Ethereum Fusaka Upgrade Activated on Sepolia Testnet
The Ethereum Fusaka upgrade activated on Sepolia testnet follows successful Holesky trials in October. The Ethereum Fusaka upgrade raises the block gas limit to 60 million and introduces Peer Data Availability Sampling (PeerDAS, EIP-7594), allowing validators to verify transaction data by sampling chunks from peers instead of downloading full datasets. These enhancements reduce storage requirements and improve data availability, boosting network scalability, throughput, and efficiency. Traders should monitor Sepolia’s performance as a gauge for the December mainnet rollout, which could influence ETH liquidity and market sentiment.
Bullish
The Fusaka upgrade’s increase in block gas limit and the introduction of PeerDAS directly address current scalability and data availability bottlenecks on Ethereum. In the short term, successful Sepolia testnet performance can boost trader confidence and ETH liquidity as market participants anticipate smoother transaction flow post-mainnet. Over the long term, improved throughput and reduced storage demands support a healthier, more efficient network, reinforcing positive sentiment around Ethereum’s upgrade roadmap and likely contributing to sustained price appreciation.
