An explanation for the comunity of this table, please ? https://jcash.network/proof-of-solvency

What is exactly in that context : "Solvency Requirement"? Liquidity ? Circulating ? JNT requirement ? Is possible some practical exemple ? Thanks

In order to be able to give examples, I made a screenshot of the Proof Of Solvency page, since the values can vary over time. My examples all refer to the screenshot which you can find here: https://i.imgur.com/4BDtwA2.jpg

Currently, 186.43 jEUR, 84.09 jGBP and 480.04 jUSD are circulating. Basically, this means that someone has sent ETH to Jibrel and received jCurrency tokens in return, so that they are now in use.

Whenever a jCurrency token is in circulation, it has to be backed by JNT. This can be explained best using jUSD as an example. At a current price of $0.10 per JNT, 4,800.40 JNT would be required to cover all 480.04 jUSD in circulation (JNT requirement = Circulating amount of jUSD / JNT price). For currencies other than jUSD, these must first be converted into the theoretical value of USD at the current exchange rate, because the price of JNT is also in USD and only then the JNT requirement can be determined. Another example: 186.43 jEUR is currently in circulation. However, you cannot divide this amount by the JNT price, since it is given in USD, so that the theoretical value of jEUR in jUSD must be calculated first. At the time of writing, the conversion rate from EUR to USD is 1,1635. If you now multiply the amount of 186.43 jEUR by 1.1635, you get the theoretical value of 217.91 jUSD, which you can divide by the JNT price of $0.10. As a result, the JNT requirement for 186.43 jEUR would be 2,169.10 JNT what is almost identical to the 2,168.80 JNT shown in the screenshot.

Solvency required is the sum of all JNT requirements (2,168.80 for jEUR + 1,098.64 for jGBP + 4,800.40 for jUSD = 8,068).

In terms of liquidity, any value greater than 100% means that more than enough JNT are available to fulfil the solvency requirement. A large value indicates that more JNT have been pledged than would actually be needed. It can be calculated as follows: JNT Pledged * 100 / Solvency Requirement.
