What is the mean number of embedded hashes per Ether?
If my understanding is correct, the Keccak-256 hash function is a fundemental unit of computational work on the Ethereum blockchain. Therefore each new ETH unit must have some number of hashes performed to bring it into existance. I'm interesting in gauging what this value is and how it changes over time:
How has NoHashes/ETH changed over time?
I'm assuming it varies with the Proof of Work target value. I'm am unsure if there was any special mechanism behind the pre-sale which changes the NoHashes/ETH.
How will NoHashes/ETH change when the system changes to Proof of Stake?
