BIS Issues Warning Regarding Front-Running Threats In Cryptocurrency Mining

For a couple of years, miners operating on the blockchain of Ethereum have extracted more than $600M from the rest of the investors, as per an exclusive report issued on the behalf of the Bank of International Settlements (BIS) aiming at common misconduct within the industry of crypto mining.

The bulletin of 16th June proposes 3 main takeaways from the research of the BIS on the Ethereum protocol’s operations. The initial is not unexpected, which witnessed that Ether (ETH), as well as the decentralized finance (DeFi) protocols constructed on it, depend on miners or validators as mediators to certify the transfers as well as for the ledger’s update. The report’s main stance is centered around the exploitations these mediators can do with miner extractable value (MEV).

As noted in the report, since these mediators can select for which transfers they incorporate into the ledger as well as in which manner, they can also get involved with the operations that would be unlawful in conventional markets like sandwich and front-running trades. A more specific description in the report denotes MEV to be the profit that can be gained by the miners by exploiting the sequencing as well as the choice of transfers incorporated into the blockchain.

The authors anticipate that 1 of thirty transfers in the blockchain of Ethereum is incorporated on the behalf of the miners for false profiteering. As the report puts it, MEV looks like front-running done by brokers operating in conventional markets however, contrary to that exercise, is not unlawful itself.

The report mentions that if a miner witnesses a huge incomplete transfer within the mempool due to which a great change can be incorporated in market prices, a corresponding sell or purchase transfer can be added by it just in advance of this huge transfer, thus gaining profit from the price alteration. The 3rd point discloses that MEV counts to be a fundamental vulnerability of the blockchains that are pseudo-anonymous, and hence no convenient method is there to escape it.

As specified by the BIS, it presents a hazard to a series of unique DeFi-based apps and could enhance in the coming time, making it necessary. Nonetheless, no approach has been suggested by the report to deal with the MEV in legitimate distributed ledger technology depending on a trusted mediators’ network with open identities. This is so to give up blockchain’s fundamental worth of anonymity.
