Ethereum researchers have warned that artificial intelligence could break the cryptographic signatures securing Bitcoin and Ethereum wallets in months, not years, in the worst-case scenario. The warning was filed 10 October 2026.[^1]

Separate analysis published 9 October 2026, citing Glassnode data, notes that cryptographic signature compromise by AI or quantum systems may threaten more than 31% of the Bitcoin supply.[^2]

There is no stated link between the two published assessments.

## What this stands on

1. Ethereum researchers warned that artificial intelligence could break the cryptographic signatures securing Bitcoin and Ethereum wallets in months, not years, in the worst-case scenario. ([u.today](https://u.today/almost-like-satoshi-knew-something-adam-back-throws-shade-at-ethereum), News)
2. According to Glassnode, the possibility of AI models or quantum computers breaking cryptographic signatures may threaten more than 31% of the Bitcoin supply.

A signature proves who filed this and that it has not changed since. It never makes a claim true.
