Hints of progress: State of Crypto

CoinDesk is hosting its second annual Consensus Hong Kong conference, and as always, we’ll have a number of policy-focused sessions. Are you in town? Find me on stage or around the show floor and say hi!

The narrative

CoinDesk’s annual Consensus Hong Kong conference will kick off this Wednesday with a speech from Hong Kong Chief Executive John KC Lee.

Why it matters

Hong Kong is playing an interesting role in the intersection of financial services between the global East and West. CoinDesk will be exploring that role at Consensus,

Breaking it down

We’ll be hearing from Financial Secretary Paul Chan and Securities and Futures Commission Chief Executive Julia Leung on day one of Consensus, and having conversations around the growth of real-world asset tokenization, stablecoins and evolving payment systems and how exchange-traded funds (ETFs).

Our speakers will include regulators and politicians from around the world, with panels looking at how both regulators and industry participants alike approach the sector — a conversation we’ve had every year at Consensus, but one that continues to evolve.

Privacy, artificial intelligence, decentralized finance and trading behaviors will also take one of the many stages throughout the conference.

It’ll be part of a busy week ahead: SEC Chair Paul Atkins will be testifying before the House Financial Services and Senate Banking Committees. Though the hearings are focused on SEC oversight generally, expect crypto and Atkins’ efforts to develop rulemakings around the sector to come up.

  • 01:30 UTC (9:30 a.m. HKT) Day 1 of Consensus Hong Kong kicks off.
  • 15:00 UTC (10:00 a.m. ET) The House Financial Services Committee is holding an oversight hearing with Securities and Exchange Commission Chair Paul Atkins.

Thursday

  • 02:00 UTC (10:00 a.m. HKT) Day 2 of Consensus Hong Kong kicks off.
  • 15:00 UTC (10:00 a.m. ET) The Senate Banking Committee is holding an oversight hearing with Securities and Exchange Commission Chair Paul Atkins.

Quantum Computers Need Millions More Qubits to Break Bitcoin, CoinShares Reports

Published

on

Existing encryption types - pre and post quantum

TLDR:

  • Breaking Bitcoin encryption requires quantum computers 100,000 times more powerful than today’s technology
  • Only 10,200 BTC in legacy addresses could cause market disruption if suddenly compromised by quantum attack
  • Cryptographically relevant quantum computers unlikely to emerge before 2030s, according to CoinShares analysis
  • Bitcoin can adopt post-quantum signatures through soft forks while maintaining defensive adaptability

 

Quantum computing poses no immediate threat to Bitcoin’s security infrastructure, according to digital asset manager CoinShares.

The firm’s latest analysis dismisses concerns about near-term vulnerabilities in the cryptocurrency’s cryptographic foundation.

Current quantum technology remains decades away from breaking Bitcoin’s encryption protocols. CoinShares estimates only 1.7 million BTC faces potential exposure, representing 8% of total supply.

The research suggests institutional investors should view quantum risks as manageable engineering considerations rather than existential crises.

Technology Requires Decades Before Becoming Cryptographically Relevant

CoinShares’ analysis reveals breaking Bitcoin’s secp256k1 encryption demands quantum systems with millions of logical qubits.

Current quantum computers operate at approximately 105 qubits, falling dramatically short of required thresholds.

Researchers estimate attackers would need machines 100,000 times more powerful than today’s largest quantum systems.

Reversing a public key within one day requires 13 million physical qubits and fault tolerance levels not yet achieved.

Breaking encryption within one hour would demand quantum computers 3 million times more advanced than current capabilities.

Each additional qubit makes maintaining system coherence exponentially more difficult, according to technical experts.

Cybersecurity firm Ledger’s Chief Technology Officer Charles Guillemet provided expert perspective on the technical challenges facing quantum development.

Speaking to CoinShares, Guillemet emphasized the massive scale required for cryptographic attacks. “To break current asymmetric cryptography, one would need something in the order of millions of qubits. Willow, Google’s current computer, is 105 qubits. And as soon as you add one more qubit, it becomes exponentially more difficult to maintain the coherence system,” Guillemet confirmed.

CoinShares projects cryptographically relevant quantum computers may not emerge until the 2030s or beyond. Long-term attacks on vulnerable addresses could take years to complete even after technology matures.

Short-term mempool attacks would require computations finishing in under 10 minutes, remaining infeasible for decades ahead.

Limited Vulnerability Concentrates in Legacy Address Formats

The digital asset manager’s research identifies exposure primarily in legacy Pay-to-Public-Key addresses holding roughly 1.6 million BTC.

Modern address formats including Pay-to-Public-Key-Hash and Pay-to-Script-Hash conceal public keys behind cryptographic hashes. These contemporary formats maintain security until owners actively spend their funds.

CoinShares determined only 10,200 BTC sit in outputs potentially causing market disruption if compromised suddenly.

Distribution and amount of quantum vulnerable coins

The remaining vulnerable coins distribute across 32,607 individual outputs of approximately 50 BTC each. Breaking into these addresses would require millennia even under optimistic quantum advancement scenarios.

Bitcoin’s security framework relies on elliptic curve algorithms for authorization and SHA-256 hashing for protection.

Quantum algorithms cannot alter Bitcoin’s fixed 21 million supply cap or bypass proof-of-work validation requirements.

Grover’s algorithm reduces SHA-256 security effectively but brute-force attacks remain computationally impractical.

Renowned cryptographer Dr. Adam Back addressed Bitcoin’s capacity for defensive evolution in response to future quantum threats.

The Blockstream CEO and Bitcoin contributor explained the network’s adaptability to CoinShares. “Bitcoin can adopt post-quantum signatures. Schnorr signatures paved the way for more upgrades, and Bitcoin can continue evolving defensively,” Back told CoinShares.

Users retain sufficient time to migrate funds voluntarily to quantum-resistant addresses. Market impact appears minimal, with vulnerable coins likely resembling routine transactions rather than systemic shocks.

Are Non-Financial Use Cases in Blockchain Dead?

Published

on

Decentralization, Social Media, Web3, Web3 Decentralization Initiatives

Prominent crypto venture capitalists are clashing online about whether non-financial use cases in crypto, Web3, and blockchain have failed due to a lack of investor demand and product-market fit or if the best days for non-financial applications still lay ahead.

The debate started on Friday when Chris Dixon, a managing partner at venture capital firm a16z crypto, published an article arguing that years of “scams, extractive behavior and regulatory attacks” were the reason that non-financial use cases in crypto have not taken off.

These use cases include decentralized social media, digital identity management, decentralized media streaming platforms, digital rights platforms, Web3 video games and more.

“Non-financial use cases for crypto have failed because no one wants them,” Haseeb Quereshi, a managing partner at crypto venture firm Dragonfly, said in a response on Sunday. He added:

“Let’s just admit it. They were bad products. They failed the market test. It was not Gensler or Sam Bankman-Fried (SBF) or Terra that caused these things to fail; it was that no one wanted any of it. Pretending otherwise is coping.”

Dixon said that as a16z crypto’s funds are managed with at least a 10-year time horizon, “building new industries takes time.”

“You don’t have the luxury of ‘waiting to be right’ in VC,” Nic Carter, the founding partner of venture firm Castle Island Ventures, said in a reply to Quereshi. “You need to be right about a market during the 2-3 year fund deployment period,” he said. 

The debate follows a surge of VC investment into crypto projects in 2025, which mostly flowed to tokenized real-world assets (RWAs), physical or traditional financial assets represented onchain by digital tokens.

Different approaches to portfolio building

Dragonfly’s portfolio is built around financial use cases and blockchain infrastructure that helps move value and risk through the onchain financial system.

Some of the firm’s investments include the Agora stablecoin and payments platform, payments infrastructure provider Rain, synthetic dollar issuer Ethena, and the Monad layer-1 blockchain network.
