Why did the lightning network implement a gossip protocol?

As pointed out by many lightning developers in the past (e.g. Rusty's 1 million channel challenge) the gossip protocol is quite noisy and a part of the BOLTs causing many engineering challenges. Today, I learned that Ethereum's Raiden network does…

Can the lightning network be subject to DoS attacks due to message flooding?

In the current implementations of the Lightning network protocol (c-lightning, eclair and lnd), is there any check that stops spamming/flooding of channel_announcement, mode_announcement or channel_update messages? Assume that these messages are…

In Lightning Network, is the balance publicly announced in real-time? On the one hand, it should be public as it is crucial to the routing mechanism. But, in case that the balance might reveal some private information to the network.. I didn't find…

How to get a full view of the lightning network with c-lightning?

As I understand lightning a node should in principle have a complete view of the lightning network graph (i.e., all nodes and channels). However, I also understand that for practical reasons the view will not actually be fully complete (some update…

Expected propagation delay of channel fee update

If I change the fee in one of my channels, how long does it take for the update to get propagated through the network? Are there any rough estimates on how long until it reaches, say, 90% of the nodes?

Are payment channel attributes in the Lightning Network always directed?

While learning about payment channels, I understood channel attributes like base fees, proportional fees and maximum HTLC size would be directed, i.e., the attributes from A to B would not necessarily be the same as the attributes from B to A.…

Lightning implementations

Why are there two implementations of lightning? Is it because majority agreed on using Go for a reference implementation but a minority dissented that choice and built the alternative C implementation?
