How was zkTube born?

As we all know, Ethereum 1.0 mainnet attracted numerous applications to be built on it by virtue of its strong consensus and security. However, as the continuous development of the whole ecology, high delays and high GAS fees become the biggest impediments to its growth in turn. When the deployment of Eth2.0 still needs several years for completion, and its improvement to the underlying scalability of Ethereum are yet to be tested, the Layer2 capacity expansion scheme has been proposed at the right moment. By transferring some workload on chain to the off chain, there will have opportunities to quickly realize people’s expectations for Ethereum’s low fees, high throughput, and a good user experience.

What is zkTube?

ZkTube is a Layer 2 protocol based on K Rollup (Layer 2 capacity expansion scheme with the zero-knowledge proof). In terms of token trading under the ERC20/ERC721 protocol, it can greatly reduce the transaction cost, and achieve the throughput 200 times than that of Layer1. ZkTube will become a satisfactory solution for application scenarios with higher requirements on the transaction delivery, timeliness, and high-throughput Dapp.

Who is builds zkTube and the use of zkTube?

ZkTube is an ETH Layer 2 capacity expansion solution launched by Australian team zkTube Labs. It was forged based on ZK Rollup architecture. It can not only realize the VISA-level tps of thousands of transactions per second, but can also fully guarantee the security and privacy of capitals on blockchain and Layer 1 accounts. Compared with other similar capacity expansion solutions, it can realize a faster trading speed. These characteristics of zkTube attract much attention, and it has gradually become one of the promising ETH capacity expansion solutions. After the main network of zkTube is launched, it will provide users and merchants of apps established based on zkTube protocol with underlying protocol support services and realize better transfer of apps and contracts on Layer 1. ZkTube aims to build ETH Layer 2 ecosystem.

Our advantages

Low Gas fee and high throughput

ZKTube protocol will set a block size as 12M, a theoretical throughput of 3,000 +TPS, and the cost of single transaction less than 2% of that for the corresponding operation on L1.

Safety guarantee at the level of Ethereum mainnet

On the zkTube network, the massive calculation and data storage operations will be processed on L2. And then, a large number of transactions will be summarized and packed into a single block and the zero-knowledge proof is generated, then all of them will be sent to L1 for verification, which not only improves the transaction processing speed of the whole network, but also ensures security.

Quick Transaction Verification

On the zkTube network, when the block with SNARK proof is sent to L1 for smart contracting and passes the verification, all transactions in this block will be confirmed, which only takes about 10min from submission to the completion of verification. And this time will be increased to seconds as ZKTube network throughput increases in the future.

Transfer payment received in a real time

On the zkTube network, it takes about 10min for the transaction to become the final confirmation state, but this doesn’t affect the normal use of L2. Users only need to adjust the balance contained in the Token leaf node in their account trees when conducting the transfer operation, so the transfer payment between L2 can be received in a real time.
