The Proof of Stake Alliance (POSA), a nonprofit industry alliance, has published two white papers examining on the status of deposit tokens in United States securities and tax law on Feb. 21. The papers were authored by representatives of over 10 industry groups.
Liquid staking is the practice on blockchains using a proof-of-stake consensus mechanism of issuing transferrable receipt tokens to show ownership of staked crypto assets or rewards accrued for staking. The tokens are often referred to as liquid staking derivatives, which is a term the POSA objected to as being inaccurate, recommending that they be called liquid staking tokens instead. Liquid staking has seen a surge of interest since the Ethereum Merge.
