 Today, I will be presenting about cash flow, which is the way you can pay E to smart contracts without passing E. So, I'm sort of with Surya Khan, I'm the CEO of BackwaterCon, and we are decentralized data autocopers of all, and to get data from our autocopers, you got to pay some E, and that's why we are building cash flow. So, the first question would be how you pay E to smart contracts right now. Pretty simple. You have a payable function, right? The function, this function gets secret data, you just call it, it checks whether you pass enough E, and if you do, it returns you secret data. So, as far as you call smart contracts, that means secret data, you pass some E, and that E is passed along to the contract, it brings some secret data, healthy. But what happens if, you know, calls a contract, and that contract is enough for two contracts, and all those require E. Now, all the contracts needs to accept E, and they speak the E around, right, and also needs to know how much E you need to pay, and that's very messed up. So, it wouldn't be better if Bob just called a contract, and each of the contracts basically takes E from Bob directly, just like the way you call a contract right now, the contract consume gas, and charges the transaction-oriented directly. So, here comes a gas swap. So, you may probably, you can probably guess it. A gas swap is basically a combination of gas token and juice swap, right, it's built in Ethereum, where you can, you know, connect permissionless protocol together to get more use to the things. So, something that may not work in the future, the Ethereum foundation, they're working on the state-run proposal, for example, and that may make gas token not useful in the future, and that also means gas swap will not work too. So, gas token, you can go to the link, gastoken.io, that's the contract address, ESC 20, that you can mint by spending some gas, right, you allocate storage, you get gas token, and when you burn the token, you get some gas refund to save you from some gas cost in the future, and that's essentially gas token, and juice swap, that's the link, you guys probably have a tactical curve that if you send some E to the contract, it returns to ESC 20 token, and if you send ESC 20 token to the curve, it returns to E. So, with gas swap in the case, you have a mint function, basically, takes the log E that you want to have, and it mint to the E, spend some gas, and you burn the function. So, to mint, you just mint gas swap, you sell it to juice swap, and to burn, you just sell the E, and then you get a gas token, and just burn the gas token. So now, instead of wanting to pass out the E, each contract can just call mint function of gas swap, and then there's no E bidding to pass around, nothing needs to be payable, and just pay more gas. Now, it's become simpler to write the app that needs to pay E, right? You don't need to make anything payable, you don't need to help with gas cost stabilization, because now, if you have a deep market of gas token, gas cost should become more stable. The best thing is that it's very efficient. Right now, to mint gas, to mint gas token, you pay also not to get proof as I said earlier. So...
