Lightning Network co-founder and MIT software engineer Tadge Dryja said on the podcast that the lightning network is the real main network, but its function and operation are still very much like the test network. He stressed that people did not use the lightning network for real transactions, and the lightning network almost did not involve people buying goods through this medium. Tadge Dryja believes that lightning network will be important if adopted between exchanges. For example, an exchange allows users to deposit and withdraw money through a created channel, and when the transaction is completed, they can directly transfer funds back to their channel. The use of lightning networks will be even more important in the cryptocurrency industry, he added.
