Bitcoin Devs Float Proposal to Freeze Quantum-Vulnerable Addresses — Even Satoshi Nakamoto’s

Published

on

A new Bitcoin draft proposal wants to do what’s long been unthinkable: Freeze coins secured by legacy cryptography — including those in Satoshi Nakamoto’s wallets — before quantum computers can crack them.

That’s according to a new draft proposal co-authored by Jameson Lopp and other crypto security researchers, which introduces a phased soft fork that turns quantum migration into a ticking clock. Fail to upgrade, and your coins become unspendable.

That includes the roughly 1.1 million BTC tied to early pay-to-pubkey addresses, like those of Satoshi’s and other early miners.

“This proposal is radically different from any in Bitcoin’s history just as the threat posed by quantum computing is radically different from any other threat in Bitcoin’s history,” the authors explained as a motivation for the proposal. “Never before has Bitcoin faced an existential threat to its cryptographic primitives.”

“A successful quantum attack on Bitcoin would result in significant economic disruption and damage across the entire ecosystem. Beyond its impact on price, the ability of miners to provide network security may be significantly impacted,” they added.

The draft BIP outlined three phases:

Phase A: Banning sending funds to legacy ECDSA/Schnorr addresses, nudging users toward quantum-resistant formats like P2QRH. (Starts 3 years after BIP-360 implementation)

Phase B: Make all legacy signatures invalid at the consensus layer. Coins in quantum-vulnerable addresses become permanently frozen. (Kicks in 2 years after Phase A)

Phase C (optional): Introduce a recovery path for stuck coins using zero-knowledge proof of BIP-39 seed possession. This could be a hard or soft fork.

But Why Now?

Bitcoin’s cryptography has never faced an existential threat and still doesn’t, except pre-emptive ones that can possibly target early wallets. Researchers say quantum computers capable of breaking ECDSA may arrive as soon as 2027.

A May report by CoinDesk flagged a new study suggesting that breaking RSA encryption with quantum computers may require 20 times fewer resources than previously thought.

Although Bitcoin uses elliptic curve cryptography, it remains vulnerable to quantum attacks similar to those threatening RSA. Current quantum computers are not yet capable of breaking these encryption methods, but research is rapidly advancing.

Earlier in July, eight legacy Bitcoin wallets moved over $8.5 billion worth of ‘Satoshi-era’ bitcoin after 15 years of dormancy — sparking speculation, among some, about moving to wallets with improved security as

That’s the red line for Lopp and the team.

Around 25% of all bitcoin have exposed their public keys, meaning they’re vulnerable to a “Q-day” style attack. If attackers are patient, they could use quantum tools to quietly drain dormant wallets over time without tripping alarms.

“Quantum attackers could compute the private key for known public keys then transfer all funds weeks or months later, in a covert bleed to not alert chain watchers,” the draft proposal stated. “Q-Day may be only known much later if the attack withholds broadcasting transactions in order to postpone revealing their capabilities.”

The proposal is still in draft stage and has no BIP number yet. And it may be the only way Bitcoin survives a quantum future.

ECLIPSE TOKEN GENERATION EVENT: Eclipse, the layer-2 that combines technology from the Ethereum and Solana blockchains, shared that it has gone live with an airdorp of its $ES token. The team behind the network shared that the initial distribution will occur over the next 30 days, and a total of 1 billion $ES tokens have been minted, with distribution structured to go to community incentives and long-term protocol sustainability. Of the supply, 15% is allocated to an airdrop and liquidity provisions for core community members and developers who have supported the network from the start. 35% will support ecosystem growth and research and development, aimed to help scale the network. Contributors will receive 19% of the supply, including team members, with a four year vesting period and three year lockup schedule. The remaining 31% is for early supporters and investors, who are subject to a three year lockup schedule to commit to Eclipse’s roadmap long-term. — Margaux Nijkerk Read more.

RISC-ZERO “BOUNDLESS” INCENTIVIZED TESTNET GOES LIVE : Boundless, the decentralized zero-knowledge (ZK) compute marketplace powered by RISC Zero, has launched its incentivized testnet (which it is calling “Mainnet Beta”) on Base, Coinbase’s Ethereum layer-2 network. With Boundless’ incentivized testnet, developers can build and test applications in an environment as if the protocol is in fully live format. The network has already landed early support from industry heavyweights like the Ethereum Foundation, Wormhole and EigenLayer. A decentralized marketplace for zero-knowledge compute connects those who need zero-knowledge proofs — such as developers building rollups, bridges, or privacy-preserving applications — with a distributed network of independent “ZK provers or miners” who generate and verify those proofs. Instead of relying on centralized parties, this model allows anyone with the right hardware to contribute computing power and be rewarded for doing that cryptographic work. — Margaux Nijkerk Read more.

THE FIRST DEPIN POWERED CREDIT CARD: Aethir, a decentralized GPU cloud network, has teamed up with Credible Finance, a lending protocol, to introduce what they call the first credit card and loan product powered by a decentralized physical infrastructure network (DePIN). The move is designed to give Aethir’s native ATH token holders and node operators access to stablecoin credit without liquidating their tokens — a step toward blending on-chain infrastructure with real-world financial capital. The product, which debuted on Wednesday, lets eligible users collateralize their ATH tokens to access a revolving credit line or preload a no-fee card with ATH or stablecoins on Solana. Loan approvals and limits are determined by Credible’s AI-driven credit engine, which evaluates a user’s on-chain activity, asset holdings and transaction history. — Margaux Nijkerk Read more.

Regulatory and Policy

  • The House of Representatives on Tuesday did not vote on a procedural motion to advance a trio of crypto bills, but may vote Wednesday to advance the legislation. As it sped into its crypto-focused week on Tuesday, the U.S. House’s process toward passing digital assets bills ground to a sudden halt over a procedural vote as members of the House Freedom Caucus objected to the way some of the legislation has developed under Senate dominance. The legislation still has strong, bipartisan support, suggesting the procedural mishap may be overcome as a further vote was scheduled for later Tuesday afternoon. This vote was canceled less than 15 minutes before it was set to begin, so the matter may not be raised again until early Wednesday — the same day the Digital Asset Markets Clarity Act was set to be voted on. — Jesse Hamilton, Stephen Alpher, & Nikilesh De Read more.
  • A 12-person jury has been seated for Tornado Cash developer Roman Storm’s criminal trial, and opening arguments are set to begin later this afternoon in the Thurgood Marshall courthouse in Lower Manhattan. Seven women and five men with a diverse range of backgrounds and ages will decide whether the U.S. Department of Justice can prove beyond a reasonable doubt that Storm engaged in conspiracy to commit money laundering, conspiracy to violate U.S. sanctions and conspiracy to operate an unlicensed money transmitting business. — Cheyenne Ligon & Nikilesh De Read more.

ICP Climbs With Broader Crypto Rally, Holds Gains Above $5.50

Published

on

By

Internet Computer (ICP) moved higher in tandem with a broad-based crypto market surge, climbing 1.89% $5.5354 after peaking at around $5.65 early on Wednesday. As capital rotated into altcoins following gains in bitcoin and ether, ICP followed suit with a 7% upswing, driven by early bullish momentum and strong support at the lower end of its range.

The 24-hour window spanning July 15 at 15:00 UTC to July 16 at 14:00 UTC saw ICP fluctuate within a $0.39 range. Volume during this rally exceeded 964,000 units, indicating robust participation from both large and small buyers as the altcoin sector gained steam.

After peaking, ICP transitioned into a sideways consolidation phase between $5.50 and $5.58. Two failed attempts to break above the $5.64–$5.66 resistance zone confirmed short-term exhaustion, according to CoinDesk Research’s technical analysis data model. The token remained well bid near $5.52, where fresh demand consistently emerged.

This consolidation reflects similar dynamics seen across Layer 1 tokens, which are seeing profit-taking after multi-session gains but maintaining higher support zones. ICP’s ability to hold steady in a tightening range mirrors the broader market’s pause after a strong leg up.

If bullish sentiment across the crypto market continues, ICP may challenge the $5.60–$5.66 resistance band again, supported by steady inflows and its strong positioning in the decentralized computing narrative.

Technical Analysis Highlights

  • ICP climbed 7% from $5.28 to $5.66 before consolidating in a $0.39 range.
  • Early rally supported by 964K+ volume, matching broader altcoin strength.
  • Resistance firmed at $5.64–$5.66 with two rejection attempts.
  • Price stabilized in a $5.50–$5.58 channel for much of the session.
  • Support formed around $5.52; buyers consistently defended this level.
  • ICP rebounded from $5.50 to $5.53 in the final hour on 19.8K+ volume.
  • Market structure remains bullish above $5.50 amid macro crypto strength.
  • Current price: $5.5354, up 1.89% on the day.
