Kayode Popoola, known professionally as Popeblack, began building communities long before he had finished university. Based in Nigeria, he combined his studies with work, developing the discipline and stamina that would later carry him from grassroots community building into business development, privacy technology and blockchain intelligence.
His introduction to cryptocurrency was largely accidental. Popoola was completing online research and surveys when he received a payment in Bitcoin. At the time, he knew little about blockchain and was primarily interested in receiving payment for the work he had completed. Curiosity prompted him to investigate further.
He began researching Bitcoin, blockchain and the communities developing around them. Much of the public conversation focused on price, speculation and the possibility of making money quickly. Popoola found himself more interested in the technology’s underlying principles.
“It was not just about the money,” he says. “They were speaking about ownership, control and privacy.”
Blockchain proved more than just money – it was ideas
Those ideas resonated. Popoola describes himself as a private person who wants control over who can access his information. Blockchain presented a possible alternative to systems in which individuals surrender personal information without always understanding how it will be stored, shared or monetised.
He began writing about what he was learning, contributing to discussions and developing communities through platforms including Telegram. This was his route into Web3: research first, followed by writing, education and community participation.
At the same time, Popoola was pursuing a Bachelor of Business Administration at Bayero University in Kano. He had already developed experience in community building and worked as a press editor for a Nigerian education company serving schools and thousands of students. Rather than waiting until graduation to begin his career, he continued working alongside his studies.
Secret Network Foundation
His relationship with Secret Network began through Secret Agents, an ambassadorial programme operated by the Secret Network Foundation. He initially joined as an ambassador before progressing into responsibility for community activity in Nigeria and across Africa.
The work involved far more than maintaining online groups. Popoola helped organise events, supported local communities and represented privacy technology at conferences across the continent. His responsibilities expanded as Secret Network developed its African presence, eventually leading him into business development and partnerships.
This progression reflects one of Popoola’s defining characteristics. When presented with an opportunity, he looks for the work that needs to be done and begins doing it. Community activity became regional co-ordination; regional experience opened the door to business development; and his interest in privacy is now leading him towards financial-crime investigation and blockchain intelligence.
Popoola credits the leadership at Secret with giving him opportunities, resources and room to develop professionally. Working with an international organisation also demonstrated that a career in Web3 could be built from Nigeria and could extend well beyond geographical boundaries.
Blockchain in Africa
He believes blockchain is frequently understood differently in Africa than in Europe or the United States. For many Africans, the first attraction was financial. Cryptocurrency appeared to offer an opportunity to make money or to protect earnings in difficult economic conditions. That perception also helped create an environment in which speculation and misleading promises could flourish.
The picture is changing as useful applications become more visible. Stablecoins are one example. International payments through traditional financial systems can take several days to arrive, with delays and questions arising along the way. Stablecoins allow freelancers, contractors and businesses to receive cross-border payments much more quickly.
For someone working with international teams from Nigeria, this is a practical matter rather than an abstract debate about the future of finance. Faster settlement can determine when workers receive their salaries, when bills are paid and whether a business can operate smoothly.
Popoola believes African developers and entrepreneurs also have an important role in creating blockchain products that respond to local realities. Products developed without an understanding of African markets can miss the problems users actually need solved. Builders on the continent bring direct experience of payments, identity, access and financial exclusion.
Privacy remains central to his view of the industry. He rejects the suggestion that wanting privacy implies having something to conceal. In healthcare, finance, identity and commercial activity, people and organisations need to decide what information they share, when they share it and with whom.
Privacy
Blockchain’s transparency can create its own problems. A fully public transaction history may reveal information that an individual or business would never knowingly publish elsewhere. Popoola was drawn to Secret Network because its privacy-preserving smart contracts were designed to allow blockchain applications to protect sensitive information.
“Privacy is about having control over what you share and who you share it with,” he says.
He sees confidential technology as particularly important if blockchain is to move beyond early adopters. Institutions cannot place commercially sensitive information on systems where it is visible to everyone. Consumers will also require safeguards around financial, medical and identity data. Privacy therefore becomes an essential element of wider adoption.
Popoola’s next area of focus brings together several strands of his career. Since late 2025, he has been studying financial crime, compliance and the movement of illicit funds through digital-asset networks. He has also begun publishing analysis of major cryptocurrency thefts, including the work required to trace assets after an attack.
His interest sits at the intersection of two principles sometimes presented as incompatible. He wants individuals to retain legitimate privacy while ensuring that criminal organisations cannot exploit technology without scrutiny.
“I want privacy and I want compliance,” he says.
That distinction matters. Privacy tools can protect ordinary users, businesses and vulnerable people. Blockchain intelligence can identify patterns, follow illicit flows and help investigators understand how stolen assets move between wallets, exchanges and other services. Popoola wants to contribute to both sides of that equation.
His case for that contribution rests on the work already completed. He built communities while studying, helped extend a blockchain ecosystem across African markets, moved into commercial responsibilities and continued acquiring specialist knowledge as the industry changed.
Web3 careers are often presented as the product of fortunate timing or online visibility. Popoola’s career has been built through persistence. He entered the industry by asking why he had been paid in Bitcoin and stayed because he recognised ideas with implications for ownership, privacy and financial access.
The next chapter is likely to involve investigating the darker uses of the technology he once helped communities understand. The connection is logical. Popoola remains interested in the same underlying question: how can digital systems give people greater freedom and control while protecting them from those who would misuse that freedom?
For Popeblack, the answer lies in combining privacy, compliance and hard-earned knowledge of how blockchain is used in practice.
