Ethereum has officially rolled out its Fusaka upgrade, a major step aimed at boosting how many transactions the network can handle—without sacrificing security or decentralization. The update is now live, and according to Ethereum’s documentation, it’s built to help the blockchain scale while staying true to its core principles.
Even Vitalik Buterin took a moment to celebrate the moment, posting on X:
“Big congrats to the Ethereum researchers and core devs who worked hard for years to make this happen.”
What the Fusaka upgrade does
The heart of the upgrade is EIP-7594, also known as PeerDAS (Peer Data Availability Sampling). This new system lets Ethereum nodes verify that block data is complete without downloading every piece of it. That means less strain on nodes, faster verification, and better network efficiency overall.
This improvement is especially important as Ethereum continues to support the growing DeFi world. The network currently hosts over $73 billion in decentralized finance apps and processes between 1.3 million and 1.8 million transactions every day, according to Etherscan.
A big milestone on Ethereum’s scaling roadmap
Fusaka fits into Ethereum’s larger plan to scale through sharding, a method where the network is split into smaller parts so it can process more transactions at once. Developers say this upgrade is another step toward that long-term goal—boosting network capacity while still keeping Ethereum secure and decentralized.
Vitalik highlighted how long this moment has been in the making, saying:
“Sharding has been a dream for Ethereum since 2015… and data availability sampling since 2017. And now we have it.”
Market reaction
Ethereum didn’t waste time reacting. After the upgrade went live, the price moved above $3,000, climbing about 5% to trade near $3,162 at last check.
