What Is Selfish Mining?
Selfish mining is a type of attack that can be used by miners in the Bitcoin network to increase their own profits. It works by allowing miners to mine blocks without broadcasting them to the rest of the network, thus giving themselves an advantage over other miners who are not aware of these blocks. This allows selfish miners to gain more rewards than they would otherwise receive if all miners were playing fairly and honestly.
The main problem with selfish mining is that it undermines trust in the Bitcoin system as a whole, since it gives some users an unfair advantage over others. Additionally, this type of attack could lead to centralization within the Bitcoin network, which goes against its decentralized nature. As such, many people have argued for measures that would prevent or discourage selfish mining from taking place on the Bitcoin blockchain.
