Hard Fork

The Ethereum Fusaka hard fork is set for December 3, 2025, aiming to scale the Ethereum blockchain with incremental blob capacity upgrades following the main activation. Testing will occur in October 2025 across multiple public testnets.

Anatoly Yakovenko, co-founder of Solana, warns at All-In Summit 2025 that Bitcoin's current cryptography may be vulnerable to quantum computers by 2030, urging a hard fork to quantum-resistant signatures. However, experts like Adam Back and Peter Todd remain skeptical about the immediacy of this risk.

The Ethereum Fusaka Hard Fork, launching on December 3, 2025, introduces major improvements including 12 new EIPs, enhanced blob capacity, and heightened security to boost network scalability and reduce costs. This upgrade follows the Pectra update and includes an extensive public testing phase and a $2 million code audit program by the Ethereum Foundation.

Ethereum's upcoming Fusaka hard fork in November focuses on improving network performance and security, with no new user features introduced. Explore how this upgrade impacts the Ethereum ecosystem and discover convenient ways to invest in crypto through Bitlet.app's installment service.
