I would like to know what the researchers think of the consolidation of miners within Bitcoin.<p>From the whitepaper &quot;Miners with capacity smaller than 1&#x2F;4 of the total network are incentivized to follow the protocol.&quot;<p>Yet, if any two of the five biggest mining pools collude, <a href="https:&#x2F;&#x2F;blockchain.info&#x2F;pools?timespan=24hrs" rel="nofollow">https:&#x2F;&#x2F;blockchain.info&#x2F;pools?timespan=24hrs</a> they&#x27;d already be over 1&#x2F;4th of the network. And if three or more collude, they could take over the entire thing.
