The present invention relates to a block chain technology, and more particularly, to the field of block chain integral cross-chain sharing.
Background
Distributed trust and distributed ledger for blockchains can help to achieve transparent, public, non-tamperable, non-repudiatable, trusted points (also known as vouchers or tokens). Credible points are helpful for realizing commercial ecology based on point incentive.
Different business ecology, such as the ecology for production, supply and marketing of agricultural products and the ecology for health care industry of medical treatment, may have different requirements on the block chain network of the bottom layer in terms of security, privacy, performance trade-off and the like due to different participation parties and business characteristics, and thus may realize independent business ecology in different block chain networks. From the perspective of ecological convergence and incentive, the different business ecosystems (i.e., different blockchain networks) may have a requirement for realizing credible score sharing across chains to form a large cross-business ecology. Even in the same industry, due to different scales, regions and ownership, the system can be supported by a plurality of blockchain networks and has the requirement of realizing cross-chain integral sharing.
A blockchain network may carry multiple integrals (e.g., via ERC 20). Integration of different blockchain networks, unless indirectly achieved by a third party, such as a so-called point exchange platform. The indirect exchange cannot avoid the trouble that the same (large) ecology needs to maintain multiple points, has quite low efficiency, and is difficult to support commercial ecology to realize efficient point excitation and use scenes.
Direct integral sharing of a cross-block chain network without a third party is achieved, and multi-chain commercial ecology based on integral can be constructed in a boosting mode.

The invention introduces a cross-chain transfer-out intelligent contract and a cross-chain transfer-out state database module in an integral transfer-out chain, and introduces a cross-chain transfer-in intelligent contract and a cross-chain transfer-in state database module in an integral transfer-in chain. If a block chain network is used as both an exit chain support integral exit and a transfer chain support integral transfer, four modules of a cross-chain exit intelligent contract, a cross-chain exit state database, a cross-chain exit intelligent contract and a cross-chain exit state database are required to be deployed at the same time.
Different business ecology realized in different block chain networks may have the requirement of realizing credible score sharing to form cross-industry big ecology from the perspective of ecological integration and unified incentive. Even the same business ecology can be supported by a plurality of blockchain networks due to different scales, regions and ownership, and the requirement of cross-chain integral sharing is met.
Before the invention, a block chain network can simultaneously support and bear a plurality of points, and the two points can be exchanged through a third-party point exchange platform inside or outside the block chain network. But the same score cannot be trusted shared and transferred across blockchain networks without third parties, which is necessary for a business ecological support efficient score incentive and usage scenario composed of different blockchain networks.
First, the overall architecture.
The invention supports the realization of the credible score sharing (namely the credible coexistence of the same score on a plurality of block chain networks) and the score transfer of the cross-block chain network without a third party. As shown in FIG. 1, the present invention introduces a cross-chain roll-out intelligent contract (block 102) and a cross-chain roll-out status database module (block 103) in the credit roll-out chain (block 101), and a cross-chain roll-in intelligent contract (block 106) and a cross-chain roll-in status database (block 105) in the credit roll-out chain (block 104). If a block chain network is used as both an exit chain support integral exit and a transfer chain support integral transfer, four modules of a cross-chain exit intelligent contract, a cross-chain exit state database, a cross-chain exit intelligent contract and a cross-chain exit state database are required to be deployed at the same time.
And (4) configuring an authorized transfer-in chain list (each transfer-in chain is identified by a queriable unique identifier of the chain, such as a hash value of a founder block), wherein the list is maintained by the cross-chain transfer-out intelligent contract and is updated by an authorized updating party (given when the contract is initialized) set by a publisher of the cross-chain transfer-out intelligent contract.
The transfer chain can configure authorized transfer chain lists (each transfer chain is identified by a queriable unique identifier of the chain, such as a hash value of a founder block), and the lists are maintained by the cross-chain transfer intelligent contract and are updated by an authorized updating party (given when the contract is initialized) set by a publisher of the cross-chain transfer intelligent contract.
And the cross-chain roll-out intelligent contract is used for executing the roll-out transaction TX1 when the blocks are generated and verified on the roll-out chain, and recording a roll-out record into the cross-chain roll-out state database after the execution is successful. The cross-link roll-out transaction TX1 includes at least a roll-in link identifier, a roll-out credit, a roll-in recipient address, a roll-out specification, etc.
The cross-chain roll-out state database is a part of the roll-out chain world state and is used for recording the integral roll-out record and providing an on-demand query function.
And the cross-link transfer intelligent contract is used for executing the transfer transaction TX2 when the block generation and verification are carried out on the transfer link, and counting a transfer record into the cross-link transfer state database after the execution is successful. The cross-link forward transaction TX2 includes at least the corresponding forward transaction TX1, forward link id, forward link node(s), etc.
The cross-link transfer-in state database is a part of the transfer-in world state and is used for recording the integral transfer-in records and providing the function of inquiring according to needs.
For the same roll-out and roll-in chain pair, the TX1 on the roll-out chain and the TX2 on the roll-in chain completely correspond, and the total amount of the integrals transferred out of the roll-in chain on the roll-out chain is completely consistent with the total amount of the integrals received from the roll-out chain on the roll-in chain.
And II, performing a cross-chain process.
The credit owner (block 100) implements a cross-chain trusted transfer of its credit through an application, such as an APP, based on the following process:
(1) the credit owner (roll-out originator) submits a roll-out transaction TX1 to the roll-out chain (block 101) containing a roll-in chain identifier, a roll-out credit, a roll-in recipient address, a roll-out description, etc.;
(2) a cross-chain escape intelligent contract (block 102) for the escape chain (block 101), triggered to execute TX1 at block generation and validation: recording a roll-out record (information in TX 1) to a cross-chain roll-out state database, and deducting a roll-out amount from a point account of a point owner;
(3) the credit owner waits for the block where the roll-out transaction TX1 is located and x block transactions following the block are confirmed in the roll-out chain, so as to ensure that the block where TX1 is located is not rolled back and cancelled in the roll-out chain;
(4) the points owner submits a transfer-in transaction TX2 to the transfer-in chain (block 104), which includes a transfer-out transaction TX1, a transfer-out chain identification, and a transfer-out chain node(s);
(5) the branch-to-chain cross-chain branch-to-intelligent contract (block 106), triggered for execution at block generation and validation TX 2: selecting one or more out-link nodes from the listed out-link nodes, inquiring the blockchain nodes of the one or more out-links, and inquiring the execution status (success or failure, confirmation block of transaction account) of TX1 and the height of the current confirmation block of the out-link;
(6) if TX1 is false transaction, the local node in the transfer-in chain refuses the service for a certain time to the credit owner, and the initiator is prevented from carrying out denial-of-service attack on the transfer-in chain. If TX1 confirms no error in the out-link and accords with the transfer-in requirement of the transfer-in link, the cross-link transfer-in intelligent contract of the transfer-in link further counts the transfer-in records (information in TX2 and TX 1) into a cross-link transfer-in state database, and counts the residual amount into the address of the transfer-in receiver after deducting the transaction fee of TX 2;
and the cross-chain transfer-out state of the transfer-out chain and the cross-chain transfer-in state of the transfer-in chain cross-verify the same pair of transfer-out and transfer-in transactions (namely TX1 and TX 2) to realize credible cross-chain credit transfer and sharing.
