StarkWare Enables First Quantum-Safe Bitcoin Transaction on Mainnet
Bitcoin (BTC)
Cryptobriefing.com reports that StarkWare successfully mined the first quantum-safe Bitcoin transaction on mainnet on August 26, 2026. The transaction, ID 305a24ffea912b9cf428f29ebf952321c96dab5bab284fc0d0801562f5abab07, utilizes the Quantum Safe Bitcoin construction developed by Avihu Levy. This method replaces ellipt-curve signatures with Lamport-style hash-based cryptography to protect against quantum computing threats without altering consensus rules. The implementation fits within existing Script limits, requiring no soft fork or protocol-level negotiations. However, the process demands significant off-chain computation, costing between $75 and $150 per transaction. These nonstandard transactions bypass typical mempool relays by going directly through MARA Slipstream. StarkWare CEO Eli Ben-Sasson described the initiative as a passion project demonstrating immediate asset protection for high-value holders.
What Whalio's data showed
Binance spot order flow for BTC, measured when this story was published on 27 August 2026.
Bitcoin trades at $79,023.75 with a 24-hour spot volume of $1,148,236,056. The 1-hour buy ratio of 54.0% and 4-hour ratio of 52.2% indicate stronger short-term buying interest compared to the 24-hour ratio of 49.9%. This shift suggests that buying pressure is building in the immediate term despite the daily average leaning slightly toward selling. Volume delta supports this trend, showing positive inflows of +$4,359,314 over the last hour and +$8,330,477 over the last four hours. In contrast, the 24-hour volume delta is negative at -$903,088, reflecting earlier selling pressure that has recently reversed. The cumulative volume delta for the 24-hour period stands at -$43,235,796, indicating that net selling dominated the full day before the recent intraday surge in buys.
