Blockchain, arguably the most discussed and promising of FinTech trends, has incredible potential to transform legal technology. Infamous as the technology behind cryptocurrencies, distributed ledger technology (DLT) has developed far beyond these origins and may prove far more valuable than the currency it supports. As a form of DLT, blockchain allows for secure decentralisation of peer-to-peer, irreversible exchanges, providing a transparent and irrevocable record as these occur. The technology is already used across the legal industry and a plethora of opportunities to extend its application bubble beneath the surface, under development, waiting to break into the current market.
