Economic activity of Chainlink oracle networks in aggregate has been steadily increasing since mainnet launch on May 30th, 2019. This is due to a combination of fluctuations in the price of the ERC677 token LINK (used to request data from nodes), an increase in active nodes, and an expanding array of oracle networks.

In total, node payments have increased from $400 of LINK per day to approximately $7,000 of LINK per day, a growth of 17.5x. Active node count has increased from three to 31, a growth of 10.33x. Payments per day have become more volatile as oracle networks can update on a static schedule (e.g. hourly, daily) and/or now a deviation based schedule (e.g. 1% deviation since last update). This chart shows the LINK payments to each node per day, multiplied by the LINK/USD close price each day.
