IEEE Std 2140.5-2020 pdf download – IEEE Standard for a Custodian Framework of Cryptocurrency
1. Overview Asset custody mainly refers to custody services provided by third-party banks or securities firms in the financial and investment fields. For example, traditional equity investments or securities investment funds shall designate banks as third-party custodian institutions to complete fundraising to ensure that investors raise funds. The funds raised by investors are segregated from the funds owned by the fund management firm, and are held in custody by a fair third party, so as to avoid any theft or confusion. Asset custody is a functional module of asset management and needs to meet the needs of asset escrow. 1.1 Scope This standard defines a standard framework of a custodian service for cryptocurrency and digital assets. The framework includes a custodian reference technical architecture, business logic description, custodian service business models, digital asset evaluation criteria, operational procedure models, and regulatory requirement support models. 1.2 Purpose There are no agreed frameworks for custodian services in token assets and cryptocurrency. This standard aims to provide a custodian framework with regulation, cryptocurrency processing and management in custody, and a reference technical architecture to support the framework.
