The EU's securities watchdog said that no specific EU rules are needed to regulate blockchain for the time being given the sector's still limited reach. However it noted that does not free up providers from complying with existing rules for safeguarding financial stability and orderly functioning of financial markets.
ESMA said it expects the early applications of blockchain, also known as distributed ledger technology or DLT, to focus on improving how existing trading infrastructure works. "Likely first areas of use may be less automated processes in low volume market segments and processes with minimum dependency on the existing legal framework," ESMA said.
