This article explores leading enterprise blockchain solutions, citing global blockchain protocols that have powered Africa’s Web3 ascent. In addition, figuring out whether these decentralized networks fit the needs of your SME.
Understanding Blockchain Protocols: Foundations for Success
Blockchain protocols govern the decentralized world’s backbone, governing how transactions, data, and information are validated, stored and secured.
These systems are often divided into three main categories: permissioned(private), permissionless(public) and hybrid(blend of both). We’ll tackle the first two, given their in-depth roots in Africa.
Well-known decentralized networks like Ethereum and Bitcoin are classified as permissionless, meaning anyone can view data and participate within their community.
Permissioned are less known given their strict adherence to privacy and anonymity, hence chains like Hyperledger Fabric are served for the geeks and investors of Web3.
The main difference between these two types of blockchain protocols boils down to their consensus mechanism. In layman’s language, how transactions and dates are validated.

BNB Smart Chain
Binance’s BNB Smart Chain has also made a name for itself as a powerhouse blockchain protocol for African startups.
The decentralized network operates on a Proof-of-Staked Authority with 45 active validators, 21 Cabinets(highest staked amounts), and 24 Candidates.
With recent upgrades, increased block gas limit from 100 million per second to 200 million per second, BNB has achieved over 10,000 TPS.
Among various blockchain protocols,BNB is favoured due to its low transaction costs averaging between $0.03 and $0.1.
In addition, as an edge, BNB is an Ethereum Virtual Machine-compatible chain.
This means the network heavily benefits from familiar tooling, enabling seamless porting of Ethereum dApps.
Various tools include: Truffle/Hardhat, BSCScan explorer, MetaMask, BNB Chain SDKS, etc.
Binance has grown tremendously with its focus on the continent’s Web3 ecosystems. Binance Africa has trained over 1000 African developers, assimilating them or hosting their applications, i.e. Xend Fiance.
Cardano
Cardano, a popular among decentralized business networks, utilizes the Ouroboros Proof-of-Stake protocol.
The protocol can process more than 1000 TPS with popular projects like Leios, fostering a potential of 11,000 TPS.
Furthermore, it offers low transaction fees between $0.03 and $0.1.
