Embodiment Construction

[0049] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0050] Such as image 3 As shown, a group-based reconfigurable blockchain establishment method based on erasure codes includes the following steps:

[0051] S1. Add the new node to the blockchain system and choose whether to become a lightweight node. If it is, go to step S2, otherwise go to step S4;

[0052] In ordinary blockchains, when a new node joins the blockchain network, the complete block data must be downloaded f...

Abstract

The invention discloses a group reconfigurable blockchain establishment method based on an erasure code. Instead of storing block data, lightweight nodes store coded data slices. The blockchain system has complete functions, maintains the blockchain system architecture, and does not reduce the security of the system. The reconfigurable group proposed in the present invention can be deployed in a common blockchain system without affecting the architecture and functions of the system.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for establishing group reconfigurable block chains based on erasure codes. Background technique [0002] Blockchain technology, also known as distributed ledger technology, blockchain is gradually becoming known as the underlying technology of Bitcoin. Blockchain technology is not a single new technology, but the result of the fusion of various existing technologies. These technologies are skillfully combined with databases to jointly maintain a unique and reliable database through decentralization and trust, forming a new way of data recording, transmission, storage and expression. [0003] The core of blockchain technology is to ensure that all nodes in the entire system save and maintain the same tamper-proof database. It is an Internet distributed database technology. The storage of traditional data information is usually done through a centralized data center....
