According to Cointelegraph May 14th, the blockchain industry association POSA (The Proof of Stake Alliance) is in dialogue with the US Securities Commission (SEC) to discuss Staking-as-a-Service (STaaS) market supervision issues. POSA pre-certifies to the SEC that the use of the Proof-of-Stake (PoS) protocol is effective and scalable; and discusses its regulatory issues with the SEC, including requiring STaaS suppliers to avoid providing investment advice and avoid referring to financial industry terms (such as “,” Bonus “or” Return Rate “), and pay attention to network security, etc. Prior to August 2019, the POSA Association was an industry association composed of multiple blockchain projects. Its members include the Interchain Foundation and Blockfolio. The association is committed to providing education on blockchain technology to US lawmakers and regulatory agencies.
