🇺🇸UPDATE: CFTC now lets US brokers invest customer funds in TOKENIZED assets and keep records on-chain. New staff guidance allows futures brokers and clearinghouses to put customer money into tokenized versions of approved investments, as long as the tokens carry the same legal rights. Exchanges, clearinghouses and swap dealers can use blockchains, including public ones, to meet recordkeeping rules, with no off-chain copy required. It comes two days after Chairman Mike Selig said US markets must prepare for "mass tokenization."
