They are the infrastructure supplier of this decentralised log book system, to ensure the integrity of the network. Different Blockchain has different characteristic. Log book and wallet function is only a part of it, but due to the nature of "holding value", this wallet function play an important role of a. lock chain existence.

Just like network file sharing system, like torrent file sharing, they're exactly the same thing. Everyone share their resources and we have a torrent network.

If your wife is the audience, show her this photo. Blockchain is the 555 booklet and the bank is the ringgit. She will get the idea. My regards to her and the little one 😜
