BlockBeats News, January 12 — According to Coindesk, the quantum-resistant cryptography professional organization BTQ Technologies (BTQ) recently announced a permissionless fork testnet called “Bitcoin Quantum” (比特币量子) to protect the Bitcoin blockchain. The network claims to be capable of addressing quantum challenges.
BTQ’s partnership lead Chris Tam stated that Bitcoin Quantum is an open, operational network where miners, developers, researchers, and users can conduct stress tests against quantum transactions and reveal practical trade-offs before discussions on mainnet upgrades become urgent. The system includes a block explorer and mining pools, providing immediate accessibility.
Tam explained that in August 2024, the so-called “Dilithium” quantum-resistant algorithm (officially known as the lattice-based digital signature algorithm ML-DSA) was standardized in the United States. This algorithm is the technology used by the Bitcoin Quantum network. Such algorithms have not yet been widely adopted in fast-evolving fields like cryptocurrencies, mainly due to high operational costs. Compared to the digital signatures used when sending information to the blockchain or even sending WhatsApp messages, quantum-resistant algorithms increase data size by at least 200 times. Therefore, while there are methods to counter quantum risks, they also introduce issues, primarily related to performance and cost overheads during large-scale deployment.

BTC dips 0.50% over 15 minutes: high-leverage liquidation in the derivatives market triggers a passive pullback in spot
2026-04-16 13:30 to 13:45 (UTC), the BTC price fluctuated within the range of 74481.3 to 75000.0 USDT, with a return of -0.50% over 15 minutes and a swing of 0.69%. During this round of abnormal movement, market attention increased, shown by intensified short-term volatility, but it did not trigger widespread panic.
The main driver of this abnormal movement is localized forced liquidation under the high-leverage positioning environment in the derivatives market. Existing data shows that BTC perpetual futures open interest has been running at consistently high levels; leverage has accumulated in the market. Within the abnormal-movement window, long leverage is passively deleveraged, which triggers a liquidation cascade and, in turn, causes the spot price to passively dip. ETF fund flows remain neutral, contrasting with net outflows of large on-chain funds, further confirming that this price decline is mainly driven by endogenous risk release within the derivatives market.
In addition, daily-level data shows that large addresses (\u003e$10M) continue to record net outflows, with a total amount of -12,987.03 BTC. This should have provided support for the price, but during the abnormal movement period, no large-scale concentrated sell-off or a surge in on-chain activity has been observed. On the ETF side, mainstream ETF fund flows show no significant abnormal movement, indicating that institutions have not engaged in trend-based selling. Spot and derivatives trading volumes remain high. The position structures of some top platforms are highly concentrated, and with multiple factors resonating simultaneously, the effect of localized forced liquidation is amplified, which then transmits to the spot market.
The market is still in a high-leverage operating phase. Investors should be alert to the risk of a new round of forced liquidation pressure brought on by amplified future volatility. Focus on indicators such as the exchanges’ BTC net inflow/outflow, minute-level large transfers, derivatives market positions, funding rates, and liquidation volume. If there is a sudden change in fund flows on the derivatives or ETF side, there may be systemic downside risk. In the short term, the risk of sharply fluctuating market conditions is prominent, and investors should closely monitor subsequent market data and on-chain developments.
