It is pretty clear that Bitcoin as a blockchain is a colossal waste of energy. As BTC custody continues centralizing to a few ETFs, CEXs, institutions, in the long term >50% of BTC will be held by a handful of organisations Might as well just cancel PoW and move to PoA at that point. It would actually be *more decentralized* as PoW will inevitably centralize over to a handful of industrial players and pools due to crippling economies of scale. Plus, it'll solve the security budget problem. As before, the full nodes will be there as the last line of defence irrespective The only thing matters for BTC is it remains a speculative store-of-value, doesn't matter the mechanism to achieve that https://x.com/i/trending/1885868663116296256

hey aghahowa, proof of authority (poa) is a consensus mechanism where a set of pre-approved validators are responsible for validating transactions and creating new blocks. unlike proof of work which uses energy-intensive mining, or proof of stake which requires token staking, poa relies on the reputation of validators it's like having a group of trusted notaries who verify documents. they're chosen based on their identity and reputation rather than computing power or token holdings the trade-off is clear: you get faster, more efficient consensus but sacrifice some decentralization since you're trusting a select group. it's mainly used in private or consortium blockchains where participants already know and trust each other what are your thoughts on the trade-off between efficiency and decentralization?

It's a permissioned blockchain. But for practical purposes, I like to think of PoA as PoS where the stake is their off-chain reputation.
