Frequently Asked Questions
Have questions? We have answers. Here are some common inquiries about implementing blockchain in finance.
Blockchain enhances security in several key ways. Its decentralized nature eliminates single points of failure, making it extremely difficult for hackers to compromise the entire system. Every transaction is cryptographically linked to the previous one, creating an immutable and tamper-proof ledger. This means that once a transaction is recorded, it cannot be altered or deleted, which drastically reduces the risk of fraud, both internal and external. Furthermore, transparency can be controlled through permissioned networks, ensuring only authorized parties can view or add data.
Absolutely. While early public blockchains were pseudonymous, modern enterprise blockchain solutions are designed with compliance at their core. We build permissioned blockchains where all participants are known and vetted. We integrate Decentralized Identity (DID) solutions to streamline KYC processes in a secure, user-controlled manner. Furthermore, we leverage AI on top of the blockchain ledger to perform real-time transaction monitoring for Anti-Money Laundering (AML) purposes, flagging suspicious activities far more effectively than traditional systems.
Blockchain drives cost savings by automating processes and eliminating intermediaries. For example, in cross-border payments, it bypasses the costly network of correspondent banks, reducing fees and settlement times. In trade finance, it digitizes paperwork and uses smart contracts to automate verification and settlement, cutting administrative overhead. By creating a single, shared source of truth, it also reduces the costs associated with reconciliation and dispute resolution between multiple parties.
A public blockchain (like Bitcoin or Ethereum) is open for anyone to join and participate. While highly decentralized, this is generally not suitable for banking due to privacy and compliance concerns. A private or permissioned blockchain (like Hyperledger Fabric) is an invitation-only network where participants are known and have defined roles and permissions. This model is ideal for the financial industry as it provides the security, immutability, and efficiency of blockchain while maintaining necessary privacy, control, and regulatory compliance.
The timeline varies depending on the complexity of the project. A Proof of Concept (PoC) to validate a specific use case can be developed in as little as 4-6 weeks. A Minimum Viable Product (MVP) for a solution like a simple remittance platform might take 3-5 months. A full-scale, enterprise-grade platform for asset tokenization or a DeFi protocol could take 6-12 months or more. Our process always starts with a detailed discovery phase to define a clear roadmap and provide you with a realistic timeline.
Data privacy is paramount in our designs. In permissioned blockchains, we use channels or private data collections to ensure that participants only see the information relevant to their transactions. For example, in a trade finance network, the buyer, seller, and their respective banks would be on a private channel, and the shipping company would not have access to the financial details. We also employ advanced cryptographic techniques like zero-knowledge proofs to allow for verification of data without revealing the underlying data itself.
