Poland fails to override Nawrocki's veto on crypto regulation, delaying MiCA alignment by the July 1 deadline as firms relocate to Latvia, Czech Republic, Lithuania, and Malta amid regulatory uncertainty. Poland's parliament again blocks the crypto regulation by Nawrocki's veto, leaving MiCA alignment to a future date and spurring domestic firms to move operations to other EU member states. The dispute centers on concerns about overregulation and broad KNF powers, intensifying political tensions and accelerating crypto outflows before MiCA's transition ends.

On April 3, a miner who mined solo through CKPool successfully mined block #943,411, earning about 3.139 BTC in rewards, worth about $210k. Solo mining is still a low-probability event; in the past 12 months, only 20 blocks were mined. Mining competition has intensified, and network difficulty has shown fluctuations.

Ethereum Foundation researcher Jihoon Song presented FOCIL’s progress at the EthCC conference. The project aims to reduce Ethereum’s centralization risk by using a decentralized committee of validators. FOCIL improves blocks’ resistance to censorship by randomly selecting validators and encoding rules, lowers attack risk, and supports account abstraction and privacy protocols. This mechanism has been confirmed as a core feature of Ethereum’s future upgrades.

An Ethereum Foundation researcher presented the zkAttester client solution at the EthCC conference, addressing the computational burden of node re-execution, allowing validators to verify zero-knowledge proofs directly, lowering CPU performance requirements, shortening the time for new node synchronization, and helping enable Ethereum light verification and scaling.

Ethereum block builder Eureka Labs completes $6.7 million seed round funding. The funds will be used to develop its "programmable blocks" technology, aimed at enhancing security and flexibility in the block construction process.

Ethereum block builder Eureka Labs completes $6.7 million Series Seed funding round led by Spark Capital and Collider Ventures. The company introduced the "programmable blocks" concept and plans to expand its technical capabilities and drive its applications in the Ethereum ecosystem.

BTQ Technologies announced on March 19 that it successfully implemented BIP 360 on its Bitcoin Quantum Testnet v0.3.0, launching the Pay-to-Merkle-Root transaction format to address quantum computing threats. The testnet has connected over 50 miners, processed over 100,000 blocks, and supports P2MR transaction functionality.

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.

Gate News, on March 18, Starknet mainnet will begin a planned upgrade starting at 17:10 (UTC+8) today, with an estimated downtime of approximately 12 minutes. Starknet stated that this upgrade is part of its move toward further decentralization, which will transfer the block hash calculation of Starknet blocks to decentralized Apollo nodes.
