A system may facilitate distributed ledger technology (DLT) record based (for example, blockchain-based) voting. A node configured to support a voter role may access a DLT record to determine answersand/or parameters for a ballot. An organizer of the ballot may provide the voter with a voter token that confers vote- value to the voter. The voter may distribute the vote-value to the answers by using committed tokens that bind the voter to a particular vote-value without divulging the particular vote value while in a cryptographic form. The voter may distribute committed tokens to multiple answers. In some cases, the distribution of the committed tokens to multiple answers may frustrate attempts to determine the one or more targets to which the voter delivers a non-null vote-value. 一种系统可以促进基于分布式分类帐技术(DLT)记录的(例如，基于区块链的)表决。被配置为支持表决者角色的节点可以访问DLT记录以确定针对投票的答案和/或参数。投票的组织者可以向表决者提供表决者令牌，该表决者令牌向表决者授予表决值。表决者可以使用将表决者绑定到特定表决值的承诺令牌来将表决值分发给答案，而不会当在密码形式时泄漏特定表决值。表决者可以将承诺令牌分发给多个答案。在某些情况下，将承诺令牌分发给多个答案可能会挫败用于确定表决者向其交付非空表决值的一个或多个目
