Optimism is a fast, stable, and scalable L2 blockchain built by Ethereum developers, for Ethereum developers. Built as a minimal extension to existing Ethereum software, Optimism’s EVM-equivalent architecture scales your Ethereum apps without surprises.

What is a Layer-1 blockchain?
A Layer-1 blockchain is the base level of the blockchain architecture.
Layer-1 blockchains validate and execute transactions without support from another network, and reimburses transaction fees with cryptocurrencies.
For example, Ethereum runs transactions without depending on an external system and has its own native cryptocurrency, Ether.

SushiSwap is a software running on Ethereum that seeks to incentivize a network of users to operate a platform where users can buy and sell crypto assets.
Overall Stats
Things that can be understood by viewing the charts above;
-
As we can see in the first chart, the number of transactions and users in the Ethereum network is much higher and this difference is significant which indicates the popularity of this network among users and of course active users.
-
The rest of the charts are for fee display. Viewing the charts shows that the fee in all charts, both Total and Average fee, is higher in the ETH network. However, what is noteworthy is the amount of USD fee compared to ETH fee, which USD fee is much higher and this value is 14.0157 B in the ETH network and 20.37475 M in the OP network.
In the above three charts, despite the fluctuations, the number of swaps, transactions and active users in ETH network is more than Op.
-
The highest amount of ETH swap is May 12 and its number is 19.464 k The maximum value for Op swap Jun2 is 303.
-
The highest amount of ETH transaction Jul 24 is 1.090M and Op transaction May 31 is 248.367k.
-
The highest number of active users for the ETH network is 405,456 k on Jun 27.
\
- The trends in the two cumulative number of transaction and users charts are completely similar and in both charts the number of ETH is much more than op.
- The number of Eth transactions and users reached the highest level on 20 October.
Summary of this dashboard;
-
Comparing ETH with Optimism in general statistics such as number of active users, total transactions and the like does not make sense because Ethereum is much older, bigger and more complete than Optimism, which is a new chain. As we can see by looking at the charts, Ethereum is really owns Op in all factors.
-
Tuesday and Saturdays are the most popular days for Ethereum users but Wednesdays are the most popular weekday for Optimism .
-
The average and median fees generated by Optimism transactions are much lower than Ethereum. This number is even higher in terms of daily average fees generated on the chains. Over the last year (especially after the EIP1559 upgrade as well as the (slight) integration upgrade) transaction fees on Ethereum have dropped significantly, but still not as low as hoped. In addition, there are more feature updates that will lead to lower transaction fees on Ethereum.
-
In the number of transactions and active users, there is an increasing trend in Optimism activity over time, while there is an almost constant trend line for Ethereum (especially in recent months).
-
Sushiswap activity in Optimism increases very little over time and has a very low growth rate.
-
It is clear that Ethereum is much more active on Sushiswap than Optimism and its average transactions are much higher than Optimims. Optimism has very little activity in Sushiswap to the point where its activity and stats are much lower than other L2s like Polygon and Arbitrum.
