Adam Back Says Quantum Threat To Bitcoin Is Decades Away

Blockstream CEO Adam Back pushed back on concerns that quantum computing poses an imminent threat to Bitcoin’s cryptographic security, arguing that current progress in the field remains far from the level required to break real-world encryption.

Speaking in an interview with Bloomberg, Back noted that much of today’s quantum research is still in its early experimental phase. He pointed to the limited capabilities of existing quantum hardware, which often lacks full error correction and has only demonstrated trivial computations. “The biggest calculation it’s performed is factoring 21 into 7 times 3,” he said, emphasizing that today’s machines remain closer to laboratory…

Nunchuk Releases Open-Source Tools For Bitcoin Agents With Bounded Authority

Nunchuk has released two open-source repositories aimed at reshaping how AI agents interact with Bitcoin wallets, introducing a model that limits agent control while preserving human oversight.

The release includes Nunchuk CLI, a command-line interface for managing Bitcoin wallets, and a companion “Agent Skills” repository designed to help AI systems operate the CLI across common workflows. Both tools are licensed under MIT and target developers building automated financial systems on Bitcoin, Nunchuk said. 

The core premise challenges a growing trend in AI wallet design. Rather than granting agents full control over funds with basic safeguards, Nunchuk proposes a shared…

XRP Disappoints In Q1 With 27% Drop: What’s Going On?

XRP (CRYPTO: XRP) has declined about 29% in recent weeks, even as institutional inflows surge to their highest levels since December 2025.

Trader Notes: Analyst Javon Marks suggests XRP could reach a measured move target just below $17, implying a potential gain of more than 1,100%. The projection is based on a large pennant breakout pattern, like XRP’s 2017 rally.

Another analyst, Cantonese Cat, said that if XRP reclaims its previous all-time high, the next key level could be around $6, aligned with the 1.272 Fibonacci extension. The analyst also noted that XRP may have already formed a capitulation bottom on higher timeframes.

Statistics: Data from CoinShares shows XRP recorded $116.9…

Bitcoin Tracks Gold At 60% As Iran War Triggers $110M Liquidation Storm – Grayscale Bitcoin Mini Trust (B

The main driver behind this is the growing conflict between the U.S and Iran. The tension is spreading uncertainty across financial markets, and crypto investors are pulling back as global risk sentiment weakens.

For investors trying to make sense of the chaos, the most important data point right now is not the price. It is the correlation. Bitcoin is currently tracking gold at a 60% correlation, a figure that fundamentally changes how you should be reading every candle on the chart.

What a 60% Gold Correlation Actually Means

Correlation in financial markets is measured on a scale of -1 to +1. A reading of 0 means two assets move independently. A reading of +1 means they move in perfect…

Bernstein Pushes Back On Bitcoin Quantum Threat Fears, Says It’s Not A Crisis: Report

Wall Street research firm Bernstein is pushing back on alarm over quantum computing’s threat to Bitcoin, framing the challenge as a scheduled protocol evolution rather than a crisis in waiting.

In a note to clients on Wednesday, analysts led by Gautam Chhugani acknowledged that cryptographically relevant quantum computers (CRQCs) pose a genuine challenge to Bitcoin and the broader digital asset ecosystem — but stopped short of treating that challenge as an emergency. The team estimates Bitcoin and other crypto protocols have three to five years to implement post-quantum security measures, a window they describe as sufficient given current technical and cost constraints.

XRP Falls 2%, But ETFs See $3.32M Inflows: What’s Going On?

XRP (CRYPTO: XRP) slipped 2% on Wednesday after touching a session high of $1.39, giving back most of the prior session’s 5% gain, yet U.S.-listed XRP spot ETFs recorded $3.32 million in net inflows on April 7.

The Quantum Safety Check

Roughly 300,000 accounts on XRP holding 2.4 billion XRP never transacted, meaning their public keys are unknown and quantum safe. 

Only 2 accounts with larger holdings of 21 million XRP are dormant (inactive over 5 years) and have their public keys exposed.

Dormant vulnerable XRP whales are almost nonexistent. The rest are active and have their public keys exposed but can reasonably rotate keys if needed. 

This differs from Bitcoin (CRYPTO: BTC) where…

Strategy’s New Product Grew Faster Than The iPhone And Google Ads Combined – Strategy (NASDAQ:MSTR)

The Seven-Month Sprint

Strategy launched Stretch at the end of July 2025. From that point to mid-March 2026, the product grew to $5 billion. 

Apple’s iPhone took about a year to reach $5 billion in cumulative revenue. Google Ads took about four years.

“From a pure product perspective, you could argue that Stretch is the fastest growing product in the history of the world,” said Fong Lee, CEO of Strategy.

Compared to ETFs, the gold ETF launched in the early 2000s took four to five years to reach $5 billion in assets under management. 

How It Works

Stretch is a perpetual preferred stock that pays an 11.5% annual yield in monthly distributions. 

The payments qualify as return of capital,…

NYT Names Adam Back As Bitcoin’s Creator. Back Says No

The New York Times published an investigation Tuesday arguing that Adam Back, a British cryptographer and longtime figure in the Bitcoin community, is the most credible candidate yet for Satoshi Nakamoto — the pseudonymous inventor of Bitcoin. 

Back denied the claim before the story ran, denied it inside the story, and denied it again in a public post on X after publication.

“I’m not satoshi, but I was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas,” Back wrote on… Read more on BitcoinMagazine
