The outgoing week proved eventful for the crypto market: the leading cryptocurrency showed volatility amid macroeconomic signals, while the industry saw breakthrough developments — from post-quantum transactions to decisions on Solana's monetary policy.
Bitcoin: Correction and Recovery
After attempts to hold above $81,000, bitcoin faced pressure. A speech by Fed Chair Kevin Warsh, who reaffirmed commitment to the 2% inflation target, triggered a dip below $76,000. The market reacted instantly: the probability of a rate hike at the September meeting rose from 35.4% to 57%. Nevertheless, by the end of the week, the asset recovered to $79,000, showing growth of more than 1.5% over the day and nearly 2% over the week.
Inflows into spot bitcoin ETFs slowed to $934.5 million versus $1.92 billion a week earlier, and Friday saw an outflow of $202 million, breaking a nine-day streak of net inflows. Ethereum funds, by contrast, strengthened inflows — to $824.4 million. Among altcoins, Solana (+12.4%) and HYPE (+4.3%) stood out, while XRP corrected by 7.5%.
First Step Toward Quantum Resilience for Bitcoin
The StarkWare team conducted the first-ever transaction on the bitcoin mainnet resistant to attacks from quantum computers. The experiment under the Quantum Safe Bitcoin (QSB) scheme did not require changes to consensus rules. The technology uses an additional layer of protection based on hash functions and a "signature-gridding" method. However, the method is still expensive and slow: preparing a single operation takes hours and costs hundreds of dollars. It is important to understand: this is an emergency mechanism for migrating individual coins, not full-scale protection for the entire network.
Solana Accelerates Disinflation
The Solana community approved proposal SGP-0002, doubling the pace of inflation reduction — from 15% to 30% per year. This will cut the time to reach the target of 1.5% from 5.7 to 2.8 years and reduce issuance by 18.9 million SOL over six years. Nominal staking yield will decline from 5.84% to 4.34% in the first year, which could affect the network's appeal to validators but will strengthen the asset's long-term economics.
Expert Opinion
StarkWare's quantum experiment is an important signal for the entire industry: preparation for the post-quantum era is no longer theoretical. As for Solana, accelerating disinflation is a bold move that the market received positively, but investors should closely monitor staking dynamics in the coming months.
