Problems solved by technology

At the same time, this architecture will also lead to excessive load on the super nodes, resulting in the problems that the quality of service cannot be improved and a single point of failure
[0006] (2) It is difficult to realize the nearby download function
According to the design, some user devices of the blockchain system will store the latest blockchain of the current system, and when new user devices request to obtain the blockchain, they will return corresponding data, but how to enable new user devices to Obtaining the blockchain from the nearest user device that stores the latest blockchain has always been a problem in the blockchain based on the TCP / IP network architecture

Abstract

The invention discloses a blockchain synchronization method and device based on NDN (Named Data Networking), and belongs to the technical field of communication. The method comprises the steps that: user equipment sends a blockchain synchronization request packet to a network node, wherein a name of the blockchain synchronization request packet comprises a NDN protocol identifier, an application identifier, a request packet type and state information of a blockchain, and the state information of the blockchain is used for indicating a height of a block with the maximum height in the blockchain stored by the user equipment; and receiving a synchronous data packet returned by the network node, and extracting a block in the synchronous data packet to store into a blockchain database. The synchronization method is a blockchain system communication implementation method based on the NDN, and can reduce network communication traffic, reduce transmission delay and improve data transmission efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a block chain synchronization method and device based on Named Data Networking (NDN). Background technique [0002] The blockchain system is a decentralized, immutable shared distributed intelligent database. The blockchain was first born in Bitcoin. It is a chained data structure composed of blocks connected in sequence in chronological order, providing technical support for the Bitcoin system. Wherein, each block is also a data block, and each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. [0003] In the blockchain system, after the user equipment produces a new block, it broadcasts the block. After receiving the block, other user devices in the network will verify its legitimacy; if the verification is passed, the user device will ...
