Description
Technical Field
The invention relates to the technical field of blockchains, in particular to a main sub-chain running state collection method of a blockchain, a system and a storage medium applying the method.
Background
The conventional blockchain is a single chain structure, and each common node in the blockchain stores all states, serially executes all transactions, and agrees with all other machines. Once the main network is on line, only minor repair can be performed, and the main network cannot be upgraded in a large range. In terms of blockchain technology, security and performance on the same chain are contradictory. However, the task of blockchain is various, the transfer of digital currency Token has very high security requirement, but the asset proving business is less sensitive to security, more important to efficiency, and is difficult to consider on one chain, even the later side chain technology has little use for relieving the pressure of the main chain (the side chain is an interface of the main chain, and develops a blockchain project suitable for the technical requirement or the self function, but the side chain must possess the computing power equivalent to the main chain to ensure the security of the side chain currency, so that the computing power requirement is relatively high, and the security has hidden trouble).
In order to solve the above-mentioned problems, a dual-layer architecture of a main chain and sub-chains is proposed, and each sub-chain directly processes data such as transaction, contract, etc. independently according to business characteristics and requirements, and is not dependent on the main chain in the hierarchy. These sub-chains, which are identical in structure but differ in the number of calling nodes and in function, are referred to as "isomorphic chains". The mechanism ensures that the main chain is only responsible for the most important transaction, only the most critical data is recorded on the main chain, and daily transactions and transactions independently exist on the sub-chain, so that the safety and the efficiency can be considered.
Because the main chain is often endowed with responsibility for monitoring the whole network, but data isolation exists between the main chain and the sub-chain, no direct data channel exists generally, and how to monitor the running state of the sub-chain is a technical problem to be solved urgently at present.

the current sub-chain participation organization submits the state data by calling a state collection intelligent contract of the main chain, and the main chain broadcasts the collected state data of the current sub-chain organization to a blockchain network; other sub-chain participating organizations acquire the state data by listening to the state collection intelligence contract of the backbone.
Preferably, the state data of the sub-chain includes: the sub-chain participation organization quantity and change information, the number of sub-chain link points and change information, the sub-chain running state, the sub-chain intelligent contract quantity and change information.

Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear and obvious, the invention is further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention discloses a main sub-chain running state collection method of a block chain, which comprises the following steps of:
constructing a coalition chain network, wherein the coalition chain network comprises a main chain and more than one sub-chain;
a state collection intelligent contract is deployed on the main chain, and the state collection intelligent contract is used for collecting state data of the sub-chain;
the sub-chain participation organization owns write rights to the state collection intelligent contract on the main chain;
the current sub-chain participation organization submits the state data by calling a state collection intelligent contract of the main chain, and the main chain broadcasts the collected state data of the current sub-chain organization to a blockchain network; other sub-chain participating organizations acquire the state data by listening to the state collection intelligence contract of the backbone.
In this embodiment, the sub-chain may be a distributed file system sub-chain, or an industry sub-chain of multiple application fields, or a cross-chain sub-chain of multiple external blockchain networks, etc. The state data of the sub-chain includes: the sub-chain participation organization quantity and change information, the number of sub-chain link points and change information, the sub-chain running state, the sub-chain intelligent contract quantity and change information. The operating state includes block height, transaction number, tps statistics, etc.
The sub-chain participation organization has read-write authority on the state collection intelligent contract; when the sub-chain participation organization writes an event to the state collection intelligent contract, the state collection intelligent contract sends a notification; the sub-chain participating organization monitors the state of the main chain to collect the notification sent by the intelligent contract, and acquires the state data of the sub-chain contained in the notification.
Further, when the new sub-link intelligent contract is deployed by the sub-link, submitting a transaction to the state collection intelligent contract of the main chain through the current sub-link participation organization; the state collection intelligence contract of the backbone broadcasts change information of the sub-chain intelligence contract to a blockchain network. After the other sub-chain participation organizations receive the broadcast, the broadcast content and the fact information are further analyzed and compared, and the situation that the analysis and comparison results are inconsistent is responded. In this embodiment, when a new smart contract is deployed by a sub-chain, an organization (e.g., a deployer) on the sub-chain may make the event (i.e., the sub-chain deploys the new smart contract) known to the main chain by calling the state collection smart contract on the main chain. Invoking the state collection intelligent contract triggers the state collection intelligent contract of the main chain to send out a notification (notification content: a new intelligent contract and information of the contract are deployed on a certain sub-chain), all participating organizations on the sub-chain can receive the notification, so that other participating organizations (i.e. participating organizations on the sub-chain which are not invoking the main chain contract) can check whether the notification is true or not according to the notification content, and information submitted to the main chain by a caller is prevented from being wrong. If not, a chain down arbitration or the like may be initiated.
The sub-chain participating organization has write rights to the state collection intelligent contract. The state collection smart contracts are deployed on the backbone such that the state collection smart contracts are able to collect and record various state data for each sub-chain.
The sub-chain participates in the organization to automatically collect various information of the sub-chain at regular time, when the information is changed (the initial state submitted for the first time also calculates the state change, namely, the state is not changed, for example, the node list is changed, the running state is changed, and the like, all calculate the change), the new state is submitted to the state collection intelligent contract of the main chain through the monitoring account number with the main chain contract submitting authority.
The organization on the main chain collects events sent by the intelligent contract through monitoring the states, acquires various state data, knows state change information and can read the latest state.
Other participating organizations on the sub-chain can monitor events sent by the state collection intelligent contract on the main chain, compare and analyze the monitored state data with sub-chain information collected by the participating organizations, and if the monitored state data is inconsistent with the sub-chain information, complaints can be initiated under the chain. Because the alliance chain is of a real-name system, the under-chain treatment is feasible, the efficiency is high, the cost is low, and the method is a preferable treatment scheme.
An embodiment of the present invention further provides a main sub-chain running state collection system of a blockchain, which includes a memory and a processor, where the memory stores instructions, and the processor executes the instructions stored in the memory to cause the system to implement the running state collection method according to any one of the above.
