Judge Rakoff puts the Ripple Party on Ice as the Crypto Community and SEC Ponder their Next Moves

Just barely two weeks ago, we wrote about the half-victory for Ripple Labs in its ongoing litigation with the Securities and Exchange Commission (“SEC”), in which Judge Analisa Torres granted partial summary judgment in favor of Ripple on the issue of whether certain sales of Ripple’s XRP cryptocurrency tokens were “securities” under the federal securities laws. Some in the crypto industry interpreted her ruling to mean that secondary transactions in crypto assets on centralized and decentralized crypto exchanges were not transactions in “securities,” even though Judge Torres expressly declined to address the secondary trading issue. Fast forward to today, and a new ruling out of the SDNY against Terraform Labs casts further doubt on this interpretation.

The Rise of Whistleblower Tips (and Rewards) for Crypto Sleuths
February 17, 2023 | Blog | By Cory S. Flashner, Edmund P. Daley
Whistleblowers are often thought of as public company insiders who report alleged wrongdoing like insider trading, market manipulation, submitting false or misleading company disclosures or other securities and commodities law violations. The emergence of the digital asset industry, and the expanding number of crypto companies using public-facing blockchains, has changed this paradigm. Now anyone with the time, skill, and inclination can audit every transaction on a public blockchain, and the concept of the “traditional” whistleblower has greatly expanded in this relatively unregulated space.
