Introduction

Polygon is a cryptocurrency, with the symbol MATIC, and also a technology platform that enables blockchain networks to connect and scale. Polygon—"Ethereum's internet of blockchains"— launched under the name Matic Network in 2017.

In this dashboard, we are going to compare transaction cost on Ethereum and Polygon.

Approach

The ethereum.core.fact_hourly_token_prices table is used to get the daily price of ETH and MATIC, the native tokens of Ethereum and Polygon blockchains, which is used to pay transaction fees. The polygon.core.fact_transactions table is used to access polygon transactions and the amount fee paid to be processed, respectively ethereum.core.fact_transactions is used to get Ethereum transactions.

In order to have a more homogeneous and understandable result, we use USD equivalent fees instead of native tokens. As instructed, the comparison has been made since the beginning of July.

Finally, to obtain the correlation between A and B, we use the aggregation function corr(A, B).

corr(A, B) gives a result between 1 to -1:

1 indicates a strong positive relationship.
-1 indicates a strong negative relationship.
0 indicates no relationship at all.

Total Fees

Below is the total amount (in USD) paid in transaction fees per blockchain. During the same period users have paid more than 100x more fees on ethereum network than polygon network.

On the following charts, the total hourly fees paid on each blockchain can also be seen.

With a general look, it can be seen that there is almost no relation.
while sometimes total fees on ethereum has increased, total fees paid on Polygon have mostly stayed the same.
the other difference that can be seen is that, on Polygon, during some hours there is a sharp increase of fees paid, and quickly in the next hour fees return to their average amount, but on Ethereum fees go high and stay high for a few hours.

Correlation

By looking at the charts above, it could be infered that there isn’t much of correlation between them. as already mentioned the CORR(X, Y) function is used to find the correlation between fees.

The total fees and average fees show a number around 0.250 which means a very slight to no correlation between these parameters.
The median and mode fees show no correlation at all, as the number is near 0.

Statistics

The following charts, show the hourly average, median and mode of fees paid on each blockchain. It can be seen that :

Average daily fees have remained mostly around the same numbers on Polygon, while it has increased more aggressively on Ethereum.
Minimum average fee on ethereum has been around $ 0.4 and the maximum has been around $ 11, almost 27x more.
Minimum average fee on polygon has been around $ 0.006 and the maximum has been around $ 0.03, almost 5x more, more stable and a lot cheaper!
The Median and Mode chart have the same story here, Polygon’s case is more stable than Ethereum.
