ZK-Rollups is one of the most discussed and most interesting topics among the various Ethereum Layer 2 scaling solutions. As mentioned above, we are talking about a solution that is still under development but has very interesting potential. The basic idea, as in all layer 2 solutions, is to increase scalability through processing large amounts of computed data (transactions) in a single transaction. Take that advantage zKtube already But all these things must be done to optimize communication between nodes in the network. The industry did not have an effective solution, so to do that, ZKTube was born.

What is Zktube?

The zkTube protocol is an Ethereum Layer 2 scaling solution based on ZK Rollup technology. All funds are held by smart contracts on the main chain. zkTube performs calculations and storage off-chain, and the efficiency of its sub-chain is proven by zero-knowledge.

In the zkTube network, users can perform various transactions and transfer functionality of ERC20 tokens in the wallet with TPS 3000+, real-time arrival and the same security guarantee of the Ethereum Mainnet level. This premium and smooth experience cost per transaction gas fee is 200 times lower than existing Ethereum Mainnet.
