I like simple diagrams to think with. This is my latest, below, showing what today's 'decentralized architectures' look like, and what a 'real' decentralized architecture should look like.

My point is don't call something 'decentralized' just because you push some cool functionality to the edge. If you still have trusted entities in the middle (gatekeepers), invisible and subtle though they might be, it's still centralized.

On the other hand, a 'real' decentralized architecture pushes these trusted entities into being 'anchors', not gatekeepers.
