The full launch of the solution for scaling the second level of Optimism will lead to a hundredfold increase in the throughput of the Ethereum network, co-founder of the project Vitalik Buterin expects. In a recent podcast, he stated that developers are keen to merge the existing Ethereum chain with the new Ethereum 2.0 system, but are confident in the ability of the second layer solutions to balance the load until this is done.
“The roll-ups are coming very soon. We are fully convinced that by the time additional scaling is required, sharding will be ready for a long time, ”he said.
Roll-ups allow you to process and store data in separate sidechains, and then record changes in the main chain at a time. According to Buterin, such scaling will be sufficient to solve the problem of congestion in the main chain in the medium term, after which a more advanced solution based on sharding technology will be finalized.
“Do not forget that the presence of roll-ups in the absence of sharding provides a hundredfold scalability. This opens up opportunities to increase throughput up to 1,000 to 4,000 transactions per second, depending on how complex those transactions are, ”he added.
According to Buterin’s expectations, the launch of the Ethereum virtual machine (EVM) in Optimism will take place in about a month. This will allow rollups to be used in decentralized finance applications. It is assumed that Optimism may be involved in the forthcoming version of the Uniswap decentralized exchange protocol.
“There were simpler roll-ups that only allowed simple asset swap transactions, such as Loopring and zkSync. These roll-ups have been working steadily for about a year, so roll-ups are not just a theory. They have been a practical part of scaling Ethereum to a small number of users for almost a year now, ”said Buterin.
At the beginning of the week, the developers revealed the details and date of the next Ethereum hard fork – Berlin.
