The terms "first" and "second" in this application are used for convenience of understanding only, and are not to be construed as sequential or limiting in any way.
For the purpose of facilitating understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
As shown in fig. 4, the blockchain system includes a first storage node and a first out-block node, the first storage node stores data through a local database, and the first out-block node is used for packing blocks and linking the blocks; the storage method is applied to the first storage node, and the first storage node comprises a first public key and a first private key.

S103, sending the first storage certificate of the self-media data to the terminal so as to inform the terminal that the self-media data of the user is stored by the block chain system.
In the above description, after the storage node stores the user self-media data, it directly returns a storage certificate to the user, and the storage certificate prompts the user that the storage operation of the user blockchain system is completed; the user does not need to wait, and can directly perform other operations; meanwhile, the block chain system can perform packaging uplink processing on the storage certificate, and other functions of the block chain system used by a user are not influenced; thereby improving the user experience of storing data on the blockchain system.
In one example, the self-media operation data comprises one or more of video data, text data, picture data and self-media time data of a user on an internet self-media platform.
In one example, the method further comprises: the first storage node randomly sends the user self-media data to a second storage node so that the second storage node backups and stores the user self-media data, the second storage node sends respective generated self-media data second storage certificates to the block-giving node, and the block-giving node links the user self-media data.
It should be noted that, if the number of the user self-media data is greater than the preset threshold, after the first storage node stores the user self-media data, the user self-media data may be divided into self-media data fragments, and the self-media data fragments are sent to a plurality of second storage nodes, where one self-media data fragment corresponds to one second storage node. The data with large data volume is fragmented, and fragmented backup storage is performed, so that the efficiency of data backup storage can be improved.
In addition, when a plurality of second storage nodes are selected, in order to ensure the availability of the backup storage function, the downtime rates of the plurality of second storage nodes can be multiplied to obtain a total downtime rate; and selecting a plurality of second storage nodes with the total downtime rate smaller than the preset downtime rate.

In one example, the method further comprises: the first storage node receives the integral mortgage operation of the terminal; allocating storage space authority to the terminal according to the integral number of the terminal; the storage space is the unit time storage space X storage time.
At this time, after the time of the self-media data required to be stored by the user is up, the storage node can delete the self-media data; in addition, the user does not have the used storage space authority, and the user can initiate a mortgage operation through the terminal to redeem the points corresponding to the remaining unused storage space authority.

It should be noted that, the ways of deducting the storage space authority include two ways: one is to directly deduct the storage space required by the user to operate the data from the media; one is to deduct the storage space right per unit time. The unit time may be one day, one week, or one month.
In one example, the method further comprises: the first storage node sends a user self-media data query request to the given block node, wherein the user self-media data query request comprises the self-media operation data ID; receiving first self-media operation data corresponding to the self-media operation data ID sent by the block-out node; and comparing a first hash value obtained by performing hash operation on the first self-media operation data with the hash value of the self-media operation, and if the first hash value is the same as the hash value of the self-media operation data, the first storage node confirms that the self-media operation data is linked up by the out-blocking node.

and if the first storage node does not receive the user self-media data first storage certification uplink response sent by the block-out node, sending a user self-media data first storage certification to the block-out node at intervals of a preset time period until the block-out node performs uplink transmission on the user self-media data first storage certification.
6. The device for storing internet self-media data on a block chain is characterized in that a block chain system comprises a first storage node and a first block outlet node, wherein the first storage node stores data through a local database, and the first block outlet node is used for packaging blocks and chaining the blocks; the storage device is applied to the first storage node, the first storage node comprises a first public key and a first private key, and the storage device comprises a receiving unit, a processing unit and a sending unit; wherein the content of the first and second substances,
the receiving unit is used for receiving a user self-media data uplink request sent by a terminal, wherein the user self-media data comprises self-media operation data, a self-media operation data ID, a user ID, a self-media operation data hash value, a signature of a terminal private key on the self-media operation data and a terminal public key of the user on an Internet self-media platform;
the processing unit stores the user self-media data through a local database and generates a first storage certificate of the self-media data; the self-media data first storage certificate comprises the user self-media data, a storage address, a signature of a first private key on the user self-media data and a first public key, so that the first storage node sends the self-media data first storage certificate to the block-giving node, and the block-giving node uplinks the user self-media data;
the sending unit sends the self-media data first storage certificate to the terminal so as to inform the terminal that the self-media data is stored by the block chain system.
7. The storage device of claim 6, wherein the self-media operation data comprises one or more of video data, text data, picture data and self-media time data of a user on an internet self-media platform.
8. The storage device of claim 6,
the sending unit sends the user self-media data to a second storage node randomly so that the second storage node backups and stores the user self-media data, the second storage node sends a second storage certificate of the self-media data generated by the second storage node to the block-giving node, and the block-giving node uplinks the user self-media data.
9. The storage device of claim 8, wherein the number M of second storage nodes is greater than or equal to 2, and M is a positive integer.
10. The storage device of claim 6,
if the first storage node does not receive the user self-media data first storage certificate uplink response sent by the out-block node, the processing unit sends the user self-media data first storage certificate to the out-block node at intervals of a predetermined time period until the out-block node uplinks the user self-media data first storage certificate.
