A Developer Just Built Quantum-Safe Bitcoin Without Changing a Single Line of the Protocol: Is This the Fix BTC?

Published

Researcher Avihu Levy published a working implementation of Quantum Safe Bitcoin on April 9, 2026 – no protocol change required.

The scheme operates entirely within Bitcoin’s existing script constraints, making it available to any user willing to absorb the compute cost today.

Bitcoin’s governance culture makes a Bitcoin soft fork extraordinarily difficult to coordinate. BIP-360, which Levy co-authored and which was merged into Bitcoin’s official repository in February 2026, laid out a quantum-resistant address standard, but it requires protocol-level consensus that could take years to materialize.

Quantum Safe Bitcoin sidesteps that bottleneck entirely. It’s not a theoretical workaround; Levy shipped GPU-accelerated CUDA code, Python pipelines, and complete Bitcoin scripts alongside the academic paper.

How QSB Actually Works – Hash Puzzles, Not Elliptic Curves

Standard Bitcoin transactions rely on ECDSA signatures over the secp256k1 curve. Shor’s algorithm can compute discrete logarithms efficiently, meaning a sufficiently powerful quantum computer could forge those signatures and drain any wallet with an exposed public key.

Post-quantum cryptography addresses this – but every known implementation requires larger signatures and new opcodes, which means a soft fork.

Levy’s approach cuts the elliptic curve dependency at the root. The scheme, built on Binohash (Robin Linus, 2026), replaces the standard signature verification with a hash-to-signature puzzle. The Bitcoin script hashes a transaction-bound public key via OP_RIPEMD160 and interprets the resulting 20-byte output as a DER-encoded ECDSA signature.

A random 20-byte string satisfies DER structural constraints with probability roughly 2−46 – that’s approximately one in 70 trillion attempts – which defines the proof-of-work target.

The critical distinction: this puzzle’s security rests entirely on RIPEMD-160’s preimage resistance, not on any elliptic curve assumption.

Shor’s algorithm attacks discrete logarithms. It does not break hash functions. That single architectural decision is what makes Quantum-Safe Bitcoin resistant to the quantum threat without touching the protocol.

The construction works in three phases. First, transaction pinning: the prover searches over (sequence, locktime) parameter pairs until the recovered public key’s RIPEMD-160 hash produces a valid DER signature – approximately 246 work.

Second, two digest rounds: for the pinned transaction, the prover searches over subsets of dummy signatures; each subset alters the scriptCode via FindAndDelete, producing a different sighash and a different recovered key.

Find a subset whose recovered key hashes to a valid DER signature (~246 candidates per round). The total computational cost is $75–$150 per transaction on cloud GPUs.

Zero-Knowledge Proofs and Dashlink enter the picture as an efficiency layer for proof verification. The QSB construction leverages post-quantum cryptography principles by anchoring security to hash-based assumptions – the same foundation underpinning ZK-friendly hash functions used in modern Zero-Knowledge Proofs.

Dashlink’s role is to compress the verification burden so that proof validation stays within Bitcoin’s existing 10,000-byte script limit and 201-opcode ceiling. No new opcodes. No consensus change. The scheme is consensus-valid under rules Bitcoin already enforces.

Bitcoin Hyper Targets Early Mover Upside

Bitcoin Hyper (HYPER) is currently in presale, targeting early-mover upside in the Bitcoin yield infrastructure layer – a sector drawing serious institutional attention as US spot Bitcoin ETFs pulled in $471.3 million in a single week.

The presale has raised $32 million to date, with the current token price at $0.0093 and staking APY running at 86% annualized for early participants.

The core technical differentiator: Bitcoin Hyper operates as a Bitcoin-native Layer 2 executing smart contracts with BTC as the settlement asset – bypassing the wrapped-token credit risk that plagues existing BTC DeFi infrastructure.

That’s a specific, verifiable architecture claim in a space full of vague interoperability promises.

Research Bitcoin Hyper here before the presale window closes.

Trump-Linked Crypto Tokens Face Renewed Scrutiny After Plummeting in Price

United States President Donald Trump is facing renewed scrutiny, as crypto tokens and projects promoted by the US president crash to all-time lows or sit near record low levels.

The Official Trump token (TRUMP), a memecoin promoted by Trump, hit an all-time low of about $2.73 in March 2026 and is currently trading at about $2.86, according to data from CoinGecko.

World Liberty Financial (WLFI), a decentralized finance (DeFi) platform co-founded by Trump’s sons, also issued a governance token, which crashed to an all-time low on Saturday, falling to just $0.07.

WLFI is down by nearly 75% from its all-time high of about $0.31 reached in September 2025, while the TRUMP memecoin is down by about 90% since its all-time high of over $73 reached in January 2025.

“We thought Sam Bankman-Fried or Gary Gensler were the worst things to happen to the crypto industry, and they were horrible,” Professor Tonya Evans said in response to the plummeting token prices. She added:

“But, turns out, it was the guy who surrounds himself with sycophants, siphons every bit of value he can for himself, and then expeditiously bankrupts companies and casinos without consequence.”

President Trump also announced another gala for token holders, scheduled to take place on April 25, fueling renewed scrutiny from US Democratic lawmakers, who have accused Trump of influence peddling by giving token holders access to him.

US lawmakers send letter to Trump memecoin creator

Senators Elizabeth Warren, Richard Blumenthal and Adam Schiff recently sent a letter to Bill Zanker, the individual who launched the Trump memecoin, requesting details on the purpose of the planned Trump memecoin gala in April.

The organizers of the event are “dangling access” to Trump, the lawmakers said, according to Politico, which obtained a copy of the letter. 

Trump and his family members stand to benefit from increased sales of the Trump memecoin; attendees are required to hold TRUMP tokens to gain access to the event, the Senators said.
