The basic service module is deployed on all block link point devices and used for verifying the validity of a business request and recording the valid request after consensus is completed on storage, for new business requests, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation) on the new business requests, then encrypts the business information through a consensus algorithm (consensus management), transmits the encrypted business information to a shared account (network communication) and records and stores the business information, the intelligent contract module is responsible for issuing registration and triggering and contract execution, developers can define contract logic through a certain programming language, issues contract logic on the regional contract, issues contract configuration, executes the contract configuration according to other contract configuration, executes the operation of the contract chain, and simultaneously executes the monitoring of the running state of the contract, the monitoring of the operation of the key chain, the monitoring of the running state of the key, the operation of the key chain, the operation, the monitoring of the operation of the key chain, the operation of the key, the operation of the key, the operation of the.
The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use.
Block chains can be divided into private, federation, and public chains; here, the alliance chain is also called a community Block chain (Consortium Block chains), and refers to a Block chain whose consensus process is controlled by a preselected node. In the alliance chain, all or part of functions are opened only for the node members in the chain, and each block chain link point in the alliance chain can customize read-write permission, query permission and the like based on needs.
In the blockchain system, verification and confirmation of transactions can be completed in a short time through voting of special nodes, and transactions can be considered to be agreed by all nodes in the system if a plurality of nodes with irrelevant interests can agree.
The intelligent contract is characterized in that various contract terms can be embedded into hardware and software used by an attacker, so that the attacker needs great cost to attack, the intelligent contract jointly participates in customizing and is diffused and stored into a block chain by using a Peer-to-Peer network (Peer to Peer, P2P), and the intelligent contract constructed by the block chain is automatically executed under a trigger condition.

Alternatively, the voting data update request can default to a request for a single vote to the target candidate account when the voting function area can only vote a single time, and the voting data update request also includes the voting times of the th account when the voting function area can vote at least times a single time.
Illustratively, the voting data update request includes "00001, 00002, 01", where 00001 is the account id of account , 00002 is the account indication of the target candidate account, and 01 is the number of votes voted from account to the target candidate account.
In step 602, the blockchain system receives a voting data update request sent by the th client, where the voting data update request includes an account id of a target candidate account, and the target candidate account is a voting object in account .
Optionally, the voting data updating request is used to instruct the blockchain system to update the voting data of the target candidate account.

When receiving a voting data updating request, the block chain verifies the voting data, stores the voting data into a memory pool after the verification is completed, and updates a hash tree for recording the voting data; then, updating the update timestamp to be the time when the voting data update request is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can satisfy the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
the SHA256 is a characteristic value algorithm used for calculating a characteristic value, version (version number) is version information of a related block protocol in a block chain, prev _ hash is a block head characteristic value of a parent block of a current block, merkle _ root is a characteristic value of input information, ntime is update time of an update timestamp, nbits is calculation difficulty of the current block, is a fixed value within time periods and is determined again after the fixed time period is exceeded, x is a random number, and TARGET is a characteristic value threshold which can be determined according to nbits.
When the random number meeting the formula is obtained through calculation, the voting data can be correspondingly stored, a block head and a block subject are generated, a current block is obtained, then, other nodes in the block chain system check the newly generated block, and the newly generated block is added to the block chain stored in the block chain after the check is completed.
