11. The apparatus of claim 10, wherein the apparatus is further configured to:
acquiring first resource transfer information generated by a first account in a first time period;
generating a first key pair for the first resource transfer information, wherein the first key pair comprises a first private key and a first public key;
encrypting the first resource transfer information by using the first public key to obtain a first ciphertext;
sending a block creation request to a target blockchain node on a target blockchain, wherein the block creation request includes the first ciphertext, and the block creation request is used for requesting the target blockchain node to verify the first resource transfer information decrypted by the first ciphertext;
acquiring a first verification result sent by the target block chain node;
and under the condition that the first verification result indicates that the first resource transfer information passes verification, creating a first block on the target block chain, wherein the first block is recorded with the first ciphertext, the address of the created second block and a second private key, the second block is recorded with a second ciphertext, the second ciphertext is a ciphertext obtained by encrypting second resource transfer information by using a second public key corresponding to the second private key, the second resource transfer information is resource transfer information generated by the first account in a second time period, and the second time period is a previous time period of the first time period.
12. The apparatus of claim 11, wherein the apparatus is further configured to:
after the block creation request is sent to the target block chain node on the target block chain, the first cipher text is decrypted on the target block chain node by using the first private key, and the first resource transfer information is obtained;
and determining that the first verification result is that the first resource transfer information is verified to be passed under the condition that the target block chain node acquires the confirmation information of the first resource transfer information from the target equipment.
13. The apparatus of claim 11, wherein the apparatus is further configured to:
and under the condition that a first block is created on the target block chain, updating the latest block information corresponding to the first account in the target hash table from the address of the second block and the second private key to the address of the first block and the first private key.
14. A computer-readable storage medium comprising a stored program, wherein the program when executed performs the method of any of claims 1 to 9.
15. An electronic device comprising a memory and a processor, characterized in that the memory has stored therein a computer program, the processor being arranged to execute the method of any of claims 1 to 9 by means of the computer program.
