Blur0's technical review of A7

Blur0's technical review of A7 Let me talk about the record first: Blur tried seven or eight strategies during the operation period from the end of December, and obtained more than 90,000 points in the third stage, distributed in almost 20 addresses. Most of the cost is 0, and there is even a small profit based on the points obtained. I promise the Freeblock group of friends to make a review and summary, hoping to bring some inspiration to everyone who participates in the project in the future. 1. Before being packaged, the ETH transaction will enter the memory pool for miners to choose and package. By monitoring the transactions waiting to be processed in the memory pool, check whether there is an address to be agreed to offer. If there is a transaction that will be deducted , then use a higher Gas to take the money out, because the offer will basically use the low gas recommended by the little fox wallet, so there is no difficulty in this part The only possible loss point is that some transactions are operated through privacy nodes and cannot be monitored without entering the mempool. Also, if the NFT plummets, the preemptive gas is sometimes very outrageous. After this method was discussed by someone in DC, I changed it to avoid slugs like monkey land for bid 2. Bid new collections within 3 hours Because Blur has Opensea mark protection, new Slugs cannot be traded within 3 hours So you can bid without brains. Finally, because of Opensea’s royalty revision, the new collection on Blur has been marked, and you can’t bid. In addition, the competition is fierce. In the middle term, the balance of the bot is basically the competition, so there is no focus on trying this strategy. 3. Start to try some strategies that are not lossless but have an infinitely high profit-loss ratio, and there are also some operations that are actually not smart in the review. Try assuming that the people who use blur are all smart people, and there are very few idiots among the users who gamble on blur, or there are no idiots who lose money to accept Bid when the gas is soaring. Low, the bot gave up after running for a day. 4. Multi-path arbitrage, sequential Bid, from the popular slug on Blur, refer to the highest offer on Opensea and other platforms, if it is profitable, then Bid, and automatically sell after successful purchase. Because it is a passive purchase, it cannot be combined with the contract to make it 100% lossless, and the loss will be rolled back. At the beginning, when the weight is not calculated, some orders are often encountered, and the price is raised to attract the Bot to Bid. This stage has suffered heavy losses (refer to my tweet at the end of December). 5. Sequential bid, this strategy is basically based on quantitative operations, you can see the expiration time of the bid by blur capturing packets, I changed the default permanent to 10-30 minutes to bid, and at the same time retrieve popular slugs in order, this The bot should have earned some ETH while gaining a lot of points, the Liquidity is good, and it should leave enough profit for itself when bidding. Later, I found that the Bid points are related to the proportion of the Topoffer in your Bid collection, so every time you bid, keep your own proportion above 80%. At the end of the day, this strategy is ineffective, because each slug, even if it is not a popular slug, needs an extremely large amount of capital to occupy 80%. In the last stage, we found a strategy that can bypass the blur website, and Bid some collections that cannot be Bid, such as mutant dogs, but this operation is too eye-catching, just a simple attempt. It was fixed when I was wondering whether to open a separate address for the process. insufficient: 1. Part of my account has been banned from the Bid function for a period of time. For the sake of safety, I have done invalid work for a long time to avoid being banned 2. At the beginning, I didn’t optimize a good strategy. Many collection points were scored by my left hand and right hand, but I didn’t measure the number of points in this part, because if there are many points, multiple addresses are definitely appropriate. 3. Blur is updated frequently. As a user, I don’t feel it, but the interface I request blur is often unavailable, and each update cycle is about half a day, wasting too much time. The more frequently blur is updated, the more confident I am in his value, but at the same cost in the later stage, the points obtained are 1/5 of the early stage, or even less. 4. Unexpectedly, the loyalty is an average value. It is useless to cram for the moment. The highest loyalty is 11 points Summary: In this wave, I also helped the friends in the group. A7 is not available, but A6 has some. More people feel that the power of one person is too limited. We should set up a system such as the cloud to go collectively. Come on, such an update cycle, strategies and the like should be better. In addition, there will be a lucky draw for Blur. I wish you all the best!
