Binance #Launchpad continues to mine this issue $PORTAL . There are many price prediction articles, which are basically calculated based on Launchpad’s historical earnings. The price is between 1-3U, the off-site price is also 2+, and Aevo is also around 2.6 , relatively transparent. After reading the Portal official website documentation, the token burning mechanism is a bit interesting. It is easier to understand by directly drawing a picture: First of all, #Portal is a Web3 cross-chain game platform. Currently, more than 200 games have been added to the Portal platform. The cross-chain technology relies on LayerZero, but it is worth mentioning that Portal has built its own synchronization layer (synchronization layer) in addition to LayerZero. The synchronization layer can provide a second layer of verification for cross-chains and increase security. Roles in Portal: In addition to the two main roles of players and game projects, because of the synchronization layer network, there is another role - node; in addition, it is worth mentioning that there is also a role in Portal called Spectators (or Spectators). The role of data sampler) is mainly because when the platform reaches a certain scale, player data itself is also very valuable, and observers are those who hope to access player data, and they pledge to game players in exchange for it. Permission to sample personal data. Therefore, in the Portal ecosystem, players pay game fees, which go into the treasury; game developers can obtain income from the treasury; in addition, the funds in the treasury will also be used for node rewards and player rewards. Staking $PORTAL : Players can pledge $PORTAL to vote for the game. Game developers can also pledge $PORTAL to vote for themselves. The number of votes determines the exposure of the game. Players who participate in voting can get the baseline minimum reward of the platform; the game is based on the votes it receives. You can also get platform native rewards. The baseline minimum reward is the reward issued from the treasury to the pledgers who participate in voting or effective platform governance. The specific reward amount is related to the pledge amount and the pledger's contribution to the platform. In addition to staking to vote, observers can stake gamers to gain access to players’ personal data. $PORTAL #代币经济模型 : The most important part of the economic model, the single-token model, is mainly to balance the inflation of the token.In the platform ecology, the release channel of $PORTAL is mainly the rewards for participants; and the most important channel for token recovery is staking, so it is enough to balance the relationship between rewards and staking. Calculation of reward emission: Portal uses the calibrated Sigmoid function to calculate the emission rate of reward tokens in each cycle. The Sigmoid curve is an S-shaped curve like the one below. It can be seen that in the early stages of the project, the supply growth rate is small. Entering the mid-term development stage, supply increased significantly, and the growth rate slowed down further in the later stage. The parameter k is adjusted according to the initial supply, and the parameter c can be adjusted according to the time when the project development enters the middle stage. The reward share G issued to the game is calculated based on the pledge rate S: G = √S, because the pledge rate represents the player’s participation; the reward share issued to the node N =0.20 · G. Finally, back to the token #燃烧机制 , when $PORTAL is used for network transactions, a part of $PORTAL will be burned and destroyed. The burning rate B is related to the pledge rate at that time: B = 1 − S, and the remaining part is used as a platform reward. You can look back at the first picture. If calculated based on the price of 2.5U, the return rate of FDUSD in Launchpad is about 1%. If you don’t want to bet on the continuation of Launchpad in the next issue, you can redeem and sell it in advance.
