Methods and systems for token-based out-of-chain mutual authorization are disclosed. The hub computer may maintain a network of out-of-chain (or "layer-2") channels between itself, the cryptocurrency issuer computer, and the cryptocurrency custody computer. The out-of-chain channels correspond to one or more underlying block chains. The hub computer may receive an access token, a resource provider identifier, and an interaction value. The hub computer may use the access token to identify a cryptocurrency issuer computer associated with the mobile device and use the resource provider identifier to identify a cryptocurrency keeper computer associated with the access device. The hub computer may update the state of the out-of-chain channels corresponding to the two computers based on the interaction value, and then send an authorization response message. 公开了用于基于令牌的链外交互授权的方法和系统。中枢计算机可以在其自身、加密货币发行方计算机和加密货币保管方计算机之间维护链外(或"二层")信道的网络。这些链外信道与一个或多个底层区块链相对应。中枢计算机可以接收访问令牌、资源提供方标识符和交互值。中枢计算机可以使用访问令牌来识别与移动装置相关联的加密货币发行方计算机，并
