Binance’s CZ Offers OKX Founder $1 Billion Bet Over Divorce Dispute

Published

on

Binance co-founder Changpeng Zhao (CZ) confirmed he is officially divorced and offered OKX founder Star Xu a $1 billion bet to prove it.

The challenge came after Xu questioned CZ’s marital status as part of a broader dispute triggered by CZ’s 457-page memoir “Freedom of Money,” released on April 8.

Star Xu Questions CZ’s Marital Status

Xu demanded that CZ produce a divorce agreement signed by both parties.

He said he would publicly apologize if CZ could present the document. If not, he argued, the claim would amount to public misrepresentation.

I typically ignore all these false claims and attacks. But… You can apologize now. I am officially divorced,” wrote CZ.

CZ responded by confirming his divorce and proposing a permanent wager of $1 billion. He stated he would not share legal documents online out of respect for his ex-wife’s privacy.

However, he offered to have lawyers verify the agreement if Xu accepted the bet.

“I am happy to bet $1 billion USD (or any number you choose) that: I am officially divorced (way before today),” CZ added.

He gave Xu a 24-hour window to respond, adding that silence would reveal who had been misleading the public.

A Feud Rooted in a Decade of Rivalry

The divorce dispute is the latest front in a conflict that dates back to 2014. CZ served as chief technology officer at OKCoin, the predecessor to OKX.

Their falling out over equity, a Bitcoin.com domain contract, and forgery allegations have resurfaced multiple times.

CZ’s memoir also claims Huobi founder Li Lin told him in 2025 that Xu had reported him to Chinese authorities. Xu has denied that claim.

“Both OKX and Binance are regulated by multiple regulators. As the UBO of a regulated company, publicly offering a $1 billion bet is hardly professional conduct,” Xu responded to CZ’s invitation.

The OKX executive also called on the attention of Binance’s regulators to CZ’s offer, questioning whether Changpeng Zhao’s Binance stake has been legally separated with his ex-wife.

“Bill Gates and Jeff Bezos have already shown what proper asset separation looks like in a divorce,” he added.

Yi He, the co-CEO of Binance, is the long-term life partner (romantic and business) and the mother of three of CZ’s children. Reportedly, CZ has five kids total, two from his previous marriage.

They met in 2014 while working at the crypto exchange OKCoin (she recruited him), and became a couple around that time, and co-founded Binance together in 2017.

Amid the ongoing talks between CZ and Star Xu, Yi He has come to her own defense, highlighting her role as the second largest shareholder and Co-CEO of Binance.

“I’m not some delicate wife literature female protagonist; I’m the second largest shareholder and Co-CEO of Binance who continues to fully suppress competitors even after CZ stepped down,” she articulated.

StarkWare Researcher Publishes Quantum-Safe Bitcoin Transaction Scheme

StarkWare Researcher Publishes Quantum-Safe Bitcoin Transaction Scheme

The QSB scheme uses only existing Bitcoin consensus rules, sidestepping the network’s contentious upgrade process.

A researcher at StarkWare has published an open-source scheme for making Bitcoin transactions resistant to quantum computing attacks using only the network’s existing consensus rules — requiring no softfork, no protocol upgrade, and no community-wide coordination.

The project, called Quantum Safe Bitcoin (QSB), was released on GitHub by Avihu Levy, StarkWare’s chief product officer and a leading Bitcoin researcher at the firm who previously co-authored ColliderScript, a protocol for enabling stateful computation on Bitcoin without consensus changes. Levy also co-authored BIP-360, the quantum-resistant address proposal that was merged into Bitcoin’s official BIP repository in February — a proposal that, unlike QSB, would require a softfork.

“StarkWare has some of the best hackers on the planet,” Eric Wall, co-founder of Taproot Wizards and board member of the Starknet Foundation, wrote on X. “It is beautiful to see when hackers use their powers for good.”

QSB builds on Binohash, a transaction introspection technique developed by BitVM creator Robin Linus of ZeroSync and Stanford University that was demonstrated on Bitcoin mainnet in February.

No Softfork Required

The no-softfork distinction is what sets QSB apart. Most paths to hardening Bitcoin against quantum attacks, including BIP-360 and hash-based signature schemes like SPHINCS+, require protocol-level changes that must navigate Bitcoin’s notoriously slow and contentious governance process.

That governance bottleneck is increasingly seen as the real vulnerability. A Google Quantum AI paper published March 30 concluded that breaking Bitcoin’s elliptic-curve cryptography could require fewer than 500,000 physical qubits — a roughly 20-fold reduction from prior estimates. The paper warned that a sufficiently advanced machine could derive a private key from an exposed public key in about nine minutes, narrowly inside Bitcoin’s 10-minute block window. Google itself has set a 2029 deadline to migrate its own authentication services to post-quantum cryptography.

QSB sidesteps the governance question entirely. The scheme operates within Bitcoin’s tightest legacy script constraints — 201 opcodes and a 10,000-byte script limit — and can be used by anyone willing to pay roughly $75 to $150 in cloud GPU compute and submit their transaction directly to a miner via a service like MARA’s Slipstream.

StarkWare has been at the center of Bitcoin’s quantum-defense efforts. Co-founder Eli Ben-Sasson has argued that Bitcoin must begin responding to the quantum threat now.

How It Works

Standard Bitcoin transactions use a digital signature scheme called ECDSA to prove ownership of funds. A quantum computer running Shor’s algorithm could reverse-engineer that signature process, deriving private keys from public keys and stealing coins.

QSB swaps out the security model. Instead of relying on the mathematical hardness of elliptic curves — which quantum computers can break — it relies on the hardness of reversing hash functions, which they cannot. The scheme forces a would-be spender to solve a computationally expensive hash puzzle that binds the transaction to a specific set of parameters. Any attempt to alter the transaction invalidates the puzzle solution, requiring the attacker to redo the work from scratch.

The result is roughly 118 bits of security against Shor’s algorithm, compared to effectively zero for standard Bitcoin transactions in a post-quantum world.

Early Stage

The project remains a work in progress. The GPU pinning search — the first of three phases required to construct a quantum-safe transaction — has been successfully tested, finding a valid result after roughly six hours across eight Nvidia RTX PRO 6000 GPUs. But the digest search and on-chain broadcast have not yet been completed end-to-end.

There are practical constraints as well. The transactions exceed default relay policy limits and must be submitted directly to miners. The locking script must be placed as a bare output because it exceeds P2SH’s 520-byte redeem script limit.

Still, the release demonstrates that a degree of quantum resistance is achievable on Bitcoin today — for anyone willing to bear the cost — without waiting for the community to agree on a softfork.

ETH Price Eyes $2.5K As Data Points To Undervalued Conditions

ETH Price Eyes $2.5K As Data Points To Undervalued Conditions

Ether (ETH) may be on the path to retesting $2,500 if the current rally above $2,150 and the bullish spot and futures market volumes pushing prices higher are sustained.

Ether is also supported by a key macro indicator that places the altcoin in a rare undervaluation zone not seen since 2022. The data points to fading selling pressure and the early stages of an accumulation process for Ether.

ETH price structure strengthens above $2,150

Ether’s daily chart shows bulls leading the charge after a 6.33% rally pushed the price above the $2,150 resistance. ETH now eyes a retest of its March highs near $2,385, with further upside toward the $2,475–$2,635 fair-value gap acting as a price magnet for bulls.

Repeat retests of $2,150 over the past two months suggest weakening resistance, as buyers continue stepping in at higher levels.

Charts show ETH market structure improving and the current volumes being largely spot market driven. On the four-hour chart, ETH maintains higher lows while attempting to break into the $2,250–$2,300 range.

The aggregated spot cumulative volume delta (CVD) has remained elevated in April at 184,500 ETH, reflecting sustained spot demand.

The futures CVD has also trended gradually upward to 4.36 million ETH, suggesting that derivatives traders are beginning to support, rather than lead, the move.

The funding rate remains positive at 0.0052, indicating a long bias, and the open interest near 4.75 million ETH is still range-bound, signaling limited leverage.

Data shows ETH is in a controlled accumulation phase, marginally led by spot demand, though a stronger breakout would likely require an expansion in futures positioning.

Macro index shows ETH in a “rare” undervalued zone

Ether may be nearing a macro bottom according to the Capriole Macro Index Oscillator with a reading at -2.42. This puts Ether in a rare undervalued zone historically linked with capitulation and trend reversals.

The indicator tracks investment behavior, cycle positioning, and onchain data, with deeply negative values often signaling seller exhaustion.

Previous signals highlight the metric’s reliability. In June to July 2022, ETH bottomed near $1,000–$1,200 when the indicator fell to -2.2. In October to November 2023, a drop to -1 aligned with ETH’s price breaking out after a drop to $1,500.

In April 2025, another negative reading marked a local bottom near $1,500, setting the stage for a rally above $4,000.

The current setup mirrors prior capitulation phases. ETH has fallen from highs near $4,800 to $2,100, while the oscillator sits near cycle lows.

With ETH now in a rare undervalued zone, the downside risk appears limited relative to the upside potential. However, the confirmation would come with a reclaim of the $2,400–$2,500 level and a move back toward zero for the macro indicator.

Analyst crypto sunmoon noted that the ETH taker buy/sell ratio has been trending upward for four to five months.

Combined with the current drawdown, the structure resembles the setup preceding the April to May 2025 rally, suggesting a similar recovery phase may be forming.
