| okay, there is a robust repurchase agreement (repo) market on the Ethereum network that allows for anyone to enter the repo market to settle trades of practically unlimited sizes. before last year this was exclusively the domain of investments banks given the privilege of using the Federal Reserve's overnight repo market. Where the Federal Reserve would provide hundreds of billions of liquidity and destroy it at the end of the trade, allowing the banks to use credit to finish deals overnight. in the Ethereum network anyone is allowed to use this, it is called "flash loans" in that market, and as always, writing any transaction on the Ethereum network requires the use of ETH, the native fuel necessary to commit transaction to the state machine and save the state. flash loans = repo market the difference being that on the Ethereum network, people borrow from liquidity pools, instead of newly created dollars like when a central bank is involved. this has much greater accountability and confidence. the transactions are executed in one block, if it is not possible for the operation to return capital to the liquidity pool then the transaction fails and it was never executed, but the person that attempted it still pays the transaction fee in ETH as the nodes still did use compute time. Ether is just necessary to access compute nodes on the Ethereum network - specifically to write, as reading is free - no different than dollars are necessary to access compute nodes on the AWS Lambda network. Its not that complicated. If you don't need to write to compute nodes, and you are also not providing collateral to liquidity pools, then you don't need Ether. |
