Abstract

Abstract:

As a blockchain 3.0 technology for the Internet of Things, IOTA has many advantages such as no transaction fee, high throughput, support for offline consensus of transactions, and strong privacy. However, the Internet of Things in the multi-domain scenario may cause network resources to be isolated when multiple heterogeneous sub-nets cannot connect with each other in a certain period of time. In order to solve the problems of the scalability and storage consumption of IOTA network in the multi-domain scenario, taking the IOTA network using DAG structure as the research object, this article proposes an optimizing scheme on multi-domain collaborative IOTA blockchain technology for the Internet of Things. In the multi-domain scenario, multiple regional networks are divided in the unified IOTA network environment. This scheme uses special nodes which have sub-net division views of the whole IOTA network to communication among sub-nets. The experimental results show that the scheme can improve the scalability of the IOTA network, save storage consumption and be of great significance for the IOTA network to adapt the multi-domain scenario of the Internet of Things.

Key words: blockchain 3.0, IOTA, regional shard
