QuickNode Opens Ethereum Fast Confirmation Beta
Developers can now access faster Ethereum block confirmations on mainnet endpoints through a beta of the Fast Confirmation Rule.
Updated on Nov. 5, 2026 in Quantum Computing
QuickNode opened a beta of Ethereum's Fast Confirmation Rule on mainnet RPC endpoints on November 4. The beta gives developers access to faster block confirmations through the safe tag, and Gnosis uses the rule for transfers from Ethereum to Gnosis Chain.
Why it matters
Ethereum finality takes at least about 13 minutes, so a faster signal of block confirmation could shorten waits for applications that depend on settlement. The rule relies on validator attestations rather than waiting for full finality.
The rule depends on no more than 25% of validators being Byzantine and on honest validators' attestations arriving by the end of a slot. A block that received fast confirmation can be reorganized if either condition fails, and Ethereum slots last 12 seconds.
The players
QuickNode
QuickNode is a blockchain infrastructure provider that offers RPC endpoints used by developers to query Ethereum and other networks.
Gnosis
Gnosis is a blockchain ecosystem that operates Gnosis Chain and uses the Fast Confirmation Rule for bridge transfers from Ethereum.
The details
Developers enable the rule on a mainnet endpoint and continue querying the safe tag to receive fast-confirmed blocks. Bridge validators on Gnosis run their own Ethereum nodes to determine fast confirmation for transfers.
Timeline

The Tech Race
The Fast Confirmation Rule is an Ethereum-native mechanism that layers faster signals on top of the existing finality process rather than replacing it. Its move into RPC infrastructure places it among the faster-settlement features competing blockchain ecosystems are racing to offer.
Developers building on Ethereum mainnet endpoints can now query faster-confirmed blocks through the safe tag, which may shorten wait times for transaction-dependent applications. Users bridging assets from Ethereum to Gnosis Chain may see faster transfer confirmation as a result.
The takeaway
Faster block confirmation depends on validator honesty and timely attestations, so developers should treat fast-confirmed blocks as provisional until full finality. Reviewing the rule's assumptions before building settlement logic on it can prevent reorganization-related errors.
