribution of known and suspected wangiri numbers to the RAG ledger, using historical and current wangiri blacklist information.
- Extraction, analysis and use of the global wangiri ledger data for use in active wangiri fraud risk management.
- Providing feedback to RAG and Orillion in relation to the implementation and use of the technology during the pilot that relates to the technology, local infrastructure requirements, ledger data, benefits of the pilot for their respective organizations and future blockchain features and use cases that would be beneficial to the consortium and industry.
Video Illustration of the Interface
The following video shows how users can add records to the ledger. They can key data for an individual wangiri call, key data for calls from a range of numbers, or load a batch file. The video also shows how data can be downloaded as a CSV file.
How to Obtain Access to the Ledger
Access to the ledger is free for authorized telcos and vendors. Interested parties may get in touch using the form below.
