The Protocol Support Team opened applications on December 15, 2022, with a deadline of January 31, 2023. Grants ranged from $500 to $10,000 for custom implementation projects. All funded work was required to be open source. Applications were accepted in English only, a constraint worth noting for the global communities this work ultimately served. The ceremony itself began January 13, 2023, ran for 208 days, and closed August 8, 2023. It ultimately drew 141,416 participants, making it the largest multi-party computation of its kind by contributor count.

What the Ceremony Was and Why It Mattered

The KZG Ceremony is a one-time cryptographic setup sometimes called a "Powers of Tau" computation. It produced a piece of data called a Structured Reference String, which is a required input for the polynomial commitment scheme that powers EIP-4844 (also known as proto-danksharding). The acronym KZG refers to the three cryptographers who designed the underlying scheme: Aniket Kate, Gregory M. Zaverucha, and Ian Goldberg, whose 2010 academic paper introduced the construction. The scheme enables constant-sized proofs regardless of polynomial complexity, which is the technical property that makes it useful for scaling applications.

EIP-4844 introduced a new transaction type called blob transactions. These allow Layer 2 rollups to post data to Ethereum mainnet far more cheaply than the previous method. Blob data is stored temporarily on beacon nodes for roughly 18 days and then deleted, which avoids burdening validators with permanent storage. Without the KZG Ceremony producing a valid output, EIP-4844 could not have been deployed.

The security of the ceremony rests on a straightforward principle: only one participant in the entire process needs to have kept their secret input private and destroyed it afterward. As the Ethereum Foundation explained in its ceremony FAQ, "the ceremony has a '1-of-N' trust assumption, which means that only a single participant in the entire ceremony needs to have not revealed their secret input for everything to be secure." That threshold makes the 141,416-contributor scale highly significant. For a compromise to occur, every single contributor would need to have either colluded or been compromised, or every implementation used would need to contain a flaw. The Ethereum Foundation described this combination of requirements as making the setup "extraordinarily robust."

Two Grant Tracks and What They Funded

The grant program supported two categories of work. The first covered independent, non-browser implementations of the ceremony client. Funding alternative clients reduced reliance on any single software codebase and diversified the potential points of failure. The second category covered unusual entropy contributions, meaning teams that generated randomness through methods that are difficult to fake or intercept. A dedicated special contributions period ran April 1 through 16, 2023.

Among the 14 funded special contributions, several produced particularly notable results. Cryptosat contributed entropy collected from space aboard the Crypto 2 satellite. A team at Mach34 used seismic data generated by detonating four pounds of Tannerite. DSRV Labs, a Korean developer team, built a pure JavaScript client that ran on an airgapped Raspberry Pi 2. Matt DesLauriers sampled Very Low Frequency radio signals from atmospheric noise recorded along the UK coast in a project named the Sferic Project. xofee.eth built a KZG Marble Machine, a 23-sensor contraption that captured the movement of marbles as an entropy source. Stephen Solis contributed via the Calculating Car project, sampling OBD port data from a self-driving module.

These approaches illustrate that protocol-level cryptographic infrastructure work is accessible to developers worldwide, not only those at large Western firms. The DSRV Labs contribution in particular demonstrated that participation requires neither exotic equipment nor specialized languages: a Raspberry Pi 2, JavaScript, and a reproducible methodology were sufficient.

The Fee Impact and Who Benefited Most

EIP-4844 activated as part of the Dencun upgrade on March 13, 2024. Transaction costs on major Layer 2 networks dropped sharply. A Uniswap swap on Arbitrum that previously cost roughly $0.37 fell to approximately $0.05, an 87 percent reduction. Fees on Base dropped by 80 to 98 percent. On Optimism, costs fell from around $0.32 to $0.07. On zkSync, fees dropped from approximately $0.08 to $0.02, a reduction of around 75 percent. As of 2025 and 2026, L2 networks collectively process more than 1.9 million daily transactions, with average fees around $0.08 and frequently under $0.01 for simpler transactions.

This matters acutely for users in emerging markets where small-value, high-frequency transactions are the dominant use case. India ranked first globally in Chainalysis's 2024 Geography of Crypto Report for the second consecutive year, with widespread use for investment and cross-border remittances tied to its large diaspora. Nigeria ranked second, where stablecoin adoption has accelerated alongside naira depreciation exceeding 40 percent in 2023. Kenya climbed from 32nd to 17th between 2023 and 2024, with crypto transaction volume doubling year-over-year to more than $51 billion. Pakistan also ranked inside the top 10 globally, driven by currency instability and a large unbanked population. For users in these markets, Ethereum mainnet fees averaging $3.78 and spiking to between $5 and $50 under congestion had been a real barrier. Layer 2 fees in the sub-dollar range, and often sub-cent, change the calculation entirely.

The Record and a Warning

The ceremony's final transcript, a 242-megabyte file with hash 8ed1c73857e77ae98ea23e36cdcf828ccbf32b423fddc7480de658f9d116c848, is archived on both GitHub and IPFS. More than 76,000 contributors claimed commemorative POAP NFTs.

One caution from the Foundation: contribution records from the ceremony should not be used as proof-of-unique-identity for airdrop targeting. The Foundation noted in its wrap-up post that anti-spam measures were imperfect and that many linked addresses showed signs of single-entity control. Projects in South Asian or African markets considering ceremony participation as a distribution mechanism should treat that list as unreliable for that purpose.

The KZG Ceremony belongs to a class of infrastructure events that rarely generate headlines but determine what becomes possible at the application layer. The fee cuts now benefiting users across Africa, South Asia, and elsewhere trace directly back to it.
