They ' re just kids who use ideas and words to suit themselves . Take Mark Friedenbach . This is one of the guys like Greg etc that ' s always making the argument that only the heaviest valid chain is authoritative , with lots of emphasis on valid . They promote this argument in order to defend the block size limit . See , only by running a full node can one ensure that the heaviest chain is valid . So that means that we need to make sure that everyone can run a full node , else we won ' t be able to ensure the chain is valid against malicious miners . Sounds great right ? Then they say , here ' s a great idea it ' s called a soft fork ! It allows miners to change the protocol without your realizing it changed ! . In other words , soft forks shit all over your ability to validate . facepalmThose guys are either good saboteurs or just plain idiots . I used to think they were idiots . But really , nobody ' s that dumb .
