There doesn't seem to be anything in the original email that's specific to BIP 157. It's a restatement of the arguments against light clients: - light clients are a burden on the full nodes that serve them - if light clients become more popular, there won't be enough full nodes to serve them -

Hi Chris, While approaching this question, I think you should consider economic weight of nodes in evaluating miner consensus-hijack success. Even if you expect a disproportionate ratio of full-nodes-vs-SPV, they may not have the same economic weight at all, therefore even if miners are able to

I think that one of the solutions here is to have light clients choose their full node tethers explicitly. Even if you think it is unrealistic to have everyone run their own node (fwiw, I don’t), there is still a trust model where you can pick your trusted source. This way you could have many

2020-05-06 Thread Antoine Riard
What I'm thinking more is if the costs of security are being too much externalized from the light clients onto full nodes, nodes operators are just going to stop servicing light clients `peercfilters=false`. The backbone p2p network is going to be fine. But the massive LN light clients network

Hi Antoine, Consensus capture by miners isn't the only concern here. Consensus capture by any subset of users whose interests diverge from the overall consensus is equally damaging. The scenario I can imagine here is that the more light clients outpace full nodes, the more the costs of security

I do see the consensus capture argument by miners but in reality isn't this attack scenario have a lot of assumptions on topology an deployment ? For such attack to succeed you need miners nodes to be connected to clients to feed directly the invalid headers and if these ones are connected to
