Bitkey wallet features random chips for security, Peter Todd notes

Bitkey wallet features random chips for security, Peter Todd notes
Bitkey uses unique chips for security

Peter Todd highlights a subtle security measure found in the Bitkey hardware wallet: random plastic chips are embedded into each unit, ensuring that every device is unique and making replacement attacks more difficult.

He also notes that a similar approach was previously seen in a special edition clear Coldcard wallet, which incorporated gold flakes in the plastic.

Todd has previously recommended that hardware wallets adopt the push button technique as a default security measure, with dice rolling as an advanced option, according to a past article. In a separate discussion, he outlined the need for true randomness in wallet software, adding that unpredictability alone does not guarantee protection against attacks, as detailed in a previous report. Todd’s ongoing commentary focuses on the importance of layered and verifiable defenses in cryptographic wallet design.
