Abstract

Claims (24)

1 . A method for extracting and parsing Bitcoin transaction autonomy information, includes the following steps in sequence:

(1) building a Bitcoin client and synchronizing original block stream data to a local area, then parsing and structuring the original block stream data to obtain Bitcoin structured data, and then obtaining an output script of each transaction from the Bitcoin structured data;

(2) verifying a validity of the transaction output script by using a transaction script verification algorithm Algorithm test , and returning transaction autonomy information Tx information in response to determining failure to verify the validity of the transaction output script; and executing remaining steps, wherein the transaction autonomy information Tx information corresponds to online public opinion information; and

wherein obtaining the transaction autonomy information Tx information using the transaction script verification algorithm Algorithm test comprises:

( 201 ) converting the transaction output script Tx script out from a string format to a binary byte stream Scirpt bytearray ;

( 202 ) initializing an empty stack data structure;

( 203 ) reading a byte from the binary byte stream Scirpt bytearray ; and deleting the byte from the binary byte stream Scirpt bytearray ;

( 204 ) converting the byte into a Bitcoin operation code Op code;

( 205 ) putting the Bitcoin operation code OP code into a stack;

( 206 ) acquiring a stack top Bitcoin operation code OP code, and operating the stack according to the stack top Bitcoin operation code Op code;

( 207 ) in response to the stack top Bitcoin operation code Op code has subsequent input parameters, reading a corresponding number of bytes Bytes from the binary byte stream Scirpt bytearray ;

( 208 ) putting the number of bytes Bytes into the stack;

( 209 ) repeating ( 203 ) to ( 208 ) until the binary byte stream Scirpt bytearray is empty; and

( 210 ) verifying a stack top element; in response to the top stack element is a Boolean type True, determining that the transaction output script verification succeeds; in response to the top stack element is a Boolean type False, determining that the transaction output script verification fails; and in response to the top stack element is not a Boolean type, determining that it is the extracted transaction autonomy information Tx information , which will still be preserved on the blockchain, wherein corresponding unspent coins will be transferred to miners;

(3) extracting blockchain features from the transaction autonomy information Tx information , and then constructing a transaction autonomy information data table by using the transaction autonomy information and the blockchain features;

(4) sequentially reading the transaction autonomy information Tx in formation from the transaction autonomy information data table, and decoding the transaction autonomy information Tx information by using a transaction autonomy information decoding algorithm Algorithm code_recognition to obtain decoded information Information decode , and then inserting the decoded information Information decode into the transaction autonomy information data table as features;

(5) cleaning the decoded information Information decode by feature extraction and identification, marking decodable signs Sign decode of the decoded information Information decode which is successfully decoded as 1, and decodable signs Sign decode of other decoded information as 0, and inserting the decodable signs Sign decode into the transaction autonomy information data table as features;

(6) determining a fusion possibility of successfully decoded transaction autonomy information Information decode by using an information fusion algorithm Algorithm address_association based on transaction address association analysis, and fusing fusible transaction autonomy information Information decode to form fused information Information related ; and

(7) extracting an information ID info id before fusion from the fused information Information related, and constructing a transaction autonomy information fusion information data table,

wherein monitoring the online public opinion information on a blockchain is achieved.

2 . The method for extracting and parsing Bitcoin transaction autonomy information of claim 1 , wherein the step (1) of, building the Bitcoin client and synchronizing the original block stream data to the local area; then parsing and structuring the original block stream data to obtain the Bitcoin structured data; and then obtaining the output script of each transaction from the Bitcoin structured data, specifically comprises:

building a Bitcoin client Bitcoin Core, and synchronizing original block stream data Dt to the local area; parsing and structuring the original block stream data Dt to obtain Bitcoin structured data St, wherein the original block stream data Dt represent all block data of the Bitcoin system up to time t, and the Bitcoin structured data St are obtained by processing the block data before time t, including block size BTC_Block size and transaction list Tx_List; then, searching the transaction list Tx_List in the bitcoin structured data St to output a script field in array Outputs; and finally obtaining an output script of each transaction Tx script out .

3 . The method for extracting and parsing Bitcoin transaction autonomy information of claim 1 , wherein the step (3) of, extracting blockchain features from the transaction autonomy information Tx information , and then constructing a transaction autonomy information data table by using the transaction autonomy information and the blockchain features, specifically comprises:
