If the value of ETH drops precipitously relative to BTC, then the dollar value of the ETH bonded by
the signers can be less than the dollar value of the BTC deposit they have backed, meaning they
have positive expected value if they try to steal the BTC.
In order to avoid that, we require that the bonds are overcollateralized. For each ETH they
collateralize, they must put up an additional 50%, for a total of 150% collateralization rate.
