         | It is my understanding that there was never a run on a solvent

         | causes of them. It should also be pointed out that most bank
         | failures were clearly caused by so-called 'unit banking', where
         | the government prohibited banks from having multiple branches
         | in diverse areas. Less-regulated banks (such as those in Canada
         | and Scotland) suffered fewer failures, and had no issues with
         | runs.

               | Some coins (PoS specifically) allow staking, which allows
               | you to set it aside a certain amount, which is then used
               | to validate other transactions, and you earn rewards. In
               | traditional banking, this is kind of like a CD, and your
               | money is used to help the bank out and it pays you
               | interest on that.
               | 
               | The Ethernet (and a few other coins Solana comes to mind)
               | ledger allow for the creation of smart contracts
               | (applications that run on the blockchain) that could
               | (probably some already exist) allow you to automate the
               | creation loans on the ledger, witnessed by the world,
               | that automatically pay you back. You can probably use the
               | smart contract to do a modicum of due diligence on the
               | borrower. But instead of paying SynapseFi (or other but
               | first name that came to mine) thousands a month to allow
               | you to build out loans, its all there for you on the
               | block chain. This probably IS the future of peer2peer
               | lending, as it is already a HUGE industry, and this would
               | kind of get rid of the middle man.
               | 
               | One aspect of banking that is not really needed anymore
               | would be the storage of assets. That is a built in part
               | of cryptocurrency.
               | 
               | There is still the question of how do you get crypto, and
               | for now, and until more people use it for everyday
               | actives, that requires exchanges. And Exchanges could be
               | seen as a centralization of sorts, but even they are a
               | dime a dozen so they are effectively decentralized. And
               | most support transferring to a wallet. So... kinda

           | Let's review the 2008 financial crisis.
           | 
           | The was a thing called a credit default swap. It's a type of
           | insurance. If you make a loan, and the borrower fails to pay
           | you back, the insurance pays you instead.
           | 
           | The insurance actuaries did the math on how much these should
           | cost based on the historical rate at which homeowners paid
           | back their loans. They also calculated that most of the
           | claims would be offset by the ability to foreclose on the
           | house, so they'd only have to pay to the extent that the
           | homeowner owed more on the mortgage than the house was worth.
           | That seemed pretty unlikely, right?
           | 
           | Enter moral hazard. If you're a bank buying credit default
           | swaps, you don't care one bit whether the borrower can pay
           | back the loan, so you issue loans to everybody. Banks issuing
           | loans to people who can't afford them inflates a housing
           | bubble.
           | 
           | The regulators who should have seen this and said "hey wait a
           | minute" instead said "neat, they're promoting home ownership"
           | and just let it happen.
           | 
           | Then when those borrowers, in fact, can't afford the loan
           | payments, they default.
           | 
           | Around the same time, the insurance companies figure out that
           | they fucked up real bad, so the price of credit default swaps
           | goes way up and banks stop buying more of them. Which means
           | they stop wanting to loan money to people who can't afford to
           | pay back the loans, and the housing bubble pops. That puts
           | the existing loans underwater, which would bankrupt the
           | insurance companies, which would in turn bankrupt the banks.
           | 
           | Then the "solution" became to set interest rates to zero to
           | reinflate the housing bubble, where they've been ever since,
           | and we now have an even bigger housing bubble than we did in
           | 2007.
           | 
           | The cause of this was not a fraud or a scam. It wasn't
           | "buffers" or anything like that. It was incompetence. Nobody
           | wants to admit that, because anyone could have asked the
           | question, what does a credit default swap do to a bank's
           | incentive to vet creditworthiness? But they didn't.

       | How is DeFi doing lending rates ?
       | 
       | Edit: got it, over collateralized with valuable collateral
       | confiscated rather than promised so not fit for the same purposes
       | as normal consumer loan. You wont pay your daughter's sweet 16
       | mega party in mexico or your son's wedding in Singapore or your
       | first car in France with a DeFi loan :D So it's not exactly
       | decentralized finance, it's more decentralized leverage, I guess.
       | At least you cant default a DeFi loan, which sounds reassuring on
       | paper.

         | 
         | The rates are determined the ratio of all stablecoin liquidity
         | provided vs the amount actually borrowed. Liquidity providers
         | can remove liquidity at any time, and so the smaller the
         | remaining liquidity buffer gets, the higher the fees gets.
         | 
         | Most of the rates are dynamic: i.e. the interest rate on your
         | existing loan can increase drastically if there is a liquidity
         | crunch. In practice your interest is charged as though it was
         | extra borrowing and so lowers your liquidiation threshold.
         | 
         | On the flip side, the dynamic rate also means that as the
         | liquidity gets thinner, the interest rate paid to liquidity
         | provider gets higher, meaning it incentivizes liquidity
         | deposits when they are most needed.

           | 
           | The crucial difference is in a mortgage loan the borrower
           | keeps the collateral and gets to use of it, e.g. live in it,
           | while they pay off the loan, whereas in a DeFi "loan" the
           | lender has to keep the collateral the whole time.

             | Surely the DeFi loan should be a "smart contract" that just

               | 
               | But you can do other stuff. For example you could covert
               | ETH to one of the many tokens that represent staked ETH
               | (rocketpool rETH for example) and use that as collateral.
               | Now you are have collateral and staking revenue with the

               | and 3) it needs to be kept in custody by a third party
