INTRODUCTION

What Is Optimism (OP)?

Optimism (OP) is a layer-two blockchain on top of Ethereum. Optimism benefits from the security of the Ethereum mainnet and helps scale the Ethereum ecosystem by using optimistic rollups. That means transactions are trustlessly recorded on Optimism but ultimately secured on Ethereum.

Optimism is one of the biggest scaling solutions for Ethereum with over $300 million in TVL. It is home to 35 protocols, the biggest being Synthetix (SNX), a derivatives exchange, Uniswap (UNI), a DEX, and Velodrome (VELO), an AMM. Users can begin their journey on Optimism by adding the chain on their Metamask and bridging tokens like ETH to the L2. On May 31, 2022, Optimism conducted a highly anticipated airdrop of its OP token. The airdrop was so popular that it briefly slowed down the Optimism blockchain.

What Makes Optimism Unique?

Optimism is designed around four core tenets:

• Simplicity
• Pragmatism
• Sustainability
• Optimism

Optimism aims for the minimum number of moving parts while building a layer-two solution for Ethereum. In practice, this means using proven Ethereum code and infrastructure when possible. Optimism thus aims to keep its code as simple as possible and work directly with existing codebases.

The ecosystem further emphasizes pragmatism and is driven by the real-world needs and constraints of its own team and the users engaging with the ecosystem. Hence, Optimism aims to build iteratively and implement features like EVM equivalence gradually.

Optimism's design process is built around the idea of long-term sustainability and not taking shortcuts to scalability. That is why it uses optimistic rollups and takes advantage of the consensus mechanism of Ethereum to scale the network. Blocks are constructed and executed on the L2 (Optimism), while user transactions are batched up and submitted to the L1 (Ethereum). The L2 has no mempool, and transactions are immediately accepted or rejected. This guarantees a smooth user experience while ensuring security through the Ethereum consensus mechanism.

Transactions are submitted to Ethereum without direct proof of validity and can be challenged for a certain period of time (currently seven days). After that, a transaction is considered final. That is why withdrawals from Optimism to Ethereum take seven days to complete.

CONCLUSIONS

As we can see in the first two graphs, we have analyzed the average number of swaps per wallet in uniswap and it gives us a result of 14.17, and also in the second graph we have analyzed the average volume swapped by each wallet and it has given us a result of 20.8k. \n In the third graph, we have compared the number of wallets swapping by day since June and we see that sushiswap has much more reaching 4752 swaps at its maximum, a clear difference vs uniswap that does not reach 50. \n In the fourth graph, sushiswap also stands out in number of swaps reaching 12,30k swaps vs the 50 of uniswap. \n In the fifth chart, we have analyzed the top 10 pairs with respect to number of swaps in Uniswap and we see that the most outstanding pair is usdc-weth with more than 45,77k, in second place we have weth-usdc with 41,68k. \n In the sixth graph, we have analyzed the total swap count on velodrome, uniswap and zipswap, and we can conclude that uniswap is the one with the highest count with a total of 367,762 followed by velodrome with 313,470. \n Finally in the last graph we have analyzed the total unique swappers count, and also uniswap is outstanding with more than 38,944 and velodrome with 7338. \n
