According to project leader Nir Magenheim, the system&#8217;s architecture allows for on-the-fly logic implementation.<\/p>\n<p>The following features become available:<\/p>\n<ul class=\"wp-block-list\">\n<li>intra-block credit \u2014 users can obtain unsecured loans within a single block, provided they are repaid before finalization;<\/li>\n<\/ul>\n<ul class=\"wp-block-list\">\n<li>state-aware pre-computation \u2014 conducting complex operations during the assembly phase based on the precise state of the network. Developers claim this approach reduces fees and enhances overall system stability;<\/li>\n<\/ul>\n<ul class=\"wp-block-list\">\n<li>execution-time external data access \u2014 real-time integration of off-chain information during execution;<\/li>\n<\/ul>\n<ul class=\"wp-block-list\">\n<li>deterministic transaction placement \u2014 ensuring transactions are executed in a strictly defined sequence.<\/li>\n<\/ul>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;This allows for block-level guarantees, not just within smart contracts. For instance, applications can be developed that require significant funds for a few seconds, strict operation sequences, or complex computations unsuitable for direct on-chain execution,&#8221; Magenheim emphasized.<\/p>\n<\/blockquote>\n<p>He stated that these new features will enable the development of more advanced trading strategies, efficient DeFi protocols, and a new type of decentralized applications.<\/p>\n<h2 class=\"wp-block-heading\">Business Model<\/h2>\n<p>The Eureka project is based on the <a href=\"https:\/\/forklog.com\/en\/news\/what-is-on-ethereums-roadmap\"><span data-descr=\"Proposer-Builder Separation\" class=\"old_tooltip\">PBS<\/span><\/a> architecture within the Ethereum network. In this concept, block formation is handled not by validators, but by a separate category of participants \u2014 specialized builders.<\/p>\n<p>Magenheim is confident that over time, these operators will become a new execution layer for the blockchain, similar to how smart contracts once expanded the network&#8217;s basic capabilities.<\/p>\n<p>The startup&#8217;s business model is built on collecting fees from transactions added to the formed blocks.<\/p>\n<p>Eureka&#8217;s headquarters are in Tel Aviv, and the team consists of 12 people. The company recently opened a research center in Poland and is now actively expanding the staff of both divisions.<\/p>\n<p>According to Rated Network data, the project began operations in December 2024 and has already become the fourth-largest Ethereum builder by the number of blocks created. However, the company&#8217;s market share remains modest at 1.5%, while nearly 96% of the segment is controlled by niche leaders: Titan Builder, BuilderNet, and Quasar Builder.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"668\" src=\"https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-1024x668.png\" alt=\"Builders\" class=\"wp-image-277360\" srcset=\"https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-1024x668.png 1024w, https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-300x196.png 300w, https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-768x501.png 768w, https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-1536x1002.png 1536w, https:\/\/forklog.com\/wp-content\/uploads\/img-b5c9026e84fdc603-29868110408986-2048x1337.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Ethereum block producers ranking.
