In the early hours of September 15, Ethereum completed "The Merge – the long-awaited transition from its original proof-of-work consensus mechanism to proof-of-stake.

Later that day, SEC Chairman Gary Gensler pointed to the staking mechanism as a signal that an asset might be a security as determined by the Howey test.
