Dandelion

• Focuses on obscuring network traffic activity by randomizing the pathways through which transactions get dispersed on a decentralized network.
• Being used in Beam
• From a paper (Summer 2019) by Andrew Poelstra (Blockstream) and David Vorick (Sia):

"..a transaction propagation scheme. The way this works is that you send a transaction along some one-dimensional path of peers during a stem phase. Rather than flooding the transaction to the network, which means the origin node can be determined by spy nodes on the network, you do the stem phase and then a fluff phase which makes it much more difficult to do that kind of spying analysis."

• DigiByte has activated Dandelion++ in 5-2019, but it is not clear how the two are related.
