The Quantum-Safe Bitcoin (QSB) proposal put forward by StarkWare researcher Avihu Levy uses existing Bitcoin scripts to provide post-quantum security, avoiding a soft fork. QSB uses a Binohash-based construction and a “hash-to-signature” puzzle to defend against quantum computers’ attacks on elliptic curve cryptography. The scheme relies on RIPEMD-160’s preimage resistance, effectively strengthening the security of Bitcoin transactions.

StarkWare researchers proposed a quantum-safe Bitcoin scheme called QSB, aiming to replace the elliptic curve mechanism with hash assumptions to counter the threats posed by Shor’s algorithm. The scheme can run within existing scripts, requires no consensus changes, but does require submitting a transaction to a specific service.

Gate News message. April 7, Tether CEO Paolo Ardoino said the team is developing a decentralized search engine called hypersearch. The product is built on a distributed hash table (DHT, a decentralized data storage technology) architecture.

Gate News reported that on March 28, Nasdaq-listed Bitcoin mining company LM Funding America disclosed its financial performance data. The company mined 22 BTC in the fourth quarter of 2025 and held 354.7 Bitcoins as of February 28, 2026, including 174 Bitcoins held in the Galaxy Digital digital asset receivables account. Additionally, the company's total mining hash rate reached approximately 782 PH/s.

CoinShares reports that Bitcoin miners are under profit and loss pressure, with mining costs rising to approximately $79,995 in 2025, while hash rate prices continue to decline. Mining companies are accelerating their shift toward AI, and it is expected that by the end of the year, revenue from AI will account for 70%. If Bitcoin's price rebounds to $100,000, hash rate prices are likely to recover.

CoinShares' Bitcoin mining report indicates that global Bitcoin miners are under profit pressure, with 15%-20% of mining farms operating at a loss, and the hash price reaching a five-year low. Older mining equipment and miners with high electricity costs are most affected. Recent difficulty reductions have eased short-term pressure, but a prolonged downturn could force some farms to shut down, impacting network stability. Miners need to assess costs and efficiency to ensure sustainable operations.

Bitcoin price continues to remain below $72,000, with weakening market demand as investors begin to sell off positions, limiting short-term upside potential. On-chain activity and mining hash rate are declining, miner profitability is weakening, and market concerns about miner sell-offs are intensifying.

Bitcoin miners currently have an average production cost of $88,000, with market prices around $69,200, resulting in losses of 21%. Mining difficulty has decreased by 7.76%, with hash price approaching the break-even line. Most mining enterprises are shifting toward AI business, and increased miner Bitcoin sales are adding selling pressure to the market. The next difficulty adjustment is expected in early April, and if conditions persist, further downward adjustments may occur.

Provenance Blockchain's HASH token rose 17.5% in 24 hours to reach a market cap of $807 million, but the increase was supported by low trading volume of only $112,477, raising concerns about liquidity and price stability.

Gate News reports that on March 19, the HASH token of Provenance Blockchain increased by 23.8% within 24 hours. Data shows that the trading volume of this token during the same period was $114,406, which is relatively small and may indicate a tight supply situation.
