Looking at the output, we can see that the number of daily active users on the Flow blockchain has varied significantly over the month of March. The daily active users have fluctuated between as low as 269 to as high as 473,290.

There are a few spikes in daily active users that are worth investigating further.

First, on March 3rd, there was a massive increase in daily active users to 98,554, which is significantly higher than any other day in March.

Secondly, on March 14th, there was another significant spike in daily active users to 3,008. This could be due to the launch of a new DApp, a major update to an existing DApp, or a marketing campaign that resulted in a temporary increase in user activity.

Finally, on March 31st, there was a massive increase in daily active users to 473,290. This could be due to a technical issue or an anomaly in the data, as it is significantly higher than any other day in March.

The data reveals a steady increase in the creation of new addresses over time, with a notable spike on March 31, where the number of new addresses reached a staggering count of 473,010 address.

The majority of the days during this period saw more new addresses created than existing addresses interacting with the blockchain. However, on a few occasions, such as March 29 and March 30, the number of existing addresses interacting with the blockchain surpassed the number of new addresses created.

In order to identify what causes the surge of new address, we will find out:

1. What contracts are they interactng with ?
2. How many transactions are made by these new address, and to which contracts ?

How many transactions are made by these new address, and to which contracts ?

Most of the new address in the 31st mArch surge, interacted with FlowFees contract. It is then found out out that most of these address only did tokens withdrawn event.

The scatter plot below shows the distribution of txn count and number of address based on event type. Looking at itm, it reports that most new address only transacted once with tokens withdraw events.

The chart shows that the y-axis as total number of transactions made by new address, and the marker size represents the number of address.

The detail of the transaction count and the total address interacting wih Token_Withdrawn event are listed in the Table below.

What Contracts are the new Addresses interacting with?

All the transaction by the new address seems to interact with the Flow Fees Contract, 0xf919ee77447b7497

The Donut Chart above shows that 99.96% of the total transactions are by the address that transacted once on 31st March. All these transactions have the Event_type of TokensWithdrawn , interacting with FlowFees contract.

To summarize, majority of the new address interacted with the Flow Fees contract. So suffice to say that the sudden surge of new address was not caused by new protocol or NFT launched. After all , the new user growth looks inorganic. Now that we know what these address do when they became activated. Now lets look at the timeframe of new address joining FLOW blockchain.

From the bar chart, it seems the sudden increase of new address began on 00:01 am EST and continues till 23:00 EST. On the next day, there is no new address reported and the surge halted. This does not seem to show an organic user growth, and looks more like system/bug error kind of pattern.

So What is Flow Fees Contracts?

Flow Fees contract is a smart contract on the Flow blockchain that calculates an account's storage capacity based on the amount of reserved Flow tokens and minimum storage reservation. At the end of transactions, the contract checks the storage capacity and main flow token vault against the minimum reservation, and any account that fails the check will cause the transaction to fail.

In conclusion , in the attempt to study Daily ACtive address on FLOW, I have discovered strange hike in new user address, which interacted with Flow Fees Contract. I have been checking the forums , their main web page, their blogs and their twitter page, but nothing about this event has been reported.

Recently, there is an abnormal hike of new address becoming active on the FLOW blockchain for several days. The most significant is on March 31st, where almost 500 K of new address making their first transactions in a single day. It is found that hundresds of address are making one-time transaction every minute on that day. This dashboard outlines the finding of said event.
