BLOCKCHAIN – Reinventing Banking

Reported by: |Updated: March 13, 2020

One of the most discussed topics in the financial services industry today is blockchain. When it becomes a fully mature technology, it is expected that banks will be able to process payments almost real time, absolutely accurately and reduce transaction processing costs. It has been found that the technology can keep track of transactions, track ownership, become a reliable and tamper-proof source of information about almost any type of property, create smart contracts and when combined with open banking, lead to faster, automated lending decisions in a marketplace, promote and facilitate financial inclusion in a more efficient manner and control and eliminate frauds. However, what we today know about blockchain is very limited compared to the scope it has, especially in areas other than banking, like in regulation, privacy, data protection etc.
For banks to be making use of its true potential, there is need to build a right infrastructure – a truly global infrastructure – and a rugged network. More than this, there is the vital requirement for all the stakeholders to define and establish rules of engagement.
“One of the most talked-about topics in the financial services industry today is blockchain banking and when fully adopted, it will enable banks to process payments more quickly and more accurately while reducing transaction processing costs,” says Sunita Handa, Chief General Manager (IT – Channels & Operations), State Bank of India. “However, to capitalize on this potential, banks need to build the infrastructure required to create and operate a truly global network using solutions based on this transformative technology,” she adds.
She elaborates: “It is believed that as real time, open source and trusted platforms that securely transmit data and value, blockchain can help banks not only reduce the cost of processing transactions, but also create new products and services that can generate new revenue streams. The biggest key to turning blockchain’s potential into reality is a collaborative effort among banks to create the network necessary to support global payments. Banks need to look at the bigger picture and work together and with non-banks to help define the backbone that can underpin a universally accepted, ubiquitous global payment system that can transform how banks execute transactions. In other words, ‘The technology will only work if everyone adopts it. It has to be all or nothing’.”


Sunita Handa points out that in blockchain environment there may not be need of correspondent banks and hence the communication will be faster

Blockchain technology will have a direct impact on reducing operational costs and improving efficiencies by reducing manual processes and friction in day-to-day trade finance, digital identities and cross-border payments, emphasizes Monish Shah, partner, Deloitte Touche Tohmatsu India. It also enables a move away from paper-based to blockchain-stored transaction records, which can facilitate expansion to underserved markets such as small and medium enterprises while transforming online and international payments processes, he points out adding: “Its distributed ledger technology, smart contracts, security, built-in governance and control capabilities give institutions real-time access to trade finance data and information. This helps mitigate risk, eliminate wait time and increase transparency. For example, the main pain point in trade finance is ensuring authenticity of documents like letters of credit. By using blockchain, the process not only goes digital, but cross border payments also have a lower probability of getting halted due to authenticity issues.”
He is of the view that Indian Banks should consider making the switch to blockchain to remain competitive and keep future ready. “With an increasing number of fintechs entering this space, it is more important than ever for banks to continue to innovate and adopt new technologies. Banks can also alternatively look at partnering with established blockchain fintechs to collaborate through a win-win partnership,” says he.
Shah is confident that blockchain will also lead to digitization of banking processes, automated reconciliation and near real-time processing, instead of current batch-level processing. The technology also ensures authenticity through hash encryptions and mining, which significantly reduces risks and increases process controls.
Asit Oberoi, senior group president & global head, Transaction Banking Group at Yes Bank, points out that a significant portion of a bank’s costs is utilized in building the risk control infrastructure, which requires validation and verification of records, record keeping, non-repudiation and traceability. “With the adoption of blockchain, bank’s dependency for risk control on physical infrastructure and manual intervention will reduce,” says he.

He explains that blockchain being one of the most advanced technologies, offers complete automation of workflows as per every bank’s internal requirement. This ensures that irrespective of the size and nature of the bank, there is a way to implement blockchain based services that require minimal effort and investments. These changes in operating models and infrastructure deployments greatly reduces the operating cost for the bank, which may be better utilized for further enhancing business and increasing efficiencies, he says.
“Even in the case of CP issuance over blockchain, we have observed that the solution provided a seamless workflow for the users at the client’s end by automating their day to day manual operations carried out over email and phone to raise and track CP issuances. Apart from this, by having a robust system, we as an IPA have moved to a paperless flow eliminating the need for the issuer to go to a bank branch and submit the documents for processing. Instead of the earlier 2-3 days process, now the experience has been reduced to near real time for the customer. Therefore, there is considerable increase in productivity and revenue optimization at both the bank’s and the client’s ends,” he adds.
Asit Oberoi recounts how Yes Bank for the first time in Asia facilitated digital issue of commercial paper (CP) using blockchain technology with the bank acting as an issuing and paying agent for Vedanta, a natural resource conglomerate. He says market interest or penetration of the technology can be evaluated basis the interest among regulators, participants in the ecosystem and the value this technology brings in from an end customer experience.
Oberoi lists the advantages banks will have while using blockchain:
Reduced Turn-around-Time for transactions: Traditionally, financial transactions involved intermediaries like payment gateways, stock exchanges or clearing houses for completion and settlement. The involvement of multiple stakeholders increases the timeframe required for the transaction. Blockchain reduces the time taken to process a transaction.
Transparency: Blockchain shared ledger will enable parties involved to trace the transaction and its audit trails on a real-time basis. Non-repudiation and end to end traceability are key attributes that acts as enablers for banks to implement solutions on blockchain technology.
Reduced operational cost as well as increased productivity: Blockchain has the potential to reduce the involvement of intermediaries, bring in effective risk controls and reduce paperwork. These will further pull down the operational cost of the banks.
Enhanced end client service experience: Clients reap the benefit through improved TAT in end to end business processes with their bankers, since banking activities for the client are taken care through automated and digital workflows on blockchain.
Oberoi points out to the launch of Vajra, NPCI’s blockchain-based platform for interbank reconciliation and settlement, and firmly believes such initiatives from the regulators also provide a boost to the banks to explore more possible use cases. “It is only a matter of time when blockchain will translate into a norm compelling every one of the banks to come onboard. To be in line with this expected norm, banks need to start investing now to ensure they do not miss out on the next wave, which is around the corner,” advises.


Sunita Handa says operational costs, efficiency and security of a transaction are inversely proportional to the number of intermediaries or hops a transaction goes through. “Since blockchain technology is meant for dis-intermediation and direct visibility for the stake-holders, its appropriate use will definitely enhance efficiency and security and reduce the operational costs. Blockchain is a digital distributed ledger which has all the information related to the transaction. All this information is time-stamped and hence is easily trackable. Moreover, all the data is encrypted, and thus, it becomes difficult for anyone to alter or delete it. Since this information is distributed to all the nodes in the system, it becomes unalterable and immutable. The blockchain potential in financial services, therefore, needs to be exploited,” she adds.
She also maintains that banks will have the possibility to reduce the need for manual intervention in aggregating, amending and sharing data. Regulatory reporting and audit documentations could become easier, requiring less manual processing. As a result, employees could focus exclusively on value-added activities. “Reconciliation and settlement involved in various kinds of payments are clear examples of time-consuming and expensive processes that financial institutions can completely redesign by adopting blockchain technology. Financial firms may be able to keep track of the execution, clearing and settlement of transactions outside their legacy proprietary databases, without requiring the involvement of a central database management system,” she says further.
She, however, cautions that it is still an emerging technology, and there are outstanding open points related to security, regulation and scalability that need to be addressed. It may take couple of years to reach the maturity stage and become mainstream, she adds.
Prasanna Lohar, head – Digital, Innovation and Architecture at DCB Bank, describes blockchain as a unique opportunity for banks to change their lives in profound ways and unleash a set of new capabilities to transform the way “we interact and collaborate in our activities with better security and better authenticity of files”.
He says, as blockchain fosters trust among all stakeholders and minimize operational and manual overheads, it automatically eliminates the need for third parties and middlemen. It can prove a significant cost-saver. Also, as everyone gets to view a single immutable version of the ledger, cost and effort spent on documentation get reduced.
“Each bank will look for optimizing its operations and in a cheaper way, with a far lower error rate, with less resulting risks and lower capital requirement. They can reduce the need for manual intervention in aggregating, amending and sharing data, and regulatory reporting and audit documents could become easier, requiring less manual processing. As a result, employees could focus exclusively on value-added activities rather time consuming and error prone activities,” says Lohar.
He adds that reconciliation and settlement are clear examples of time-consuming and expensive processes that banks could completely redesign by adopting blockchain technology. Banks could be able to share a common digital representation of asset holdings and to keep track of the execution, clearing and settlement of securities transactions outside their legacy databases, without needing the involvement of a central database management system, he says.

Lohar lists 4 reasons for Indian banks to switch to blockchain:
1. The current day banking systems are highly reliable on paper and outworn process. The need of the hour is to have an upgraded system embedded with reliable and trust-able technology that could withstand frauds, scalability and security issues. The blockchain technology and its decentralized nature can give the banking systems the much-needed edge they are on the lookout for.
2. Banks cannot be termed as independently operating self-sufficient entities as any transactions made through them still involve intermediaries. Moreover, the rate at which money is transferred on an international scale can still take up to 5 days along with entailing risks. With a blockchain system in place, banks would be able to make transfers really quick without even having to take the burden of risks as the system would be self-sufficient to resolve it all on its own.
3. The world is going digital and with this progress, even small transactions and payments are happening digitally. The economic activity rate is increasing and there is no doubt in assuming that the rate will keep picking up in the coming days. Blockchain technology will make small transfers feasible and fast along with the aid of lower fee and scalability of transactions.
4. Financial services other than banks are constantly evolving their systems with the aid of the latest technology in order to secure the markets by providing economically available services at cheaper rates. Banking and other financial institutions should look forward to the adoption of new blockchain technology too in order to secure their place in the ecosystem.
Sony A, joint general manager and head – Digital Banking Dept, South Indian Bank, believes that in the light of increasing instances of frauds in the banking industry and the resultant overhaul that compliance exercise is undergoing, new technologies like blockchain can help reduce manpower and efficiently manage reconciliation efforts in the case of financial transactions. “Operational costs with regard to compliance and various legal adherences could also be reduced, thereby taking care of reputational and legal risks associated with the financial transactions,” says he.
He, however, does not advise a sudden switch for Indian banks. “The whole financial ecosystem might need to undergo a major behavioral shift to make blockchain and related technologies feasible. This is the reason why many banks have come together to launch business solutions in blockchain. South Indian Bank, along with other major banks, is part of one such consortium, with plans to provide solutions in the areas of trade finance and remittances,” he says.

Asit Oberoi highlights how with the adoption of blockchain, banks’ dependency on physical infrasructure and manual intevention for risk control will reduce

Jithesh P V, deputy vice president & head – Digital, Federal Bank, says the beauty of blockchain- based platforms is that the necessary information with respect to an approved use case is visible to all partners in the network based on the consensus created in the ecosystem. Hence, real time settlements are possible thereby improving efficiency. Says he: “In theory a distributed ledger is automatically reconciled, because the parties in a transaction could see the state of the transaction all the time. They do not need to cross verify and check with each other or wait for a file to know about the state of that particular transaction. Since participants are having access to true copy of the data, many of the use cases such as KYC could be achieved by preventing duplication of effort and time and thereby significantly improving customer experience and reducing costs.”
He points out that India being a large country with variety of financial institutions, businesses, regulatory authorities and end users, it is almost impossible to get each of these entities connected to every other entity. “Given the diversity of our country, we need mechanisms using which we could impart trust programmatically with automation. Blockchain is the only known technology which is capable of imparting distributed programable trust. I hope this will bring down the cost of business significantly since cost of trust is an important cost of business and this cost could be translated to end consumer benefits,” he explains further.
He feels it is inevitable for banks in the country to slowly adapt to this new technology because of the various other advantages it brings to the table like faster transactions, improved security, improved data quality, lower cost, transparency and of course interoperability and innovation.

Monish Shah of Deloitte shares a concern: “Every region is coming up with its own blockchain powered networks (consortiums). These regional consortiums have a risk of not being integrated, which could lead to disconnects at a global level. Therefore, the networks need to be integrated or standardized to truly unlock the benefits that come with using blockchain on a global level. Till then, scalability of blockchain remains a concern. Additionally, dispute management is still a challenge faced especially in transborder transactions, which no government has been able to address so far.
“The consolidation or integration of these regional consortiums would be essential in making blockchain a truly global technology for banking and thereby enhancing Indian banks’ reach to a global network of member banks as well as customers.”

Sunita Handa believes blockchain technology in cross-border payments can enable faster and more secure transfers between bank ledgers and this can help India’s financial institutions develop world-class payment platforms. Besides, the technology can enable banks to improve and future-proof their cross-border payments services.
She adds: “At present Indian banks communicate with banks in rest of the world through their correspondents, which takes time. In blockchain environment, there may not be need of correspondent banks and hence the communication will be faster. Information will be available simultaneously with all the participants.”
According to Asit Oberoi, the primary contribution of the technology to the banking sector as far as trans-border transactions are concerned will be in establishing and strengthening trust, bringing in transparency and reducing turn-around-time for a transaction. These will in turn bring in cost optimization as well increase business potential for the banks.
Says he: “Blockchain-based trans-border remittances are on the increase with several providers gaining momentum across the globe. The blockchain technology enhances the ability of Indian banks to improve their product offerings and increase revenue from such offerings. These technologies also provide an avenue to venture into new territories and new service offerings that were earlier not possible due to technological constraints arising from nonstandard implementations.”


Prasanna Lohar maintains that with the adoption of blockchain there will be need for international and national regulations around it will become mandatory

Prasanna Lohar of DCB Bank says financial and bank blockchain technologies bring in benefits such as lower costs and faster processing of transactions, elimination of intermediaries for transactions authorization, decentralization and thus, independence from central repositories, less paperwork and bureaucracy and above all transparency, data integrity and security
He is, however, cautious as he says blockchain technology in banking and finance faces some challenges. For example, current regulations and legislation do not allow the use of blockchain technology in finance, such as the prohibition of personal financial data immutability. There is need for improved security and platforms and applications that are used for blockchain transactions should have 100% protection against hackers and standards for identity verification on blockchain are yet to be developed.
Lohar is also reminding that the number of records and data sizes is increasing as the number of people continues to grow. “This poses a big challenge to the application of blockchain technology network. The network designed through a blockchain should be able to handle the growing volumes while maintaining the speed of accessibility for the network stakeholders. If the blockchain technology is applied to the current banking systems, it has to ensure the capacity of handling large volumes of data too. Scalability becomes important aspect to be taken care during blockchain application implementation,” he says.
Sony of South Indian Bank is of the view that business success of trans-border transactions depends on factors like speed, competitive rates and hassle-free settlement. “Currently, in our experience, our cross border transactions through various channels do happen in a near-to-real-time environment. Proactively involved in digital initiatives, we had done a pilot project in blockchain for remittance transactions where it was observed that the speed of the transaction was unvaried, compared to our existing channels. However, settlement and reconciliation of accounts can be more efficiently managed with blockchain.”
He adds that if blockchain is to make a real impact in remittances, the business model would have to change to an ‘aggregator’ approach wherein multiple exchange houses and banks would be part of the network, thereby reducing/sharing the costs involved.
Federal Bank too is facilitating real-time transactions for inward remittances with its current open banking capabilities. However, Jithesh feels DLT can give a different dimension to the product thereby bringing more transparency and hassle-free reconciliation while allowing real-time credit to accounts with all partner banks in the consortium. This will allow exchange houses and remitting banks to be more digital, while providing a level playing field for banks in the country even without having to partner with all the members in the ecosystem, he adds.
“As an example, for the remittance use case we also see the possibility of using smart contracts to make real time FX deals and thereby improve efficiency in the business process with a possibility of creating new business models for remittance, by passing more benefits to the end customers,” he adds.

Being a decentralized ecosystem, blockchain platforms allow multiple participants – even competitors – to have access to data. Is this a cause for concern?
Sunita Handa of SBI says information sharing is an important element of blockchain but exchanging and sharing information between competitors can raise competition concerns depending on the nature of the information being shared and the structure of the relevant market. She feels these concerns can be addressed with correct setup of blockchain protocols.
“It is essential to restrict the access to transaction records, in particular, commercially sensitive information such as contractual terms, sales volumes, pricing data and party names. This information should not be automatically shared with every user or node. An extra layer of privacy may need to be added to safeguard competitively sensitive information. Most private blockchain protocols have the possibility to segregate data for privacy purposes. It is necessary to recognize the correct protocols to be used for blockchain deployments. This is as much a matter of stake holders being educated about the data privacy maintenance,” says she.
She is also of the view that being an emerging technology, it is desired that the regulator should set up rules and frameworks, which should be applicable to all participants. New regulations, with role and responsibilities of each participant will increase trust among participant and will help to boost the usage of blockchain, says she.

Sony A feels with the use of blockchain operational costs with regard to compliance and legal adherences could be reduced, thereby taking care of reputational and legal risks

Asit Oberoi of Yes Bank points out that there are multiple variants of blockchain implementation like public, private and a hybrid of public and private. “Banks have been traditionally focusing on ownership of data due to the data sensitivity that must be adhered to by the financial institutions. Banks will be more inclined towards implementing a private blockchain network that would still be a decentralized one in nature. However, this ensures that stakeholders from the ecosystem can be part of the network to the extent of only being able to access data that is intended to be accessed by them. Non-financial stakeholders could participate in the blockchain network as an ancillary service provider through the public and private hybrid model to complete the end to end transaction journey enhancing customer experience,” says he.
He is confident that once the sector reaches a level of maturity and confidence on blockchain technology, the need for newer and simplified regulations will be vital from a customer experience perspective to enhance trust.
He says the regulators are very keen on exploring this technology, which is validated from the recent launch of the Vajra platform by NPCI for reconciliation and settlement of payment rails under NPCI and various other initiatives of RBI and other regulators in the financial industry to explore and implement industrywide blockchain applications.
Monish Shah says data privacy is restricted in private permissioned blockchains in which data access is restricted to only those participants who are supposed to be party to that transaction. Additionally, data resides within the premise of the transacting bank and actual data never flows through the blockchain rail. What essentially gets transmitted is a hash-pointer to the data stored in the bank’s database, which has a high level of encryption.
“However, while data security may not be an immediate concern, regulations would be needed to monitor the data in terms of data updation, storage, maintenance and archival and a robust ecosystem need to be established irrespective of the adoption at this stage,” he says.

Lohar of DCB Bank maintains that with the adoption of blockchain in the banking sector, the need for international and national regulations around it will become mandatory. “Recently we have seen how, cryptocurrencies, the most popular application of blockchain, do not have any regulations around them, which makes them susceptible to both profits and losses. However, blockchain has immense potential and certainly clear regulations need to be in place so as to avoid chaos,” he says.
Lohar points out certain existing weaknesses:
(i) Interoperability & Standardization: The technology does not have an international standard for competing blockchain systems. Better interoperability is needed to make blockchain compatible with the wider web and to integrate them into existing practices and processes.
(ii) Privacy: Data on blockchain technology is inherently shared publicly among all the participants of the system. There are various problems with respect to transaction privacy on blockchain as the data is made public and anybody can see it. Private blockchains are much secure, but they face interoperability issues.
(iii) Encryption: If the key is made public anybody can access the encrypted data and if someone loses the key to unlock the blockchain, it is impossible to get it back. Encryption used in blockchain technology may be broken through loopholes in the system as people may find out new ways to manipulate or misuse the data.
(iv) Security: Multi-level security must be in place which encompasses authorization of parties accessing blockchain, security from malicious insiders, cyberattacks, transaction security and infrastructure security. Blockchain systems can be permissionless or with permission, depending upon the nature of transactions.
(v) Scalability: With growth in blockchain applications, the need for a larger blockchain database is required along with the speed of access to database. Speed and accuracy of processing of a transaction will be of utmost importance to make it commercially viable.
(vi) Energy Consumption: There is enormous consumption of energy in the use of blockchain technology. It leaves a massive carbon footprint of its own. It requires huge computing power greater than the world’s fastest supercomputers.
(vii) Legal Framework: Blockchain technology and its applications lacks any national and international regulations. Though various governments across the globe are exploring the applications of blockchain, but still more clarity is required on the legal aspects.
Sony of South Indian Bank agrees this is a cause of concern. The banking sector, he says, is a fiercely competitive one and data privacy issues are of great importance and hence allowing multiple parties to access data is totally unwarranted. “We may have to rely on ‘permissioned blockchain’, wherein access to blockchain nodes would be restricted. It is seen that our central bank is taking a cautious approach in formulating the policies and guidelines in this regard. The maturity of the ecosystem will largely depend on regulatory vision and identification of viable models,” says he.
The issue concerns the use case and blockchain technology which are being used, according to Jithesh of Federal Bank. Says he: “There are third generation enterprise blockchain technology solutions which will help to achieve transaction privacy. We, at Federal Bank, could architect systems in such a way that entire data is not shared with all participants or competitors. There are different ways to create and manage policies in the blockchain architecture which can take care of the current and proposed data privacy and protection laws, regulations and business rules. I don’t see a need for any new regulation for such platforms.”

Jithesh PV is confident that use of blockchain will allow exchange houses and remitting banks to be more digital, while providing a level playing field for banks in the country

Several Indian banks have now become members of JPMorgan’s Interbank Information Network, or IIN, set up in 2017. Participating in the network is expected to help these banks to reduce payment delays with other member banks. The platform aims to create an infrastructure for global banks to exchange information on financial compliance and AML. As long as the data and system architectures for Indian banks are compatible with IIN, joining the network should not be a hurdle in terms of tech infrastructure. The network aims to keep data secure and free from data tampering, which is crucial for banking networks so fraudulent loans, cash flows, diversion of funds do not go unrecorded. It implements a layer zero-knowledge proofs (ZKPs) used with the Ethereum blockchain protocol. The network claims it is able to address data privacy issues.
Sunita Handa says that apart from preparing the tech infrastructure for blockchain implementation, Indian banks which have joined IIN, are trying to figure out how and where the network will bring them value additions. “Since these banks are competitors as well, there has to be unanimity on the type of information they would like to share with other bank participants and how exactly they will benefit out of that sharing. While data exchange with regulator or a central authority is done as a matter of regulation, transparency with other banks is something they would like to be very careful about. For dealing with peers in the financial industry, banks have always looked upon a neutral intermediary or a central authority or a regulator to finalize the rules and operative guidelines. Without a neutral intermediary, any one bank taking the lead and forming those rules will not find easy acceptability with other players. So, the IIN venture is new in more aspects than one,” she contends.
She also feels that any system that enables near to real time update of transactions helps in eliminating frauds and malpractices in cross border transactions. If implemented correctly by all participants, IIN can also do so. “If validation against sanction (negative) lists (eg OFAC or UN prohibited entities) are more efficient, it is bound to improve the quality of transaction transmission. The initial application on IIN may aim to create an infrastructure for financial institutions to exchange data on global financial compliance and for AML purposes,” she says.
Since data on a blockchain cannot be tempered with, she is of the view that attempts to commit fraud through data rewrite will not go unrecorded. “Many people say that India’s Punjab National Bank fraud case would not have happened if the global financial messaging network had used blockchain based consensus systems. However, if the representatives of a participant entity collude to circumvent or break all rules of checking and validation, any system including blockchain will not be able to prevent frauds,” she adds.
Asit Oberoi points out that IIN with 365 banks across globe as members will help Indian banks to scale their cross-border business, increasing efficiency by getting real time information on status of remittances. “With the recent developments in the tech world and with Indian banks including Yes Bank being proactive in adopting these emerging technologies, we are well placed to build infrastructure to connect to any such technologically advanced networks available across the world,” says he.

South Indian Bank, which is not part of IIN, is however, member of multiple consortiums with other major banks as members. Sony believes a consortium approach is very much helpful for exchange of ideas, discussions and diffusion of challenges and imbibing a shared sense of technological knowhow as well as costs. He reveals that the consortium in which the bank is a member, strives to take into account better fraud risk management practices and is in advanced stages to float a company with all the member banks.
The bank, he says, in its pilot project of remittance through blockchain, had ensured data privacy by engaging only the relevant business entity. “However, we may have to resort to permissioned blockchain in the case of consortium approach in order to manage data privacy issues. Blockchain can be deployed in both on-premise and in cloud. Both models will have appropriate security measures,” explained further.
Jithesh of Federal Bank says IIN is aimed at providing secure exchange information to banks associated with cross-border payments. It reduces costs and mitigates risks involved in those cross-border transactions. With IIN, the time taken to resolve these inquiries can be reduced from up to 16 days to mere hours.
He says Indian banking has some unique payment systems like UPI and IMPS which processes billions of transactions and all the Indian banks are together processing these transactions in a decentralized manner. It is therefore evident that Indian banking is more evolved and tech oriented than many international banks and hence joining IIN would not be a big challenge for any of the banks in the country.
Prasanna Lohar says 7 Indian banks joining IIN is a milestone. He points out that IIN may use a native cryptocurrency JPM coin to help move funds and provide liquidity. The network, he says, aims to make global banking faster & more efficient by exchanging and verifying transactional data in real-time. He also explains that IIN is based on Quorum, a permissioned distributed ledger whose code was forked from the Ethereum public blockchain. Unlike the Ethereum network, Quorum is not decentralized and is controlled by JP Morgan. It has enjoyed an extensive network of participant banks – about 350 global banks – which collectively own trillions of dollars in assets. He also points out that the network also aims to keep data secure and free from tampering. Besides, fraudulent loans, cash flows and diversion of funds do not go unrecorded.
With regard to security, Lohar points out that Facebook’s Libra blockchain project failed to convince critics. However, JPMorgan, in order to ensure user privacy, has implemented a layer zero-knowledge proofs (ZKPs) used with the Ethereum blockchain protocol.

Fundamentally, says he, the blockchain network is secure and powerful as it is embedded with cryptography techniques. “Blockchain based cryptographic networks are very complex to breach or hack and thus, any kind of security fraud in such networks would require a high amount of computational power in order to secure any hack. When a blockchain network is applied to any banks, it has to be secured with multiple security protocols. The blockchain network design should be capable enough to restrict participating authorities to take control of the network only according to the access permission given to them. Depending on the requirement and use cases, the blockchain involved in such systems or organizations could be designed permissioned or permission-less. People aspect in an organization need to be handled with different levels of access permissions in order to save the overall network from malicious insiders and cyber hackers, he says.
Lohar lists some of the blockchain projects in India:
Bankchain, which is the State Bank of India’s effort along with DCB Bank, ICICI Bank, Kotak Mahindra Bank and other commercial banks, IBM, Microsoft, Skylark and KPMG in 2017. The consortium completed several pilots in 2017-2018, enabling its members to share KYC, AML and CTF details over a blockchain.
The Reserve Bank of India affiliate Institute for Development and Research in Banking Technology is working on the use of blockchain for the Indian banking system.
Yes Bank is working a blockchain-based project to bring some 33 vendors on board an invoice financing blockchain.
Axis Bank has developed an inward remittance solution based on blockchain along with RAKBank. It will cater to the retail customers of the Middle East. The bank has also aligned with Standard Chartered Bank (Singapore) to develop a solution for corporate trade remittance. The bank is using Ripple for creating the network.
ICICI Bank is working on a closed-loop wallet for use in campus transactions. It has also developed 2 blockchain-based solutions with Emirates NBD for remittance and trade finance.
DCB Bank has conducted 7 Hackathons around blockchain and it is closely working with IDRBT, NPCI, various institutes, startups and fintechs for adoption of blockchain.
Infosys Finacle and R3 have completed a 5-week long global blockchain trial.
India’s income-tax department has done pilots with DCB Bank, Kotak Bank and other banks to create blockchain-based IT returns.
NPCI’s Vajra Platform is intended to be based on an open-source technology/ framework/solution.

Sunita Handa finally explains that blockchain technology is a core, underlying technology with promising application prospects in the banking industry. “It provides a way for parties who don’t fully trust each other to come to agreement on the state of a database, without using a middleman. By providing a ledger that nobody administers, a blockchain could provide financial services like payments, securitization, Central KYC or other validations etc. Further, blockchain allows for the use of tools like ‘smart contracts,’ which could potentially automate many of the manual processes.
She says DLT could help in use cases that don’t need a high degree of decentralization but could benefit from better coordination. Some of these, according to her are Clearing and Settlement Systems, Securities, Trade Finance and Securitization of assets by banks/ financial institutions.
She adds that SBI is doing pilot projects using blockchain including inward remittances from a particular international geography and in financing of car dealers on the basis of Virtual Identification Number or VIN of each vehicle acquired or sold by the dealer.
Monish Shah says delivering trade finance optimally is one of the most tried and tested use cases on the blockchain platforms. The technology has helped create more transparency and security by replacing the existing complex documentation process in the domain, leading to a higher degree of trust among trade parties globally.
He is also sure that payments and clearance and settlement systems will continue to be among the domains disrupted by blockchain technology. “Distributed ledgers can reduce operational costs and bring us closer to real-time transactions between financial institutions. Furthermore, it can facilitate faster payments at lower fees by establishing a decentralized ledger for payments,” says he.
