Happy Pi Day guys... today is a Pi π day - 3.14
Happy Pi day!
So here’s thought what if all the Bitcoin mining rigs starts calculating the value of Pi just for 10 minutes? How much can we calculate? Keeping in mind (in early 2020) the computers on the bitcoin network were calculating close to 120 exahashes per second.
And for a reference “One terahash is a trillion hashes per second, one petahash is a quadrillion hashes per second, and one exahash is one quintillion hashes per second (a one followed by 18 zeros).”
Bitcoin mining hardware is restricted to a single use. That is the meaning of “ASIC”: Application-Specific Integrated Circuit. A Bitcoin mining ASIC can only perform the inner-loop calculation for mining Bitcoin. It cannot be repurposed for anything else.
The inputs to the ASIC chips are a 32 byte midstate, the last 4 bytes of the merkle root, a 4 byte timestamp, and 4 byte "bits" (target/difficulty).
