block & blockchain size

Legend - Green area is total computer memory required to host entire network ledger; Blue line is average transaction data in each chain's block:

block & blockchain size explained

Building upon the elegant interweaving of incentivized mining for network security, confirmation of the data and transactions on the distributed ledger by the nodes, and the constant adjustment of the network difficulty by the protocol allowing for predictable block generation times, we start to get a picture of what is graphed above: the blockchain.

Showing various networks' entire history, graphed above are the average memory sizes of each generated block per day (right axis), and the total size of the blockchain over time (left axis).
