Grayscale: Quantum computing or early breakthroughs are accelerating—preparing for post-quantum encryption is urgent.

Grayscale research director said that technical breakthroughs in quantum computing could introduce uncertainty, so public blockchains need to accelerate the deployment of post-quantum cryptography. A Google paper highlights the time sensitivity of quantum risk, specifically noting that if quantum computers reach a certain number of logical qubits, they will threaten existing encryption systems. Solana and the XRP Ledger have already begun experimental deployments of post-quantum cryptography technology. While Bitcoin has lower technical risk, challenges still exist at the governance level.

MegaETH releases an investor memo, and in April it will roll out new products and TGE milestones

High-performance Layer 2 protocol MegaETH recently released an investor memo, outlining on-chain progress and updates to the Mafia ecosystem, and clearly set out a KPI-based token generation event plan. GMX, through its deployment on MegaETH, delivers real-time trading experiences with performance close to that of a centralized exchange, further narrowing the performance gap between DeFi and CEX. The team commits to driving stablecoin adoption and the growth of functional applications through accountability mechanisms, and expects to achieve major progress in April.

Polygon Giugliano upgrade takes effect on April 8, nodes act immediately

Polygon Foundation announced that the Giugliano hard fork will be launched on April 8, bringing improvements such as faster transaction confirmations, greater fee transparency, and new RPC interfaces. Node operators must upgrade to the corresponding version before the specified block height to avoid losing synchronized connections with the mainnet.

Solana ecosystem DEX aggregator Titan launches on-chain router DART

Solana ecosystem DEX aggregator Titan launched the on-chain router DART on April 7. By dynamically allocating trading volume to the best liquidity sources in real time, it reduces trading costs; tests show costs are below 0.02%. In the future, it will expand to more trading pairs, and the DART API will enter the beta testing phase.

HypurrFi announces that the blockchain hash has surpassed a new milestone, and the same day it also faced a domain hijacking incident

HypurrFi announced that its independently developed Hyperliquid client has successfully achieved block-hash consistency, enabling developers to independently verify the on-chain state and improving decentralization. On the same day, it discovered a domain-hijacking incident; although it did not affect users’ funds, it still urged everyone to stop interacting with suspicious domains immediately and to obtain updates through official channels. AI contributed 99.9% to this technical development.

Chaos Labs exits Aave, saying there is a legal gap in DeFi risk management

Risk management firm Chaos Labs announced it is ending its three-year partnership with DeFi lending protocol Aave, citing a fundamental disagreement between the two parties on approaches to risk management. This exit has exposed the legal gray area in the DeFi ecosystem where regulatory safeguards are lacking—especially after a recent oracle incident that led to an erroneous liquidation of about $27 million. The separation between Chaos Labs and Aave leaves Aave facing a governance vacuum during a critical period for the V4 upgrade, further fueling concerns about accountability for decentralized risk systems.
