Ethereum’s price rose sharply above $3,000 on Wednesday, posting a 10% increase within 24 hours. The rally came as the long-awaited Fusaka upgrade was officially launched on the Ethereum mainnet. Market momentum grew stronger amid a wider crypto recovery, with traders reacting positively to Ethereum’s improved scaling roadmap.

Fusaka Upgrade Officially Activated on Mainnet

Ethereum’s Fusaka upgrade was activated today at 21:49 UTC. It combines two protocol advancements: Osaka on the execution layer and Fulu on the consensus layer. This upgrade is Ethereum’s second network update in 2025 after the earlier Pectra release.

The upgrade introduces several technical changes aimed at improving network performance. The core update is PeerDAS, a data availability sampling method. It improves how Layer 2 data (blobs) are stored and verified on Ethereum. Instead of each node storing all blob data, they now store only one-eighth of it, making the network more efficient.

PeerDAS enables theoretical data scaling up to 8 times while reducing storage and bandwidth stress on full nodes. The approach ensures that data availability remains verifiable even when each node holds only a portion of the data.

Scaling Layer 2 with Cost Control Measures

The Fusaka upgrade also brings mechanisms to manage blob data growth and costs. One is the “blob-parameter-only” fork, which allows Ethereum clients to increase blob counts without waiting for a full network upgrade. This supports more frequent, smaller adjustments to meet Layer 2 demands.

Before Fusaka, the target blob count was six, raised from three in the previous Dencun upgrade. After Fusaka, clients can increase this further, such as to nine or twelve, without requiring full coordination among all nodes.

Additionally, a new cost control system ties blob base-fees to execution gas costs. This prevents blob fees from dropping to nearly zero during low activity, which can distort network pricing. EIP-7918 ensures that blob fee adjustments remain sensitive to both compute load and block congestion.

Additional Protocol Limits for Safety and Performance

To support future scaling plans, Fusaka introduces several security-focused limits. One of these is a gas cap of 16,777,216 per transaction, set by EIP-7825. It ensures that no single transaction can consume excessive resources, helping stabilize network performance.

Another change limits the size of inputs for the MODEXP precompile, a function used for complex math operations in cryptography. EIP-7823 now rejects any input over 8192 bits. This change prevents edge cases from overloading nodes and helps maintain a balanced execution environment.

There is also an update to MODEXP’s gas pricing via EIP-7883. The new model raises the minimum gas cost and scales more sharply for large inputs. This better aligns fees with actual processing times, making it safer to raise Ethereum’s block gas limit in the future.

Crypto Market Rallies as Ethereum Leads Gains

The Fusaka upgrade coincided with a broader rally in the crypto market. Ethereum’s move past $3,000 helped boost trader sentiment after several days of price consolidation.

Bitcoin traded above $93,000, adding strength to the bullish trend. Other major altcoins also posted gains: Solana rose 12%, XRP climbed 10%, and BNB gained 8%. DOGE and ADA matched Solana’s performance, with 12% increases.

The upgrade sparked renewed interest in Ethereum’s long-term potential. According to a crypto analyst, ETH is showing signs of a wedge breakout. He noted that price action has tightened and suggested a possible move toward the $5,000 level. “ETH is nearing the wedge apex,” the analyst said. “If it breaks out, $5K is a potential target.”
