This is called a Sybil attack and there are various defenses against them. For PoW systems, anyone who mined blocks in the longest chain wants to get them to as many people as possible to ensure they stay in the longest chain so they get to keep their reward. It's very hard for a third party to stop two people who want to exchange information from doing so. | |
