the linked "chinese guy" is not inventing anything. but instead highlighting consensus.
which is something we all should be thinking about and utilizing. and should always do
I have been following the discussions on chinese forums during this year and I can confirm the idea is new
The first proposal was to setting up an mining pool and attack/destroy the minority chain after a hard fork. That was at the end of June, so called "the terminator plan"
http://8btc.com/thread-35645-1-1.htmlThe second proposal was on 10th Oct, the author was inspirated from Ethereums "hash rate bomb", suggest to raise the difficulty dramatically if the chain has largely reduced hash power, but I don't know how that can be implemented for non-upgraded nodes
http://8btc.com/thread-40576-1-1.htmlThen 5 days later, the latest "Terminate the hard/soft fork debate: Safe hard fork is soft fork" proposal by Jiang ZhuoEr
http://8btc.com/thread-40796-1-1.htmlThis last piece of article fully analyzed the different means to kill the minority chain, he suggested two approach for upgraded majority miners: Merged mine and mine empty blocks for the old chain forever to disable it forever, or mimic segwit, move all the transactions to extended block to disable the original chain's ability to do any transaction
The breakthrough is that this approach changed from social attack to code attack, e.g. attacking the minority chain by codes, not mining pools, so that every upgraded miner will participate in the attack automatically
Then naturally following his thoughts, the most simple real world example of using code to attack minority miners is a soft fork, almost everyone knows. So I suggested to simply use soft fork to attack, instead of other complicated mechanism, it achieves the same result but much easier to implement
