BlackRock has updated its registration statement for the iShares Bitcoin Trust (IBIT), highlighting potential risks posed by quantum computing to Bitcoin's cryptographic security. The May 9 filing underscores theoretical vulnerabilities in Bitcoin's framework if quantum technology advances significantly.
Quantum Computing Risks to Bitcoin Security
BlackRock's filing warns that future quantum computing breakthroughs could compromise Bitcoin's encryption algorithms, enabling unauthorized access to wallets holding the trust's Bitcoin. While quantum capabilities remain uncertain, the firm emphasizes disclosing all potential threats—no matter how remote—as standard practice for ETF issuers.
Key concerns addressed:
- Cryptographic obsolescence from quantum advancements
- Wallet security vulnerabilities
- Regulatory, energy, and mining risks (e.g., China’s mining concentration, network forks)
Bloomberg ETF analyst James Seyffart clarified that such disclosures are routine:
"These are basic risk disclosures... It’s completely standard and makes complete sense."
Despite warnings, IBIT leads the spot Bitcoin ETF market with 19 consecutive days of inflows—totaling over $5.1 billion during the reporting period.
Ethereum ETF Updates: In-Kind Redemption Model
BlackRock also amended its spot Ethereum ETF filing to propose in-kind creation/redemption, allowing direct swaps of ETF shares for Ethereum. Benefits include:
- Lower transaction costs
- Reduced market friction
- Avoidance of crypto-to-fiat conversions
Analysts anticipate SEC approval for this model in 2025. Seyffart noted:
"We expect SEC approval for in-kind at some point this year... The final deadline is around October 2025."
