Method for initiating the storing of a hashed data item in a distributed ledger database, wherein the distributed ledger database is managed by a computer network, the computer network comprising a plurality of nodes, wherein the method comprises at least the steps of: • initiating, by a first computing device, the generating of an encrypted data item, wherein the encrypted data item is an encryption of a second data item, the second data item comprising a first data item, the first data item encoding information indicative of a task to be performed; • initiating, by the first computing device, the generating of the hashed data item, wherein the hashed data item is a hash of a third data item, the third data item comprising the first data item; • initiating, by the first computing device, the providing of first information and of the encrypted data item to a second computing device, wherein the first information characterizes the first data item by including information that allows for identifying the first data item or determining the information encoded in the first data item and the second computing device is configured to initiate the decryption of the encrypted data item, whereby the second computing device is made aware of the task before storing of the hashed data item in the distributed ledger database and may perform the task before the storing of the hashed data item in the distributed ledger database; and • initiating, by the first computing device, the providing of second information and of the hashed data item to a first node of the computer network, thereby initiating the storing of the hashed data item in the distributed ledger database, wherein the second information characterizes the first data item by including information that allows for identifying the first data item or determining the information encoded in the first data item. • initiating, by a first computing device, the generating of an encrypted data item, wherein the encrypted data item is an encryption of a second data item, the second data item comprising a first data item, the first data item encoding information indicative of a task to be performed; • initiating, by the first computing device, the generating of the hashed data item, wherein the hashed data item is a hash of a third data item, the third data item comprising the first data item; • initiating, by the first computing device, the providing of first information and of the encrypted data item to a second computing device, wherein the first information characterizes the first data item by including information that allows for identifying the first data item or determining the information encoded in the first data item and the second computing device is configured to initiate the decryption of the encrypted data item, whereby the second computing device is made aware of the task before storing of the hashed data item in the distributed ledger database and may perform the task before the storing of the hashed data item in the distributed ledger database; and • initiating, by the first computing device, the providing of second information and of the hashed data item to a first node of the computer network, thereby initiating the storing of the hashed data item in the distributed ledger database, wherein the second information characterizes the first data item by including information that allows for identifying the first data item or determining the information encoded in the first data item.
