May 19, 2022. The Ethereum Foundation released the 35th edition of its "Finalized" consensus-layer newsletter Thursday, authored by head of research Danny Ryan.

The update highlighted two separate funding efforts targeting different timelines: a quadratic funding round for Ethereum staking public goods projects backed by a matching pool exceeding $350,000 DAI, and a request for proposals for data availability sampling (DAS) research carrying up to $1.5 million in available grants.

The Staking Round

ETHStaker and clr.fund jointly launched the staking-focused quadratic funding round on May 6, with contributions open through May 24. As of Thursday, five days remained. The minimum contribution is 1 DAI, a deliberate choice to reduce participation barriers. The round runs on Arbitrum, a Layer 2 network built on top of Ethereum, marking the first time clr.fund has operated a funding round on an L2. The matching pool exceeds $350,000 DAI, the largest in clr.fund's history.

Quadratic funding distributes matching dollars based on the square root of individual contributions, weighting broad community participation more heavily than concentrated donations. A project backed by 500 small donors receives proportionally more in matching funds than one backed by five large ones. The model, formalized in a 2019 paper co-authored by Vitalik Buterin, Zoë Hitzig, and E. Glen Weyl, is designed to approximate community preference and limit the influence of concentrated capital.

The round uses MACI 1.0 (Minimal Anti-Collusion Infrastructure), developed by the Ethereum Foundation's Privacy and Scaling Explorations team. MACI applies zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge) to encrypt individual votes. Even if a briber offers payment for a specific vote, the voter can submit a key change that silently overrides the recorded choice, making collusion economically impractical to verify.

The organizing teams framed the initiative around the network's current transition. "We hope to give some of the public goods infrastructure for the Ethereum staking ecosystem the additional and critical support they need as we all collectively push toward the merge and beyond," the joint ETHStaker and clr.fund team stated.

The DAS Research Grant

The second item in the newsletter covers a longer-horizon technical problem. The Ethereum Foundation has opened a request for proposals for DAS research, with up to $1.5 million in total funding across accepted proposals. The submission deadline is July 1, 2022. Interested researchers can contact rfp@ethereum.org.

Ryan described DAS plainly: "Data Availability Sampling is a hard but critical problem."

DAS allows network nodes to confirm that block data is accessible without any single node downloading the full block. It works through Reed-Solomon erasure coding, which expands raw data with redundant information so the original can be reconstructed from any 50% of the expanded dataset, and random sampling, where nodes request small random portions to statistically confirm full availability.

The technology is foundational to Danksharding, Ethereum's long-term scaling architecture targeting approximately 30 megabytes of data per block. That figure is well above the 512 kilobytes planned for EIP-4844, a precursor implementation designed to reduce Layer 2 transaction costs by orders of magnitude. The RFP is open to global applicants, including university research groups and independent developers in India, Nigeria, Kenya, and beyond, making the $1.5 million program relevant not only to downstream users in those regions but to researchers there as potential contributors.

According to a16z Crypto, rollups currently direct more than 90% of their fees toward Ethereum Layer 1 data costs.

Why the Access Gap Matters

Both initiatives carry particular weight for developers and users in South Asia and Sub-Saharan Africa, though neither directly resolves the structural barriers those regions face.

Geographic concentration in Ethereum's validator set is substantial. North America and Western Europe together account for roughly 66% of all validators. Asia-Pacific holds approximately 15.8%. Sub-Saharan Africa's validator representation is negligible. Compounding this, approximately 75% of Ethereum nodes are hosted by cloud providers, meaning that even nodes nominally located in the global South often do not represent genuine geographic decentralization. Running a validator requires at minimum a 2TB solid-state drive, a sustained 25 Mbps connection, and up to 2TB of monthly data transfer. In markets where home broadband infrastructure remains constrained, solo staking is not a practical option for most households.

The staking QF round prioritized projects improving accessibility, safety, user experience, and decentralization. Lightweight clients, non-English documentation, mobile-compatible staking interfaces, and staking pool tooling were among the eligible project categories. Using Arbitrum for the round itself also reduces the cost of participating in funding decisions for contributors with limited capital.

On the fee side, Chainalysis data shows India led global crypto adoption between 2022 and 2024, while Sub-Saharan Africa saw 52% year-over-year growth in crypto activity between 2022 and 2023, driven largely by stablecoin remittances. For users transacting in Indian rupees, Nigerian naira, or Kenyan shillings, marginal transaction costs are a real constraint. The DAS research program is years from deployment, but it sits upstream of the technology that could reduce rollup fees by an order of magnitude or more.

What Comes Next

As of May 19, 2022, the picture is this. The Merge, Ethereum's transition from proof-of-work to proof-of-stake, has not yet been scheduled for mainnet. The transition is more precisely a merging of the existing execution layer with an already-live consensus layer: the Beacon Chain, Ethereum's proof-of-stake layer, had been running in parallel since December 2020, and its 18-month operational track record gave the ecosystem confidence to proceed.

ETH is trading in the $1,800 to $2,200 range, well below the November 2021 peak near $4,800. At current prices, the 32 ETH required to run a validator represents roughly $57,000 to $70,000. In markets like Nigeria or India, where median annual income can fall well below $5,000, that figure represents a prohibitive barrier to solo participation rather than merely a high bar.

Subsequent events filled in the rest of the picture. The staking QF round ultimately closed with 4,704 contributors donating 64,570 DAI. The matching pool expanded to 375,700 DAI, bringing total distributed funds to 440,300 DAI across 21 projects. EIP-4844 shipped as part of the Cancun-Deneb upgrade in March 2024, reducing Layer 2 fees by orders of magnitude. Full Danksharding with DAS remains on the longer-term roadmap.
