# Security ### What are the guarantees that the equipment will not be disconnected from the network? We use industrial power grids, as well as our own substations with a backup connection. This guarantees the uninterrupted operation of our equipment. *** ### How can I verify the authenticity of the digital miner? To be sure that you buy authentic digital miners, we recommend that you purchase them in your GoMining personal account. However, if you choose to buy our digital miners on other marketplaces, be sure to pay attention to the network and smart contract address. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
