Random idea. Would it be faster than the current, built in, method?
One of the bottlenecks about blockchain stuff in general is the time it takes for new blocks to spread through the network. Due to the probabilistic nature of mining, sometimes multiple miners find a good hash for the same height within a short amount of time. The faster the network learns about a new block, the less time there is for disagreements (forks, we call them) about whose block is the winner.
There are mechanisms in the Bitcoin protocol to cut down on the amount of information that needs to be transmitted about new blocks. One, for example, is to only transmit transactions that the other node doesn’t know about yet. This seems to me something that can be done efficiently with the SAFE network.
Related, but not identical: SAFE will be a good distributed store for that bloated excuse for a data structure (i.e. the blockchain.) It won’t make Bitcoin scale all that better, but maybe a little.
