Layer-1 blockchain Qubic has restarted the network and initiated the fund recovery process. Previously, attackers exploited a wallet seed vulnerability to transfer approximately 1.4 million USD worth of QU tokens from 1,404 accounts. The network validator Computors has approved the recovery plan, and affected users can submit claims, with a deadline of May 1, 2027.The Qubic block explorer shows that the network resumed processing ticks on October 19 at 20:00, with progress exceeding the previously paused 85,371,949. The vulnerability affects wallet seeds generated by certain Apple devices and browsers. Qubic recommends using version 4.26.4 or above to create new wallets and to transfer funds as soon as possible.

Whale Alert posted on the X platform that USDC Treasury minted two transactions of 250 million USDC each on the Solana network at 03:47 and 03:49 Beijing time, totaling 500 million USDC, worth approximately 500 million USD.Data from the Solana block explorer shows that both transactions were executed by the USDC minting authority address.

A network startup company called Optimum, led by Professor Muriel Médard from the Massachusetts Institute of Technology, announced that its block propagation software mump2p has officially launched on the Ethereum mainnet. The Ethereum liquid staking protocol ether.fi has made mump2p a mandatory requirement for all 12 of its node operators, whereas previously the software was optional for its operators.Optimum stated that there are currently 16 node operators running mump2p in production environments, collectively managing approximately 22,000 validator keys and over 1.4 million staked ETH, accounting for more than 3% of the total staked amount on Ethereum. Partners include Blockdaemon, Everstake, P2P.org, Stakefish, and Bitcoin Suisse. The software operates in a sidecar gateway manner, not replacing Ethereum's default GossipSub, but rather overlaying it on top of libp2p and utilizing random linear network coding technology. Optimum claims that the block arrival speed is 2.42 times faster than GossipSub, with an approximately 7.88 times reduction in arrival time variance.Rok Kopp, co-founder and Chief Growth Officer of ether.fi, stated that they will not require the entire validator set to adopt a new infrastructure unless they are confident that it can enhance the overall level of stakers and the network. Médard mentioned that traditional financial institutions invest billions of dollars to shorten execution times to the millisecond level because speed is money. Optimum launched its private testnet in June 2025, having previously completed a $11 million seed round financing led by 1kx, and plans to expand the protocol to other high-throughput blockchains after Ethereum.

According to The Defiant, the cryptocurrency exchange Blockchain.com has announced the launch of options trading services, initially supporting seven types of crypto assets.

On-chain data analyst XWIN cited CryptoQuant data indicating that Bitcoin's current on-chain data is showing a significant divergence between whale behavior and the spot market. Although large holders have begun to accumulate again, demand in the spot market remains weak, and the market is transitioning from "seller exhaustion" to a potential bottom. XWIN stated that on-chain data shows positive accumulation signals. Holders of 1,000 to 10,000 Bitcoins have significantly reversed their 60-day net accumulation from negative 62,600 to positive 5,230, indicating that major whales are shifting from a distribution model back to accumulation.At the same time, the USDT reserves on the Binance trading platform have surged from about 790 million USD to 1.76 billion USD, suggesting that potential buying power in the market is increasing. However, spot buying in the U.S. has not kept pace. The Coinbase premium index is currently around -0.1416%, and weekly trading platform flow has turned into a net inflow of 8,428 BTC. Additionally, the short-term holder spent output profit ratio (STH-SOPR) hovers around 0.9982, indicating that short-term holders are still experiencing slight losses near the breakeven point and are choosing to sell.Analysts believe that while the underlying structure is improving, stronger spot demand is still urgently needed to spark a sustainable rebound. They suggest that investors focus on three key signals in the future: the trend of the Coinbase premium index, changes in exchange net flow, and whether the STH-SOPR can successfully rise above the 1 mark.

The American Blockchain Association stated that it has submitted comments on the proposed implementation rules for Section 3 of the GENIUS Act by the U.S. Department of the Treasury. The association recommends clarifying the scope of "digital asset service providers" to exclude self-custody software, validators, and businesses that only trade their own assets; regarding criminal liability for participating in the illegal issuance of stablecoins, it should be based on actual knowledge and substantial assistance coordinated with the issuer.The association also suggested that trading platforms could determine the compliance of foreign stablecoins based on the official issuer list and trading bans, and adjust the criteria for determining user locations in unlicensed agreements.

According to The Block, Nasdaq-listed company OpenWorld (stock ticker: OPNW) has signed a merger agreement to acquire the AI agency Blocksight.Blocksight's AI agency is expected to serve as the operational layer for OpenWorld's recently announced tokenized financing plan, responsible for transaction structure design, asset verification, and daily reporting, with the total financing plan amount exceeding 1.1 billion dollars.

According to Bloomberg, Hyperliquid Labs co-founder Jeff Yan is seeking the United States to establish rules that can protect its blockchain. He believes that Hyperliquid's regulatory responsibilities should fall on the financial institutions operating markets based on that blockchain, namely the application layer, rather than the blockchain network itself. This regulatory division allows Hyperliquid to enter Wall Street without bearing the full compliance burden of traditional exchanges.Jeff Yan also stated that Hyperliquid is currently not open to U.S. customers, and Hyperliquid prefers to be the underlying trading technology used by traditional financial institutions, rather than replacing existing market participants, positioning itself similarly to how Amazon Web Services (AWS) provides computing infrastructure for businesses.

Cryptocurrency analyst Darkfost stated that after Bitcoin encountered resistance around $87,000, the MVRV indicator has fallen below the historical 30th percentile (25.7%), indicating that the market has re-entered a transitional phase after experiencing a capitulation-style sell-off.Darkfost further pointed out that this indicator does not simply measure the ratio of Bitcoin's market value to its realized value, but rather compares the current MVRV level against the historical context of its evolution. The historical time proportion corresponding to the current valuation level is only about 25%, which still aligns with the characteristics of the market accumulation range. However, Bitcoin has moved away from the extremely undervalued range, which has historically coincided with market bottoms.

According to Decrypt, nine blockchain organizations including Quantus, Postquant Labs, Midnight Foundation, Keystone, Abelian, and Hacken have jointly established the Quantum Alliance, aiming to develop "quantum-ready" open standards and establish a unified approach to test the quantum resistance of blockchain networks, wallets, and infrastructure.The Quantum Alliance stated that currently, approximately 6.04 million BTC, accounting for about 30% of the Bitcoin supply, are at potential risk of quantum attacks due to the exposure of elliptic curve signature public keys. The organization will focus on promoting blockchain migration, post-quantum zero-knowledge systems, wallet security, and cross-chain compatibility, citing recent predictions that practical quantum attack windows may appear as early as around 2028.

The Brazilian Securities Commission (CVM) issued Resolution No. 249, launching a tokenized securities experimental project to test simulated stock trading and securities issuance, operation, and management on a blockchain network. The project will take place in a controlled environment, using stocks and funds that are specially created simulated assets, without involving real financial risks.The project will compare the advantages and disadvantages of public chains versus private chains for securities business and assess risks such as network security, smart contracts, interoperability, and network resilience. The blockchain networks participating in the pilot must encode market rules into smart contracts, maintain privacy in securities operations, and be subject to audits by regulatory agencies. Brazil's largest stock exchange, B3, is building a tokenization platform, which is scheduled to launch in 2027 and will use a self-developed stablecoin. Initially, it will not provide round-the-clock trading and will integrate liquidity pools of digital assets and traditional markets.
