Currently, Nautilus Chain is preparing for the final stage before the mainnet launch. It is reported that the chain has updated a new testnet and carried out a new technical upgrade based on the previous version of the testnet. The latest testnet version is closer to the technical plan of ecological development. This testnet upgrade will be the last iteration of the testnet version, and it will be launched on the mainnet after the test is completed.

The following is the updated test network information:

Chain name：Proteus Testnet

Chain id：88002

RPC：https://api.proteus.nautchain.xyz/solan

Faucet：https://faucet.proteus.nautchain.xyz/request_neon

Users participating in the test can set up their wallets with the above test information to conduct a new round of test interactions.

Nautilus Chain is the first modular Layer3 chain in the industry, which allows developers to develop customized applications. Nautilus Chain itself does not use Layer1 such as Ethereum as the root layer. It uses Layer0 facility Celestia as the main basic source of Nautilus Chain modularization. Through Nautilus Chain, developers can directly build a highly customized application layer (not limited to Rollup), and Celestia provides DA.

In addition to DA, Nautilus Chain uses Eclipse as the settlement layer. Based on Eclipse, Nautilus Chain will no longer rely on Layer1 such as Ethereum for system settlement. Based on these components, Nautilus Chain developers can build various "independent" DAPP-Chains or DAPP-Rollups or DAPP-Subnets that can run in parallel from the bottom up, allowing developers to stack different chains into layers to create chain stacks, and no longer need to return to Layer1 in the end. In this process, Nautilus Chain plays the role of a parallel processing layer at the top, which helps to achieve scalability in the execution layer in the EVM environment.

Nautilus Chain is implementing a modular stack of Celestia + Eclipse + zkEVM. With its modular architecture, it has also become the industry's first parallelized and fastest EVM Rollup Layer3 expansion solution, which can encapsulate storage, computing, consensus, etc. in different modules, with higher scalability and expansion capabilities, further improving network throughput and security, and increasing privacy through ZK Rollup technology to further expand richer functions.

Nautilus Chain: Building the fastest zkEVM

Nautilus Chain is also one of the advocates of zkEVM. As the first Layer3 chain with a modular architecture in the industry, it uses Zk-Rollup as one of its main customization solutions. Developers can customize the Zk-Rollup layer based on this solution, and it has many features such as extremely high interoperability and parallel operation, and does not rely on Ethereum Layer1 (mentioned above).

ZK-Rollups is a scalability solution based on zero-knowledge proof technology. Early zero-knowledge proof technology was not developed directly for EVM, so it could not be directly applied to the Ethereum Virtual Machine (EVM) for a long time. At the same time, early Ethereum did not consider ZK at the beginning of its design. ZK not only involves cryptography and mathematics, but also hardware knowledge, so they are not compatible with the execution environment and instruction set of EVM.

As time goes by, some new zero-knowledge proof technologies and tools have emerged, such as ZKP (Zero-Knowledge Proof) and SNARK (Succinct Non-Interactive Argument of Knowledge), which can be better compatible with EVM. With the popularity and application of EVM, EVM has almost become synonymous with the Ethereum ecosystem, representing the developers, applications and tools of the Ethereum ecosystem, so zkEVM has also come into being. Ethereum founder Vitalik Buterin also has high hopes for zkEVM and expressed his hope to let zkEVM enter L1 and build an open multi-zkEVM.

Vitalik Buterin once said in the article, "Today, zkEVM is used for rollup. This increases scalability by allowing expensive EVM execution to occur only a few times off-chain, while others only need to verify the SNARKs published on the chain to prove that the EVM executed the calculation correctly. It also allows some data (especially signatures) not to be included on the chain, saving gas costs. This gives us a lot of scalability benefits, and the combination of scalable computing with zkEVM and scalable data with data availability sampling can allow us to expand further." Zk-Rollup is the best way to build privacy, compliance and other features at the bottom of the chain, and for ZK-Rollup, zkEVM is the best way to be compatible with EVM.

Although Starkware, zkSync 2.0, Polygon, Scroll, etc. are also early advocates of zkEVM, Nautilus Chain has a unique architecture. It is the first modular chain, with storage, computing, consensus, etc. in different modules, which means that it can achieve higher scalability and expansion capabilities. Nautilus Chain is expected to become the first parallelized and fastest EVM Rollup in history. Its advantages are more obvious and more attractive to developers.

This replacement of the new test network will be the last version upgrade of the test network. After this round of test network is completed, the Nautilus Chain main network will be officially launched, and the industry may enter a new Layer3 era.
