Currently, around 30 applications are running on the network, including the trading platform GTE and the prediction market Guess.Best.

According to the developers, MegaETH has achieved a block processing time of 10ms, which is 25 times faster than Arbitrum’s 250ms. In the future, the team plans to implement a proprietary parallelization mechanism to reach 100,000 TPS—a target Vitalik Buterin set for Ethereum L1 in 2021.

Earlier, Santiment analysts reported a decline in optimism regarding Ethereum.
