Solana users need no “bunker mode” amid quantum security concerns, Creech says

Solana users do not need to put their wallets or keys into “bunker mode” against quantum computing threats, according to the Solana Foundation’s VP of Technology, Jacob Creech. His reassurance on Solana’s quantum security comes alongside plans for stronger signature schemes, with a working proof of concept already in place.

Key takeaways

• Jacob Creech says Solana users need no “bunker mode” protection.
• The secret seed stays protected even if derived keys are exposed.
• Planned upgrades include seed verification and stronger signatures.

Coinfomania reported on October 8, 2026, that Creech’s statement addressed growing concerns about quantum computing’s impact on blockchain cryptography. The report described Solana’s existing Ed25519 cryptography as secure despite those concerns.

Solana’s quantum security reassurance

Jacob Creech reassured users that they do not need enhanced “bunker mode” protection for their wallets or keys at this time. The Foundation’s position pairs confidence in current security with a defined path toward future network upgrades.

The technical distinction centers on the secret seed. Creech said that breaking Solana’s Ed25519 cryptography could expose derived keys, while the underlying seed would remain protected. His explanation separates potential exposure of those keys from exposure of the seed itself.

Seed verification and stronger signatures

Planned Solana network upgrades would allow users to verify their knowledge of the seed and transition to more secure signature schemes. These are the two security changes described in the Foundation’s path forward.

A working proof of concept for the upgrades already exists, the report said. The proposed changes extend Solana’s quantum security preparations beyond reassurance about its current cryptography to a planned transition toward stronger signatures.

Price stability and user confidence

Solana showed no significant price movement over the 24-hour period covered by the report.

The report suggested that addressing quantum threats could support user confidence and broader adoption. It linked those potential benefits to the effectiveness of the planned security upgrades; the reported market result was unchanged, with no significant movement during that period.
