Gnosis Chain retires validator set, unlocking 350,000 GNO in rollup shift

Gnosis Chain is becoming the first instance of the Ethereum Economic Zone, trading its own validator set for settlement on Ethereum.

Gnosis Chain will retire its validator set and settle to Ethereum as a rollup, unlocking roughly 350,000 GNO, after GnosisDAO approved the shift.

The direction, approved in GIP-153 on GnosisDAO's governance forum, makes Gnosis Chain the inaugural instance of the Ethereum Economic Zone, a framework led by Gnosis and ZisK and funded by the Ethereum Foundation to give Ethereum and its rollups synchronous composability.

For GNO stakers, the sunset ends the treasury-funded staking subsidy that diluted non-stakers by about 2.3 percent a year, against sub-1 percent on Ethereum. The validator set had already contracted to roughly 52,000 active validators in July, down from about 76,000 a month earlier, with approximately 295,000 GNO staked, per GnosisDAO's community summary. The chain holds about $96.4 million in total value locked, according to DefiLlama.

The transition targets its first Ethereum Economic Zone block for December 2026 or January 2027, with bidirectional composability and real-time zero-knowledge proving expected during 2027. GNO's replacement economic role — fee sharing or buybacks — remains undecided, deferred to a later GIP after prover economics can be observed in production.

Validator Security Gives Way to Ethereum Settlement

Gnosis Chain began as xDai, a stablecoin-denominated Ethereum sidechain that GnosisDAO absorbed in a November 2021 merger, and switched to proof-of-stake in December 2022 in an upgrade modeled on Ethereum's Merge, with a deposit of one GNO per validator against Ethereum's 32 ETH.

The low threshold produced one of the largest validator sets in crypto, above 100,000 at the time of the merge, but not the fee revenue to pay for it. GIP-153 says fees cover "only a small fraction of even the minimal cost of security," leaving the DAO treasury to fund the rest through GNO issuance. GnosisDAO also cut Gnosis Ltd's annual funding to $15 million from a $30 million request in GIP-154, and in May approved a one-time, pro-rata treasury redemption in GIP-151 after tokenholders spent months arguing GNO traded below the DAO's net asset value.

GIP-153 says Ethereum validators will replace Gnosis Chain's validator set as the source of settlement security. Existing bridge validators are intended to move into a new role operating the instance's proof systems. The proposal explicitly describes becoming less decentralized as a deliberate choice: a misbehaving composer could delay or exclude transactions, though it could not forge state or reverse finalized history. A forced-inclusion route through Ethereum is listed as an option to evaluate later, not a launch feature.

Full Composability Is a Later Step

Gnosis Chain said the transition would deliver "synchronous composability with mainnet," something it said no existing Layer 2 offers. GIP-153 defines the initial capability more narrowly: a contract on Gnosis could call an Ethereum contract and use the result in the same atomic transaction, with the entire operation succeeding or reverting together.

At launch, composability would only run from Gnosis to Ethereum. An intents-based bridge is intended to cover the period before bidirectional and cross-instance calls become available. The initial version would also use an interim proving setup, likely based on trusted execution environments, before moving to real-time zero-knowledge proving.

For users and developers, xDAI would remain the gas token, while addresses, balances and contract state would continue without migration to a new chain. The network would produce blocks every two seconds and prove its state every Ethereum block. Gnosis Ltd will initially operate a centralized composer that orders transactions, builds blocks and submits them for proving and settlement.

The vote approved a strategic direction rather than a final technical design and requested no funding. At the time of writing, GIP-153 sat around 98 percent in favor, with quorum at 9 percent of the threshold, and the vote was open through August 19.

The transition could set a precedent for other Layer 1 chains weighing similar moves, as Ethereum's rollup ecosystem — Arbitrum, Optimism and Base among them — competes for liquidity and developer mindshare. If Gnosis delivers synchronous composability, it would offer something no existing Layer 2 provides, potentially drawing DeFi activity that currently fragments across bridges.
