in Bitcoin, the block chain consensus mechanism uses the longest chain selection confirmation process that POW, requires six blocks.
suppose that the number of all nodes that can be detected is 10000. If someone maliciously accesses 20000 full nodes and does not follow the longest chain selection specification of six blocks, will this have any impact on this chain?
after the analysis of the boss
my idea is equivalent to a set of consensus mechanism different from the original chain, and is not compatible with the original chain
in fact, this is the so-called hard bifurcation, counterfeit currency
even if you have more nodes than regular nodes, but you will not be recognized by people who also follow the official consensus mechanism, branches that are not recognized, no matter how many you are, there is no meaning to exist
preferred, the concept of six blocks in the longest chain mechanism is relatively secure, and it is not the longest chain mechanism, so six blocks are required, which is a relatively secure concept. In it, if there are 10000 nodes, plus 20000 nodes, then there are a total of 30000 nodes, and 20000 nodes have exceeded 51% computing power, so the record can be tampered with.
secondly, add that the chain is no longer bifurcated all the time, and following the longest chain mechanism is the correct block that has been identified (the block under the node consensus).
from the second floor, the concept of hard bifurcations and counterfeit coins may have understood what the landlord said: "do not follow the longest chain selection criteria for six blocks." your sentence is a little ambiguous.
