Can we still trust Ledger?

2 years ago

Self-custody is important successful crypto, and information is indispensable to self-custody. Ledger, a notable hardware wallet manufacturer, has built its estimation connected the unafraid retention of users’ backstage keys. Hardware wallets make a unafraid offline situation for storing keys and utilizing keys to execute transactions.

The user’s backstage keys are generated and stored wrong the instrumentality and are expected to ne'er permission it. This “cold storage” provides an unrivaled level of information compared with “hot wallets” oregon online wallets. The occupation is that tons of radical suffer their keys.

Ledger rolled retired a effect operation backup merchandise this week called Ledger Recover. If you springiness the institution your ID and idiosyncratic information, you tin wage for a work that takes your effect operation wrong your device, encrypts it into 3 “shards” and past shares them with assorted custodians.

Introducing a 3rd enactment inherently centralizes control, creating a azygous constituent of nonaccomplishment that could beryllium exploited by hackers oregon beryllium taxable to regulatory actions.

I don’t begrudge Ledger its effort to turn arsenic a concern to scope non-OG and non-cypherpunk-ethos users. Millions of normies, similar our skeptical babe boomer in-laws, volition lone ever beryllium onboarded to crypto done this benignant of custodial backup approach. Its mistake whitethorn person been successful trying to usage the aforesaid merchandise to entreaty to some crypto self-custody OGs and the broader aboriginal lawsuit normies.

Ledger’s rollout of its backup merchandise met with immoderate beardown reactions among its assemblage of customers. Many were amazed to larn that Ledger has ever had the capableness to interaction your concealed cardinal with its hardware updates. Many of america presumption our hardware devices arsenic sacrosanct. I intelligibly wasn’t knowledgeable capable astir this instrumentality that I spot to support my crypto assets.

Yesterday I freaked retired astir the revelation that @Ledger could spit retired your backstage cardinal with a firmware update.

Yet I noticed the smartest radical were not freaking out. Was I missing something?

I spent the evening educating myself, and present I'm successful the "nvm it's fine" camp.

Haseeb Qureshi chimed successful that portion helium besides reacted negatively astatine first, helium realized that this was ever existent astir Ledger. We’ve ever trusted it not to insert malware successful its firmware updates to bargain our effect phrases. He’s not wrong, but I wouldn’t accidental that’s a comforting thought.

In the end, thing atrocious tin hap connected your hardware instrumentality unless you motion a transaction. You clasp the power. I don’t cognize astir you, but I’m not a coder — I can’t archer a malicious update from a morganatic one, truthful I’m trusting Ledger connected that too. And I don’t precisely person the enactment not to o.k. the latest firmware update that includes Ledger Recover capability, arsenic Ledger warns that nonaccomplishment to update your firmware is simply a information risk.

They bash a crap occupation of providing spot successful the bundle stack though. A amended plan would incorporated functionality similar certificate transparency oregon cardinal transparency, truthful you wouldn't person to anticipation they don't unaccountably nonstop you a buggy firmware

I bash spot Ledger — it’s a large company. It has been the linchpin successful the exertion stack for crypto self-custody, astatine slightest successful my ain crypto journey.

But the extremity of a crypto self-custody instrumentality should beryllium to minimize spot requirements. And that could beryllium improved astatine Ledger done open-sourcing much of its bundle and hardware. Ledger’s main exertion serviceman was asked astir this connected May 17’s Bankless podcast and responded that Ledger has signed nondisclosure agreements that preclude it from doing truthful and argued that radical are improbable to crowdsource information audits anyway.

I’ll stake information researchers similar Andrew Miller, who uncovered vulnerabilities successful the Secret Network, would instrumentality up that task.

While Ledger’s communications regarding the rollout person been a disaster, its situation communications person been enlightening. I person surely realized I had an insufficient knowing of however hardware wallets work. But “Sorry, we can’t open-source thing due to the fact that of NDAs” is an insufficient reply to those successful the assemblage who person concerns that Ledger Recover could beryllium utilized by a malicious histrion to instrumentality users with a fake update and bargain their effect phrase.

Ledger could besides springiness maine the enactment to proceed to update my firmware without adding the Ledger Recover codification to my device. But successful the lack of open-sourcing its firmware, it won’t bash much, arsenic we won’t person immoderate mode to verify its claims.

This could beryllium a branding triumph if Ledger pivoted to rotation retired a “cypherpunk”-branded magnitude to its hardware and bundle that appeases the OG crypto assemblage specified that they mightiness beryllium consenting to opt into it, and lets existing hardware owners opt into it for their antecedently purchased hardware specified that caller updates are cypherpunk-branded and -approved, arsenic unfastened root arsenic possible, with crowdsourced information audits — the full package. All would beryllium forgiven.

For now, it doesn’t look Ledger plans to bash that. So, the options are to usage open-source hardware wallets, but those bash not person Ledger’s wide-ranging interoperability with emerging blockchains. Or you could physique your own, oregon conscionable usage the caller refurbished Gameboy unfastened root hardware wallet.

For now, and for galore coins, the safest enactment is astir apt to spot Ledger portion staying unfastened to competing developers of open-source hardware wallets.
