Tezos launches post-quantum previewnet ahead of quantum threat
Tezos (XTZ)

Bitcoinethereumnews.com reports that Tezos has unveiled a previewnet for its post-quantum protocol on September 2, 2026. This move addresses the growing risk quantum computers pose to traditional cryptographic systems, a concern heightened by Google’s March 2026 research showing reduced resources needed to break elliptic-curve cryptography. The new network builds on the June 2026 Ushuaia protocol amendment, which introduced testnet support for the NIST-standardized CRYSTALS-Dilithium algorithm.
Core developers implemented a STARK-based solution from LeanEthereum to aggregate hash-based signatures for consensus operations. Additionally, the Data Availability Layer now uses ZODA, a protocol offering near-zero communication overhead. These upgrades aim to secure user keys, consensus, and randomness generation against future quantum attacks.
Tezos is asking bakers and community members to test the experimental network throughout September. The native token XTZ trades at $0.213958 with a market cap of $235.9 million. The initiative aligns with broader efforts like TzEL for private, post-quantum payments. This development positions Tezos as a proactive player in securing blockchain infrastructure against advancing quantum technology.
How the market reacted
Whalio's own Binance spot order flow for XTZ, measured when this story was written up on 2 September 2026. Not the outlet's figures.
XTZ is trading at $0.2145 on Binance spot, showing a buy ratio of 46.1% over the last hour and 45.6% over four hours. These short-term figures are below the 51.5% buy ratio recorded over the past 24 hours, indicating that immediate buying pressure is fading. Volume delta reflects this shift, dropping by $1,018 in the last hour and $3,050 over four hours, compared to a net positive of $8,967 over the full day. The cumulative volume delta (CVD) for the 24-hour period closed at -$49,726, suggesting that sellers have dominated the recent flow. Only six out of the last 24 hours saw net buying, with spot volume totaling $313,365 across 5,437 trades. This data suggests that while the daily average favored buyers, the most recent activity has tilted toward selling.
The latest daily buy ratio of 44.0% sits at the 8th percentile of the last 322 days, against a median of 49.6% - among the weakest buying days it has had.
Was that an ordinary day?
The same Binance spot measurements for XTZ, averaged over the days leading up to the story.
Over the preceding week, XTZ experienced a 4.0% price decline, with volume trading at 0.81 times its average level. The 24-hour buy ratio of 51.5% is slightly higher than the 7-day average of 50.9%, marking a marginal increase of 0.6 percentage points. However, the current day’s volume is below average, indicating reduced participation compared to typical trading days. Net buying occurred on only four of the past seven days, contrasting with the six days of net buying in the last 24 hours. The total volume delta for the week stands at +$72,905, showing that weekly buying has outweighed selling despite the price drop. This suggests that while the asset is underperforming on price, it has seen more days of accumulation than distribution over the longer timeframe.
