What’s MEV?
In the absence of a better explanation, Maximal extractable value (MEV) is a term that refers to various methods used by different market players in order capture more money by exploiting pricing inefficiencies within blockchain transactions.
The naive MEV form is known as “transaction sniping.”
Recent manifestations have started appearing in local Bitcoin memepools, thanks to the advent of ordinary trading. On-chain trading is currently done through pre-signed Bitcoin Transactions (PSBTs), but without going into detail.
Simple: Some users will list photos on a market by creating a deal with details, including the price. This feline grail can be purchased by you, a cat enthusiast, by adding your name, your transaction fee, and signing the transaction. This transaction will be broadcasted and settled by the Bitcoin network.
Easy, right?
It’s not true.
It turns out that cats are very popular these days, and your prize is being eyed by other cat lovers. Due to the openness of these offers, anyone can interfere with your sale. PSBT listings, unlike exclusive sales, are auctions. Each transaction associated with the cat in the mempool is available for bidding. Bitcoin’s block interval of 10 minutes allows cat-opportunists a chance to make money. “snipe” The most valuable items are traded for. The transaction must be included in a block before it can be settled.
This shows that the time it takes for the on-chain to settle is a factor in the vulnerability of on-chain bidding. The problem is especially difficult for those who want to do more than trade cat images.
What is the cause of MEVs?
What’s all the fuss about MEV now? Everyone isn’t up in arms over a few degens bidding against each other on cat photos?
To answer this question, you’ll need to open up a new can of worms. The answer to this question will require you to open up a whole new can of worms.
MEV has become a big deal. MEV-Boost (the software used to coordinate the MEV mining on Ethereum) has been distributed in just under 2 years. 500,000 ETH Rewards. It’s almost 2 billion dollar!
The trading market drives the entire industry. (read: degens)
Automated Market Makers on the blockchain use liquidity pools, a concept that is popular to enable users to trade without depending on order books centralized. The pools are usually composed of two assets like Ethereum and USDC.
Users can interact with liquidity pools when they want to swap one asset for another. Every trade affects their prices by adjusting the ratio between the assets. AMMs, which do not require centralized orderbooks where the buyer and seller are always matched up for every transaction, can instead be used as decentralized contracts on chain.
Upon creation of a pair, users can choose to trade in the pool against it or provide liquidity. To contribute liquidity, you must supply one or both assets into the pool to ensure it keeps the right ratio. Arbitrage is possible when there’s an imbalance. Market makers can buy the asset at the lower price from the pool, and sell it for a higher rate in another venue such as the centralized exchange. These activities and the fees earned by liquidity providers from trades encourage traders to keep markets liquid.
You may have heard of DeFi, but you might not know what they are. Here’s the scoop. The permissionless nature of liquidity pools has led to their popularity. Upon closer inspection, we can observe that these trades are not fundamentally different from the cat market we discussed earlier — they’re just on-chain auctions.
Ethereum’s programmability, and the architecture of its system in general, creates an environment that is ripe for abuse and manipulation.
The most intuitive and popular is probably frontrunning. AMMs do not settle trades instantly. The same as cat snipers are able to monitor Bitcoin’s mempool in search of juicy trades, Ethereum is also staffed with financial mercenaries that diligently watch over each opportunity.
The ETH boys don’t play with it. There’s not Private Ryan there, but SEAL team six. It uses several sophisticated techniques to capitalize on the time difference between when the transaction is announced and confirmed by the blockchain. The frontrunners then place their own trades ahead of original transactions, and can profit from any price shifts caused by their actions. It is common for regular users to get lower prices than they expected. Sandwiching is one of the most common ways to do this. A buy order will be placed before the user trades and then a sale order immediately after. This allows the trader who originally traded the order to capture the difference in price.
Although these dynamics were controversial for their effect on the MEV user experience, the economy of MEVs is much larger than that. While these dynamics have been controversial because of their effect on user experience, they only represent a portion of the MEV economy. biggest source of MEVBy a large margin, the word comes from “Loss-Versus-Rebalancing.” It is a form of pool arbitrage that affects liquidity providers.
Arbitrage traders rebalance a liquidity pool when the asset prices diverge from those at which the assets were initially deposited. This reflects the current global market price. The rebalancing leaves the liquidity providers exposed, since they are unable to adapt to changes in market conditions between blocks. They are easy targets for traders who have access to central order books due to the fact that they’re exposed to old prices. They exploit price discrepancies and leave liquidity providers with an asset mix that is less attractive or a reduced value.
It is an emergency situation. recent research paper On the subject:
In the vast majority of large Uniswap pools, where hundreds of millions US dollars are currently held, we find that fees earned by arbitrageurs is smaller than their losses. It is interesting to note that this result makes us wonder why LPs continue to contribute money into the pools.
The extreme circumstances described may have led to a consolidation of liquidation provisioning by fewer actors.
What is Ethereum and why should we care?
Good question, anon! It’s because I think that a large part of recent discussion around MEV for Bitcoin has completely overlooked the fact these systems do exist within a technological context. Although I can understand that new concepts and unfamiliar terms may cause skepticism, many of the dynamics are now well known. If we only look at this through the technical lens, it does us a great disservice.
We are aware that there have been a number of new ideas floating around for improving Bitcoin’s scripting capability. This could lead to a greater expressivity in the protocol. A combination of these features could allow someone to create the on-chain equivalent of AMM. There’s no doubt that something of the magnitude of Ethereum could have negative effects on Bitcoin’s decentralization. MEV incentivizes high-levels of mining specialization. Matt Corallo from Spiral has created a good guide for those who want to understand the risks. primer Topics to consider
There is no doubt that the key aspect of the subject was largely ignored. The economic incentive is the driving force behind MEVs and all associated systems. Different factors can significantly impact the viability.
The story of the cats shows how the time interval between blocks is crucial to the on-chain game theory. Now, this theory is supported by documented evidence. Researchers generally agree Longer block times can exacerbate MEV issues. Anyone considering AMM systems built on the Bitcoin Blockchain faces a major challenge.
Is Bitcoin in danger?
It’s reasonable to question whether, when comparing Bitcoin with Ethereum and its block interval of 10 minutes to 12 seconds that the Proof of Work-based security is compatible in all of these large on-chain transactions.
Due to the long intervals between Bitcoin blocks, liquidity providers would have to deal with stale Bitcoin prices over extended periods. This makes it difficult, or even impossible, for them to invest substantial capital. The increased latency can increase the risks of MEV abuse and front-running. Arbitrage is a dream come true!
They suggest that Bitcoin on-chain trading may not even be possible. This use case is increasingly optimized for speed and efficiency. Bitcoin has little chance to compete. This architecture is likely to scare away capital investors, while users may prefer platforms more in line with their own interests.
The importance of economics in evaluating technical modifications to the Bitcoin Protocol is highlighted. Do not be misled, economic interests are driving the conversation. They want to duplicate the MEV financial flywheel on Bitcoin. They see this as an opportunity for a billion dollars to reuse proven business models, now that attitudes have changed in regard to the innovation of protocol-level technology.
Bitcoin’s long-term, slow and steady settlement is an effective deterrent for predatory MEV practices. The study is incomplete and more evaluations are needed to determine the MEV risks of layers that have been built on top of the protocol. It’s also a compelling reason for believing that Bitcoin is not as vulnerable to MEV attacks as many people think. Bitcoin’s inherent transaction delay offers a unique protection that makes it less vulnerable to MEV abuse than chains with a faster speed like Ethereum.
