Embodiment Construction

[0034] In the early days of the development of blockchain technology, users basically added their own PCs and laptops to the blockchain network to become blockchain nodes in the blockchain network. At this time, it can be called the era of the 1.0 architecture of the blockchain network. Not only is the behavior of joining the blockchain network an autonomous behavior of the user, but the user also needs to operate and maintain independently, such as the PC and other devices that have joined the blockchain network. maintenance and configuration etc. With the continuous development of blockchain technology, especially the increasing demand of users for high-performance and high-availability infrastructure, the blockchain network has developed into the era of 2.0 architecture based on cloud services. In the 2.0 architecture era, cloud service providers provide users with high-performance, high-availability infrastructure through high-performance servers and cloud computing to con...

Abstract

Disclosed are a replay transaction identification method and device based on a blockchain all-in-one machine. The blockchain all-in-one machine includes a CPU and a smart network card. The smart network card is a network card with a built-in processor or microprocessor, which can perform data calculation and processing. The smart network card can replace the CPU for replay transaction identification.

Description

technical field [0001] The embodiment of this specification relates to the field of information technology, and in particular to a method and device for cross-replay identification based on a blockchain all-in-one machine. Background technique [0002] Blockchain technology (also known as distributed ledger technology) is a decentralized distributed database technology, which has the characteristics of openness, transparency, non-tampering, and trustworthiness, and is suitable for many databases with high requirements for data reliability. in the application scenario. [0003] During the actual operation of the blockchain network, replay attacks may be encountered. The so-called replay attack refers to a node repeatedly submitting a transaction that has already been submitted out of malicious intent or technical failure, causing the blockchain network to execute the same transaction repeatedly, wasting the computing power of the blockchain network , and may cause other los...
