Bitcoin gets its first working prototype of quantum-resistant wallet rescue tool

Published

Key initiatives aimed at quantum-proofing the world's largest blockchain

A top Bitcoin developer says he’s built something the community has debated for years but never actually produced: a way to rescue ordinary wallets if the network is ever forced to defend itself against a quantum computer.

Olaoluwa “Roasbeef” Osuntokun, chief technology officer at Lightning Labs, unveiled the working prototype in an April 8 post to the Bitcoin developer mailing list. The tool targets a specific and uncomfortable flaw in Bitcoin’s long-term defense plan, a widely discussed “emergency brake” upgrade designed to protect the network from quantum attacks could also lock millions of users out of their own funds. Osuntokun’s proposal is an escape hatch.

Bitcoin relies on a form of encryption that could, in theory, be broken by sufficiently powerful quantum computers. If that happens, public data already visible on the blockchain could be turned into private keys, allowing attackers to seize funds.

One leading proposal, known as BIP-360, was merged into Bitcoin’s improvement-proposal repository in February as a draft. It would give users a new, quantum-resistant type of wallet to migrate their funds into ahead of any threat.

But migration takes time, and not everyone will move in time. That’s why developers have also been discussing a more drastic backstop — the “emergency brake.”

Every Bitcoin transaction today is authorized by a digital signature, a piece of cryptographic math that proves the sender owns the coins. Those signatures are exactly what a quantum computer would be able to forge.

The emergency brake would shut off Bitcoin’s current signature system network-wide, before an attacker could start draining wallets. Think of it as cutting power to the locks when you realize the keys have been copied.

The problem is what happens to everyone still inside. Most modern wallets — especially the single-user Taproot wallets introduced to Bitcoin in 2021 and now common across the ecosystem — rely on that signature system and nothing else to authorize spending. If it gets switched off, those wallets have no second way to prove ownership.

The coins inside them would be stranded, untouchable even by their rightful owners. The same upgrade designed to protect users could also freeze them out permanently.

Osuntokun’s prototype is designed to give those wallets a second way. Instead of proving ownership with a digital signature — the very mechanism a quantum attack would break and the emergency upgrade would disable — his system lets a user mathematically prove they were the one who originally created the wallet, using the secret “seed” that every Bitcoin wallet is generated from.

Crucially, the proof doesn’t require revealing the seed itself, so using it to rescue one wallet doesn’t compromise any others derived from the same seed. In effect, it replaces “I can sign this transaction” with “I can prove this wallet came from me.”

The prototype is already functional. Running on a high-end consumer MacBook, generating the proof took about 55 seconds, while verification took under two seconds. The resulting proof file was roughly 1.7 MB, about the size of a high-resolution image. Osuntokun said the system was built as a side project and remains unoptimized.

Right now there is no formal proposal to add it to the Bitcoin blockchain, no deployment timeline, and developers remain divided on how urgent the quantum threat actually is.

Academic researchers note that many widely cited quantum “breakthroughs” rely on simplified test conditions, and large-scale attacks on Bitcoin’s mining system would run into hard physical limits. But the risk to exposed wallets is considered real enough that developers have been sketching defensive upgrades for years.

Markets reflect that uncertainty. On Polymarket, traders currently assign roughly a 28% chance that BIP-360 is implemented by 2027.

But the prototype closes a gap that had lingered in theory: how to protect Bitcoin from a future threat without the collateral damage of locking users out of their wallets.

Canary Capital Pushes Crypto ETF Frontier Further With PEPE Filing

Published

on

Canary Capital Group filed an S-1 registration statement with the US Securities and Exchange Commission (SEC) to launch an exchange-traded fund (ETF) tracking PEPE Coin (PEPE).

The proposed Canary PEPE ETF would hold the Ethereum (ETH)-based meme coin directly, mirroring the structure of existing spot ETFs. 

According to the filing, the Canary PEPE ETF would sell or redeem shares in baskets of 10,000 units. The prospectus leaves the listing exchange, pricing benchmark, and digital asset custodian unnamed.

“The Trust’s investment objective is to seek to provide exposure to the price of PEPE Coin (“PEPE”) held by the Trust, less the expenses of the Trust’s operations and other liabilities,” the filing reads.

A small portion of the Trust’s assets, capped at 5%, would initially be held in ETH to cover transaction fees on Ethereum. However, the asset manager stressed that the ETF will not “hold ETH for investment purposes.”

In addition to PEPE, Canary submitted an S-1 for a Mog Coin (MOG) ETF in November 2025 and has filed for funds tracking Pudgy Penguins (PENGU), Axelar (AXL), and others.

For now, Dogecoin (DOGE) is the only meme coin with live ETFs in the US. Three spot funds from Grayscale, 21Shares, and Bitwise trade on the NYSE and the Nasdaq.

However, demand remains thin. SoSoValue data shows that cumulative net inflows across all three totaled just $7.64 million as of April 8, with combined daily volume barely topping $209,000

Meanwhile, the news had little impact on PEPE’s price. The meme coin traded near $0.0000035 at press time.

The token fell by more than 4.8% over 24 hours as broader geopolitical uncertainty continued to pressure risk assets.

Bitcoin recovery rally fades as liquidations and macro risks return

Bitcoin recovery rally fades as liquidations and macro risks return

Bitcoin’s push toward $73,000 has lost traction, leaving the market exposed to renewed downside risks as macro uncertainty returned.

Summary

  • Bitcoin rally to $72,698 stalled at resistance, triggering over $150M in long liquidations.
  • Ceasefire tensions resurfaced after officials called the deal a “fragile truce” and reports pointed to violations.

The flagship cryptocurrency climbed to a weekly high of $72,698 on Tuesday, gaining nearly 6% in under four hours as global markets responded to news of a two-week ceasefire agreement between the United States and Iran. 

Bitcoin rose as risk sentiment improved, as expectations that the Strait of Hormuz could reopen helped ease supply concerns.

However, the short period of euphoria faded quickly near the $72,000 level. A wave of liquidations hit derivatives markets at that point. More than $150 million in long positions were wiped out, confirming that bullish conviction remains weak at higher levels.

Price action also continued to track movements in traditional markets, with Bitcoin showing a tight correlation to S&P 500 futures during the rally. The link points to a market still heavily influenced by macro headlines rather than internal crypto-specific drivers.

Now, tensions surrounding the ceasefire have since raised fresh concerns. US Vice President JD Vance described the agreement as a “fragile truce,” while developments on the ground painted a less stable picture.

Reports from the Levant indicated repeated violations, with Israel launching “Operation Eternal Darkness” targeting underground infrastructure tied to Hezbollah in Lebanon.

Israeli officials maintained that their operations fall outside the scope of the Iran ceasefire, citing strategic independence.

Further strain came after Iran’s parliamentary speaker accused Washington of violating “the spirit of the roadmap,” warning that Tehran could resume strikes if attacks on its allies continue. 

Any breakdown in the agreement risks reigniting conflict, a scenario that could weigh heavily on risk assets, including cryptocurrencies.

Market positioning remains sensitive to these developments. Bitcoin has struggled to secure a firm hold above $70,000 over the past week, and a sustained move below that level could open the door for a retest of the $64,000 support zone.

At last check, Bitcoin was trading just above $71,000, down less than 1% over the past 24 hours, as traders weighed the combined impact of geopolitical instability and shifting policy expectations.

Attention has also turned to monetary policy signals. Minutes from the Federal Reserve’s March 17–18 meeting showed that officials voted 11–1 to keep rates unchanged at 3.5% to 3.75%, while leaving the door open for potential cuts later this year.

The details of the discussion, however, pointed to caution. Policymakers signaled that any move toward easing would depend on inflation staying contained, particularly as energy prices remain a concern. Some members indicated that a tighter policy could still be required if price pressures persist.

Interest rate expectations continue to play a key role in crypto market sentiment. While lower rates tend to support risk assets, uncertainty around the timing of cuts can dampen demand and increase volatility.

Despite all the negative geopolitical headwinds, Bitcoin price could find some support and potentially decouple from traditional risk-off sentiment if reports of Iran circumventing traditional financial sanctions by using Bitcoin to facilitate trade at the Strait of Hormuz are confirmed.

On April 8, several regional maritime intelligence outlets reported that the Iranian Revolutionary Guard Corps (IRGC) was charging transit fees for commercial vessels with the option for direct payment in Bitcoin. If this is confirmed, it could help keep momentum afloat by providing a fundamental floor of demand in the short-term.

Polygon Reportedly Targets $100 Million for Stablecoin Venture as Crypto Market Stalls

Published

on

Polygon Labs is reportedly in early-stage fundraising discussions to back a new stablecoin payments business, aiming to raise as much as $100 million.

The firm is looking to sell equity shares worth between $50 million and $100 million in the new stablecoin unit.

The fundraising push comes as broader crypto markets remain under pressure. The new venture might be a strategic move for the firm “to diversify out of a market that has stalled,” The Information noted.

In January, Polygon signed definitive agreements to acquire payments firm Coinme and wallet infrastructure provider Sequence.

“Together with Polygon’s blockchain rails, these acquisitions complete the core infrastructure required to offer regulated stablecoin payments in the U.S. and beyond, forming the foundation for Open Money Stack,” the announcement read.

The timing of Polygon’s pivot aligns with strong growth across the stablecoin sector. In 2025, stablecoins processed $28 trillion in real economic volume, according to Chainalysis. 

BeInCrypto also reported that stablecoin monthly transaction volume then reached $7.2 trillion in February 2026, overtaking the Automated Clearing House (ACH) network’s $6.8 trillion for the first time.

Industry projections reinforce the long-term thesis. At XRP Tokyo 2026, Ripple shared a flyer projecting $33 trillion in onchain stablecoin volume for 2026. Meanwhile, Chainalysis estimates that adjusted stablecoin volume could reach $719 trillion by 2035 through organic growth alone.

Stablecoin Volumes Could Hit $1.5 Quadrillion in a Decade: Chainalysis

Stablecoin Volumes Could Hit $1.5 Quadrillion in a Decade: Chainalysis

Blockchain analysis firm Chainalysis estimates that stablecoin volumes could hit a lofty $1.5 quadrillion within the next decade, beating the total volume of global cross-border payments today. 

In a report on Wednesday, the Chainalysis team said that adjusted stablecoin volume could hit $719 trillion by 2035 just through organic growth, up from $28 trillion in 2025.

However, this figure could double by 2035 if two major catalysts come into play, said Chainalysis — the baby boomer generation passing $100 trillion in wealth to a crypto-loving generation and stablecoins knocking over traditional payment rails to become the default payment infrastructure. 

“Factor in these catalysts, and our projections change: 2035 volumes could approach $1.5 quadrillion, a figure that would surpass the estimated $1 quadrillion in global cross-border payments today,” Chainalysis said.

The figure, should it come to pass, suggests that the stablecoin industry is extremely undervalued. It could be seen as a very generous estimate, as it would eclipse the annual volume of cross-border remittances, which was estimated at $865 billion in 2023 and $905 billion in 2024.

The number is even higher than World Population Review’s latest estimate of the total value of all global assets across banks, property and cash, which is around $662 trillion.

Even the $719 trillion would mean that stablecoins would need to continue their compound annual growth rate of 133% for the next decade. 

$1.5 quadrillion stablecoin volume possible: Analyst

Rachael Lucas, a crypto analyst at Australian crypto exchange BTC Markets, told Cointelegraph $1.5 quadrillion is “a ceiling-case scenario, not a base case,” but said it could be possible, because growth is accelerating. 

She also noted that volume measures how many times money moves, not how much exists; the same dollar can settle dozens of transactions a day.

“The infrastructure is being built right now. Stripe acquiring Bridge, Mastercard partnering with BVNK, these are operational bets, not experiments. Add regulatory clarity from the GENIUS Act, and institutional participation can scale in ways that simply were not possible before,” she added.

“The generational wealth transfer will do the rest. Millennials and Gen Z are the first generations for whom on-chain is a default, not a deliberate choice.”

A January OKX survey found that among younger Americans, 40% of Gen Z and 36% of Millennials plan to increase their crypto activity this year, compared with 11% of Boomers.

Meanwhile, stablecoins are frequently cited as a major driver of crypto adoption. A September report by EY-Parthenon, the strategy consulting division of Ernst & Young, found that 13% of financial institutions and corporates globally use stablecoins and 54% of non-users expect to adopt them within 12 months.
