Great Dyke Blockchain Technologies is a blockchain and artificial-intelligence software-development company operating across the UK and South Africa. It builds the digital infrastructure behind Barney’s other ventures — from asset-backed tokenisation (it powers the RWA layer for Kavai Precious Metals) to AI-driven products and supply-chain applications.
It is the most forward-leaning venture in the portfolio, connecting Barney’s computer-science roots to a clear thesis: the next wave of African enterprise will be digital-first. As CEO and Managing Investor, he pairs the engineering with the capital and commercial structure to take it to market.
