Miners should generally choose the fork with the longest length.
This is wrong.
Nodes will follow the chain which has the most accumulated work. This is not necessarily the chain with the longest length.
Usually when we reorganize one or two blocks, then the blocks will obviously have the same difficulty and therefore represent the same amount of work, so the longest chain will be the chain with the most work. However, if a fork lasted long enough to significantly stretch beyond a difficulty retargeting and in to a new difficulty epoch, then blocks on each chain would represent a different amount of work and so the longest chain may not necessarily be the chain with the most work. Nodes will switch to a shorter chain if that chain has more accumulated work.
This is also wrong, let me explain why I was
not wrong.
While a shorter and more difficult fork may offer higher rewards in the short term, it is important for miners to consider the long-term implications. The longer fork represents the consensus of the network, as it has accumulated more computational work and has a greater number of participants supporting it. By choosing the longer fork, miners align themselves with the majority, reducing the risk of their blocks being orphaned or invalidated in the future.
It's worth noting that miners typically rely on consensus rules implemented by the network's protocol and the consensus of the majority of miners and nodes. Following these rules and aligning with the majority helps maintain the integrity and stability of the blockchain.
