Polygon announces that the Giugliano hard fork will be activated on April 8, aiming to improve transaction confirmation speed and fee transparency, and support high-throughput payments and tokenized assets. The upgrade will embed fee parameters into the block header and roll out new RPC endpoints to optimize the developer experience. In addition, this upgrade is a major improvement for Polygon after experiencing multiple issues; despite market expectations, the POL token is still down by nearly 5%.

The Polygon mainnet will undergo a Giugliano hard fork upgrade on April 8, with improvements including faster block finality, integrating fee parameters into the block header, and new RPC endpoints that support fee queries. Node operators need to upgrade to the corresponding version to ensure the network functions normally.

The Ethereum Foundation released a quantum-safe roadmap, planning to introduce quantum-resistant mechanisms through a hard fork before 2029 to address the threat quantum computing poses to blockchain encryption. This upgrade includes optimizing public key support and enhancing layer 2 network security to ensure long-term security. The risk of quantum computing breaking existing encryption algorithms has already drawn attention from the Bitcoin ecosystem and institutions.

Ethereum co-founder Vitalik Buterin proposed Fast Confirmation Rules (FCR), aiming to reduce deposit confirmation time to approximately 13 seconds and optimize user experience. FCR provides early confirmation signals through validator attestations without requiring a hard fork. Despite concerns about centralization and honesty, it is still viewed as an important measure to improve network efficiency and is part of the Lean Ethereum roadmap.

Gate News: On March 19, Monad co-founder Keone Hon posted on Twitter stating that Monad mainnet will undergo a hard fork today at 22:30 Beijing time to upgrade to the MONAD_NINE version. This upgrade introduces three improvement proposals: MIP-3, MIP-4, and MIP-5. Before the hard fork, node operators need to upgrade to at least

Ethereum will introduce the "Fast Confirmation Rules" (FCR) on March 18, enhancing the efficiency of asset transfers from Layer 1 to Layer 2, with confirmation times reduced to approximately 13 seconds. This mechanism is implemented through "fast confirmation blocks," which enhance network throughput and user experience without compromising security, and is expected to drive the adoption of L2 solutions. No hard fork is required, simplifying the deployment process.

PANews March 6 News, according to The Block, the token issuance platform Doppler, which supports most new token launches on the Base chain, announced its expansion to the Solana network. Doppler stated that this migration is not simply a port or fork, but a native implementation tailored to Solana's unique architecture, constraints, programming model, and economic mechanisms. Doppler noted that it has been operating on multiple EVM chains and has integrated applications such as Zora and Bankr.

Optimism announces that support for op-geth and op-program will end on May 31, 2026, during which security patches will be released. New feature development will only be conducted on op-reth. Chain operators must complete the migration during the Karst hard fork to ensure network compatibility.

Ethereum's Vitalik introduced the EIP-8141 proposal on the X platform, aiming to address issues related to account abstraction (AA), with the core being "frame transactions." This mechanism supports various transaction scenarios, enhances security, and complements FOCIL to accelerate transaction execution. After years of research, the related technology is expected to be implemented through the Hegota fork within a year.

Former Mt. Gox CEO Karpelès proposes recovering the 79,956 BTC stolen in 2011, worth approximately $5.2 billion, through a Bitcoin hard fork. The plan allows funds in specific addresses to be managed under new rules to repay creditors, but it requires coordination across the entire network and carries a risk of division.
