Yes. That's why I've said that plebs should run a miner as well as a node, even if it's just a mini miner running at a net loss. It seems like a small price to pay for decentralisation.
Plus one can stack a few non-KYC satsin the process.
Organisations like nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze are attempting to mitigate it and others like nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m are looking at decentralising the hardware.
We need hundreds of nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze and nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m to truly achieve this.
Also the increasing trend for Bitcoiners to buy home miners like the Bitaxe: https://bitaxe.org/ and hopefully join smaller pools (solo mining is not going to help), may mitigate the situation over time.
But it is VERY worrying!
Discussion
I’ve been running a nerd miner. Just ordered the S21 chip Bitaxe home miner as my S19 data centre miner got retired in May, a month after the halving.
