Yes, in a sense. The longest blockchain is the "truth." But with independently acting miners and mining pools there isn't a "majority" in the sense of a group of actors bullying the minority. The 51% problem describes this but it probably won't happen. The miners don't want to be a part of a pool that achieves over 50% hashing power because it would undermine bitcoin and sabotage their efforts. Currently the biggest mining pool is either AntPool or F2Pool. They both have about 15% of the total hashing power [1]. - [1] https://blockchain.info/pools https://blockchain.info/pools
