商品期货交易委员会（CFTC）主席迈克·塞利格宣布“未来防护”计划，构建数字资产监管框架

The assessment is primarily based on a single, highly relevant, and moderately authoritative source that directly corroborates every element of the statement. The news article from 'The Block' explicitly reports that 'CFTC Chair Mike Selig unveils \'Future Proof\' initiative to upgrade crypto oversight,' aligning perfectly with the query.Furthermore, multiple other sources with varying levels of authority consistently confirm a key component of the statement: that Mike Selig is the CFTC Chair. This widespread corroboration of his role lends credibility to the overall context of the claim.There is no conflicting evidence among the provided sources. While the most authoritative source, the official CFTC website, does not mention the initiative in its summary, this is an absence of evidence rather than evidence of absence. A news outlet could be reporting on a recent speech or announcement not yet featured on the homepage. The encyclopedia entry from Britannica provides general background but is not specific enough to confirm or deny the claim.Given the direct, uncontradicted evidence from a specialized news source, supported by consistent confirmation of the individual's role from other sources, the statement is determined to be likely true with a high degree of confidence.
