Another player came to the crowded Ethereum L2 battlefield.
On March 11, 2024, the Ethereum L2 solution Eclipse of Ethereum using Solana virtual machine (SVM) announced the completion of a $ 50 million Series A financing, led by Placeholder and Hack VC, making its total funding of $ 65 million.
What innovative functions and highlights can it bring to Ethereum L2?This article briefly describes it.
Eclipse: Standing on the giant’s shoulder
Eclipse combines the best part of the modular stack:
Settlement: Ethereum—— ECLIPSE settled on Ethereum (that is, the built -in verification bridge will be located on Ethereum) and use ETH as its GAS token.
Execution: Solana virtual machine (SVM)—— Eclipse will run high -performance SVM as its execution environment.
Data usability: Celestia—— ECLIPSE publishes its data to Celestia to achieve scalable data usability (DA).
Proof: RISC ZERO——EClipse will use RISC ZERO for ZK fraud certificate (not required to serialize the intermediate state).
Ethereum settlement
The verification bridge of the Eclipse main network on Ethereum will be directly built in Eclipse.The Eclipse node will determine the “standard chain” through this bridge.The bridge forced Eclipse to perform correct sorting.The Eclipse node must also run the complete node of Ethereum.The bridge will verify all Eclipse transactions to prevent invalid state.In addition, it can survive and resist review in certain failures. Even if the sorter fails or starts to review it on L2, users can also force their transactions through the bridge.
Eclipse recognizes the importance of Ethereum native assets, so Eclipse will use ETH as GAS token.The Eclipse main network does not plan to have its own tokens.
Eclipse select solana vm
Virtual machine is a software that can run a program.Specifically, the virtual machine executes the smart contract of the blockchain.Why does Eclipse choose to use solanda VM?
-
Performance: EVM blockchain, such as Ethereum, only one program is running at any given point, which is called “single thread”.Solana virtual machine is a highly parallel Runtime. If there are multiple kernels, multiple programs can be run at the same time, thereby significantly increased throughput.
-
Safety: Some languages (such as Rust) can prevent many errors that Solidity cannot prevent.For example, Ethereum smart contracts are vulnerable to the so -called re -attack.
-
Community: Ethereum and Solana popular blockchains have cultivated booming developer communities around EVM and SVM, respectively.Compared with new virtual machines such as Move VM or Fuel VM, this means better tools and developers support.
-
Easy to use: Solidity and other languages are easier to write code, and not all bytecodes support compile from solidity.
In summary, the eclipse main network transportation line is selected from Solana virtual machine (SVM).However, it can also support the program built by the NEON EVM as the Ethereum virtual machine (EVM).In the future, Eclipse will add other bytecode formats according to the requirements of DAPP.You can even use EVM’s existing tools (such as Truffle or Remix) or SVM tools (such as Solana CLI or Seahorse Lang).
Eclipse use Celestia to provide DA
The current bandwidth of Ethereum does not support the target throughput and cost of the Eclipse main network.Even after the EIP-4844 (also known as “Proto-Danksharding”), this is still the case. It provides a Blob space of about 0.375 MB of each block (the limit of each block is about 0.75 MB).
-
For ERC-20 transfers with basic compression (about 154 bytes per transaction), this is equivalent to about 213 TPS.
-
For compression exchange (about 400 bytes per transaction), this is equivalent to all ROLLUP for about 82 TPS.
In contrast, Celestia will launch a 2 MB block later.Once enough data availability sampling (DAS) light nodes are launched and the network is stable, Blobspace is expected to increase to 8 MB shortly after starting.DAS light nodes have two key functions:
-
Users can verify whether the Eclipse block data is available
-
It helps to securely expand the entire network, because as more DAS light nodes are launched, the DA layer can safely increase its throughput.
Celestia’s DAS light node has supported, encrypted economic security attributes, and highly scalable DA throughput from the first day, making it a clear choice for today’s Eclipse main network.Eclipse also intends to monitor Ethereum’s progress in DA expansion after EIP-4844.If Ethereum provides a larger scale for Eclipse to benefit users, Eclipse will evaluate the possibility of migrating to Ethereum DA.
Fraud proved to use RISC ZERO
Eclipse’s main network deploys optimistic Rollup, but is developing zero -knowledge Rollup in parallel.
For optimistic Rollup, the “sorter” sorts the transaction and publishes the generated status with the bounty to the 1st floor of the Ethereum.The “verification” can re -execute the transaction. If there is different opinions on the results, the verifier can challenge the status root through “settlement”.If the verification is correct, the reward will be awarded the verification.
Eclipse uses RISC ZERO to create a ZK fraud proof, without the need to serialize in the middle state.
