Anchor is a defi service that users can use their assets as collateral for borrowing, which means if you have some LUNA in your wallet and you need some money and in the same time you don’t want to sell your LUNAs, you can use them as collateral and deposit it in the Anchor protocol and borrow some UST instead. Anchor accepts LUNA and ETH as collateral. Tokens which are deposited in Anchor will be bounded and will be shown as b+token name: bLUNA, bETH, … The bounty asks that: how much of the collateral provided on anchor is bLUNA vs. bETH? And as I did some selects on anchor. Collateral table I realized that there is a contract_label for each asset and there is a event_type that shows what act user did and here I filtered my result for event_type='provide' .

And here is the total result for bLUNA vs. bETH collateral:

for part two which is: how has this changed over the past 90 days? I did a query and made a chart with it to show the changes over past 90 days. a chart is more understandable than numbers :)
