Description
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a method and a system for generating a hash value and an address for a blockchain transaction, and a computer-readable storage medium.
Background
1. Block chain storage
Blockchains are a distributed ledger technique for recording transactions between two or more parties. The blockchain ledger acts as a decentralized database for maintaining detailed information for each transaction. These transactions are added to the ledger in chronological order and stored in the form of a set of data blocks. Each block references a preceding block to form an interconnected chain.
Ledgers are distributed across multiple nodes, with each node maintaining a complete copy. The blockchain automatically synchronizes and validates transactions on all nodes. The ledger is transparent to all participating members and can be checked by all members, thereby eliminating the need for a central authority or third party checking services.
As the number of blocks in the blockchain increases and the number of transactions stored in the blocks increases, the blockchain account is larger and larger, and as a node in the blockchain, it is necessary to prepare a large amount of storage and bandwidth, and the time for synchronizing the latest block in the blockchain system is longer and longer.
2. Block chain user address
Public keys (public keys for short) and private keys (private keys for short) are contents of asymmetric encryption algorithms in cryptography. As the name implies, the public key is made public, while the private key is kept secure. The private key is generated from a random seed, and the public key is derived from the private key through an algorithm. Since the public key is too long, an "address" appears for simplicity and practicality, and the address is derived from the public key. These deductions are one-way irreversible. I.e., the address cannot derive the public key, and the public key cannot derive the private key.
In the prior art, in a block chain system popular in the market, addresses are all generated by simply performing Keccak256 operation on public keys to generate 32-bit hash, and then 20 bytes are intercepted from the 32-bit hash to serve as a user address. The bit coin address is that base58 is carried out on 20 bytes and then a prefix is added, the Etheng directly carries out hexadecimal conversion on the 20 bytes, the total length of the generated address reaches 42 bits, the purpose that the address is difficult to repeat can be realized, however, the longer bit number occupies too much space capacity of a server, and in the actual using process, the transfer operation between users has huge risk because the address is unidentifiable (the transaction source can not be known through the address), if the transfer address is wrong, the users can not trace the source and check the mistake, and the transaction amount can be lost forever.
3. Block chain transaction hash
A hash function is a method of creating a small digital "fingerprint" from any kind of data. The hash function compresses a message or data into a digest so that the amount of data becomes small, fixing the format of the data. This function mixes the data in a hash, recreating a fingerprint called a hash value (hash sums, or hashes). The hash value is typically represented by a short string of random letters and numbers.
The transaction hash is to combine the main transaction information from, to, value, gas, etc. in the transaction structure and calculate a feature value with the same length, and the calculated hash length is 256 bits, that is, a 256-bit binary number is finally calculated no matter what the original content of the transaction. Moreover, it can be ensured that corresponding hashes are necessarily different as long as the original content is different.
The popular block chain system in the market, the trade hash is all simple carries out the Keccak256 operation back to information in the structure of trading, generate 32 bit hashes, change 32 bit hashes hexadecimal again, the trade hash length of generation is 64 bits, the trade hash that generates like this is in the in-service use process, because length can occupy a large amount of block chain storage space too greatly, and the trade hash degree of distinguishing is low, can't judge out the trade that is that chain through the trade hash, also do not be favorable to block chain historical data to file the back, quick inquiry retrieval transaction.
Therefore, there is a need to provide a method, a system and a computer-readable storage medium for generating a new hash value and address of blockchain transaction to solve the above technical problems.
