Crypto Wallet Ledger To Lay Off 10% of Workforce Following Product Issues

The crypto bear market hasn’t been kind to many blockchain or crypto-focused businesses and companies, who have been forced to revisit their strategies, lay off employees, or even close up shop due to lack of funding or interest.
The latest victim of waning interest in the crypto sphere, is hardware wallet manufacturer Ledger, who is reportedly laying off as much as 10% of their workforce. But is the layoff due to the bear market, or have some business-related blunders caused the tech firm to falter?
Ledger Faces Workforce Reductions As Crypto Bear Market Fallout Continues
The crypto bear market of 2018-2019 has been long and brutal, resulting in even the largest crypto firms having to lay off employees, including Bitcoin mining manufacturing giant Bitmain and Ethereum startup incubator ConsenSys. However, the latest entity that is facing extensive layoffs, is France-based cryptocurrency hardware wallet manufacturer Ledger.
Related Reading | Bitcoin and Ethereum Trading Volume Reaches Crypto Bull Run Peak Levels 
According to a report from local French media outlet Presse Citron, the wallet maker behind the popular Ledger Nano S USB-device, is considering laying off as much as 10% of their 200 employees.
During the 2017 bull run, Ledger is said to have shipped and sold over one million units. While Ledger CEO Eric Larchevêque has told investors that recent sales of their hardware devices “are good,” clearly the company is facing some financial issues if a 10% reduction in workforce is being considered.
Bear Market Blues, Or Bad Business Moves?
Ledger’s woes may not entirely be the result of the crypto bear market. The firm has recently caused quite a stir in the crypto space, repeatedly disappointing its customers, and for calling out its closest competition in bad taste.
The issues began at the close of last year, when Ledger issued an update to its popular Nano S hardware wallet, that effectively limited the amount of apps that could be installed to just 2 or 3, according to Redditors voicing their distaste in the r/ledgerwallet subreddit. Redditors complained that the update made the Nano S obsolete, forcing users to consider upgrading to the Nano X or be stuck with a lesser experience than they had grown accustomed to.
There, additional complaints can be seen from crypto investors who pre-ordered the firm’s bluetooth-enabled hardware wallet, the Nano X, which was originally slated to begin shipping in March. Ledger experienced production quality issues that resulted in a sub-par batch of initial units, which Ledger was forced to reject, causing a delay.

Due to unexpected production issues at the last minute, we’re deeply sorry to tell you that the Ledger Nano X shipment will be delayed for at least 1 month.
We’re doing all we can to ship them as soon as possible and will keep you posted.

Ledger expects replacement units in late April, so the Nano X should begin shipping soon thereafter, barring any additional surprises in production.

Monero Fixes Bug After a User Claims to have Lost USD 80000

Bugs are pretty common in the software coding industry and so is with the projects in the blockchain world. But not all teams are able to patch things quickly. Well, that’s not the case with Monero team which has fixed a bug in the Ledger Monero code within quick time.
Monero says the number of wallets involved was minimal
In early march Ledger, Dev team had posted on warning on Monero’s (XMR) subreddit on March 4 advising users to avoid using the Nano S Monero app. Apparently, a bug associated with the app was discovered when a Redditor named MoneroDontCheeseMe posted a claim that he believes to “have just lost ~1680 Monero [around $80,000] due to a bug.” In the account, the user stated that after transferring about 0.000001 XMR from the Ledger to a view-only wallet, the user sent another 10, 200 and then 141.9 XMR.
According to the report, before sending the last transaction, MoneroDontCheeseMe had about 1,690 XMR in the wallet and 141.95 XMR in an unlocked balance, which is why he or she decided to send 141.9 XMR. Still, after the transaction, the user’s wallet is reportedly showing a balance of 0 XMR.
Furthermore, according to the Reddit user, the amounts sent and the transactions recorded on the blockchain did not line up. The user also mentioned that the 200 XMR transactions actually deducted 1691.001 XMR from the Ledger Wallet, and also that the amounts reported for the 10 XMR transactions are strange.

While things were pretty unclear, a post appeared on Monero’s Reddit page stating that all was now fixed and patched by developers luigi1111 and stoffu. According to the post
“A few weeks ago some Ledger Monero users got affected by a bug in the Ledger Monero code. Due to the bug, a handful of transactions were erroneously constructed and the wallet was not able to spot (and subsequently credit) the change, thereby letting the user believe their funds were lost. Fortunately, we were, in collaboration with the Ledger team, able to resolve this bug and recover the ‘lost’ funds of the affected users.”

The post further stated that only a minimal wallet was impacted. This helped the dev team of Ledger and Monero to collaborate and give out a solution quickly. Hope Monero will be able to keep itself out of such bugs in the future.
Will Monero’s dev team continue to solve such bugs and make it a top coin? Do let us know your views on the same.

Ledger Monero bug: ‘Lost’ funds of users affected by Ledger change output bug successfully recovered

On 8 April 2019, one of the moderators of the Monero sub-Reddit released a post-mortem of the Ledger bug that affected Monero users, resulting in them ‘losing’ their funds.
An announcement by Monero || #XMR on Twitter read,
“We have, in collaboration with the Ledger team, successfully managed to recover the ‘lost’ funds of the users affected by the Ledger change output bug”
The initial announcement regarding the bug was made in early March, 2019 by the Ledger team on Reddit. Even Kraken, a leading exchange in the US, released an official statement claiming that they would be suspending its funding services till this issue was fixed by the team.
The Ledger team had stated,
“In the last version of Monero client 0.14 with application 1.1.3, it seems there is a bug with the change address: The change seems to not be correctly sent.”
Udi Wertheimer, a coder, had stated that this bug would result in XMR users incurring a massive loss of funds if they tried to spend the money stored in their Ledger wallets. He also requested them to refrain from doing so.
Nevertheless, according to the post-mortem report, transactions were “erroneously constructed and the wallet was not able to spot [and subsequently credit] the change.” This was what led investors to assume that their funds were lost.
This issue was resolved by a collaboration between the Ledger and the Monero team, and the ‘lost’ funds have been recovered. The post-mortem further revealed the reason why Ledger wallets could not identify the change and credit the balance.

The post stated,

“The bug was investigated by Ledger and described to both luigi1111 and stoffu. Fortunately, luigi1111 designed a concept that would allow one to retrieve the lost funds. Subsequently, stoffu created the required manual patch. Lastly, the Ledger team assisted the affected users with retrieving their funds.”

The post further assured that from now on, pull requests pertaining to Ledger’s Monero code would be thoroughly checked and reviewed by the team, as a step towards avoiding similar bugs in the future.

Bitcoin Giant Doubles Down On Crypto Custody: Will It Spark Institutional Adoption?

With recent exchange imbroglios, like QuadrigaCX’s nine-figure mishap and DragonEx’s recent loss of purported millions worth of Bitcoin, Ethereum, and other crypto assets, big-name onlookers are likely shying away from the space.
Related Reading: DragonEx Crypto Exchange Hack Highlights the Importance of Using Reputable Platforms
More likely than not, they see investing in this embryonic asset class as entirely risky, and thus nonsensical. A recent scathing Bitcoin-centric feature from mainstream business news outlet The Economist would confirm this. The article’s author mentioned the QuadrigaCX fracas a number of times to bash cryptocurrencies, as have many other mainstream outlets. (An anecdotal aside: whenever my friends personally bring up cryptocurrencies, they now always mention QuadrigaCX).
Industry firms, like Ledger, are trying to fill in the gaps, however, with a newfangled partnership that could turn the security issue on its head.
Keeping Bitcoin Safe
According to a recent press release, Ledger has partnered with Legacy Trust, a Hong Kong-registered and -licensed public trust company, to provide institutions with a custodial offering for Bitcoin and other digital assets. The two firms are purportedly targeting over-the-counter (OTC) desks, crypto exchanges, and high net-worth individuals with this venture, as it looks to fill a gaping hole in the institutional onboarding process.

We are thrilled to work with Legacy Trust to introduce a world-first institutional grade digital asset custody solution by leveraging the Ledger Vault – a multi-authorization wallet management tool for digital assets.
Read more here: https://t.co/SHjjRUDZRh pic.twitter.com/iffB62VBRD
— Ledger (@Ledger) March 28, 2019

Ledger will provide its Vault product, a key management solution, and technical expertise, while Legacy Trust will harness its license and industry reputation to secure clients across the board. Legacy’s Vincent Chok elaborated:
“The combination of Ledger’s technological versatility in safekeeping digital assets with Legacy Trust’s regulatory standing provides a complete and permanent solution to the issue of custody in the digital asset space, that did not exist until now.”
The solution will purportedly be unique, in that Ledger and Legacy will allow for the customization, thus allowing its clients to alter the service as they please to fit their specific needs. For Bitcoin exchanges, for instance, a “warm” wallet system could be used, allowing for fewer requirements to be met for the issuance of a transaction. For long-term holders, a classical cold storage system can be set in place, making it extremely difficult for an attacker to withdraw funds with the explicit permission of a number of stakeholders.
Demetrios Skalkotos, the head of the Ledger Vault division, tells The Block that the product was “designed […] to be very flexible for a client’s needs.” And in the eyes of Pascal Gauthier, the president of Ledger, this might be the single offering that could propel the industry to new heights, as a mass of institutions rushes into the crypto market.
Why Crypto Custody Is Of Utmost Importance
In an exclusive interview with NewsBTC at Token2049, Gauthier explained that he is “100%” sure that custody is the primary facet of crypto holding back the so-called “institutional herd” right now. He likens the current custody subindustry to the American gold rush, but with no banks, vaults, and safe makers. Gauthier rhetorically asked: “You can have a lot of crypto, but where do you put it?” Right now, he claims, there are few viable answers to that question. Well until the recent launches of Vault, Fidelity, and similar ventures anyway. 
Pascal Gauthier
So as “Vault and similar products are up,” providing institutional players with “security, asset support, and otherwise,” big and smart money can finally flood into this ecosystem. However, he makes it clear that there won’t be an instant transition from an anti-institution environment to one that has enough infrastructure to accommodate Wall Street’s biggest names. Gauthier tells us that while institutional infrastructure has moved from a state of just proofs of concepts to actual product, it may take upwards of “18, 24, or even 36 months” for a “foundational box to fall into place, bit by bit.”
Some expect this to come sooner though. Kyle Samani, a partner at Multicoin Capital, recently explained his thoughts on the whole institutional crypto space in a Business Insider op-ed. Samani explained that over 2019, custodial solutions should be something to watch, as offerings in this space will come to fruition, thus sparking some form of adoption.
Mike Novogratz, too, has expressed that institutions may be coming on rather quick. The Galaxy Digital chief executive recently told Anthony Pompliano that he sees institutions commencing their forays due to the bolstered infrastructure, citing his work as the head of a leading crypto merchant bank.
And with Fidelity Investments’s Tom Jessop recently revealing that there is abounding institutional interest in cryptocurrency, also for their custody service, it seems that asset security could very well be the factor that finally beckons smart money in.

Emurgo-Ledger Partnership Fuels Cardano (ADA) Demand, up 23 Percent

Cardano price up 21.9 percent from last week’s close
Ledger Nano S now supports ADA
A breakout above 6 cents at the back of high transaction volumes means bulls are in control

Ledger Nano S now supports Cardano (ADA) after Yoroi’s integration with the hardware wallet maker. Because of their superior market share, Ledger’s support is beneficial for ADA since more users would be willing to invest and securely hold their assets. Meanwhile, increasing demand could further drive Cardano (ADA) prices above 9.5 cents towards 20 cents.
Cardano Price Analysis
Holders of Cardano (ADA) can now purchase Ledger Nano S and confidently store the coin’s private keys, Emurgo and Ledger have announced. The integration began yesterday after Emurgo, the business wing of the Cardano triage, said Yoroi, the native wallet of ADA, was now supported by ledger devices.
“Ledger, a leader in security and infrastructure solutions for cryptocurrencies and blockchain applications, and EMURGO – the official commercial arm of Cardano, the first peer-reviewed third generation blockchain – are excited to announce full integration of Cardano’s ADA with the Ledger Nano S.”
No doubt, this is a step in the right direction and cements Cardano’s figureheads drive towards making the smart contracting platform mainstream. As the first peer-reviewed and innovative platform, the projects aim is to dislodge Ethereum through a scalable and secure network where quality over quantity (of development and code) is always a top priority.
Besides, while this integration secures user interest, it also reveals Cardano’s preferences. Ledger is a de-facto leader and since inception, it has sold more than 1.5 million devices. Furthermore, it is also the only wallet with certification from the thorough French Cybersecurity Authority, the CSPN.
Candlestick Arrangement

At the time of press, Cardano (ADA) is ahead of the pack, outperforming other assets and up 23 percent from last week’s close. It is the ninth most valuable coin, closing in on USDT and Binance Coin. From candlestick arrangement, we expect ADA to add to their gains.
Not only is it trading within a bull breakout pattern after clearing the 4.5 cents resistance level but accompanying volumes are highs. Because of high participation, BB is widening. Besides, ADA bull bars are banding along the upper BB meaning momentum is equally high favoring buyers.
As a result, every low should be a buying opportunity. The ideal first minor target should be Q2 2018 highs at 9.5 cents.
Technical Indicators
As prices edge higher, transaction volumes should exceed Mar 23 average of 231 million. It is no doubt that sustained volumes would easily propel prices to 9.5 cents.

Financial institutions want to build a ‘back office’ using cryptocurrency, says Ledger CEO Eric Larchevêque

Eric Larchevêque, CEO of the hardware wallet manufacturer, Ledger, opined that the entry of financial institutions into the world of decentralized currency and blockchain, is not just for internal administrative purposes. Larchevêque believes that the crypto-technology could be used by institutions to create a “back office.”
In a podcast with Bloomberg, Larchevêque spoke about institutional investors, the fallout of the CBOE cancelling BTC Futures, the need for a hardware wallet, and the introduction of Ledger Nano X.
The Ledger CEO acknowledged the bearish effect of the crypto-winter. However, he remained confident that the market will hold firm, despite several coins dropping in value.
“Despite the collapse of the price in the recent months, the strategies are still very strong.”
Larchevêque stated that the entry of financial institutions into the cryptocurrency realm was not merely based on the underlying technology of the blockchain, as many have touted. He added that both decentralized currency and the process of tokenization will form the pillar of what could be the back office for institutions.
“Most of the financial institutions have a very strong strategy for the future of crypto because it is not only decentralised cryptocurrencies, it’s also tokenization and basically they really want to build a new back office based on this technology.”
The tokenization process, in the form of initial coin offerings [ICOs], was quickly abandoned after many associated crimes came to be known. A report by CipherTrace stated that over $725 million was stolen in 2018, due to fraudulent initial coin offerings, pyramid schemes, and exit schemes.
With the futures trading not shorting the contract on CBOE anymore, Larchevêque also reiterated his belief that the exit of the exchange could be a positive sign for the coin market.
Back when the CME and the CBOE entered the cryptospace in late-2017, the cryptocurrency market “shot to the moon,” leading to a surge in Ledger hardware wallets. During the period, Ledger sold over a million units, despite an expected sales figure of 30,000.
Larchevêque also cited the plethora of “opportunities” for financial institutions in the virtual currency market now, saying that a positive change in the collective market’s value was imminent.
“The future is really aligned with cryptocurrencies, tokenization, they don’t want to miss the next wave.”

Trezor hits back at Ledger; releases report to counter claims of its wallets being vulnerable to attacks

Trezor wallet responded to Ledger’s claims that its devices were vulnerable to attacks. At the recently held MIT Bitcoin Expo in Boston, Charles Guillemet, the Chief Security Officer at Ledger, had made news after he publicly stated that four of Trezor’s devices were “completely broken.” Ledger later went on to release a report titled “Our Shared Security: Responsibly Disclosing Competitor Vulnerabilities,” which detailed five key vulnerabilities in their competitor’s products.
A day after Ledger published their report, Trezor responded to the assertions made by their competitor, with a report of their own titled, “Our Response to Ledger’s #MITBitcoinExpo Findings.”
Trezor began by stating that the attacks mentioned in their competitor’s report were not “exploitable.” It said,
“Starting off, we would like to highlight the fact that none of these attacks are exploitable remotely. All of the demonstrated attack vectors require physical access to the device, specialized equipment, time, and technical expertise.”
In the Ledger report, the third, fourth and fifth vulnerabilities pertained to the anonymity of data and secret key hacking, requiring physical access to the wallet.
Referencing a report by Binance, Trezor’s report stated that only 5.93 percent of respondents suggested physical attacks or thefts as being the most pertinent threat, with 66 percent suggesting that remote attacks presented a more urgent concern. Based on the study, Trezor stated that the customers concerned with physical attacks can be “protected using a passphrase.”
They further stated that remote attacks were the main purpose of wallet manufacturers,
“The primary purpose of a hardware wallet has always been to protect users and funds against malware attacks, computer viruses, and various other remote dangers (like stealing all funds from Ledger via the Stealth Change Address).”
To Ledger’s first claim that the integrity of Trezor devices can be imitated, Trezor replied,
“There is no way a piece of hardware can inspect itself and verify its integrity. Hardware attestation is not a solution, as hardware modifications can be (and have been) added, resulting in the device confirming it is genuine.”
With respect to the Side Channel Attack vulnerability claimed by Ledger, Trezor stated that this vulnerability was “close by back-porting the way to store data,” relating to the Trezor Model T to Trezor One.
Once the PIN vulnerability is resolved, the secret key extraction using the Side Channel Scalar Multiplication can also be rectified, stated the hardware manufacturer. The aforementioned claims are pegged on the assumption that the attacker has access to the users’ PIN and physical access, which Trezor disputed.
Trezor stated that they were asked by Ledger not to mention the surprise concluding attack due to its wider implications for the microchip industry. They further added that the company refrained from giving any more information to this effect.
Finally, Trezor appealed to its users to set up a passphrase-protected wallet with multiple passphrases for additional security. Marek Palatinus, the CEO of SatoshiLabs and the creator of Trezor hardware wallets, concluded,
“We would like to thank Ledger for practically demonstrating the attack that we have been aware of since designing Trezor. Because we realize no hardware is 100% safe, we introduced the concept of passphrase; that besides plausible deniability eliminates many kinds of physical attacks, like this one.”
Trezor’s response to the claims made by their competitor were summed up as,

Trezor Hardware wallets are vulnerable to cyber attacks, says Ledger’s Chief Security Officer

Ledger, the hardware wallet (HW) manufacturer, revealed it’s competitor, Trezor wallet’s vulnerabilities to cyber attacks. At the recently-held MIT Bitcoin Expo in Boston, Charles Guillmet, Ledger’s Chief Security Officer, presented multiple ways in which the Trezor wallet could be broken into.
The French company, Ledger, like any other cyber-security company, tests out its products to ensure they are robust and resolute against potential hacks. However, the wallet manufacturer also tests out its competitor’s products, not simply to lambast their flaws, but also to compare Ledger’s protection capabilities against their peers.
Guillmet referred to four Trezor devices as “completely broken.” The devices in question were the Trezor One, Trezor T, Keepkey, and B Wallet, which pose such severe security flaws that there is no way to fix them, according to Ledger. In reference to their chief security officer’s statements, Ledger published an article detailing the drawbacks of its competitor.
In the report titled “Our Shared Security: Responsibly Disclosing Competitor Vulnerabilities,” the hardware wallet manufacturer stated that their responsibility to provide security services extended to their entire blockchain ecosystem.
Hence, due to this “shared commitment,” Ledger took the extra step to ensure that their competitor’s wallets can withstand hacks.
Ledger Donjon, the wallet manufacturer’s security team, has an Attack Lab in Paris, where regular defense checks are performed against their own products and that of their competitors.
The report added,
“Critically, when addressing the security of competing products, we always follow the principles of responsible disclosure, informing the impacted party of any vulnerability of their products that our Attack Lab might find, and giving them time to find a fix.”
Four months ago, the Attack Lab discovered five key vulnerabilities in Trezor’s products. The company was contacted and informed about the same. Despite allowing them the “responsible disclosure period” to fix these exploits and providing two extensions, Ledger decided to go public with their findings.
The first vulnerability revealed that the genuineness of the device can be imitated. Exact clones of the original Trezor wallet can be made, allowing hackers to tamper with the device and gain control over the code running on the device. Hackers can potentially insert “cryptographic flaws” and insert malware from the device’s back door.
When contacted by Ledger, Trezor stated that the flaw was out of their model and that users will not suffer the potential hack if the wallets were purchased directly from the Trezor website. However, Ledger had a different perspective,
“In our view, this vulnerability can only be patched by overhauling the design of the Trezor One, and replacing one of its core components to incorporate a Secure Element chip, as opposed to the general purpose chip currently used.”
The second vulnerability was with the PIN of the device. Ledger found that on a stolen or found device, the PIN can be guessed using a Side Channel Attack by measuring the power consumption when a PIN is entered compared to the actual PIN. The report stated,
“We found that the PIN does not protect the funds against an attacker with a physical access to the device.”
In their firmware update 1.8.0, Trezor informed Ledger that the vulnerability was rectified.
The third and fourth vulnerabilities pertained to the anonymity of the data within the device. An attacker with physical access to the Trezor One and Trezor T wallet can remove and potentially delete all the data within the device’s flash memory.
Ledger further revealed that this vulnerability cannot be fixed and that the technical details regarding this would not be mentioned by the wallet manufacturer. However, a stronger passphrase used by the users can be a possible solution.
The fifth and final vulnerability pointed to the ease with which a hacker, with physical access to the device, can use Side Channel Attacks to extract the secret key. The device is prone to this attack during Scalar Multiplication when transactions are being signed. However, to successfully trigger this attack, the device’s PIN needs to be known by the hacker.
Ledger also presented a summary status of the attacks and the severity of the same,

Binance Announce Support of Upcoming Bitcoin Cash Hard Fork

Binance, one of the biggest cryptocurrency exchanges on the planet, has announced full support of the upcoming Bitcoin Cash hard fork scheduled for November 15.
More Companies Announce Bitcoin Cash Hard Fork Policies
Just days after Ledger, one of the largest hardware wallet providers globally, announced their own policy on the upcoming Bitcoin Cash hard fork, cryptocurrency exchange giant Binance has stated that it will be supporting both sides of the split. The news comes via a post on the firm’s designated blog. It reads:
“Binance would like to confirm support for the upcoming Bitcoin Cash hard fork. We will take a snapshot of all Bitcoin Cash balances at UNIX time 1542300000, 2018/11/15 4:40:00 PM (UTC).”
The post goes on to state that the exchange will suspend all deposits and withdrawals an hour before the proposed time of the hard fork. Binance also said that customers should make sure to leave sufficient time for the processing of deposits and that they will make a second announcement after the snapshot to inform users of the resumption of deposits and withdrawals.
Binance are the second major cryptocurrency firm in a week to announce their policy on the upcoming Bitcoin Cash hard fork. On Tuesday, hardware wallet provider Ledger stated via its Medium account that it would be temporarily stopping functionality of Bitcoin Cash services until after the fork had been successfully completed:
“Ledger will suspend the Bitcoin Cash service until it is clear which of these chains will be the stable one, both technically and economically. The reason for closing the service during this time is to prevent unwanted transactions (resulting from “replay attacks”), causing possible loss of funds and other potential issues interacting with Bitcoin Cash during this period of time.”
Ledger went on to state that those wishing to transact using the crypto should use a third-party wallet service but do so at their own risk. The hardware wallet manufacturer added that those simply wanting to store the altcoin could leave funds on Ledgers and would not be impacted.
Bitcoin Cash Price Jumps 10% on Binance Support
In a largely uneventful day for cryptocurrency markets, Bitcoin Cash prices seem to have responded positively to the news of Binance support. Over the last six hours, the price has surged from around $425 to $471. Such a sizeable move makes BCH the second best performer on CoinMarketCap in terms of a 24-hour percentage change.
Such large industry players announcing their policies on the upcoming hard fork may be acting as a signal to investors that the split between the Bitcoin ABC group and Craig Wright’s Satoshi’s Vision is definitely going ahead. Since those holding BCH at the time of the hard fork will receive an equal number of coins on both chains, the prospect of free coins seems the most likely driver for the current price movements.
