Ok I see. In practice this reminds me of the issue of downloading the client and of seed peers that every cryptocurrency has: - everyone downloads the client/code of a cryptocurrency from the same place - that client also hardcodes a list of peers that you first connect to in order to discover more peers The first issue is more problematic, and the second issue usually matters less. My guess is that algorand rely on relay nodes because they are targeting a high throughput, and thus need quick communication between nodes.
