The Fusaka update, recently activated on the Ethereum mainnet, represents a significant milestone in the evolution of this blockchain. Considered one of the most important hard forks in recent times, Fusaka was designed to directly tackle the persistent challenges of scalability and efficiency that have limited the network's potential. The central objective is clear: to drastically reduce costs for users and developers while preparing the infrastructure for a future of mass adoption.
To understand the magnitude of this update, it is essential to analyze its five fundamental pillars:
1. Massive Increase of Gas Limit
The most immediate and impactful change is the substantial increase of the gas limit per block, which rises from 36 million to 60 million units. This change is not merely technical; it translates into a direct increase in the network's capacity to process transactions and complex smart contracts. On the base layer (Layer 1), this allows Ethereum to process between 40 to 60 transactions per second (TPS). However, the real impact is felt in Layer 2 solutions, which can now achieve up to 100,000 TPS, putting Ethereum in direct competition with other high-speed blockchains like Solana.
2. Innovation with PeerDAS (EIP-7594)
The introduction of Peer-to-Peer Data Availability Sampling (PeerDAS) is perhaps the most sophisticated technical innovation of Fusaka. This technology allows network nodes to validate data availability without the need to download all the information contained in a block. By reducing the computational load required to operate a node, Ethereum promotes greater decentralization, making it easier for individuals and small entities to participate in network validation. For Layer 2 solutions, such as Arbitrum or Optimism, PeerDAS is vital, optimizing the organization and distribution of transaction data.
3. Optimization in Blob Handling
The update significantly expands the storage capacity for blobs (Binary Large Objects). These data objects are fundamental for interoperability between the main layer and Layer 2 networks. With more efficient handling and greater capacity for blobs, Layer 2 networks can publish large volumes of data to Ethereum much faster and more economically. The practical result is a reduction in transaction fees for the end user and increased speed in decentralized applications (dApps).
4. Strengthening Security and the EVM
Fusaka does not only focus on speed; security remains a priority. Through proposals like EIP-7825, the network strengthens its defenses against denial-of-service (DoS) attacks. Additionally, improvements have been implemented in the Ethereum Virtual Machine (EVM) to accelerate processing and support modern cryptographic signatures, such as the R1 signature used in passkeys. This ensures that the performance increase does not compromise the robustness and reliability that characterize Ethereum.
5. Preparation for the Future: Towards "Glamsterdam"
Finally, it is crucial to understand that Fusaka is not an isolated event, but rather part of a long-term strategic roadmap. This update lays the groundwork for the transition to a "Stateless Ethereum" and for the future implementation of the RISC-V virtual machine, expected to occur between 2026 and 2028. Fusaka specifically prepares the ground for the next major update, called "Glamsterdam," which will continue to focus on speed, resistance to censorship, and processing capacity.
In summary, the Fusaka update redefines the Ethereum ecosystem, making it faster, cheaper, and more secure, consolidating its position as the leading platform for smart contracts, decentralized finance (DeFi), and much more.
