The invention provides a data delay publishing method and device and a storage medium, and the method comprises the steps: receiving a first delay publishing original transaction, and storing the original transaction into a transaction pool; when the original transaction can be packaged into a block, selecting public keys of a plurality of nodes to generate a secret key, and generating a Merkel root according to a bilinear mapping rule and each public key; encrypting the original text by using the secret key to generate a first ciphertext, and generating a delay publishing encrypted transaction according to the first ciphertext; replacing the original transaction with the encrypted transaction; replacing the original transaction with the encrypted transaction; respectively generating a data set of each selected node; respectively sending each data set to each corresponding node; and verifying whether the public key is matched and whether the Merkel root is the same when the verification transaction is executed, and restoring the secret key of the corresponding encrypted transaction when the verification is successful and the public key in each successfully executed verification transaction is enough to restore the secret key of the corresponding encrypted transaction. According to the invention, automatic delay of information publication is realized.
Description
Technical field [0001] This application relates to the field of blockchain technology, and specifically relates to a method, device and storage medium for delaying data publication. Background technique [0002] There is a certain demand in the society for the delayed publication of some information, such as the decryption of the detailed content of some papers, and some commercial information. You can publish some abstracts first to attract consumer demand. If you need to obtain detailed information, you need to pay or wait for a certain period of time. Free decryption for public welfare purposes; the existing delayed publication method is to encrypt the information that needs to be delayed to generate encrypted information, break up the encrypted information, and after a period of time, gradually record the scattered encrypted information to On the blockchain, users collect the scattered encrypted information and decrypt it to restore the information. In this mechanism, the re...
