Assume that reward policy of Ethereum is changed from 3eth to 1eth.
Hard fork is ongoing but, there are miners who don't consider updating their software.
what happens?
The miner who did update will record reward of coinbase transaction as 1eth, but the miner who didn't update will record reward of coinbase transaction as 3eth.
Assume that number of miners is 10 in the world. three people did update and others didn't. three people know the reward is 3eth but seven people know the reward is 7eth. it result in remains inconsistent between two groups.
My questions :
- The senario explained above cannot do hard fork. blockchain will be got screwed if the blockchain initiate hard fork. so how to successfully achieve chain consistency?
Sorry for my English.
