Medina 网络产量详情解释

Medina 网络代币 Pmeer 逻辑上总量为 200287911,实际流通量 200551810.04366634。实际差额 263899.04366634 Pmeer。差额产生的原因来源于两方面的因素:1)qitmeer 早期版本公测奖励;2)由于DAG网络的特殊性,Medina 网络总量控制逻辑无法实现产量的精准控制。

在 Medina 网络正式上线之前,我们邀请了社区用户参与了公开测试,在社区举办了三次挖矿大赛活动,主要涉及版本为 qitmeer-0.8.1、qitmeer-0.8.3 和 qitmeer-0.8.4,在三次公开测试活动中,我们都按照一定的规则给参与的用户承诺了 Pmeer 正式代币奖励,总计发放测试奖励 299650.04366634 Pmeer。这些奖励在 Medina Network 1.0(qitmeer-0.8.5)中通过创世产生,具体奖励细则见 相关说明文档 。

在早期的 Medina 网络中,产量控制规则是把 Pmeer 逻辑总量 200287911 全部视为挖矿产出,而 299650.04366634 Pmeer 的测试奖励并未包含在逻辑总量 200287911 之中,而是当作一种增量的方式进行了处理。因此 Pmeer 理论上的流通产量为:理论挖矿奖励 + 测试奖励。

由于 Qitmeer 网络属于 BlockDAG 数据结构,在所有产出的区块中,会存在蓝色集和红色集两种类型的区块,而只有蓝色集区块才会给与区块奖励,红色集区块则为非法区块,非法区块无法获得区块奖励。在 Medina 网络的产量控制规则中,理论挖矿奖励 = 蓝色区块数 × 区块奖励 = 200287911。由于 Medina 网络的区块奖励为 120 Pmeer,因此产量控制的上限区块设定为 1669066 个蓝色区块。那么,Pmeer 理论上的流通产量为:理论挖矿奖励 + 测试奖励 = 1669066×120 + 299650.04366634 = 200587570.04366634 Pmeer。

由于 Medina 1.0 中已给与奖励的合法区块为 541194 个,因此在 Medina 2.0 中,当蓝色区块数达到 1127872 个时,区块奖励将为 0,标志着 Pmeer 已全部产出。然而在这 1127872 个蓝色区块中,合法蓝色区块只有 1127574 个,因此实际给与奖励为 1127574×120= 135308880 Pmeer。

故,Pmeer 实际流通量为:实际挖矿奖励 + 测试奖励 = 541194×120 + 1127574×120 + 299650.04366634 = 200551810.04366634 Pmeer。

实际流通量与逻辑总量之间的差额为 263899.04366634 Pmeer。为了保证这 263899.04366634 Pmeer 的映射权益,Qitmeer 基金会承诺将按照映射比例换算并购买同等数量的 HLC 将其销毁,放弃映射,以保证这 263899.04366634 Pmeer 的合法映射权益。

根据已确定的映射比例,263899.04366634 Pmeer 可以兑换 27331.06599899 Meer,兑换同等数量的 Meer 需要 1690198.40652541 HLC。因此, Qitmeer 基金会将销毁 1690198.40652541 HLC,放弃映射。


Detailed explanation of Medina Network output

The total number of Medina Network token Pmeer logically is 200287911, the actual circulating volume is 200551810.04366634, actual difference 263899.04366634 Pmeer. The reason for the difference comes from two factors: 1) public test reward in qitmeer early version ; 2) due to the particularity of DAG network, the total amount control logic of Medina Network can not achieve accurate control of production.

Before the Medina network was officially launched, we invited community users to participate in public testing and held three mining contest events in the community, mainly involving versions qitmeer-0.8.1, qitmeer-0.8.3 and qitmeer-0.8.4. In all three public testing events, we gave participating users according to certain rules These rewards are generated in Medina Network 1.0 (qitmeer-0.8.5) via Genesis, as described in the relevant documentation.

Prior to the official launch of the Medina network, we invited community users to participate in public testing and held three mining contest events in the community, mainly involving versions qitmeer-0.8.1, qitmeer-0.8.3 and qitmeer-0.8.4. In all of the three public testing, we promised formal pmeer token to the participating users according to certain rules, for a total of 299650.04366634 pmeer rewards. These rewards are generated in Medina Network 1.0 (qitmeer-0.8.5) via Genesis, as described in the relevant documentation .

In the early Medina network, the production control rule was to treat all of the Pmeer logical total 200287911 as mining output, while the test reward of 299650.04366634 Pmeer was not included in the logical total 200287911, but was treated as an increment. Therefore, the theoretical circulation production of Pmeer is: theoretical mining reward + testing reward.

Since the Qitmeer network is a BlockDAG data structure, there will be two types of blocks among all output blocks, blue set and red set, and only blue set blocks will receive block reward, while red set blocks are invalid blocks, and invalid blocks cannot receive block reward. In the production control rule of Medina Network, the theoretical mining reward = number of blue blocks × block reward = 200287911. Since the block reward of Medina Network is 120 Pmeer, the upper block limit of production control is set to 1669066 blue blocks. The theoretical circulating production of Pmeer is then: theoretical mining reward + testing reward = 1669066 × 120 + 299650.04366634 = 200587570.04366634 Pmeer.

Since the number of valid blocks awarded in Medina 1.0 is 541,194, in Medina 2.0, when the number of blue blocks reaches 1127872, the block award will be 0, signifying that all Pmeer has been produced. However, among these 1127872 blue blocks, there are only 1127574 valid blue blocks, so the actual reward given is 1127574×120 = 135308880 Pmeer.

Therefore, the actual circulation of Pmeer is: actual mining reward + testing reward = 541194×120 + 1127574×120 + 299650.04366634 = 200551810.04366634 Pmeer.

The difference between the actual circulation and the total logical amount is 263899.04366634 Pmeer. In order to guarantee the mapping rights and interests of this 263899.04366634 Pmeer, Qitmeer Foundation promises to convert and buy the same amount of HLC according to the mapping ratio, destroy them and give up the mapping, so as to guarantee the legitimate mapping rights and interests of 263899.04366634 pmeer.

According to the determined mapping ratio, 263899.04366634 Pmeer can be converted to 27331.06599899 Meer, and 1690198.40652541 HLC is required to convert the same amount of Meer. Therefore, Qitmeer Foundation will destroy 1690198.40652541 HLC and give up the mapping.
