Financial transactions are very prone to manipulation and unethical practices. Front Running is one example. Check out the explanation regarding front running on the blockchain in this article.

Introduction to Front Running

Front running, in the context of financial transactions, refers to the unethical practice of placing transactions in a queue with prior knowledge of future transactions. In blockchain platforms, front running generally occurs when a participant, often a miner or full node operator, exploits their access to information about pending transactions for personal gain.

Front Running pada Platform Blockchain

On blockchain platforms like Ethereum, front running can be done by miners who have insight into pending transactions. By strategically placing their own orders before others, miners aim to capitalize on price movements resulting from those pending transactions. This is often done by offering higher gas prices, speeding up their transaction processing compared to delays.

Full node operators, who are responsible for monitoring network activity, also have the potential to engage in front running. Additionally, centralized exchanges, despite their capabilities, typically have no incentive to defraud their customers.

Front Running Attack Type

1. Generalized Front Running: Taking advantage of potentially profitable contract calls.
2. Displacement Attack: Malicious actors replace the original transaction with their own, disrupting the intended positive effect.
3. Insertion Attack: Inserting the original transaction between two other transactions to gain profit without having to own the asset.
4. Suppression Attack: Slows down the execution of other people's transactions, with the front runner benefiting when the suppression is lifted.

Reduction of Front Running

1. Transaction Ordering: Implementing ordering rules, such as the Canonical Transaction Ordering Rule used by Bitcoin Cash (BCH), helps control transaction ordering.
2. Improving Transaction Confidentiality: Improving confidentiality at various levels of decentralized applications (DApps) helps reduce their vulnerability to front running.
3. Building Anti-Front Running Mechanisms: Develop blockchain protocols and mechanisms that explicitly prevent front running, such as MEV-Boost and Flashbots.

Conclusion

Front running remains a challenging problem in the blockchain space, requiring continued efforts to develop and implement effective preventive measures.

Structuring the order of transactions, increasing confidentiality, and building anti-front running mechanisms play an important role in reducing the risks associated with front running, promoting a more secure and trustworthy blockchain ecosystem.
