A child who has never travelled believes their father's homestead is the whole world.
Technology often makes many of us feel like that child. We hear new words, nod politely, and quietly hope someone will explain them in plain language. Few technologies have attracted as much excitement—and confusion—as blockchain and NFTs.
For years, these two terms have appeared alongside stories about cryptocurrencies, million-dollar digital art, scams, and overnight fortunes. Somewhere in that noise, many ordinary people concluded that blockchain was only for investors, programmers, or people chasing the next big thing online.
Yet that is far from the truth.
The real story of blockchain is not about speculation. It is about trust. It is about keeping records that people can verify without depending entirely on one individual or institution. NFTs, meanwhile, are not simply expensive digital pictures. At their heart, they are a way of proving ownership of something unique in the digital world.
Understanding both begins not with computers, but with something much closer to home.
Imagine your grandmother's granary.
Everyone in the village knows how many sacks of maize went in after harvest. Whenever a sack is removed, everyone who helps with the granary can see it. Nobody quietly sneaks in at night and changes last month's count because several people already know what was recorded. Trust comes from shared knowledge rather than blind faith.
That simple idea lies at the heart of blockchain.
Trust, Written One Page at a Time
Think of a notebook used by a merry-go-round (chama). Every contribution is written down. Every member has seen the entries. If someone tears out a page and replaces it with different numbers, the rest of the members immediately notice because their own records no longer match.
Blockchain works in much the same way.
Instead of one notebook locked inside an office, identical copies of the record exist across many computers. Each new page of transactions is connected to the previous page, forming a continuous chain. Once information has been agreed upon and added, changing it becomes extraordinarily difficult because every copy would need to be altered simultaneously.
Rather than relying on one trusted gatekeeper, the system relies on many participants verifying the same information.
As The Truth Machine, economists Michael J. Casey and Paul Vigna observe, blockchain represents "a machine for creating trust." That simple description captures its greatest strength. The technology does not eliminate trust altogether; instead, it changes how trust is established.
*Why This Matters Beyond Computers
*
Imagine buying a plot of land.
You receive the title deed and carefully lock it away. Years later, another person appears claiming ownership with a different document. The dispute drags on for months, perhaps years.
Now imagine if every legitimate transfer of ownership had been permanently recorded in a system where altering past records without everyone noticing was practically impossible.
That is one reason governments, researchers, and businesses continue exploring blockchain technology—not because it is fashionable, but because reliable records matter.
The World Economic Forum has repeatedly highlighted blockchain's potential in improving transparency across supply chains, healthcare, trade documentation, and public services.
The technology is not a magic wand, but it offers a different approach to keeping records honest.
A Kenyan Story Hidden Inside Your Morning Cup of Coffee
Picture a farmer in Nyeri harvesting coffee cherries.
The beans leave the farm and pass through processors, exporters, shipping companies, warehouses, and finally a café somewhere in London or Tokyo.
Along the journey, information can easily disappear.
Which farm produced these beans?
Were farmers paid fairly?
Was the coffee organically grown?
Blockchain allows every participant in that journey to add verified information as the product moves from one stage to another. Instead of relying on one company's records, everyone along the chain contributes to a shared history.
The result is greater traceability.
Several agricultural supply-chain projects around the world—including initiatives involving IBM Food Trust and similar traceability platforms—have demonstrated how distributed ledgers can help consumers understand where products originate and how they reached the shelf.
The same thinking could extend beyond coffee.
Imagine purchasing beef in Nairobi and scanning a QR code that tells you which county the animal came from, when it received veterinary treatment, where it was slaughtered, and how it reached your local supermarket.
For livestock-producing countries like Kenya, such transparency could strengthen consumer confidence and improve access to export markets that increasingly demand traceable food systems.
*So Where Do NFTs Come In?
*
Suppose your grandfather carved a beautiful wooden stool.
It is the only one he ever made.
Many people can photograph it.
Others can paint it.
Someone might even create an exact replica.
But only one original exists.
An NFT—or Non-Fungible Token—acts like a digital certificate proving ownership or authenticity of something unique.
The word non-fungible sounds intimidating, yet the idea is familiar.
A KSh 1,000 note is fungible because any other genuine KSh 1,000 note can replace it.
Your national identity card is not fungible.
Neither is your university degree.
Neither is your passport.
They belong specifically to you.
NFTs apply this same principle to digital assets.
Contrary to popular belief, the NFT is usually not the artwork itself. Instead, it is a digital record pointing to ownership or authenticity.
That distinction matters.
Owning an NFT of a photograph does not automatically stop others from viewing or copying the image online, just as owning the original Mona Lisa would not prevent people from printing posters of it. What changes is who possesses the recognised original.
Beyond Digital Art
The headlines often focused on colourful digital images selling for extraordinary sums.
That created the impression that NFTs were little more than expensive internet collectibles.
Their practical uses are far broader.
Imagine receiving your university certificate as an NFT.
An employer could instantly verify its authenticity without calling the institution.
Imagine concert tickets issued as NFTs.
Counterfeit tickets become far harder to produce.
Imagine hospital records where patients control access to their medical history instead of carrying paper files from one clinic to another.
Imagine land titles, professional licences, intellectual property rights, museum collections, or even livestock ownership represented through secure digital certificates.
Many of these ideas remain under development, but the underlying technology already exists.
*Not Every Problem Needs a Blockchain
*
Good technology should solve real problems rather than create new ones.
Blockchain is no exception.
Traditional databases are often faster, cheaper, and easier to manage.
If a small family business only needs to record daily sales, an ordinary spreadsheet may work perfectly well.
Blockchain becomes valuable where many independent parties need to trust shared records without placing complete confidence in one central authority.
It is a specialised tool—not a universal solution.
As the old Luo saying reminds us, "Piny owang' ni ng'ato ok nyal bedo gi rieko duto." The world has taught us that no one possesses all wisdom. Likewise, no single technology solves every challenge.
The Challenges We Should Not Ignore
Balanced conversations matter.
Blockchain systems can be expensive to build and maintain.
Some public blockchain networks have historically consumed significant amounts of electricity, although newer systems increasingly rely on energy-efficient methods such as Proof of Stake, reducing electricity use dramatically compared with earlier designs.
There are also legal questions.
Who owns digital assets?
How should governments regulate them?
What happens when mistakes occur in records designed to be difficult to change?
Fraud remains another concern. Scammers often exploit public excitement around NFTs and cryptocurrencies. Importantly, these scams usually arise from dishonest people, not from the blockchain technology itself.
As with mobile banking or online shopping, understanding the technology is one of the strongest forms of protection.
*Looking Ahead
*
Blockchain and NFTs are still evolving.
Some ideas will succeed.
Others will quietly disappear.
That is how innovation has always worked.
Few Kenyans imagined twenty years ago that sending money through a mobile phone would become an everyday habit. Today it feels ordinary.
Blockchain may follow a similar path—not because everyone suddenly becomes a cryptocurrency trader, but because the technology quietly finds practical uses in areas where trust, transparency, and reliable records matter most.
When that happens, many people may use blockchain every day without ever noticing it, just as millions of people send mobile money without thinking about the complex systems operating behind the screen.
Technology is at its best when it disappears into everyday life.
Perhaps that is the simplest way to understand blockchain.
It is not trying to replace human trust.
It is trying to help us record trust more faithfully.
And NFTs?
They simply answer an old human question in a new digital world:
_"How do we know this truly belongs to you?"
_
The answer, increasingly, may not come from a filing cabinet or a rubber stamp, but from a carefully maintained digital ledger shared across the world.
