🤓 Game Theory in Cryptocurrencies: How Mathematics Ensures Blockchain Security
Game theory in cryptocurrencies is the foundation, but it’s still interesting to recall what the blockchain is built upon 😁
Let’s break down how this concept shapes security and economics within the system.
✍️ What is Game Theory?
It’s a branch of mathematics that studies the behavior of players in systems where their decisions influence one another.
🖥 How Does Game Theory Work in Blockchains?
In Bitcoin, it helps motivate miners to act honestly.
Economic incentives and the Proof of Work algorithm create an environment where it’s simply unprofitable for attackers to harm the network.
As a result, the rational choice is to act honestly and earn rewards.
🤖 Optimistic Rollups and Validator Games
In Layer 2 systems, such as optimistic rollups, validators assume each other’s honesty.
If someone tries to cheat, others will challenge it 😮
Scenario examples:
1️⃣ Both validators are honest — the network is stable, everyone gets rewarded
2️⃣ One is dishonest — the network slows down, the dishonest one loses their reward
3️⃣ Both are dishonest — the network functions, but users suffer
It’s somewhat reminiscent of the “Mafia” game, where you need to identify who’s playing unfairly 😈
➡️ Why Is Game Theory Important?
It makes blockchains resilient and predictable.
Thanks to these principles, Bitcoin remains one of the most secure networks.

✍️ What is Game Theory?
It’s a branch of mathematics that studies the behavior of players in systems where their decisions influence one another.
The task is to predict the rational behavior of participants.
🖥 How Does Game Theory Work in Blockchains?
In Bitcoin, it helps motivate miners to act honestly.
Economic incentives and the Proof of Work algorithm create an environment where it’s simply unprofitable for attackers to harm the network.
Example: If miners invest in equipment and then behave dishonestly, they risk losing all their invested funds.
As a result, the rational choice is to act honestly and earn rewards.

In general, game theory is the backbone of crypto-economics, applied not only in PoW but also in PoS blockchains, guiding the actions of validators.
