The UK will bring cryptocurrencies, including Bitcoin, into a regulatory framework with legislation due by 2027.
The government says that firm and proportionate rules will give legal clarity over the sector's regulatory position.
It says they will also boost consumer confidence by ensuring consumers are robustly protected.
The changes mean that firms will need to be regulated by the Financial Conduct Authority in the same way as other providers of financial products – including being subject to established transparency standards.
Through this new regime the UK is helping to shape global standards for cryptoassets regulation.
The regime is designed to support responsible innovation, ensure open and competitive markets, and promote the UK as a destination of choice for digital asset businesses.
Chancellor of the Exchequer, Rachel Reeves MP, said:
'Bringing crypto into the regulatory perimeter is a crucial step in securing the UK's position as a world leading financial centre in the digital age.
'By giving firms clear rules of the road, we are providing the certainty they need to invest, innovate and create high skilled jobs here in the UK, while giving millions strong consumer protections, and locking dodgy actors out of the UK market.'
