The invention discloses a distributed transaction processing system which comprises a computing layer, a storage layer and a scheduling layer. The computing layer is used for receiving an SQL request of a client, converting the SQL request into a KV read-write request, transmitting the KV read-write request to the storage layer, and initiating two-stage transaction submission based on the SQL request, wherein the storage layer is used for providing a read-write interface for two-stage transaction submission initiated by the calculation layer and providing storage service; and the scheduling layer is used for maintaining meta-information of the whole cluster, including KV data distribution information and the like, providing global time service for the computing layer and the storage layer, and storing distributed information submitted in two stages of transactions. When the transaction is submitted, the transaction is submitted through a two-stage submission protocol, and a multi-version concurrency control mechanism is adopted, so that mutual blocking of reading and writing is avoided.

The invention discloses a data processing method and device based on a block chain network and computer equipment, and the method comprises the steps that management equipment obtains a transaction request carrying transaction data and reference signature data, determines target endorsement equipment, and transmits the transaction request to the target endorsement equipment; when the transaction data and the reference signature data pass the verification, the target endorsement equipment determines a matching node device, acquires a signature key of the matching node device, determines to-be-signed data according to the transaction data, performs endorsement signature on the to-be-signed data by using the signature key of the matching node device to obtain endorsement signature data, and sends the endorsement signature data to the management device; and the management device generates a transaction block according to the endorsement signature data and the transaction data. According tothe embodiment of the invention, the time required for consensus can be effectively saved, so the transaction performance of the whole network is improved.

An automatic transaction apparatus communicates with a Web server and performs automatic transaction according to the operation of a user in order to perform automatic transaction processing with decreasing the number of times of requests to the Web server. Objects for each processing of the transaction processing are embedded in a screen content of a Web server, a part of the screen can be updated by an applet and script of the screen content, without downloading all the updates of the screen from the Web server. The screen can be updated without communication with the Web server. The transaction performance (speed) of the automatic transaction apparatus can be improved, and load of the Web server can be decreased.

The invention belongs to the technical field of off-chain payment center routing of a block chain, and discloses an off-chain payment center routing method and system based on a block chain, a mediumand equipment, and the method comprises the steps: each transaction in a payment channel network is segmented into a series of transaction units which are independently routed; a payment center selects an appropriate path to route the segmented transaction units; the payment center maintains a payment rate of a transaction unit in the network to maintain fund balance of the payment channel network; and the payment center performs congestion control on the flow of the transaction units in the network. To solve the problems of low network transaction performance, unbalanced channel fund flow, limited transaction amount of channel capacity and the like of the existing block chain payment channel network, a routing scheme of a payment channel center in the block chain payment channel network and a channel fund flow rate control technology are researched; transaction of a large amount of money can be executed in a low-capacity channel, and high transaction throughput is achieved on the premise that channel balance is not broken.

The invention relates to a rebalance strategy execution method for off-chain payment in a block chain, which improves the final effect of a rebalance strategy and can find out as many effective pathsas possible under the condition that the time complexity is slightly improved. On the basis of ensuring that the strategy is more fair and reasonable in the execution process, non-standard behaviors of some malicious nodes in the rebalance strategy are inhibited, and the benefits of honest nodes in the rebalance process are also maintained; and meanwhile, the fund offset problem in the blockchainpayment channel is relieved, and the availability of the payment channel is improved.
