The Ethereum ecosystem has achieved a significant milestone, reaching an all-time high in combined transactions per second (TPS). According to L2BEAT data, the Ethereum scaling networks, including layer-2 and layer-3 blockchains, processed an impressive 246.18 TPS on June 16, equivalent to approximately 21.2 million transactions daily.

Xai, a relatively new Ethereum layer-3 scaling solution focused on gaming applications, played a significant role in this achievement, accounting for over 41% of the total transactions. Xai's TPS surged from a mere 1 transaction per day to 101.72 TPS on June 16, a remarkable increase. Base and Arbitrum followed closely, with 33 and 21 TPS, respectively. Proof of Play Apex, another gaming-focused Ethereum layer-3 scaler, ranked fourth.

While Xai and Proof of Play Apex boast impressive TPS numbers, their total value locked (TVL) remains relatively small, at $1.38 million and $695,000, respectively. In contrast, Arbitrum One and Base, the largest Ethereum scaling solutions by TVL, secure $18 billion and $7.6 billion, respectively.

Some industry experts argue that TPS is an overrated metric for measuring blockchain performance, as it doesn't consider the value of each transaction. However, it remains the most commonly used metric due to the lack of a better alternative.

In conclusion, Ethereum's scaling solution has achieved a remarkable feat, reaching a new all-time high in combined TPS. Xai's impressive performance has contributed significantly to this achievement, demonstrating the potential of layer-3 scaling solutions. As the Ethereum ecosystem continues to evolve, it will be interesting to see how these solutions impact the network's overall performance and adoption.
