Last October, the Uniswap decentralized exchange platform announced its desire to launch its own Layer-2: Unichain. Finally, a few weeks ago she revealed an opening of the Mainnet planned for the beginning of 2025. Something said, something due, Uniswap has just opened the doors of the Mainnet of the Unichain to users.
The key points of this article:
Uniswap opened the Mainnet of his Layer-2 Unichain, based on OP Stack, offering impressive performance with considerably reduced costs.
Unichain is distinguished as the first Layer-2 launched as an internship 1 Rollup, integrating decentralization via evidence of faults without permission and an open validation network.
UNISWAP reveals the unichain Mainnet
The news has just fallen, the giant Underpat the origin of the eponymous DEX opened the Portes du Mainnet de Son Layer-2 Unichain.
As a reminder, this is a Layer-2 evolving in parallel of Ethereum. Under the hood, it is Basé Sur l'on stack. This is the technological battery developed by Optimism and also used by L2 such as base. This allows him to offer impressive performance, with a 1 second block time and costs 95% lower than on Ethereum L1. In addition, faced with the problems of fragmentation of liquidity, theUnichain was built to promote interoperability. Thus, it will soon have a Access to cross-chain liquidity,, and this, natively. This will be done through Superchain, the Conglomerate of Rollups based on OP Stack.
“Unichain will take care of native interoperability when it is put into service on the superchain during the year. Future updates will improve the speed and finality of the blocks, which will help make inter-chain transactions more effective. »»
Finally, the launch of Unichain is supported by a multitude of protocols and service providers. Thus, more than 80 projects have already undertaken to build or carry their protocols on the L2.
Decentralization at the heart of the project
A point particularly distinguished the unichain of its competitors. Indeed, it is the first layer-2 to have the characteristics of internship 1 rollup from its launch. As a reminder, it is L2Beat who defined the various internships of a Rollup. It is a typology that measures the decentralization of a layer-2. L2Beat distinguishes 3 steps, ranging from internship 0 to internship 2. Thus, an internship rollup 1 is a rollup which is governed by smart contracts. However, it still has a Security Council which makes it possible to process and act in the event of bugs. In addition, an internship rollup is characterized by the implementation of a fully functional evidence system, decentralization of the submission of evidence of fraudand the possibility for users to withdraw their funds without coordination with operators.
“Unichain is the first L2 to be launched as an internship 1 Rollup from the first day, and is online with proofs of faults without permission. With the upcoming arrival of the Unichain Validation Network, anyone will be able to operate a UVN node and check blocks. »»
Rollup-BOOST: The Secret of Unichain Performance
At the heart of network performance, we find Rollup-Boosta solution designed in close collaboration with the teams Flashbots. Thus, this solution move the scheduling of transactionsa task traditionally ensured by a centralized sequencer, towards a network of external operatorssuch as flashbots or other specialized companies. This mechanism makes it possible to divide each block into four sub-blocks of approximately 250 millisecondsthus opening the track to times of block less than a second. The gradual deployment of Rollup – Boost in the coming months should therefore pass the Unichain below the 1 second block of Block Time. Without going into too much detail, this will also have advantages for liquidity suppliers and Dex users. Indeed, this allows new forms of arbitration, while ensuring a reduction in the negative impacts of the MEV on end users. On paper, everyone should do well. This approach responds to criticisms concerning the centralization of sequencersby proposing a solution that combines speed, security and decentralization. Definitely, the news is multiplying on the side of Uniswap. Indeed, the company causing the DEX announced last week the Deployment of the V4 of its flagship protocol.
