Energy Wallet

Create inter-blockchain wallet that exchanges based on difficulty of blocks, and associated expected energy to mine
  [vote for,

Each cryptocurrency unit represents a very different amount of energy used to mine it, but currently they are traded as if they are equal, in most cases... This creates socio-economic crypto-inequality. Wallets trick people by not showing invested energy (kWh), but could easily be modified to do so.

Idea: universal wallet that works for all coins based on electricity energy invested as universal inter-currency exchange rate...

       Personally I'm still confused about where the original / core (or base) value comes from for most crypto currencies.. but then I'm still more comfortable with gold sovereigns than this newfangled paper stuff :)

       The term Cryptocurrency makes me think of old mouldy Confederate bills somehow creeping their way back into circulation.   

       Like using the word Zombinfrastructure.   

       //represents a very different amount of energy used to mine it//   

       If that's true, then why are you sitting here, and not busily arbitraging that difference away for fun and profit?

       Similar to H.G.Wells's concept of the "Air Dollar" in The Shape Of Things To Come, where currency was "backed " by the average unit cost of international air freight.

       [ ] "difficult to procure" is generally held to be a personal value : why would it be valuable to somebody else ?

       What percentage, of the kWh stated, is to calculate the difficulty of the bit transaction's actual mining cost? Maybe some shopping round needs to be done.

       There is a small amount of energy, called the Von Neumann-Landauer Limit, or Landauer Limit, which sets the theoretical minimum amount of energy required to flip a bit in an ideal, theoretical computer system - "No irreversible computing device can use less energy than this, even in principle".

This limit can be used to show the average amount of energy that would be required for a brute force attack - "...in order to simply flip through the possible values for a 128-bit symmetric key (ignoring doing the actual computing to check it) would theoretically require 2^128 − 1 bit flips on a conventional processor. If it is assumed that the calculation occurs near room temperature (~300 K) the Von Neumann-Landauer Limit can be applied to estimate the energy required as ~10^18 joules, which is equivalent to consuming 30 gigawatts of power for one year" (see link).

This approach could be used to calculate the 'cost' of a cryptocurrency unit - i.e. it would be the bit length of the numbers used in the 'coin', multiplied by the minimum energy for flipping a bit implied by the Landauer Limit.

       [Skewed], me too. And that's why this idea, it's basically, to beat the unreasonable prices.   

       Just because some crackpot wrote that 1kWh buys 1 BTC today, and it will exponentially less, as the system is adopted by more people, because they will compete for same interval of time, is a Ponzi scheme element.
Mindey, Dec 01 2017

       //Von Neumann-Landauer Limit// But that only applies to irreversible computation. If you're prepared to let your computer sort of slosh backwards and forwards through a calculation, until it happens to go all the way through and produce an answer, the Limit no longer applies.   

       I know this to be the case because, when required to produce a complex Excel spreadsheet, I have found it's much less effort to just fudge the answer, then go back again and correct it if anyone complains.
