I want to determine the network hashrate as etherscan.io shows.
As I know,difficulty is the times of hashing to find the next block.
So, the sum of difficulty should be the times of hashing in last 12 hours.
So I think this way should be right:
- Sum the difficulty of the last 12 hours
- Div the sum by seconds of 12hours (43200)
It show me that the hash rate should be 219,446 GH/s
But etherscan.io show me that hash rate is 262,744.29 GH/s
What is the difference?
