Crypto界网 March 5 News, according to Reuters, sources familiar with the matter revealed that regulatory agencies in the UK and the US have disagreements on how to test blockchain-based financial securities. The two sides announced the formation of a working group in September last year to reduce market entry barriers and strengthen digital asset cooperation, but at a meeting in January this year, the UK favored testing tokenized securities through a "sandbox," while the US SEC representatives expressed concerns, questioning its commercial viability and impact on innovation. The US is more inclined to adopt an "exemption relief" approach, which has received support from the US crypto industry. The two sides have reached broad consensus on goals such as coordinating stablecoin regulations, but disagreements remain on specific testing pathways. The working group is expected to submit a recommendation report before summer.
