Written by James Tylee, ex-algorithmic programmer Bloomberg. Dark pools, long used in traditional finance, are entering crypto whereby bringing stability but challenging decentralisation. By shielding trades from public view, they reduce slippage and protect against predatory strategies such as front-running. For institutions and whales, they unlock liquidity without destabilising markets. Yet this privacy clashes with blockchain’s ethos of transparency and raises regulatory concerns. But whilst dark pools could mature crypto markets, they risk reintroducing opacity and centralisation. Their impact will be pivotal: less a silver bullet than a sign of digital finance’s uneasy evolution.
