Such switch happened once.
It was found, that due to overflow, someone issued a lot of bitcoins to themselves in the block. During several hours was released a new client, which ignored flawed blockchain. When most people moved to a new client, the new blockchain overcame the exploited one.
Though it was when bitcoin wasn't popular.
- vessenes 15y agoI was (and still am) a bitcoin user during this period, it was managed relatively easily and quickly; major miners updated their clients and within a few hours, the competing blockchain had died off. This would likely be even easier to accomplish today; as things currently stand, all mining pools and groups have a vested interest in maintaining the integrity of the blockchain.
