The paper "Majority is not Needed: A Counterstrategy to Selfish Mining" explores the issue of selfish mining attacks in the context of Bitcoin. Previous research on this topic assumed that all miners who are not part of a selfish pool will continue to mine honestly, but in reality, this is not always incentivized, especially when other pools employ deviant strategies like selfish mining. The authors investigate a scenario where a large enough pool capitalizes on another selfish pool to gain 100% of the profit and commit double spending attacks. They propose a counterstrategy called "Equal-Forking," which can be used by honest miners to counter any deviant strategy and discourage other pools from implementing such strategies. The paper presents three concrete contributions: first, it introduces a new model for analyzing deviant mining strategies; second, it proposes an effective counterstrategy called "Equal-Forking"; third, it shows that even the possibility of Equal-Forking discourages other pools from implementing deviant strategies. The authors also discuss related work on deviant mining and highlight the limitations of existing solutions. Overall, this paper provides important insights into the problem of selfish mining in Bitcoin and proposes an effective solution that can help maintain the integrity of the blockchain system.

Bitcoin is a type of digital money that people can use to buy things online. Sometimes, people who mine Bitcoin (which means they help keep the system running) might try to cheat and get more money than they should. This is called a selfish mining attack. Some researchers have come up with a plan called "Equal-Forking" to stop this from happening and keep the system fair. They made a new way of looking at these cheating strategies, came up with Equal-Forking as a solution, and showed that it works well. Other people have tried to solve this problem before, but their ideas didn't work very well.
Majority is not Needed: A Counterstrategy to Selfish Mining
In the world of cryptocurrency, Bitcoin has become one of the most popular and widely used digital currencies. However, its decentralized nature makes it vulnerable to malicious attacks such as selfish mining. In this article, we will discuss a research paper titled “Majority is not Needed: A Counterstrategy to Selfish Mining” which explores the issue of selfish mining attacks in the context of Bitcoin and proposes an effective counterstrategy called “Equal-Forking”.
What is Selfish Mining?
Selfish mining is a type of attack that allows miners to gain an unfair advantage over other miners by withholding their mined blocks from being broadcast on the network. This gives them more time to mine additional blocks before anyone else can catch up with them. As a result, they are able to earn more rewards than honest miners who follow protocol and broadcast their mined blocks immediately after finding them.
The Research Paper
The authors of this research paper investigate a scenario where a large enough pool capitalizes on another selfish pool in order to gain 100% of the profit and commit double spending attacks. They propose a counterstrategy called "Equal-Forking," which can be used by honest miners to counter any deviant strategy and discourage other pools from implementing such strategies. The paper presents three concrete contributions: first, it introduces a new model for analyzing deviant mining strategies; second, it proposes an effective counterstrategy called "Equal-Forking"; third, it shows that even the possibility of Equal-Forking discourages other pools from implementing deviant strategies.
How Does Equal-Forking Work?
Equal-forking works by allowing honest miners in smaller pools or individual users who do not have enough hashing power compared with larger pools or attackers (selfish miners) to join forces temporarily when they detect suspicious activity on the blockchain network (such as double spending). By joining forces temporarily through equal forking, these honest miners are able to increase their hashing power so that they can outcompete any attacker attempting double spending or any other malicious activities on the network while still maintaining decentralization within Bitcoin's system architecture.
Limitations
The authors also discuss related work on deviant mining and highlight some limitations associated with existing solutions such as difficulty levels for different types of nodes/miners participating in consensus process or lack thereof incentives for small miner groups/individuals who want participate in consensus process but don't have enough resources/power compared with larger entities like pools or attackers (selfish miners). Despite these limitations, this paper provides important insights into how Equal Forking could help maintain integrity within Bitcoin's system architecture by discouraging malicious actors from taking advantage over others using deviant strategies like selfish mining without sacrificing decentralization within its system architecture at same time .
