Eclipse will use Solana\u2019s tech stack for its upcoming mainnet launch, the Ethereum layer-2 network project announced. Eclipse\u2019s mainnet is expected to go live before the end of the year.<\/p>\n
By design, a blockchain stack contains four different layers: execution, settlement, consensus and data availability.<\/p>\n
Blockchains, such as Bitcoin, Ethereum and Solana, carry out all these tasks in a single layer. This means that when a transaction is made, the blockchain executes, settles, reaches consensus, and ensures data availability all within the same layer.\u00a0<\/p>\n
Modular blockchains, on the other hand, are designed to focus on specific tasks.\u00a0<\/p>\n
Neel Somani, founder of Eclipse, notes that he believes all layer-2s \u2014 validiums, optimiums and zk-rollups \u2014 should be considered \u201cmodular blockchains.\u201d\u00a0<\/p>\n
\u201cAt a minimum, they\u2019ve all separated execution from settlement,\u201d he said.\u00a0<\/p>\n
Notably, Eclipse will use Solana<\/a> Virtual Machine (SVM) for execution on its upcoming mainnet. The execution layer is the blockchain layer that holds the code and rules of a transaction; it enables transaction signing and smart contract execution.\u00a0<\/p>\n On Ethereum<\/a>, for example, transactions are executed sequentially. On Solana, however, there is a parallel execution environment. This means that more transactions can be processed at a lower cost.\u00a0<\/p>\n \u201cThat\u2019s probably the biggest difference,\u201d Somani said. \u201cAnother benefit is the \u2018local fee markets,\u2019 meaning if one application gets a ton of activity, it doesn\u2019t impact fees for other apps. It is a smaller set of \u2018opcodes,\u2019 and it\u2019s register-based which makes [zero-knowledge] proving easier.\u201d<\/p>\n Elsewhere, Eclipse will use Risc Zero<\/a> for proving. Settlement, like most rollups today, will take place on Ethereum \u2014 meaning that it will utilize Ethereum\u2019s security properties to validate transactions. Data availability (DA) will be derived from Celestia.\u00a0<\/p>\n Read More:<\/strong> Why data availability sampling matters for blockchain scaling?<\/a><\/p>\n Unlike many rollup solutions today, Celestia\u2019s DA layer utilizes Data Availability Sampling (DAS) over having a Data Availability Committee (DAC), meaning there are fewer trust assumptions.\u00a0<\/p>\n That said, the team at Eclipse will continue to keep a close eye on Ethereum\u2019s EIP-4844 upgrade<\/a> and consider migrating to Ethereum\u2019s DA in the future.\u00a0<\/p>\n \u201cIt\u2019s become clear that the single-threaded EVM is not sufficient to scale Ethereum, which is why apps are turning to their own app-specific rollups,\u201d Somani told Blockworks. \u201cYet even the most sophisticated designs like Arbitrum are now seeing fee spikes \u2014 and it\u2019s all because of the lack of parallelism and local fee markets.\u201d<\/p>\n
