Why Blockchain is gaining popularity

Since its conception, people have been fascinated by blockchain, an emerging trend in fintech. The purpose of blockchain was to enable digital data to be recorded and appropriated but not altered.

Stuart Haber and W. Scott Stornetta, two researchers who aimed to develop a system where document timestamps could not be tampered with, initially proposed blockchain technology in 1991. Blockchain did not have its first real-world application until two decades later, with the launch of Bitcoin in January 2009.

Although blockchain may appear complicated at first glance, its underlying concept is simple. Blockchain is a specific type of database, and the way its data is structured differs significantly from a typical database. A typical database stores data in a particular way, for example, by using a table structure. Most databases use a relational data model, showing that all the information is stored in relation to each other and accessible using keys.

In blockchain, each block stores data in a unique way, which makes the system very secure and reliable. There is no linkage between blocks and records in blockchain because there is no need for that. The main idea behind blockchain – unlike databases – is that no central authority controls the database. Instead, all members of the network have an equal say in managing it. This allows for flexibility and transparency, as any client can check the contents of a transaction or database item without relying on a central authority. To do this, only one entity must be replicated on each machine in the network – the blockchain itself.

To understand blockchain, it is necessary to first understand its storage structure. Blockchain differs from typical databases in the way it saves data. It stores data in blocks that are linked together. As new information is received, it is entered into a new block. Once the block has been filled with data, it is linked onto the earlier block, resulting in a chronological chain of data. When a block is filled, it becomes a permanent part of the timeline. When a block is added to the chain, it is given a precise timestamp. Any change to a single block in a chain would be immediately obvious. Hackers would have to modify every block in the chain across all distributed copies if they wanted to destroy a blockchain system.

With the recent emergence of cryptocurrencies which are built on blockchain like Bitcoin and Ethereum, new blocks are constantly being added to the chain, greatly increasing the ledger’s security. Bitcoin depends on blockchain technology as a mechanism of recording payments in a transparent manner. Bitcoin was developed in 2008 by Satoshi Nakamoto, a designer who built the digital currency, as a peer-to-peer electronic cash system which does not require third party intermediaries. It runs as a decentralized, transparent, secure and distributed electronic cash system where the history of every transaction done is made public and can be viewed by anyone at any time. The Bitcoin ledger is collectively kept by a network of participants [nodes] spread across the globe. All nodes in the network keep track of all successful transactions and update their copies of the ledger accordingly.

A South African-based marketplace known as Sun Exchange allows individuals to invest in solar energy projects in South Africa using Bitcoin. Anyone with Bitcoin can buy solar energy systems, and lease them to schools, communities, businesses, and government facilities. This allows investors to earn rental income, while supplying clean energy to local communities in areas which have a critical need for energy infrastructure. It primarily focuses on South African solar projects but is expanding to other African countries like Kenya.

African fintech startups have made noteworthy progress in changing the landscape of the blockchain industry. Tari, an innovative South African blockchain startup launched in 2018 has a goal to integrate payment solutions across Africa. They are also in the game of supporting local African blockchain startups through a free blockchain university to spread blockchain knowledge across Africa.

Blockchain has potential applications beyond Bitcoin. Blockchain is an immensely powerful technology that can revolutionize multiple industries. It enables users to store information and share that information with others without the need for a trusted third party to ensure security. This means that all data is maintained privately, which provides users with complete privacy in their transactions.

Blockchain also has applications in finance, healthcare, energy, and other fields where trust and security are important. One good example is the use of blockchain to vote in democratic elections. The nature of blockchain’s immutability means that fraudulent voting would become far more difficult to occur. Here, a citizen is issued a single cryptocurrency or token under a voting system. Each candidate is then assigned a unique wallet address; hence voters would send their tokens or crypto to the address of the candidate they wish to support. Because blockchain is transparent and traceable, it eliminates the need for human vote counting and the ability of bad actors to interfere with physical votes.

Health care providers can leverage blockchain to keep their patients’ medical records securely. When a medical record is created and signed, it can be stored on the blockchain, giving patients confirmation and assurance that the record cannot be altered. For example, BurstIQ, a US based tech company creates big data blockchain contracts to help their patients and doctors transfer sensitive medical information securely. The smart contracts set up the parameters of what data can be shared and even displays details of personalized health plans for each patient. 

Propy is a global real estate marketplace which leverages blockchain to create a decentralized title registry system and even sells properties that can be bought using cryptocurrency.

Launched in 2015 by Cellulant, Agrikore is a blockchain-based system for intelligent subcontracting, payment, and marketspace that allows all stakeholders in agriculture (farmers, consumers, product aggregators, insurance companies, financial institutions, and governments) to collaborate in a secure environment.

With many practical uses for the blockchain technology being implemented and explored, blockchain has the potential to make businesses and even government operations more precise, efficient, secure, and cost-effective by eliminating the need for intermediaries and giving comfort to its users.

An Industry on the Rise

Financial Technology services have become essential for today’s highly connected consumers.

Over the years, Ghanaian Fintech companies have become a gateway to access digital financial services by providing inexpensive and more accessible financial solutions for Ghanaians.

The fintech industry has fostered financial inclusion and progressed in the direction of a cash-lite economy, driven by digital products and services. There has been a significant level of growth over the past years in response to emerging trends and technologies like Insurtech, Blockchain Technology, Big Data and Artificial Intelligence. Leveraging these technologies, Fintech companies are also partnering with financial institutions to make digital financial services convenient and accessible. This has seen the rise in Banking Application and USSD codes for banking purposes. GCB Bank through its e-money service called G-money has made financial services convenient, accessible and available via USSD, App, and a QR Code.

To further redefine the delivery of financial services, Nsano created a technologically-driven, user-centric solution called Move Secure, a Mobile Money escrow service, to curb the growing mistrust and online scams within the e-commerce space.

On the regulatory front, the Central Bank has demonstrated its support for the Fintech industry with the launch of a new FinTech and Innovation Office in May 2020, to drive the Bank’s cash-lite, e-payments, and digitization agenda.   

In February 2021, The Bank of Ghana also launched a regulatory and innovation sandbox pilot; a regulatory environment that enables firms like banks, specialized deposit-taking institutions and payment service providers to test innovative products, services and business models to assess their usefulness and viability in the market.

The Central Bank further cemented their support by for Financial Technology with its recent announcement to introduce the e-cedi, a state-backed digital currency, making it one of the first Central Banks to enhance digital financial services in Africa.

For a majority of Ghana’s population, digital technology has become the driving force for financial services. With these technologies and trends, the Fintech industry has more room to grow and innovate to provide the digitization that the world has acknowledged as the way forward.

Tech For Good: How Move Secure is Curbing Mobile Money Fraud

In response to the growing menace of mistrust and scams within the online commerce space, a new Mobile Money escrow service called Move Secure has been launched to facilitate safe and secure transactions on Mobile Money.

The service operates by holding money in trust till both vendor and buyer confirm their satisfaction with a transaction. This is a much-needed solution to restore the declining levels of trust between online buyers and vendors resulting from increased cases of scam.

For buyers, Move Secure ensures that even though you have initiated payment for a service, you can get your money back seamlessly in the event of an attempted scam or if the wrong/inferior order is delivered. It also shows a commitment to your vendor to prioritize your order.

For vendors, the service shows a payment has been made before you make a delivery, eliminating the potential of wasting time or money to transport orders to customers who don’t show up.

Both parties can raise disputes within the Move App or via the USSD code (*718*8#) in an event where one party is dissatisfied with the exchange.

“We believe in using technology to solve everyday problems. With the increasing rate of mistrust in online payments and trade, we came up with this escrow service on Mobile Money to give both buyers and sellers comfort in the exchange process. This we believe will also eliminate fraud and scams in online commerce for our Move Secure users.” Mrs. Linda Otoo, Country Manager for Nsano commented about the service.

To use Move Secure, simply dial *718# and choose option 2. You may also download the Move GH app on Appstore or Play Store.

Nsano Receives Payment Service Provider (Enhanced) License.

The Bank of Ghana has awarded the first ever Payment Service Provider (Enhanced) License to one of the nation’s foremost financial technology companies, Nsano Limited.

As part of efforts to foster soundness in the financial services sector, the Ghanaian Central Bank has tightened its controls of the country’s financial ecosystem; consolidating and formalizing its oversight of financial technology companies in order to promote innovation and growth, without jeopardizing the safety, security, and stability, of the financial services sector. The Payment Systems & Services Act 2019 (Act 987), provides the legal and regulatory framework for the orderly development of Ghana’s payment system and grants the Bank of Ghana the mandate to duly license and supervise financial technology companies operating within the country.

Nsano Limited, a diversified financial technology solutions provider which currently maintains its focus on building custom mobile financial service applications for banks and insurance companies, providing merchant payment solutions, offering remittance services, and playing the role of an aggregator in connecting various entities to the nation’s mobile money operators, is the first to have been granted the Bank of Ghana Payment Service Provider (Enhanced) License.

The license, among other things, supports the provision of services including electronic funds transfer, facilitation of interoperability of payment systems and services, payment system aggregation, provision of electronic platforms for payment or receipt of funds, and the provision of technological services to facilitate switching, routing, clearing and data management. Obtaining the license buttresses Nsano’s position as a progressive industry leader, and a formidable technology partner of financial institutions, merchants, digital solution providers, remittance companies and other fintechs aiming to be guided to obtain a PSP (Standard) License.

Following its establishment in Ghana some years ago, Nsano launched operations in other markets across Africa including Zambia, Uganda and Cote d’Ivoire, in a steady attempt of realizing its vision of processing 50% of Africa’s GDP by 2025.

The PSP license which follows closely after the company’s ISO 27001:2013 certification, the unveiling of its state-of-the-art Fraud Centre, and the award of the Remittance Grant Facility, is indicative of the company’s commitment and adherence to international best practices and world class standards in ensuring customer protection and satisfaction, inhibiting fraud, as well as contributing its quota to promoting digitization, financial inclusion, and inclusive sustainable economic development.

Whilst expressing excitement at the award of the license, Mr. Kofi Owusu-Nhyira, a director of the company, indicated that it was a privilege to serve the country, particularly in such times when the COVID-19 pandemic has revealed the true essence of digital financial services. He also took the chance to pledge the company’s commitment to playing its part in innovating and adapting in response to the country’s financial technology service needs during these unusual times, and to support the Bank of Ghana in leveraging digital channels to minimize risks and operational disruptions to both customers and providers of financial services.

Payment Ecosystem: How Account to Wallet Transactions Really Work

Today, most African’s have bank apps (either USSD/Android/Mobile Apps) that are used for financial transactions. These apps save time and reduce bank queues. Whether you are using a USSD or Mobile App, a number of invisible technological processes take place before your transactions are finally processed and your payments go through.

Most banks in Africa work with FinTech platforms to enable you perform transactions from your Bank Account to your mobile wallet. FinTechs like Nsano are the hidden players that sit in the middle of these transactions ensuring that payments are smoothly done.

If you have ever wondered how your funds move from your bank account to your mobile wallet, this infographic reveals the science behind it all!

Nsano Receives USD 250,000 Remittance Grant Facility

Nsano Group was on Wednesday 19th June 2019, awarded a grant of $250,000 under the second phase of the Remittance Grant Facility (RGF) challenge.
The project is to support companies to develop affordable and accessible products and services that extend the scope of remittances to the rural areas as well as benefit Ghanaians in the diaspora.



The Remittance Grant Facility (RGF) was launched by the Governments of Ghana and Switzerland in May 2017. The $2.6 million fund financed by Switzerland through its State Secretariat for Economic Affairs, is to provide financial assistance to companies to develop innovative remittance products and services at a relatively low cost. The fund is also managed by KPMG International Development Advisory Services.


Mr. Sampson Akligoh, the Director of Financial Services at the Ministry of Finance, at a ceremony to present the cheques to the beneficiaries, said the objective of the facility was to reduce the cost of remittances and extend their reach to the rural poor as well as benefit Ghanaians in the diaspora.

He said the remittance market in the country faced challenges with a high cost of charges and accessibility. On 16th June 2019, the world marked the International Day of Family Remittances and noted that remittances had a direct impact on the lives of over 1 billion people all over the world. The remittance market in Ghana faces challenges of high cost of charges and accessibility.

To this end, Mr. Akligoh said the Remittance Grant Facility (RGF) provided grants to support the design and pilot testing of products and services that were affordable to target customers, encourage savings and investment.

He said the challenge would help address operational pitfalls associated with remittance flow channels into the country and to encourage innovative product and service development.
Mr. Daniel Lauchenauer, the Deputy Head of Cooperation, Embassy of Switzerland in Ghana, said the initiative was to ensure that companies got funding to pursue projects that would help mitigate and increase challenges in the remittances market.

He said the partnership was necessitated by the long economic and diplomatic relationship with Ghana, adding that the Facility, when utilized effectively, would spur economic development in the rural areas and contribute to the ‘Ghana Beyond Aid’ agenda.

Kofi Owusu-Nhyira, the Chief Executive Officer, Nsano Group, also commended stakeholders for selecting Nsano for the grant and pledged to continue to use the platform to address challenges in the remittances space and build the livelihoods of the poor.

Nsano Receives ISO 27001:2013 Certification; Unveils Fraud Center

Nsano Ltd, one of Africa’s pioneer FinTech companies, has unveiled its high-level fraud management center, as part of key initiatives to boost security as well as standardization of its Information Security Management (ISMS) processes which led to the award of the ISO 27001:2013 certificate.

Nsano is a financial technology firm operating in 8 African countries. The company specializes in electronic payments and liaises with telecom providers and payment processors to provide services to its clients and third parties.

Fraud levels in the e-payments industry have increased across different markets in Africa. Hence, Nsano’s security focus is a step to ensure robust operations in the various markets in which it operates.

Members of the Nsano Management team receiving the ISO 27001:2013 certificate

The Nsano Fraud Management center is a comprehensive security system integrated to platforms of financial institutions. The center consists of fraud experts and systems which are able to detect in real time, any fraudulent activities on the institution’s platform and prevent them from being processed. The center provides a 24-hour fraud monitoring service and assistance to all clients. It is the first of its kind operated by a FinTech firm on the Ghanaian market.

“We are committed to ensuring the security and privacy of our platforms and this commitment has led to the establishment of the Nsano Fraud Management Center and an audit of our processes to ensure it meets the standards of ISO 27001:2013. Our certification today is testament to our coordinated efforts in the area of security and we will roll out similar initiatives across other markets in Africa. Mrs. Linda Otoo, Chief Operations Officer of the company said.

Mr. Kofi Owusu Nhyira, the company’s Group CEO also added that, “Nsano’s renewed focus on platform and information security is to give our clients the assurance that their transactions and data are secure so they can truly experience the value of seamless e-payments”. The ISO 27001:2013 was issued by PECB after an auditing process carried out by Innovare, an independent ISMS auditing firm.

The Fraud Management Center and the ISO 27001:2013 certificate are major steps in the company’s roadmap to tackle security in payments.

Nsano looks to expand its operations to other African countries, as it innovates to develop payment solutions that ensure financial inclusion for all.
