Adam Back has denied claims that he is Satoshi Nakamoto after a New York Times story argued that the British cryptographer is the strongest candidate yet for Bitcoin’s BTC$71,495.98 pseudonymous creator.

In a post on X after the article was published, Back said his long record in cryptography, privacy tools and electronic cash research explains why reporters keep finding links between his work and Bitcoin’s design.

“I’m not satoshi,” Back wrote. He said he had been “early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash,” and that his work from about 1992 onward, including discussions on the cypherpunks mailing list, led to Hashcash and other ideas later echoed in Bitcoin.

Back, said NYT reporter John Carreyrou, had found “many interesting bitcoin analogs in early attempts to create a decentralized ecash,” adding that early researchers explored concepts such as peer-to-peer systems, proof-of-work, and routing models that looked like prototypes for Bitcoin.

He also disputed one line in the story that treated a comment he made in an interview as a possible slip. Back’s remark — “I’m not saying I’m good with words, but I sure did a lot of yakking on these lists actually” — referred to confirmation bias. Because he wrote so often about electronic cash, he said, his old comments are easier to match with Satoshi’s than those of others who posted far less.

“The rest is a combination of coincidence and similar phrases from people with similar experience and interests,” Back wrote.

He added that he does not know who Satoshi is and said that it may be good for Bitcoin. In his view, the mystery helps frame Bitcoin as “a new asset class, the mathematically scarce digital commodity.”

Others also questioned the conclusions. Joe Weisenthal, a Bloomberg columnist and co-host of the Odd Lots podcast, said he was “not 100% convinced by the evidence or the conclusion.”

“The stylometry is interesting, but on content, ofc all the cypherpunks had similar thoughts on politics and privacy and the architecture of the internet,” he wrote on X. He also questioned why Back would speak openly about earlier work like Hashcash under his real name but use strict anonymity for Bitcoin.

“None of us are that consistent with hyphenization,” Weisenthal added, arguing that shared writing quirks may not be meaningful. He noted that Back was already among those closest to assembling Bitcoin-like ideas before its launch, which could explain his later involvement.

The question of Satoshi’s identity has drawn speculation for years. Several books, documentaries and articles have claimed to have solved it, only for those cases to unravel or fail to persuade the wider Bitcoin community. In 2024, one high-profile documentary pointed to developer Peter Todd, who denied the claim.

Nicholas Gregory, a U.K.-based early Bitcoin participant, also pushed back on the latest theory.

“I don’t believe Adam Back is Satoshi based on my personal interactions with him,” Gregory said. “However, if he were, we would have to respect the extraordinary lengths he has gone to in order to ensure no one thinks it’s him. In that case, we should honor his clear desire for privacy.”

Gregory said the longer the search continues, the more extreme the theories become. He added that many reporters miss key parts of Bitcoin’s early history and make avoidable errors.

He also warned that publicly identifying Satoshi could put that person and their family at risk.

Key takeaways

• BTC is up 4% and is now trading above $71k.
• The rally could push Bitcoin’s price above $76k for the first time since March 16.

Bitcoin and crypto market surge following U.S.-Iran ceasefire announcement

Bitcoin (BTC), Ethereum (ETH), and the broader cryptocurrency market experienced a significant rise over the last 24 hours after the U.S. and Iran reached a ceasefire agreement.

At press time, Bitcoin was trading at approximately $71,640, up 4.3% in the last 24 hours. Earlier in the day, the cryptocurrency briefly surpassed $72,700, marking its highest value since March 18.

Ethereum gained 6.7%, reaching $2,257, while XRP increased 5.8% to $1.37. Solana surged 6.5%, hitting $84.81. The overall crypto market was up 3.95% during the same period.

The surge coincided with President Donald Trump’s announcement that the U.S. and Iran had agreed to a two-week “double-sided ceasefire.” Trump, who had previously warned of a possible military response if Iran failed to reopen the Strait of Hormuz, emphasized that the ceasefire was a result of having met all military objectives and being close to a long-term peace agreement.

Iran’s official statement confirmed its commitment to allowing safe passage through the Strait of Hormuz, the world’s most vital oil trade route. This had previously caused significant volatility in global oil prices and disrupted supply chains.

BTC eyes $76k as bullish momentum persists

The BTC/USD 4-hour chart remains bearish and efficient despite the recent rally. The leading cryptocurrency has surpassed the $69,200 resistance level and could challenge the swing high of $76,000 over the next few hours or days.

The momentum indicators show that the bulls are currently in control of the market. The Relative Strength Index (RSI) on the 4-hour chart reads 70, approaching the overbought condition, indicating that the bulls are in control.

The MACD lines are also within the positive territory, reaffirming the bullish bias. If the rally persists, BTC could retest the $76,000 resistance level for the first time since March 16. Surpassing this resistance level would pave the way for Bitcoin to surge toward the $80k psychological zone.

However, if the bulls fail to capitalize on this rally, Bitcoin will find immediate support around the Tuesday low of $67,719.

Key Highlights

• Japanese regulators authorize SBI Ripple Asia’s XRPL Token Platform
• Platform facilitates regulated token creation under Japanese financial legislation
• Businesses gain blockchain access through streamlined API connectivity
• System operates within Japan’s prepaid payment regulatory structure
• Strategic focus includes real-world applications and international payment corridors

Following regulatory authorization from Japanese financial authorities, SBI Ripple Asia has officially introduced its XRPL Token Platform. This blockchain-based infrastructure enables organizations to issue digital tokens while maintaining full compliance with Japan’s financial regulatory framework. The development represents a significant milestone in merging distributed ledger technology with traditional payment ecosystems.

Blockchain Platform Debuts with Enterprise API Capabilities

SBI Ripple Asia has finalized its XRPL Token Platform utilizing the XRP Ledger as its foundational technology. This infrastructure provides organizations with capabilities to create and administer digital tokens through on-chain mechanisms. Enterprise clients can integrate blockchain functionality into their existing systems via application programming interfaces without disrupting end-user experiences.

The platform architecture facilitates smooth incorporation with established digital services and customer-facing applications. End users gain access to tokenized financial instruments while maintaining familiar interaction patterns. Proprietary wallet management technology embedded in the system delivers robust security protocols for digital asset custody.

Compliance with Japan’s Payment Services Act forms a core component of the XRPL Token Platform’s operational framework. Organizations can launch tokenized prepaid financial products within established regulatory boundaries. The infrastructure supports enterprise-grade scalability across diverse operational contexts.

Official Registration Unlocks Compliant Digital Payment Products

On March 26, 2026, SBI Ripple Asia obtained official registration as an authorized issuer of third-party prepaid payment instruments. This regulatory milestone empowers the XRPL Token Platform to launch compliant digital financial offerings. The company now operates as a legitimate bridge connecting blockchain innovation with supervised financial services.

This official status reinforces the legal infrastructure supporting the XRPL Token Platform within Japan’s financial sector. The authorization permits issuance of prepaid payment products underpinned by blockchain tokens. Regulatory oversight mechanisms remain fully integrated throughout the operational framework.

Through this positioning, SBI Ripple Asia establishes itself within Japan’s regulated digital asset landscape. The platform supports expanded utilization of blockchain-powered payment solutions. This framework demonstrates increasing institutional commitment toward compliant tokenization strategies.

Strategic Roadmap Emphasizes Practical Implementation and Regional Payment Networks

SBI Ripple Asia intends to implement the XRPL Token Platform across geographically focused economic areas including tourism-intensive regions. The infrastructure will connect consumer transactions with digital reward mechanisms and payment processing systems. Novel approaches to customer loyalty initiatives and transaction-based incentives become feasible through this framework.

The platform aims to enhance operational scalability and reduce transaction costs throughout collaborative business networks. Strategic partnerships with regional businesses and municipal organizations form a central component of the expansion strategy. These alliances will accelerate implementation in tangible commercial settings.

SBI Ripple Asia maintains active research initiatives focused on XRPL applications within Asian payment channels. Collaborative investigation with South Korea’s DSRV targets improvements in international money transfer systems. The XRPL Token Platform holds potential to optimize transaction speed and cost-effectiveness for Japan-South Korea payment flows.

Wall Street broker Bernstein said the rise of quantum computing poses a credible but manageable threat to Bitcoin and the broader crypto ecosystem, as recent breakthroughs compress timelines for potential attacks on modern cryptography.

Advances such as Google Quantum AI’s reported reduction in qubit requirements suggest the risk is no longer a distant, decade-long concern, the broker noted. Still, the firm cautioned that scaling quantum systems to the level needed to break widely used encryption remains a complex, multi-step challenge.

“Quantum should be seen as a medium to long term system upgrade cycle rather than a risk,” analysts led by Gautam Chhugani said in the Wednesday report.

Quantum computing uses the principles of quantum mechanics rather than classical physics. Instead of binary bits, it relies on qubits that can exist in multiple states at once, a property known as superposition, allowing many possibilities to be processed simultaneously.

Combined with entanglement, this enables quantum systems to solve certain problems, such as breaking encryption, far more efficiently than classical computers.

Quantum computers could eventually weaken cryptographic systems like elliptic curve encryption, which underpin crypto wallets, by solving problems beyond the reach of classical machines. However, the report said the threat spans industries from finance to defense and should be viewed as a manageable, long-term risk rather than an existential one for Bitcoin.

Exposure is concentrated in roughly 1.7 million BTC held in older, “legacy” wallets, while newer practices and protocols reduce vulnerability. Bitcoin mining, which relies on SHA-based hashing, remains effectively secure even in advanced quantum scenarios, the broker said.

Bernstein expects the crypto industry to have sufficient time, around three to five years, to transition toward post-quantum cryptography, with upgrades such as new wallet standards, reduced address reuse and key rotation already under discussion.

One recent academic paper said that attacking the Bitcoin blockchain through quantum mining would demand the energy output of a star.

• The accusation: Gracy Chen, Bitget CEO, publicly called Hyperliquid an ‘overmarketed’ fake DEX on April 7, warning of systemic risks comparable to FTX and describing it as an ‘offshore CEX with no KYC/AML.’
• The trigger: Hyperliquid’s small validator set unanimously delisted the JELLY memecoin perp market on March 26 and force-settled positions at $0.0095 after an attacker used a $6M short to exploit the HLP vault – exposing the platform’s centralized emergency override capability.
• The structural critique: Chen argued that Hyperliquid’s mixed vaults expose all users to collective risk from individual manipulators, and that foundation-level intervention in open markets sets a ‘dangerous precedent.’
• The volume context: Hyperliquid’s HYPE token and platform growth represent a direct threat to CEX perp revenue – making Chen’s critique land somewhere between principled concern and competitive self-interest.
• Industry split: BitMEX co-founder Arthur Hayes echoed decentralization concerns but downplayed long-term damage; Hyperliquid’s community pushed back hard, accusing Chen of conflating valid critique with CEX protectionism.
• What’s next: Hyperliquid has flagged validator expansions and HLP upgrades post-JELLY; Bitget’s Q2 2026 volume numbers will tell whether the controversy moved any market share.

Wall Street investment bank JPMorgan (JPM) said the pace of capital flowing into digital assets slowed markedly in the first quarter of 2026, with total inflows estimated at around $11 billion.

That implies an annualized run rate of roughly $44 billion, about one-third of the pace seen in 2025, according to the report published last week.

“Investor flows, either retail or institutional, have been small or even negative YTD with the bulk of the digital asset flow in Q1’26 stemming from Strategy’s (MSTR) bitcoin BTC$71,726.66 purchases and concentrated crypto VC funding,” wrote analysts led by Nikolaos Panigirtzoglou.

Crypto markets had a volatile and broadly negative first quarter, with prices and market value retreating sharply amid a risk-off backdrop. Total crypto market capitalization fell roughly 20% over the period, while bitcoin dropped around 23% and ether (ETH) declined more than 30%, marking one of the weakest first-quarter performances in years.

The selloff was driven by macroeconomic and geopolitical pressures, triggering liquidations and a broad pullback in risk assets, with altcoins hit even harder.

Despite the downturn, prices stabilized toward the end of the quarter, with bitcoin consolidating near the $70,000 level as ETF demand improved and some pockets of the market, such as select altcoins and onchain activity, showed resilience.

The bank’s estimate aggregates crypto fund flows, Chicago Mercantile Exchange (CME) futures positioning, venture capital fundraising and corporate treasury activity, including bitcoin BTC$71,726.66 purchases by firms such as Strategy.

The analysts said investor-driven flows were notably weak. Positioning in bitcoin and ether CME futures softened versus 2024 and 2025, suggesting institutional demand may have turned slightly negative year-to-date. Spot bitcoin and ether exchange-traded funds (ETFs) also saw net outflows during the quarter, concentrated in January, before a modest rebound in bitcoin ETF inflows in March.

The bank’s analysts attributed most of the quarter’s inflows to corporate treasury activity and venture funding. Strategy remained a dominant buyer, funding bitcoin purchases largely through equity issuance, while signaling continued reliance on stock and preferred issuance to finance accumulation. Other corporate holders were more defensive, with some selling bitcoin to fund buybacks.

Bitcoin miners were net sellers during the quarter, the report said, as firms sold holdings or used them as collateral to shore up liquidity, fund capital expenditures or manage liabilities. The analysts characterized the selling as driven by tighter financing conditions and balance sheet discipline rather than distress.

Crypto venture capital was a relative bright spot. Funding tracked an annualized pace above the prior two years, though activity was increasingly concentrated in fewer, larger deals led by established firms. Capital continued to rotate toward infrastructure, stablecoins, payments and tokenization, with less interest in gaming, non-fungible tokens (NFTs) and exchange-related projects, the report added.

Diplomatic Signals Revive Cheer in the Market

Authorities on both sides, as well as regional mediators, are still negotiating conditions of a temporary truce. In addition, the suggested ceasefire would open significant trade routes and take the strain off world markets. These news items favored returns in risk assets, such as cryptocurrencies and US stock futures. The US President Donald Trump spoke about the situation at a regular press conference, pointing to continuing negotiations. Moreover, he also prolonged a deadline concerning possible military intervention, which indicated the possibility of further negotiations. There was a response by market participants to these updates as de-escalation expectations rose.

The decrease in oil prices was caused by the expectation of a ceasefire, which reduced worries about supply disruption. Prices were on a downward swing, with energy markets showing improved mood. Therefore, the fall in oil prices helped the recovery of Bitcoin and the subsequent rise of the market. The surge in the value of Bitcoin to over 70,000 caused a run-up in the values of other leading digital currencies such as Ethereum, XRP, Solana and Cardano. Also, the wider crypto market saw high buying behaviour with prices rising accordingly. This collaborative action emphasised the impact of Bitcoin on the general market trend.

Due to the price explosion, there was a dramatic short sale in the derivatives market within a short time. Additionally, the volume of trading was high, indicating that more traders were involved. Statistics also revealed that there was an increase in futures open interest, meaning that more people are taking leveraged positions. The Strait of Hormuz remains a focal point of developments in the markets because of its significance in the oil supply in the world market. Also, any advancement in the negotiations can affect the energy market and financial market in the short term. This relationship continues to bind geopolitical events to crypto price changes.

South Korea’s ruling Democratic Party is reportedly preparing a draft bill that would classify stablecoins as foreign exchange payment instruments and require tokenized real-world assets (RWAs) to be backed by assets held in trust. 

Citing an integrated draft of the proposed Digital Asset Basic Act, the Seoul Economic Daily reported on Wednesday that stablecoins used in cross-border transactions would be treated as “means of payment” under the Foreign Exchange Transactions Act, placing related businesses under oversight even without separate registration.

The draft bill would also require issuers of tokenized RWAs to place underlying assets in managed trusts under the Capital Markets Act. 

If implemented, the changes would bring stablecoins and tokenized RWAs under existing financial rules, tightening oversight of cross-border flows and setting custody requirements for underlying assets.

Cointelegraph could not independently verify the draft provisions through a public National Assembly filing as of Wednesday. 

Stablecoin draft targets cross-border use, bans interest

The Seoul Economic Daily also reported that the draft would exempt certain stablecoin payments for goods and services from foreign exchange reporting requirements within a defined scope.  

The draft also reportedly bars issuers from paying interest to holders of value-stable digital assets, regardless of how the incentive is labeled. It would also require the Financial Services Commission to establish technical standards aimed at ensuring interoperability across digital asset networks, the report said.

The reported approach aligns with earlier concerns raised by South Korea’s central bank.

On Jan. 27, Bank of Korea Governor Lee Chang-yong warned that Korean won-denominated stablecoins could complicate capital-flow management and foreign exchange stability, adding to the debate over how domestic stablecoins should be regulated.

New draft would move tokenization into existing structures

On the RWA side, the draft would reportedly require issuers to place linked assets in managed trusts under the Capital Markets Act. The requirement would tie tokenized asset issuance to existing custody frameworks, according to the report. 

According to the report, key issues like exchange ownership limits and bank-related requirements for stablecoin issuers were not included in the draft.

The omissions come amid broader disagreements over how the bill should regulate stablecoins. On Dec. 31, disagreements over stablecoin oversight and issuer requirements had delayed the Digital Asset Basic Act.
