Key Takeaways
- • Ledger CTO Charles Guillemet highlighted two recent cryptographic developments that could pose future risks to Bitcoin's security.
- • A new subexponential algorithm may solve elliptic-curve cryptography problems more efficiently, but it currently poses no immediate threat to the curves Bitcoin widely uses.
- • A significant improvement in quantum computing attacks reduces the estimated resources needed to break Bitcoin's cryptography, though such quantum computers do not yet exist.
- • Per Pluang's listing as of Oct 31, 2026, Bitcoin traded at Rp1.392.721.242, down 3.58% over the prior day, with roughly 20.1 million of its 21 million maximum supply in circulation.
- • Pluang users showed a balanced stance, with 58% buying and 42% selling, and an average holding period of 112 days.
Summary
Ledger CTO Charles Guillemet has pointed to two recent cryptographic advances that could create security risks for Bitcoin over the longer term, according to the original report. The first is a new subexponential algorithm that may theoretically solve elliptic-curve cryptography problems more efficiently than previous methods. The report stresses that the algorithm currently poses no immediate threat to the elliptic curves Bitcoin widely uses.
The second development is a significant improvement in quantum computing attacks. It reduces the estimated resources required to break Bitcoin's cryptography. Guillemet's warning carries the caveat that the quantum computers needed for such an attack do not yet exist. Taken together, the findings underscore the need to monitor and evolve cryptographic protections for cryptocurrencies, the report said.
The warning comes as Bitcoin trades on Pluang at Rp1.392.721.242, down 3.58% over the prior day as of Oct 31, 2026 at 04:21 WIB. Bitcoin's circulating supply is near its cap, at 20.1 million of 21 million BTC. Despite the security concerns, Pluang's user base was roughly balanced, with 58% buying and 42% selling, and users held their positions for an average of 112 days.
