Ethereum is undergoing one of the most important architectural shifts in its\u00a0history.<\/p>\n
This isn\u2019t about scaling.
It\u2019s about power, specifically who controls block production and transaction inclusion.<\/p>\n
Two proposals sit at the center of this\u00a0shift:<\/p>\n
ePBS (Enshrined Proposer-Builder Separation)<\/strong> EIP 4844 discussion<\/a>FOCIL (Fork-Choice Enforced Inclusion Lists)<\/strong> Ethereum research\u00a0forum<\/a><\/p>\n Together, they change how power flows inside Ethereum\u2019s block production pipeline.<\/p>\n And that matters more than most upgrades.<\/p>\n To most users, Ethereum feels simple. Behind the scenes, block production is far more\u00a0complex.<\/p>\n Today\u2019s ecosystem involves:<\/p>\n Validators Ethereum validator guide<\/a>Block builders Flashbots overview<\/a>MEV searchers MEV explained<\/a>Relays MEV-Boost explanation<\/a><\/p>\n This system exists largely to extract MEV (Maximum Extractable Value)<\/strong>, profit derived from controlling transaction ordering.<\/p>\n MEV isn\u2019t inherently bad. Arbitrage and liquidations naturally create economic opportunities.<\/p>\n The issue is industrialization.<\/p>\n Over time, specialized builders developed massive infrastructure advantages. Validators began outsourcing block construction to them. Relays became gatekeepers. A small number of builders now produce a large share of\u00a0blocks.<\/p>\n We saw this clearly after the U.S. sanctioned Tornado Cash. Some MEV-Boost relays began filtering transactions to comply with OFAC requirements. Suddenly, censorship wasn\u2019t theoretical. It was measurable source<\/a>.<\/p>\n When block production concentrates, neutrality weakens.<\/p>\n And neutrality is Ethereum\u2019s core promise credible neutrality discussion<\/a>.<\/p>\n Right now, proposer-builder separation exists socially through tools like MEV-Boost MEV-Boost guide<\/a>.<\/p>\n That means:<\/p>\n Builders assemble\u00a0blocks.Validators pick the most profitable one.Relays act as intermediaries.<\/p>\n It works, but it relies on trusted infrastructure and voluntary coordination.<\/p>\n That creates structural pressure\u00a0points:<\/p>\n Relay concentrationBuilder dominanceRegulatory filteringValidator dependency<\/p>\n Ethereum\u2019s answer isn\u2019t policy or social coordination.<\/p>\n It\u2019s protocol design Ethereum protocol development<\/a>.<\/p>\n Enshrined Proposer-Builder Separation (ePBS)<\/strong> formalizes builder competition inside Ethereum\u2019s consensus layer Ethereum research forum:\u00a0ePBS<\/a>.<\/p>\n Instead of relying on external relays and off-chain agreements, block building becomes a native protocol function.<\/p>\n What changes?<\/p>\n Builders compete directly at the protocol\u00a0levelValidators no longer depend on trusted\u00a0relaysBlock auctions become transparent and enforced by consensus rules<\/p>\n This doesn\u2019t eliminate MEV. Today\u2019s PBS works because of social coordination. That\u2019s a meaningful difference.<\/p>\n If ePBS addresses economic centralization, FOCIL (Fork-Choice Enforced Inclusion Lists)<\/strong> tackles political risk FOCIL research discussion<\/a>.<\/p>\n Under the current model, a builder can refuse to include certain transactions. That refusal could be driven by compliance policies, regulatory pressure, or internal risk controls.<\/p>\n FOCIL changes the incentives.<\/p>\n It allows randomly selected validators to submit mandatory inclusion lists. Builders must include these transactions for their blocks to remain valid under fork choice\u00a0rules.<\/p>\n In simple\u00a0terms:<\/p>\n No single builder can unilaterally censorCoordinated filtering becomes significantly harderTransaction inclusion gains protocol-level backing<\/p>\n Ethereum moves from hoping builders act neutrally to structurally reducing their ability not\u00a0to.<\/p>\n ePBS prevents block-building monopolies.FOCIL prevents transaction censorship.Together, they reduce both economic and political centralization inside block production.<\/p>\n This isn\u2019t about making blocks\u00a0faster.<\/p>\n It\u2019s about distributing power.<\/p>\n Individually, each proposal improves a different layer of the\u00a0system:<\/p>\n ePBS decentralizes who constructs blocksFOCIL protects what must be included in\u00a0them<\/p>\n One addresses market concentration Combined, they reshape Ethereum\u2019s internal power\u00a0balance:<\/p>\n Builders can\u2019t quietly\u00a0dominateValidators can\u2019t easily\u00a0colludeInfrastructure providers can\u2019t act as hidden gatekeepers<\/p>\n That strengthens credible neutrality<\/strong> discussion on neutrality in Ethereum<\/a>., the idea that the protocol doesn\u2019t discriminate between users or transactions.<\/p>\n And that neutrality must be enforced structurally, not socially.<\/p>\n Ethereum is still scaling, including rollups, danksharding, and modular architecture Ethereum scalability overview<\/a>.<\/p>\n But scaling secures performance. As crypto infrastructure matures and intersects with regulators, institutions, and global finance, neutrality becomes a harder engineering problem, not just a philosophical one.<\/p>\n These proposals acknowledge that\u00a0reality.<\/p>\n Ethereum isn\u2019t just a chain for speculative tokens.<\/p>\n It underpins:<\/p>\n Stablecoins USDC, DAI use\u00a0cases<\/a>DeFi markets DeFi\u00a0Pulse<\/a>On-chain lending Compound\u00a0protocol<\/a>Governance systems\u00a0MakerDAO<\/a><\/p>\n If transaction inclusion becomes filterable at the block level, stablecoins can be indirectly restricted. DeFi protocols can inherit censorship risk. Financial coordination becomes dependent on infrastructure compliance.<\/p>\n Neutral base layers\u00a0matter.<\/p>\n Block production is not just a technical detail. Block production is\u00a0power.<\/p>\n Transaction inclusion is\u00a0power.<\/p>\n The entity that controls those processes shapes the political economy of the\u00a0network.<\/p>\n With ePBS and FOCIL, Ethereum is redistributing that power inside its own architecture.<\/p>\n Not through governance debates. Most users will never\u00a0notice.<\/p>\n But long-term resilience often depends on changes like these, quiet, structural adjustments that reduce single points of control before they become systemic\u00a0risks.<\/p>\n Credible neutrality isn\u2019t automatic<\/strong> Ethereum research on neutrality<\/a>. And Ethereum appears to be taking that seriously.<\/p>\n Ethereum Is Quietly Redesigning Block Power: What ePBS and FOCIL Actually Change<\/a> was originally published in Coinmonks<\/a> on Medium, where people are continuing the conversation by highlighting and responding to this story.<\/p>","protected":false},"excerpt":{"rendered":" Ethereum Is Quietly Redesigning Block Power: What ePBS and FOCIL Actually\u00a0Change Ethereum is undergoing one of the most important architectural shifts in its\u00a0history.
