Proof-Of-Work Is The Only Viable Form Of Consensus By Pierre Gildenhuys Bitcoin receives a lot of criticism, and much of that criticism focuses on the proof-of-work consensus mechanism that bitcoin utilizes. Proof-of-work, in its under-appreciated existence, quietly secures the network, makes the distributed ledger of Bitcoin immutable, and creates a free and open market for wasted and excess energy. Essentially, the consensus mechanism of bitcoin is what makes it enables its other unique properties to continue their existence, and therefore, is the only viable form of consensus for the network. Opponents of Bitcoin often point to proof-of-stake protocols as alternatives, but they would immediately dissolve the pristine level of protection the Bitcoin network exhibits. |
