# Mining

Stake to earn rewards.
Participants who have staked tokens such as ETH, DAI, USDT and other supported digital tokens in the platform will earn $INSUR token rewards. This process, also known as mining, has been adopted by many other prominent DeFi protocols.$INSUR token mining by capital staked in InsurAce's Cover and Investment Arms is governed by the following equation, with "C" being the constant determined by the token economy adjusted over time:
$Speed(Investment)+Speed(Cover)=C$
This equation ensures that the balance between the Cover and Investment Arm is maintained.
In respect of the capital pools under the Cover Arm, mining speed is determined by the InsurAce protocol's SCR ratio. When the capital pools under the Cover Arm are insufficient to meet the InsurAce protocol's SCR, the SCR mining speed for the Cover Arm increases to attract more capital to them, at the same time helping InsurAce to lower its prices and reduce insolvency risks. Of the capital pools under the Cover Arm, the pool with less capital staked will have its SCR mining speed adjusted to attract more capital. Once there is sufficient capital under the Cover Arm to meet the InsurAce protocol's SCR, the SCR mining speed reverts back to normal, and the Investment Arm's mining speed increases to attract more investment funds.
Given that
$S_i$
is the number of tokens staked in a cover capital pool at time
$t$
, and
$S_\mathrm{max}$
is the number of tokens staked in the largest pool at
$\mathit{t-1}$
whose mining speed is
$\mathit{Speed}_\mathrm{min}$
, the mining speed for pool
$i$
is calculated as follows:
$Speed_i = \begin{cases} Speed_\mathit{min} &\text{if } S_i\ge S\mathit{max} \\ Speed_\mathit{min} \times \lambda(1-S_i/S_\mathit{max}) &\text{if } S_i
where λ is the speed scale, e.g if λ = 2, the maximum mining speed will increase by 200% from the standard speed.
