Problems solved by technology

However, due to the random witness mechanism, each piece of data is only stored by the ledgers of some nodes in the system, and whether the ledgers of each node storing data is safe and reliable cannot be confirmed. At present, the data stored in ledgers based on random witnesses is easy to be tampered with. less secure

Embodiment Construction

[0089] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0090] Features of big data certificate storage service scenarios:

[0091] In the big data environment, the total amount of data is large, the data types are multiple, and the generation speed is extremely fast. Therefore, the distributed ledger in the big data environment should have: high throughput and scalability. Data storage refers to storing electronic data in the server in the form of backup. In other words, using distributed ledgers to maintain a linearly growing...

Abstract

The present application provides a method and device for creating a schematic ledger based on random witness, and relates to the technical field of distributed ledgers. Applied to a distributed ledger system; the distributed ledger system includes a single chain of global knowledge maintained by committee nodes, and a DAG structure maintained by committee nodes and ordinary nodes. It aims to provide a ledger method based on verifiable basic ledger information, so that the graph ledger of the DAG structure of each node in the distributed ledger is reliable, combined with the global knowledge based on the writing of the graph ledger Blocks are randomly witnessed to ensure that the blocks written into the schematic ledger are safe, thereby ensuring the security of the distributed ledger that is randomly witnessed.

Description

technical field [0001] The present application relates to the technical field of distributed ledgers, in particular to a random witness-based schema ledger creation method and device. Background technique [0002] In 2008, an anonymous person who claimed to be Satoshi Nakamoto proposed Bitcoin (Bitcoin), and then, distributed ledger technology (distributed ledger technology) based on blockchain technology came out one after another. Distributed ledger technology is essentially a database that shares assets across multiple sites, geographic locations, or institutions. Distributed ledger technology has gradually attracted widespread attention and application due to its characteristics of decentralization, trustlessness and tamper resistance. [0003] The first-generation blockchain technology represented by Bitcoin mainly uses node state machine replication, that is, all nodes in the entire network agree on instructions and data, but the data transmission process of complete ...
