The rapid growth of the RAG Wangiri Blockchain, a consortium where telcos use a distributed ledger to exchange intelligence about wangiri fraud, has led to the redevelopment of its technology core by SORAMITSU
, expert developers of permissioned blockchains. Based in Tokyo and Zug, SORAMITSU are the authors of Hyperledger Iroha
, a form of blockchain that only allows data to be shared with peers under specified conditions, making it ideal for solutions that rely on controlled access to sensitive data. The new core has simultaneously been redesigned to permit the exchange of data concerning an expanding range of frauds, leading the service to be renamed the RAG Fraud Blockchain.
SORAMITSU has partnered with the Risk & Assurance Group (RAG)
and Orillion Solutions
, the original developers of the RAG Wangiri Blockchain, by taking a stake in a new joint venture company that owns the rights to the technology created for the consortium. This next-generation blockchain ledger will lever SORAMITSU's expertise in delivering solutions that require real-time updates, unimpeachable trust, and the use of tokens to earn and buy rights within the blockchain ecosystem. This will further RAG's vision of creating a fraud intelligence exchange where telcos that actively contribute their data will earn the right for continued free access, whilst other firms and organizations including software vendors and law enforcement agencies may pay for access or else be granted visibility of strictly limited subsets of the common ledger.
SORAMITSU has considerable experience of developing secure and scalable blockchain-based solutions for the electronic communications and financial sectors. In 2018 they were selected by the National Bank of Cambodia to provide the core for Bakong, the world's first blockchain-based, central-bank-operated national payment infrastructure. Bakong has run successfully with real money and no security issues since 2019, prompting SORAMITSU's recognition with a FinTech & RegTech Global Award in 2020 and a Japan Financial Innovation Award in 2021. Other SORAMITSU collaborations involve the authentication and settlement of transactions with commercial banks, universities and securities depositories in Indonesia, Slovenia, Japan and Russia as well as providing the technology for decentralized peer-to-peer financial transactions on both Android and iOS mobile phones.
The following aspects of Hyperledger Iroha make it ideal for the RAG Fraud Blockchain.
- Security and resilience: Iroha has been audited by Nettitude and stress-tested as a component of system-critical financial infrastructure. Its Byzantine fault tolerant consensus mechanism ensures that data will remain secure even if multiple nodes are compromised by accidents or bad actors.
- Computational efficiency and scalability: Iroha's approach to blockchain is straightforward: be a blockchain, not an operating system. Its parsimonious architecture offers high speed, throughput, and scalability without a loss of functionality or security. This is crucial given the volume of data that a worldwide anti-fraud consortium can expect to generate and process.
- Flexibility and user-centricity: Iroha's roles-based permission system will expedite services and functions tailored to multiple stakeholder groups: multinationals, wholesale carriers, retail service providers, regulators, LEAs, IGOs, NGOs, etc.
- Modularity and extensibility: Iroha is an open-source contribution to the Hyperledger project, which means that user data will never be locked in with a single technology provider. A simple command line interface offers a low barrier to entry, while SDKs in multiple languages provide complex development options for experienced users. Iroha v2 incorporates a new smart contract layer, enabling conditional functions to be designed in response to consortium member needs.
The migration to the new core also opens the door to important new features.
- Development of the event record tokenization scheme to enable fair and reliable incentivisation of peer contributions.
- Debut of a redesigned user interface and a front-end enriched with new analytics and data visualizations.
The Hyperledger Project has much in common with RAG's anti-fraud initiative: both are community-led initiatives which synergize the practical knowledge of many professionals dedicated to making technology work for the common good. SORAMITSU contributed Hyperledger Iroha to the public out of a commitment to this vision, and has taken the lead in maintaining it out of confidence that the quality of their efforts will attract the right kind of business partners. The work of the business partners confirms SORAMITSU shares RAG's passion for cooperation, creativity, and technical precision.
