METHOD AND APPARATUS FOR ESTABLISHING BLOCKCHAIN NODE CONNECTION, AND DEVICE

摘要

Embodiments of this application provide a method and an apparatus for establishing a blockchain node connection, and a device. The method is applied to a blockchain system, and includes: A first node obtains address information of a second node from a first router. The first router and the first node are located in a first autonomous system. The second node is located in a second autonomous system. The first autonomous system and the second autonomous system are neighboring autonomous systems. The first node establishes a connection to the second node based on the address information of the second node. This improves blockchain communication security.
