Systems and methods of providing a multiple-operation transaction to a blockchain receive a plurality of related operations which collectively constitute a transaction between respective computing devices of a plurality of parties to the transaction, each of the plurality of related operations comprising a data set comprising: a value, a target, and a unique number; calculate a hash value using at least the plurality of related operations; and publish the hash value to a pool of unclaimed hash values; wherein, once a given operation of the plurality of operations is performed, the operation is published to a pool of unprocessed operations; and wherein at least one mining node is configured to sign the transaction into a block of the blockchain only if the at least one mining node has chosen, from the pool of unprocessed operations, a subset of operations whose hash value is identical to the unclaimed hash value.
