yes, of course it is. we have a strict decentralization verification process.
we guarantee decentralization by having every LN transaction’s route be chosen by a single server, kept in a closet at your mom’s house o.O
A paper from 2020 co-authored by Christian Decker shared that 10% nodes hold 80% liquidity:
LN: A second path towards centralization of the bitcoin economy - https://arxiv.org/pdf/2002.02819.pdf
Liquidity in 2024: https://mempool.space/lightning/nodes/rankings/liquidity
Maybe someone could write another paper with present stats including use of custodial wallets
the beauty of the LN protocol is that you actually can be the decentralization you want to see in the world, by running your own node
