Even still, AIUI the problem with Bitcoin is that a buggy implementation is capable of accidentally hard-forking the blockchain (as demonstrated by <a href="https:&#x2F;&#x2F;bitcoinmagazine.com&#x2F;articles&#x2F;bitcoin-network-shaken-by-blockchain-fork-1363144448" rel="nofollow">https:&#x2F;&#x2F;bitcoinmagazine.com&#x2F;articles&#x2F;bitcoin-network-shaken-...</a> ). The existence of a protocol specification document alone wouldn&#x27;t have prevented that. My question is whether Ethereum actually has some clever mechanism to ameliorate this threat, or whether it&#x27;s just hoping that the existence of multiple implementations means that no one client ever gains more than 50% market share (and hence any hard-fork that results from an incompatible implementation wouldn&#x27;t require a central authority to step in to determine which was the &quot;true&quot; chain).
