acquiring an executable code of the application program according to the downloading address information of the application program;
detecting the security reliability of the application program by establishing a simulation environment and running an executable code of the application program;
if the security reliability of the application program passes the detection, writing the related information of the application program into the latest block in the block chain network;
synchronizing a blockchain ledger to other accounting nodes in the blockchain network, wherein the blockchain ledger comprises the latest block, and when the other accounting nodes successfully verify the latest block, executable codes of the application program can be downloaded and used by user nodes in the blockchain network;
wherein the accounting node, the application publishing node and the user node are nodes in the blockchain network.
7. An accounting node as claimed in claim 6, wherein the information about the applications broadcast by the application publishing node in the blockchain network comprises:
and the application program publishing node adopts the private key of the application program publishing node to sign the relevant information of the application program.
8. A user node, comprising:
a memory;
a processor;
a communication interface; and
a computer program;
wherein the computer program is stored in the memory and configured to be executed by the processor to:
acquiring relevant information of an application program from a blockchain account book, wherein the relevant information comprises identification information of the application program, a hash value of an executable code of the application program and download address information of the application program;
acquiring an executable code of the application program according to the downloading address information of the application program;
calculating a hash value of executable code of the application program;
if the hash value of the executable code of the application program calculated by the processor is consistent with the hash value of the executable code of the application program recorded in the blockchain account book, determining that the executable code of the application program is not tampered.
9. The user node of claim 8, wherein the processor, when computing the hash value of the executable code of the application program, is specifically configured to:
the processor calculates a hash value of the executable code of the application program before running the executable code of the application program.
10. The user node according to claim 8 or 9, wherein the processor, when obtaining the information related to the application from the blockchain ledger, is specifically configured to:
if the block chain network has a preset number of blocks generated after the application program publishing node broadcasts the relevant information of the application program in the block chain network, the relevant information of the application program is obtained from the block chain book.
11. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the method according to any one of claims 1-5.
