Constructive Approximation

A CNXT 1-of-1 edition of Constructive Approximation, a real organization record from the Crossref journal registry (ISSN ISSN 0176-4276). Registry identity is verbatim from the source registry's public data; token attributes are CNXT-issued indicative values. The edition's web+usd:// address doubles as its settlement rail on the CNXT network — reserved, with no holder or balance, until the edition is minted. Opens the CNXT-native interface, not a third-party site. CNXT is not affiliated with Crossref journal registry or Constructive Approximation.
