  • FOCIL aims to prevent an oligopoly of Ethereum validators.
  • Critics fear legal risks for U.S. validators under FOCIL.
  • Buterin's vision: Ethereum as a neutral ”dumb pipe” free from control.

Ethereum's New Proposal: Vitalik Buterin Defends EIP-7805 Against Criticism

Ethereum co-founder Vitalik Buterin responded to criticism of the EIP-7805 (FOCIL) mechanism, a proposal designed to ensure Ethereum's first level (L1) remains a neutral network. This mechanism is intended to prevent the formation of an oligopoly among builders, preserving Ethereum's decentralized nature.

The EIP-7805 proposal was brought to light by user Amin Soleimani. It’s important to note that Buterin himself is the author of the FOCIL concept, which was submitted for consideration in November 2024. Although the proposal is still in draft status and awaiting approval, it has already stirred significant controversy.

FOCIL, aimed at combating Ethereum’s centralization, involves introducing 16 additional validators per slot. One validator would have the authority to determine the order of transactions, although all proposed transfers would still be included in the block.

But Soleimani voiced concerns about the potential risks this could bring to validators, arguing that the implementation of this mechanism would increase legal liabilities, particularly for those operating in the U.S. Ethereum’s anti-censorship measures have so far allowed node operators to avoid the inclusion of transactions involving sanctioned services like Tornado Cash, only delaying their processing rather than excluding them entirely.

Is Ethereum's Neutrality at Risk with FOCIL? The Legal Debate Explained

Soleimani argued that under FOCIL, validators would no longer be able to filter out transactions from sanctioned services. He expressed concern that this could expose U.S. validators to legal risks. Soleimani noted:

Buterin responded to these criticisms by emphasizing that the goal of FOCIL was to protect Ethereum's L1 status as a ”dumb pipe” — a neutral network that only transmits data without controlling it.

Buterin’s Vision: Why Ethereum Must Stay a ‘Dumb Pipe’

Buterin firmly believes that forcing validators to include sanctioned transactions is necessary for Ethereum's long-term health. He stressed that Ethereum's L1 must remain neutral, free from interference by any single entity, including validators. This neutrality is achieved by introducing several safeguards:

  • Ensuring the mempool is stable and functional for simple block creation.
  • Creating non-protocol technologies for distributed block construction.
  • Establishing multiple channels to enable transactions.

FOCIL is one of the latest mechanisms to achieve these goals. Buterin argues that it provides benefits to both validators and attesters, making the latter's work simpler from a technical standpoint.

Can FOCIL Secure Ethereum’s Decentralized Future?

With the potential adoption of EIP-7701, Buterin envisions expanding FOCIL’s capabilities to further eliminate centralized intermediaries. The ultimate goal is to prevent an oligopoly of validators from gaining veto power over which transactions get included in blocks.

In response, Soleimani emphasized that Ethereum was never intended to be a “passive channel.” For him, Buterin’s vision of Ethereum as a neutral pipe is an ideal that fails to reflect the reality of Ethereum’s current status.
