Imagine verifying land title deeds or sending school fees from the diaspora instantly. Envision a world where every transaction, record, and agreement is tamper-proof, transparent, and instantly verifiable—without needing a central authority. This isn’t science fiction; it’s the foundational promise of blockchain technology in Kenya.
What is a blockchain?
A blockchain is a shared immutable ledger enabling the record of transaction and tracking of digital assets within a business network. A blockchain database stores data in blocks which are then linked together in a chain. The data is chronologically consistent because you cannot modify or delete data without the consensus of the network. Blockchains are fundamental to cryptocurrencies, ensuring secure and verifiable transactions. They can be used to make data in any industry immutable meaning the data cannot be altered with.
Unlike traditional databases, blockchains are managed by a network of computers (nodes) that validate and record transactions. No individual or organization controls the data. The key benefit of blockchain technology in Kenya lies in its ability to enhance transparency, security, and trust, especially in areas traditionally dominated by intermediaries like banks and brokers. It holds promise for sectors like land registry, health records, and mobile payments. They also help in improving efficiency and cost by enhancing accountability.
The evolution of blockchain
Blockchain technology began with the introduction of bitcoin in 2008, by Satoshi Nakamoto. The blockchain served as a ledger, safeguarding transactions and securing records, a key issue in digital currency at that time. With the development of other currencies like Ethereum in 2015, blockchain started to support smart contracts and this broadened real-world application of blockchain. It extended in use for areas like finance, health and the voting system. With time blockchain has grown beyond cryptocurrency and is becoming a key player in decentralised finance (DeFi) and non-fungible tokens (NFTs). Blockchains continue to evolve with technologies such as Artificial intelligence (AI) and the Internet of Things (IoT).
Blockchain technology in Kenya has evolved rapidly from early experimentation with cryptocurrencies around 2014 to becoming a key driver of innovation across multiple sectors today. Initially embraced by fintech startups inspired by the success of mobile money platforms like M-Pesa, blockchain technology in Kenya has expanded its applications to include cross-border payments, supply chain transparency, land registry and digital identity solutions.
Between 2017 and 2020, the country saw a surge in blockchain startups and pilot projects, which sparked growing interest from financial institutions and regulators. More recently, both the government and private sector have collaborated on blockchain technology in Kenya initiatives aligned with the nation’s Vision 2030, aiming to harness the technology for economic growth and improved governance in the country. Despite some challenges such as regulatory uncertainty and infrastructure gaps, blockchain technology in Kenya continues to develop a vibrant ecosystem driven by a young, tech-savvy population,digital literacy and increasing digital connectivity.
How it works
Blockchain technology records data by lining data blocks together. Each block contains crucial information about the movement of digital assets. Here is a more detailed explanation of how it works.
1) Record transactions
Each transaction made is recorded as a block and it shows the movement of physical or digital assets from one party to another in a blockchain network. Each block contains a timestamp which records the exact time each transaction took place. The timestamp ensures that the transaction took place chronologically. The details recorded here include
- Who was involved in the transaction.
- Where did the transaction occur.
- When did the transaction occur.
- What happened during the transaction.
- Why did the transaction occur.
- How much of the assets was exchanged.
- How many pre-conditions were met during the transaction
2) Gain consensus
Most participants in the blockchain must agree that the transaction record is valid. Rules of agreement can vary depending on the type of network but are mostly established at the start of the network. The rules of agreement are called consensus mechanisms.
Two common consensus mechanisms are:
i) Proof of Work (PoW): (Used by Bitcoin) Nodes (called “miners”) compete to solve complex cryptographic puzzles. The first one to solve it gets to add the new block to the chain and is rewarded. This “work” makes it computationally expensive and difficult to manipulate the network. This process is energy-intensive, making it difficult and costly to attack or manipulate the network.
ii) Proof of Stake (PoS): (Used by Ethereum 2.0) Validators are chosen to create new blocks based on the amount of cryptocurrency they “stake” (hold as collateral) in the network. This incentivizes honest behaviour.
3) Linking the blocks together
Each block is linked to the previous block and the other after it. This creates a secure chain of data. This is done through cryptographic hashes are appended to the new block acting as a chain that links blocks together. If the block’s content changes intentionally or unintentionally, the hash value changes providing a way to detect data tampering and malicious actions could result in the loss of staked funds.
4) Building an irreversible blockchain
The blocks are grouped together in an irreversible chain known as blockchain; each additional block strengthens the previous block and therefore strengthens the whole blockchain. This makes the blockchain secure from malicious actors who may try to insert fraudulent transactions into the chain.
5) Upholding trust, transparency and immutability
The immutability provides a transparent and trusted ledger that all participants can rely on to secure the transactions preventing fraud and transactions that cannot be changed.
6) Share the ledger
All participants receive the latest copy of the central ledger from the system.
Types of blockchain network
There are four main types of distributed networks in the blockchain. They include
i) Public blockchain network
These are open and permissionless blockchain networks, meaning it allows anyone to join. Examples of these are Bitcoin, Ethereum and Litecoin blockchain. All participants have equal rights to read, edit and validate the blockchain. However , it also comes with drawbacks which includes high computational power requirements, lack of transaction privacy and potential weaker security.
ii) Private blockchain network
Also called managed blockchain, they are permissioned and restricted, typically used within an organisation or by selected participants. A single organization governs the entire network controlling who is allowed to participate and what rights they have in the blockchain. Private blockchain networks are partially decentralised because they have access restrictions. It can be run behind a corporate firewall and be hosted on premises. A Good example of this blockchain is Ripple, a digital currency exchange network.
iii) Hybrid blockchain network
These blockchain combine the elements of both public and private blockchain allowing selective transparency and customizable access level. In This way they control access to specific data stored in the blockchain while keeping the rest of the data out to the public.
iv) Consortium blockchain network
This is a semi-decentralized blockchain governed by a group of organizations who share the responsibility of maintaining the blockchain. The control who can submit transactions and access data. Organizations who share a common goal can benefit from this type of blockchain. Examples of such organizations that use blockchain technology in Kenya are the energy sector and the shipping industry.
Blockchain protocols and platforms
The term blockchain protocol refers to a set of rules that govern how data is received, shared and stored within a blockchain network. Each protocol defines how participants reach consensus, how transactions are validated and how security is maintained. Here’s a list of common blockchain protocols and platforms:
- Hyperledger Fabric
- Ethereum
- Quorum
- Corda
-
Hyperledger fabric
Hyperledger Fabric, an open-source project by the Linux Foundation, offers a modular architecture ideal for enterprise blockchain applications. It supports use cases such as supply chain traceability, trade finance, and digital identity verification.
