Search for &quot;on stake and consensus&quot; I&#x27;d link to it, but I&#x27;m on mobile right now. Btw- I know you&#x27;re new to blockchains because poelstra has been writing seminalpapers for years and you haven&#x27;t even heard of him.<p>We know things are true in a blockchain because energy went into it. If only a single Bitcoin node were alive, and 99% of the network disagree with him - the energy would point to the truth. This is what makes it objective. With subjective chains there are a huge suite of problems in the form of stake grinding and long&#x2F;short range attacks. Why does this matter? Non-objective quorum based sysetms have been around for decades. They&#x27;re not more efficient than centralized systems for many economic reasons, some of which were really well laid out in a Isabella kaminska paper on the subject (let me know if you need a link)<p>Tldr: blockchains aren&#x27;t paxos or raft. Blockchains mostly suck, but do one thing well: resist censorship
