Plots Bitcoin hash rate, miner revenue, and "security factor".
The security factor is also extrapolated out to get an estimate of Bitcoin's relative security in the future.
The security of PoW cryptocurrencies like Bitcoin is proportional to miner revenue.
Miner revenue can then be referred to as the "security budget".
Cost to attack must also scale with network value, so cryptonetworks must maintain a high security factor -- cost to attack as percentage of market cap.
Run one of hash_rate.py, miner_revenue.py or security_factor.py to produce the respective chart.
security_factor.py pulls data from every single Bitcoin block so it will take a while.
Each time the script is run it will check for new blocks and auto-download them.
