A computer-implemented method to participate in a token transfer process for transferring a first quantity of token from a sender node to a recipient node using a blockchain is disclosed. The token transfer process includes a plurality of participating nodes and execution of a set of indirect token transactions between multiple pairs of the participating nodes. The method is implemented at a participating node performing steps of obtaining a subset of the indirect token transactions for which the participating node is either an input node or an output node, collaborating with a respective second participating node included in each indirect token transaction of the subset to generate a commitment channel for the indirect token transaction between the participating node and a second participating node, and collaborating with all other participating nodes in executing the indirect token transactions of the subset using the generated commitment channels.
