Frequently Asked Questions
Clear answers to common questions about building and implementing digital currencies.
What is the core difference between a CBDC and a stablecoin?
A CBDC is a direct liability of a central bank, representing a digital form of a country's fiat currency. A stablecoin is a liability of a private entity, which aims to maintain a stable value by holding reserves of assets like fiat currency or commodities. Essentially, a CBDC is sovereign digital money, while a stablecoin is privately issued digital money.
Which is better: a DLT-based or a conventional ledger system?
The choice depends on the specific policy goals. DLT-based systems (blockchain) can offer enhanced transparency, resilience, and programmability, which is ideal for fostering innovation and interoperability. Conventional ledger systems can offer higher raw throughput and may be simpler to integrate with existing infrastructure. We help you analyze these trade-offs to select the architecture that best fits your objectives.
How do you ensure the security of a national digital currency?
Our security strategy is multi-faceted. It includes using advanced, tamper-proof cryptography, designing a resilient and decentralized infrastructure to prevent single points of failure, implementing continuous AI-powered monitoring to detect threats in real-time, and conducting regular, exhaustive security audits and penetration tests by independent third parties. We also advise on future-proofing against threats like quantum computing.
Can your platform handle offline transactions?
Yes. We have developed and can implement secure protocols for offline payments, which are crucial for financial inclusion in areas with limited or no internet connectivity. These solutions typically involve secure hardware elements (like on a smart card or in a phone's secure enclave) to store and transfer value, with transactions being settled on the main ledger once a device reconnects to the network.
How do you address data privacy concerns?
We prioritize privacy by design. Our solutions can incorporate privacy-enhancing technologies (PETs) like zero-knowledge proofs and integrate with Self-Sovereign Identity (SSI) frameworks. This allows for a tiered approach to privacy, enabling compliant transaction monitoring by authorized entities while protecting the personal data of end-users from public exposure or unauthorized access.
What is the typical timeline for a CBDC pilot project?
While timelines vary based on complexity and scope, a typical pilot project follows a phased approach. The initial discovery and design phase can take 2-3 months. The core platform development and testing for the pilot can take another 6-9 months. The pilot itself, including deployment and data gathering, usually runs for 6-12 months. We work with you to create a detailed, realistic timeline tailored to your specific project.
