The blockchain revolution in Africa has come a long way since 2014, transforming from small meetups of five people to conferences hosting hundreds of participants across the continent. At the World Blockchain Summit, BitHub Africa Africa founder John Wainaina Karanja delivered a compelling keynote on how blockchain technology is reshaping Africa’s financial landscape.
From Startup Struggles to Blockchain Discovery
Karanja’s journey into blockchain began through necessity rather than curiosity. In 2014, he and his partner Chris were running Cloud Pesa, an M-commerce platform built on top of M-Pesa mobile money. Like many African startups, they faced significant challenges accessing capital and securing corporate partnerships.
“The startup life, especially in Kenya, is very hard,” Karanja explained. “Access to capital, access to resources, trying to get a meeting with a big corporate company for integrations – it’s a pain.” After three years of operations, Cloud Pesa ran out of money.
The discovery of Bitcoin at an AfterCoin conference became a pivotal moment. “When we saw Bitcoin, we were like ‘I wish we knew about this two months ago when we were still running the startup,’ because it was an interesting platform we could have leveraged to integrate payments onto our platform.”
BitHub Africa Africa’s Growth and Market Development
Since establishing BitHub Africa Africa, Karanja has witnessed tremendous growth in Bitcoin adoption across Kenya and the broader African continent. The numbers speak volumes about this expansion:
- Weekly Bitcoin trading volume on LocalBitcoins: approximately 100 million Kenyan shillings
- Events growing from 5-10 attendees to hundreds of participants
- Multiple blockchain events happening simultaneously across Kenya
However, this growth hasn’t been without challenges. The Central Bank of Kenya’s warning against cryptocurrencies has created difficulties for users wanting to buy and sell Bitcoin through traditional banking channels.
Government Support: A Competitive Advantage
One of Kenya’s unique advantages in the blockchain space is government support. Karanja highlighted the appointment of a chairman for the blockchain and AI task force by the President of Kenya as a significant milestone.
“I’ve had the opportunity to travel quite a bit to different conferences, and there’s a lot of progress and investment going into blockchain, but very few countries have government support,” he noted. “This is something we should leverage as a country.”
Understanding Money as a Language of Value
Karanja’s presentation delved deep into the fundamental concept of money, describing it as “a language to express value.” He traced the evolution from traditional forms of wealth expression to modern digital currencies:
Traditional Value Expression
In African communities, cattle have long served as a store of value and medium of exchange. “Most African communities consider cattle as wealth because you can use it to pay dowry,” Karanja explained, emphasizing how this represents a language for expressing value rather than reducing people to commodities.
The Digital Currency Evolution
The progression from commodity money (like salt in the Roman Empire) to virtual currencies (Bonga points, air miles) laid the groundwork for understanding cryptocurrencies. M-Pesa itself emerged when Safaricom discovered people were using airtime to exchange value and pay each other.
Bitcoin: The Internet of Value
Bitcoin represents what Karanja calls “the world’s first censorship-resistant peer-to-peer digital currency.” Its significance lies in enabling value transfer over networks without intermediaries like banks or central banks.
“If I have Bitcoin, I can send you Bitcoin without involving any intermediary,” he explained. “That is very powerful because it allows people to communicate money – remember, money is an expression of value – between each other in a peer-to-peer fashion.”
Four Key Characteristics of Successful Blockchain Platforms
According to Karanja, any useful blockchain platform must have these elements:
- Protocol: Mathematical rules governing operations (Bitcoin is “regulated by mathematics”)
- Blockchain: Distributed, immutable ledger secured by miners
- Currency: Digital tokens for transactions and miner rewards
- Software: Open-source code enabling innovation and development
Open Innovation and Global Market Access
The open-source nature of Bitcoin creates unprecedented opportunities for African entrepreneurs. “Today any one of you can take an idea to market at the global level through using Bitcoin and cryptocurrencies and blockchain,” Karanja emphasized. “You do not need permission from any gatekeeper to transact or integrate your application.”
This permissionless innovation model contrasts sharply with traditional financial systems that often exclude African startups from global markets due to regulatory and infrastructure barriers.
Kenya’s Path to Becoming a Blockchain Hub
Karanja envisions Kenya joining the ranks of major blockchain hubs like Dubai, Zurich, and Berlin. The country’s advantages include:
- First-mover experience with mobile money (M-Pesa)
- Growing developer community and tech ecosystem
- Government support for blockchain initiatives
- Strong mobile penetration and digital payment adoption
“We are the first people to develop digital currency on the mobile phone with M-Pesa,” he argued. “So we should also be among the first people to adopt this technology and use it for different solutions.”
Key Takeaways
- Africa’s blockchain ecosystem has grown exponentially since 2014, with Kenya leading adoption
- Government support gives Kenya a competitive advantage over other blockchain markets
- Bitcoin enables censorship-resistant, peer-to-peer value transfer without intermediaries
- Open-source blockchain technology allows African entrepreneurs to access global markets
- M-Pesa’s success positions Kenya well for cryptocurrency and blockchain adoption
- Weekly Bitcoin trading volumes in Kenya exceed 100 million shillings
The Future of Blockchain in Africa
As blockchain technology matures, its applications extend beyond payments into agriculture, healthcare, and business empowerment. The World Blockchain Summit agenda reflected this diversity, covering crypto wealth management, blockchain’s social economic impact, and practical business applications.
The challenge now lies in scaling these applications while navigating regulatory uncertainties and building sustainable ecosystems. With government backing and a growing community of developers and entrepreneurs, Kenya is well-positioned to lead Africa’s blockchain revolution.
