Bitcoin, the pioneer of blockchain technology, showcases a strong foundation in certain aspects of decentralization:
Validator Count: It has the second-highest validator count, earning an 8/10.
If he refer to total Bitcoin nodes,
Client Ecosystem: Dominated by Bitcoin Core, leading to a 1/10 score.
It's true most nodes use Bitcoin Core. But it totally ignore existence of other Bitcoin full node software.
Permissionless Nature: Scores a perfect 10/10, with no permissioned elements.
It's not perfect when miner have full right to decide which transaction to be included on their mined block.
Governance: Lacks on-chain governance, resulting in a 0/10.
Giving 0/10 is ridiculous, on-chain government doesn't always offer better decentralization mainly due to who can vote and weight of their vote.
Consensus Mechanism: Proof of Work (PoW) without native delegation, scoring 5/10.
Without detailed reasoning, i feel 5/10 is rather low score.
Community Diversity: A growing “wizard faction” contributes to a 5/10 score.
I don't know what he mean by "wizard faction". But i agree Bitcoin community could be more diverse.
I've always suspected that big players like Bitmain could build a lot of hashrate to increasingly centralize Bitcoin. For the experts in the house, how true is it that Ethereum is more decentralized than Bitcoin?
I'm not expert, but personally i say not true when the measurement has some flaws and lack of explanation.
