How Blockchain Technology Works: A Simple Explanation for Nigerians

Introduction

Okay, so let’s discuss this “Blockchain” everybody’s been raving about. It sounds all really high-tech, like something out of a science fiction film or whatever, but believe me, the overall concept isn’t that complicated, sorta like how we keep books in our own communities, only with a more modern, electronic system. We’re going to simplify it in a manner as if we’re speaking in a buka, no complicated grammar or jargon, just plain talk for my Nigerian people.

Suppose say, in your neighborhood, there’s this much-valued record book. The book contains who owns what property, who took money from the area cooperative, or perhaps who donated what to the recent neighborhood project. Now, this is not simply any book. It’s got a few special rules:

-Everyone Has a Copy: Rather than one book being held by one individual, think of it as if each member of the community has his or her own copy of this record book that is identical. So if I have a transaction with you – for example, if I sell some of my farm to you – this transaction isn’t recorded in one book. It’s recorded in all books.

-New Entries are Publicly Verified: When there’s a new transaction, such as our sale of land, it’s not written down quietly. Rather, it’s broadcast to the community. Before it’s added to everyone’s ledger, a few prominent members of the community (think of them as honest elders or leaders) verify that the transaction really did occur. Did I really own the land? Did you really pay the price we agreed on? When they give the thumbs up, then…

-Once Written, It Can’t Be Erased (Easily): Once the transaction is settled, it is written on a new page in everyone’s books. What is interesting is that these pages are linked in a sequence of time, like chapters in a book. And once a page is completed and cross-checked against the previous page, it’s extremely, extremely hard to go back and make a change on a prior page without anyone ever knowing. If someone tries to alter their copy, it will not be similar to everybody else’s, and the altered one will be easily recognized as bogus.

-These Pages are Like “Blocks”: Consider each of these pages to be a “block.” And since these blocks are linked together in order and secure, that’s how they become known as “blockchain” – a chain of blocks with information.

That, in short, is roughly the way blockchain works. It’s an open, distributed, and highly secure means of storing data. Rather than depending on some single authority (e.g., having a sole person responsible for the record book), that work of maintaining the records and certifying them is shared among a large number of participants.

Applying It to Our Nigerian Situation: Trust and Transparency

Therefore, why is this “blockchain” so important and why are all these people in Nigeria now so fascinated with it? Look at some of the problems we have to contend with:

-Trust Issues: At times it is hard to trust individuals or institutions even for critical records or transactions. Blockchain’s transparency and decentralized nature can make it easier to trust since every person holds a copy and every transaction is authenticated by several parties. It is similar to having many witnesses to each agreement.

-Land Disputes Over Property: Land disputes are prevalent in the majority of Nigeria because of unclear or doctored records. Consider a land registry on blockchain. All land transactions would be publicly recorded and irrevocably, so it would be very hard for false claims to happen. All would have an established, provable history of ownership.

-Preventing Corruption: Transparency is also one of the best weapons to prevent corruption. If government spending, like contracts awarded or cash paid out, were recorded on an open blockchain, it would be much more difficult to keep secret where the money is going and hold individuals accountable.

-Financial Inclusion: It is difficult for most unbanked Nigerians to access normal financial services. Cryptocurrencies, which most of them utilize the application of blockchain technology, can provide a substitute for the remittance and receipt of money, without the banking system. The farmer in the village can be imagined as being capable of receiving payment on his crop from a mobile phone using a blockchain currency.

-Hidden in Plain Sight: Consider the food we purchase or the medicine we ingest. Would it not be wonderful to know where they came from and how they arrived? Blockchain technology can be applied to trace products as they move through the supply chain, providing authenticity and quality assurance. For instance, you can scan a stamp on a bag of rice and know exactly where it was cultivated, processed, and packaged.

The Techy Bits (But Not Too Techy): How it Actually Works

Alright, let’s pop the hood a little but not become too techie:

-Transactions: When someone wishes to make a transaction (say, transfer money or store a block of information), it’s grouped with other transactions all together into a “block.”

-Hashing: A random digital fingerprint in the form of a “hash” is created for every block. The hash is a kind of secret key that encrypts all data that is present in the block. If even a single piece of data in the block is altered, then the hash is completely altered. That’s why it is easy to verify if a block is tampered with or not.

-Linking Blocks (The Chain): The new block will hold not just its own hash but also the hash of the last one. This forms the “chain.” If anyone tries to tamper with a block somewhere in the middle of the chain, its hash will be different and no longer match the hash of the next block, instantly revealing to all nodes across the entire network at once the tampering.

-Decentralized Network: Rather than everything being on one machine, the blockchain is on a network of multiple computers (such as our community people all sharing the book). Decentralization makes it very robust and impossible to attack or close down.

-Consensus Mechanisms (The Verification Process): Think of our good community members checking for truthfulness In blockchain, this is achieved through several “consensus mechanisms.” One of them is “Proof-of-Work,” where computers compete to solve complex maths problems so that they can be allowed to validate transactions and add blocks to the chain. The second one is “Proof-of-Stake,” where the users “stake” their own coins in hopes of getting in line for the opportunity to validate transactions. These mechanisms allow all participants to confirm that the transactions are valid before they are recorded.

Uses Outside of Cryptocurrencies:

While blockchain is most widely known through its connection to cryptocurrencies like Bitcoin, the technology itself has many other uses. Some of them are:

-Life Style:

-One single digital identity to which one might see oneself safely attached in a blockchain. It would be safer and simpler to vote, get government services, and demonstrate competence.

-Health Care Records:

-Storing and sharing health information safely with the actual owners might just make it all easier and permit more care for the patients. Patients can take more control over data around them.

-Intellectual Property Protection: Writers, artists, and inventors can utilize blockchain to stamp and safeguard intellectual property, easier identification of ownership, and avoiding copyright infringement.

-Voting Systems: Blockchain can make online voting systems secure and transparent, less opportunity for fraud and complete voter confidence in voting.

Supply Chain Management (Again): Farm-fresh to finished product, with all out in the open and on the level in between. You can even trace where your tomatoes were grown and how.

Challenges and the Nigerian Context

Of course, as with all new technology, blockchain has loopholes, largely in the Nigerian context:

-Infrastructure: Unstable internet access and availability of electricity are not yet as prevalent in Nigeria and might constrain the usage of blockchain technologies.

-Regulation: Regulation of blockchain and cryptocurrency is still in the development stage. Facilitatory and enabling regulations have to be crafted to provide freedom for innovation but also to secure consumers.

-Man vs. Machine: Most of the public are not aware of the technology behind blockchain and how it can be used. Adoption on a mass scale through awareness campaigns and education is required.

-Trust and Security Issues: It is secure by design, but it must be taught how to use blockchain-based systems securely, and not be misled.

-Scalability: Some blockchain networks have challenges supporting high quantities of transactions smoothly. Scalability measures are being dealt with on a full-time basis.

The Human Aspect: Opportunity and Empowerment

Blockchain is all about empowerment of people and communities and bestowing power by providing them a more decentralized, more transparent, and more secure method of dealing with information and value. In Nigerians’ lives, it will mean:

-Reducing the reliance on middlemen and trusting transactions and keeping records.

-Money Inclusion: Improving access to financial services among the underbanked and unbanked.

-New Economic Opportunities: Generating new job and business opportunities in the blockchain and cryptocurrency sector.

-More Efficient Processes: Various processes being streamlined from land registry to supply chain management.

-Increased Transparency and Accountability: Minimizing the scope for fraud and corruption to take place.

Envision a situation in which a Benue farmer can sell yams to a consumer in Lagos on a blockchain platform, receive secure payment and traceable transparency of the crop. Envision a tech start-up young entrepreneur in Yaba designing a blockchain site to authenticate qualifications such that it becomes more difficult for forged certificates to exist. These are mere visions of what is possible.

In Conclusion: A New Way of Keeping Our Community Record Book

Blockchain technology, in summary, is a new and improved way of keeping our community record book – an open common one that is secure and almost impossible to hack. Although its nerdy attributes are thick, its ideals are very human and relevant to our Nigerian realities. As the infrastructure and technology become better, we can utilize blockchain to address some of our biggest challenges and give us new channels of economic opportunity and social empowerment. It is not gee-whiz technology; it is adding more trust, transparency, and efficiency into systems that govern us. And we all get to enjoy it and be part of it.
