Whereas the original proposal did not directly discuss digital assets, the reopening release is mainly focused on digital asset platforms.

On April 14, 2023, the Securities and Exchange Commission (SEC) issued a release amending portions of its earlier proposal to reinterpret the definition of an “exchange” and reopening the comment period for the proposed amendments (the Reopening Release.)
The SEC had issued a set of proposed amendments (the Original Proposal) on January 26, 2022, regarding the regulation of alternative trading systems (ATSs). The Original Proposal would amend Rule 3b-16 (Rule 3b-16) under the Securities Exchange Act of 1934 (the Exchange Act) to more expansively interpret certain terms used in the statutory definition of an “exchange” under Section 3(a)(1) of the Exchange Act. This reinterpretation would, among other things, cause the “exchange” definition to capture “Communication Protocol Systems”, which are not captured under the present version of Rule 3b-16.
