Will Vitalik Buterin Transform Ethereum Layer 2s with a Game-Changing Harberger Tax?

Ethereum layer 2 (L2) solutions may benefit from a Harberger tax, as suggested by Vitalik Buterin. However, he emphasized the challenges this tax could present for L2 networks. To address these challenges, Buterin proposed an alternative approach that could be more suitable for enhancing the functionality and economic viability of these L2 platforms.

Buterin’s comments followed a growing demand for the Ethereum Layer 1 (L1) network to implement enshrined fees for L2 solutions. These proposed fees are intended as compensation for the security and traction that L2 networks derive from the Ethereum ecosystem. By establishing a fee structure, Ethereum aims to create a more balanced economic environment that supports both L1 and L2 networks.

The implementation of such fees could incentivize L2 developers and users while ensuring that the L1 network maintains its integrity and security. By generating a steady revenue stream from L2 solutions, Ethereum could enhance its overall ecosystem, fostering innovation and growth within the blockchain space.

Moreover, a well-structured fee system would encourage responsible usage of the L2 networks, potentially mitigating congestion and promoting efficient resource allocation. As the Ethereum ecosystem evolves, the relationship between L1 and L2 will be crucial in determining the network’s scalability and long-term success. By considering innovative solutions like the Harberger tax and enshrined L2 fees, Ethereum aims to navigate the complexities of maintaining a robust and thriving decentralized economy.

The ongoing discussions surrounding these proposals highlight the community’s commitment to finding effective solutions that benefit all stakeholders involved in the Ethereum network.

Vitalik Buterin Considers Harberger Tax On Layer 2

The Ethereum co-founder’s statement on the X platform highlighted the Harberger tax as one that could work following calls to implement an L2 fee mechanism on the Layer 1 network. He noted that this kind of tax could work since it has both “value capture potential that scales with economic activity enabled and low surveillance requirement.

However, Buterin added that the Harberger tax can be challenging for these L2s and goes against their goals of providing stability for their users and applications. The Harberger tax is an arrangement in which these Layer 2 crypto projects pay continuous tax based on their value. As Vitalik Buterin noted, such a plan could disrupt these networks’ ecosystems, especially when they try to undervalue themselves to evade taxes.

Vitalik Buterin also suggested creating an in-protocol to ensure these Layer 2s pay the right amount. However, the Ethereum founder claimed there is no “reliable way” of measuring the execution fees on these L2s.

Buterin further explained that this challenge is equivalent to a government trying to enforce sales tax by only accessing the RAM of digital payment systems. The crypto founder noted that people will find a way to evade the tax in such instances.

A “Softer” Alternative For Tax On Ethereum Layer 2 Networks

The Ethereum co-founder suggested that a softer alternative for tax on L2s could be explored. He proposed the idea of creating a “maximally-neutral-L2 proof aggregation layer,” which will tasked with admitting Layer 2 networks that remit fees to the Layer 1 network. He noted that this mechanism would be supplementary as Layer 2s can opt against joining this aggregation layer and only pay the 500,000 gas per proof, which they currently do.

Vitalik Buterin admitted that he wasn’t sure this plan was a good idea. However, he feels it is the right step if Ethereum wants to build a fee mechanism for layer 2 blockchains. He added that this aggregation layer will also be permissionless to build.

As part of his plans for Layer 2s, the Ethereum co-founder recently stated that he would only publicly support L2s that have reached stage 1 or higher in development. He added that this would apply to every project, regardless of whether he was personally invested in it or if it belonged to his close associates.

At the time of writing, ETH price is trading at around $2,400, up over 3% in the last 24 hours. Trading volume is up over 27% during this period. Ethereum price is facing backlash as Ethereum Foundation and Vitalik Buterin have been alleged to be selling ETH.
