Asked @Grok if @Ledger devices/hardware use(s) a True Random Number Generator to generate seed phrases:
Yes, Ledger hardware wallets (Nano S/S Plus/X, Stax, Flex, and newer models) generate seed phrases using a certified True Random Number Generator (TRNG) inside the Secure Element chip. https://t.co/A9bWIGi6XE
How it works
• During initial setup, the device draws full 256 bits of entropy directly from the hardware TRNG in the Secure Element.
• This raw entropy is processed (with post-processing/whitening) and converted on-device into a standard BIP-39 24-word Secret Recovery Phrase.
• Private keys are derived from that seed and never leave the Secure Element. https://t.co/oW5NScf9ne
Certifications and quality
The TRNG is independently evaluated by third-party laboratories under the AIS-31 standard (typically Class PTG.2) and forms part of the Secure Element’s Common Criteria certification (EAL5+ or EAL6+ depending on the chip/model).
These evaluations include:
• Mathematical modeling of the physical noise source (e.g., oscillator jitter / thermal noise)
• Extensive statistical testing under varying conditions (temperature, voltage, frequency)
• Built-in detection of defects or attacks that could bias the output https://t.co/YcxG1aKD3X
Ledger’s own documentation and threat model treat high-quality, unpredictable seed generation as a core security requirement, and the company has publicly confirmed that all current devices use this certified hardware TRNG path. https://t.co/IckEffCEnr
Context vs. other wallets
In the recent Coldcard firmware issue (where a 2021 code path fell back to a weak software RNG, reducing effective entropy), Ledger stated its devices were unaffected precisely because of the certified Secure Element TRNG. No equivalent widespread low-entropy seed-generation failure has been reported for Ledger devices. @thorbjornkonig
Caveats (as with any hardware wallet):
• Early firmware on the original Nano S had theoretical physical-access issues related to RNG control that were later patched; modern devices include stronger protections and attestation.
• The TRNG itself is a physical process, so absolute “true randomness” is defined by the strength of the entropy source + certification rather than pure mathematical perfection. Independent labs rate the AIS-31 implementations highly for cryptographic use.
• Security also depends on supply-chain integrity, firmware authenticity (Ledger’s genuine-check process), and user practices (passphrase, backups, etc.).
In short, by design and certification, Ledger devices rely on hardware true randomness for seed generation rather than software or host-provided entropy.
Great explainer by Wietse how the XRP Ledger wallet Xaman sources true randomness, by using iOS and Android native randomness generator that uses your own device hardware noise.
Also reminder to ignore the marketing, air gapped/hardware etc, and focus on the right questions.
Self custody is worth nothing if what you're self custody (your keys) are not generated truly random with large entropy.
Simple: XX athletes should have a level playing field. XY in XX sports is NOT a level playing field. Verbal 🤮 of virtue signaling lacks any reason, sense or merit and completely disregards the discipline and dedication an XX athlete has to her sport. XX athletes need organizations who value them, their wellbeing and will be their fiduciaries rather than the fiduciaries to a cabal/agenda/ideology.
Susan “fighting” is pointless but her providing educational insight into the machinery of the reality of the racketeering networks built on extraction and feeding the forever war machine is spot on. The Matrix is being rewired. Disintermediation and a level playing field where “building” is the cornerstone to prosperity is evolving. No gatekeepers. Call it “The American System,” that’s fine but it is the level playing field where creativity and innovation will be rewarded without chokepoints or gateways guarded by gate keepers who have built empires demanding fees from participants who call friction “business”. Those days are coming to a close.
@elonmusk@yoyonofukuoka@paulg The expiration day is the 85th Anniversary of the 🇯🇵 Japanese “Surprise” Attack at Pearl Harbor, December 7, 2026. And what’s happening with the 💴 at the moment? Coincidence?
