according toaccording toOKEx Official Announcement

, OK Jumpstart will conduct an appointment-winning sale of En-Tan-Mo (ETM) on June 10, Hong Kong time. The first round of sales will be at 12:00 on June 10 (HKT), and the second round of sales will be at 6 At 13:00 on June 10 (HKT), 12.5 million ETM will be sold in each round, and ETM/USDT and ETM/USDK transactions will be launched at 15:00 on June 10.

According to the announcement, the sale price is 1 ETM=$0.1, and the conversion ratio is determined by the market price of OKB on the day of sale. The minimum number of individual reservations is 5,000 ETM, and the maximum number of reservations is 40,000 ETM.En-Tan-MoAccording to the official introduction, En-Tan-Mo (ETM for short) is based on Nash equilibrium and value transfer theory, the first new generation blockchain project to achieve SHD completeness.

In January this year, it announced the completion of the 20 million yuan (RMB) B round of financing, and the capital was Wuhan Siwei Mofang Technology Investment Co., Ltd. The project has received 50 million yuan of A-round financing at the beginning of last year.One of the highlights of En-Tan-Mo isTwo Nobel Laureates (Professor Sargent, winner of the 2011 Nobel Prize in Economics, and Professor Glashaw, winner of the 1979 Nobel Prize in Physics) as advisors

, to provide academic support for the design of its incentive mechanism. In terms of product design, the biggest feature is its consensus mechanism UPOS, which advocates fairness and direct participation in mining.Odaily has been in ""Introduced this mechanism and the similarities and differences of other consensus mechanisms. The relevant UPOS block production process in this article is as follows:

1. Convert the stakes of all voters into corresponding votes through convex function mapping: the principle here is to suppress the stakes of large investors and encourage retail investors.

3. The selected miners participate in the random lottery together (combined with chaotic sorting and improved PoW), the winning node has 3 seconds to produce a block, and if the block is not successful within 3 seconds, it will be skipped.

2. Combining with factors such as time and past performance of nodes, the probability of being elected for each node is calculated, and 101 nodes are selected in each block generation cycle to participate in this round of competition for block generation.

Time is the length of holding currency. A retail investor who holds currency for 2 months may bring more probability of being elected to the node than a large investor who holds currency for 1 day.

3. The selected miners participate in the random lottery together (combined with chaotic sorting and improved PoW), the winning node has 3 seconds to produce a block, and if the block is not successful within 3 seconds, it will be skipped.

4. Start the next lottery. The result of the lottery is determined by the hash value of the previous block, which is difficult to predict. Enter the next cycle after completing 101 blocks.

4. Start the next lottery. The result of the lottery is determined by the hash value of the previous block, which is difficult to predict. Enter the next cycle after completing 101 blocks.

"The bottom 80% of the books can also account for 50% of the traffic." Just as the Amazon online bookstore has subverted the sales ratio of the 28th law, ETM hopes that the nodes in the long tail of the ranking can also be selected. Founder Aaron Yuan said that the UPoS consensus mechanism does not want the node with the most votes to be the block producer for a long time.

Odaily is curious, won’t the practice of suppressing large investors directly disperse coins, operate multiple nodes, and put them in multiple wallets?

"It may be dispersed, and no economic system can completely suppress the existence of capital." ETM hopes to reduce the monopoly of capital to the greatest extent through mechanism design. Aaron explained that first of all, the number of votes can only affect the probability of being elected. A large household may not be elected if all the rights and interests are invested in itself. It is better to put eggs in multiple baskets to increase the probability of winning.

"Linear revenue is acceptable, but ASIC mining machines generate exponential revenue. Mining machines that are several times more expensive than laptops have hundreds of times higher revenue. What we want to suppress is this monopolistic revenue." he added.

Summarize the characteristics of the ETM consensus mechanism:

First of all, it is a probabilistic event for UPoS nodes to participate in the competition, and it is possible to be elected regardless of the number of votes. From the perspective of the number of nodes, the number of nodes in Cosmos is at most 100, and the number of votes is too high to have no chance to produce blocks; the number of votes of UPoS nodes only determines the probability of participating in the "competition to produce blocks", which prevents large households from continuing to monopolize the right to produce blocks.

Second, UPoS has a very low threshold for nodes. Tezos has a high threshold for holding tokens for nodes, 10,000 XTZ reaches RMB 10 according to the market price, but there is no requirement for the number of nodes.

Third, the idea embodied by UPoS is more "socialist" or "equality of results" - the more votes a large household has, the more likely it will be to support the election, but the rate of increase will be smaller than that of retail investors. ETMs are called convex functional relationships.

Finally, UPoS encourages direct participation, not representation.

ETM block rewards are 6-2 ETM, decreasing year by year. 48% of the total amount will be distributed to miners; 5% will be distributed to voters, of which 2.5% will be distributed in the form of fixed income (you can get it when the voted node enters 101), and the rest will be distributed in the form of a lottery, which will be drawn every 5 minutes. to one person. This is different from other PoS public chains, which seem to reward miners more than voters.

In this regard, Aaron’s response is to encourage every user to be a miner and directly participate in block generation without the need for an intermediary. ETM has developed a one-click mining software for this purpose. Users only need to install it on their computers to become miners. Ordinary laptops equipped with independent display and i5 dual-core CPU can be installed.

This software also has a dual-mining design: since the UPoS PoW algorithm is compatible with ETH, if the node is not selected into 101, it can also use idle computing power to mine ETH.
