Ethereum has just reached a spectacular milestone in terms of scalability. On November 4, 2025, the network recorded a record throughput of 3,453 transactions per second, shattering its usual performance. Vitalik Buterin, co-founder of the blockchain, was quick to welcome this major breakthrough. But does this technical feat finally herald the end of the congestion problems which have long handicapped the network?
In brief
- Ethereum reached an all-time high of 3,453 transactions per second on November 4, 2025 at 2:37 p.m. UTC.
- Vitalik Buterin immediately reacted on social networks to congratulate this breakthrough in scalability.
- Layer 2 solutions like Arbitrum, Optimism and Base play a key role in this rise.
- PeerDAS technology, identified by Buterin as “crucial,” is expected to further amplify these capabilities in the coming months.
Ethereum breaks all-time speed record with 3,453 TPS
On November 4, 2025 at 2:37 p.m. UTC, Ethereum shattered its speed ceiling by reaching 3,453 transactions per second.
A figure that makes you dizzy when you know that layer 1 of Ethereum usually processes between 15 and 30 TPS under normal conditions. Vitalik Buterin was quick to react, publishing a terse but eloquent message: “Ethereum is scaling up.”
This performance is not the result of chance. It is the result of years of effort to solve Ethereum's main Achilles heel: network congestion during periods of high demand.
Layer 2 solutions, including Arbitrum, Optimism, Base and zkSync, now play a central role in this rise. By offloading a massive portion of transactions off the main blockchain, these protocols allow the combined Ethereum ecosystem to process thousands of operations simultaneously.
This record comes at a strategic time. Financial institutions, businesses and even some governments are closely observing the technical capabilities of blockchains before considering their mass adoption. Ethereum thus demonstrates that it can compete with traditional payment systems in terms of speed, while preserving the benefits of decentralization.
PeerDAS, the secret weapon to go even further
Buterin does not intend to stop there. The Ethereum co-founder recently identified PeerDAS (Peer Data Availability Sampling) as “the missing link” to propel the network to new heights.
This technology, integrated into the Fusaka upgrade scheduled for December 2025, revolutionizes the way nodes manage data.
Concretely, PeerDAS allows validators to verify the existence of a block without having to download all the information. They use data samples that they reconstruct using erasure coding. Result: the storage load decreases drastically for each node, which increases the overall capacity of the network without sacrificing decentralization.
Buterin also praised zkSync Atlas as “underrated and valuable,” while reaffirming that “incorruptibility” remains the fundamental property of a robust blockchain.
These statements demonstrate a coherent vision: to build a system capable of absorbing exponential demand while remaining faithful to the principles of neutrality and resilience that founded Ethereum.
A global ambition that is finally coming to fruition
This GST record is not just a number to celebrate. It represents a concrete validation of Ethereum's strategy against its competitors.
While other blockchains focus on raw speed to the detriment of decentralization, Ethereum proves that it is possible to combine performance and principles.
The network's ambitious roadmap, with the Pectra, Fusaka and Glamsterdam upgrades, outlines an infrastructure capable of supporting the global finance of tomorrow.
Banks, investment funds and governments considering asset tokenization or stablecoin issuance now have a credible technical platform. Ethereum no longer just promises: it demonstrates.
