Earlier this year I posted an advisory on a possible attack on certain cross-cryptocurrency atomic swap contracts.

Network views tend to be the view of the network from a single node, or small selection of nodes. They are not complete views of the network. This is impossible to achieve. Even if many node views were combined, it would still be incomplete.
These network views, or network maps, have been termed 'visualisers' by the LN community.
Screenshots may reflect older visual styles, and are dated accordingly.
Half-baked thoughts exploring a different way of implementing a fully-validating BCH node.
The idea is to shift the storage of full transaction data to wallets, and explore how little data a fully validating node could store. This isn't a problem today (the UTXO set easily fits in the RAM of an inexpensive server-class machine), but might eventually be at very large transaction volumes.
Initial block download is a problem today (it is annoying to have to wait several hours or days to sync up a new node), and this scheme could make it orders of magnitude faster by shifting the time when full transaction data is broadcast from initial block download to new transaction announcement.
