Coinbase Thinks It’s a Good Idea to Backup Private Keys to the Cloud

On Tuesday (February 12th), cryptocurrency exchange Coinbase said that the Coinbase Wallet app for iOS and Android had been enhanced such that it was now for users to backup an encrypted copy of their private keys to the cloud (iCloud in the case of iOS users and Google Drive in the case of Android users).

Exactly one week after launching Bitcoin (BTC) support on Coinbase Wallet (formerly known as "Toshi"), Coinbase announced that it was "introducing cloud backup for your private keys on Coinbase Wallet". Here is the tweet Coinbase sent out:

According to the blog post by Coinbase Wallet Product Lead Siddharth Coelho-Prabhu, this new feature "provides a safeguard for users, helping them avoid losing their funds if they lose their device or misplace their private keys."

Coinbase thinks although it is great that Coinbase Wallet allows users to experience "the full power of an open financial system" (i.e. " storing their own funds and accessing them anywhere in the world"), this power comes with "great responsibility." Since private keys, which are "generated and stored on your mobile device", are "the only way to access your funds on the blockchain" and owns of non-custodial wallets such as Coinbase Wallet "sometimes lose their devices or fail to backup their 12 word recovery phrase in a safe place, thereby "losing their funds forever," it would be a good for users of Coinbase Wallet to use cloud backup for their private keys, and it is now providing a feature that enables just that.

The new opt-in cloud backup feature provides "the ability to store an encrypted copy of your recovery phrase on your personal cloud account." You will, of course, need to come up with a strong password and a way to remember it somehow, but if "you lose your device or get signed out of the app," you will be able to "easily regain access to your funds with the combination of your personal cloud account (iCloud or Google Drive) and your password."

Coinbase wants you to know that this backup is "encrypted with AES-256-GCM encryption and accessible only by the Coinbase Wallet mobile app." And of course, if you lose the password for this backup, the support staff of Coinbase or your cloud service provider will not be able to help you since they don't keep a copy of this password:

"Coinbase will not have access to your password or funds at any time, preserving your privacy and control. Your cloud backup provider will also not have access to your funds, as only you know the password that decrypts your encrypted recovery phrase."

Although this feature currently only "supports iCloud on iOS devices and Google Drive on Android devices," Coinbase plans "to add support for other cloud services in the future."

Coinbase also wants to remind users that this feature is completely optional and needs to be explicitly activated. Also, it recommends that users also "backup their passphrase manually" after cloud backup activation and "activate Two-Factor Authentication on your personal Google or iCloud accounts to make those accounts harder for attackers to compromise."

Amongst experienced long-time investors in crypto, especially those who strong believe in its ideas of decentralization and self-sovereignty, the reactions on Twitters were quite negative. Here are a few examples:

Binance ‘Unknowingly’ Earns $775K via Staking, Set to Launch Huge XLM Giveaway

On Thursday (July 18), Binance, the world's largest cryptoasset exchange (by adjusted trading volume), made a rather interesting announcement: it had "unknowingly" earned 9.5 million Stellar Lumen (XLM) tokens through staking rewards, and it is going to give all of it away to all Binance users who maintain XLM balances between July 20 and September 1.

Binance explained via a blog post that in August 2018 the Binance team followed the advice of the Stellar Development Foundation "to change some parameters on both cold and hot wallets," which resulted in the exchange "unknowingly" earning staking rewards for its XLM holdings since 31 August 2018.

Then, this week, while the Binance team was considering the idea of adding support for XLM staking, it found out that Binance had earned around 9.5 million XLM tokens (each of which was worth approximately $0.08157 at the time). Binance notes that all "weekly staking rewards between then and now are documented on the blockchain." 

So, the team made two decisions:

  • add support for XLM staking to Binance.com; and
  • give away the aforementioned staking rewards to the Binance community (i.e. Binance users).

This is not the first time that Binance has added staking support to Binance.com. The exchange already "distributes NeoGas for NEO holders, Ontology Gas for Ontology holders, VTHO for VeChain holders, and BitTorrent tokens for TRON tokens."

Here is how this 9.5 million XLM giveaway is going to happen.

From July 20, Binance will support XLM staking. Between this date and September 1, Binance will take "daily snapshots" of XLM balances in Binance user accounts.

Then, on September 1, Binance will "tally average user XLM balances based on these snapshots," and process the distribution of staking rewards to these user accounts (that maintained XLM balances during the staking period). Furthermore, the roughly 9.5 million XLM tokens that Binance has unknowingly earned to date will be distributed as a bonus payment to all Binance users who jave maintained non-zero XLM balances since July 20. 

Binance says in its blog post that it estimates this "one-time distribution of 9,500,000 XLM shared proportionately among Binance users" to be worth "10 to 12 months of typical monthly rewards."

According to a support article published on July 18, here are the details of Binance's "Monthly XLM Staking Airdrop Program":

  • Binance will start these daily XLM balance snapshots at 00:00 (UTC) on 20 July 2019.
  • This is how Binance will calculate the XLM staking distribution:

XLM generated by each user = Total XLM staking rewards received by Binance * User XLM holdings ratio. User XLM holdings ratio = User XLM holdings / Total XLM staked by Binance.

  •  In order to qualify for XLM staking rewards, Binance users must have a balance of at least 10 XLM.
  • This initial distribution of XLM staking rewards will be calculated until 1 September 2019, "with the total amount distributed equal to the staking rewards accrued on holdings during the 43 day period."
  • These XLM staking rewards are calculated on a daily basis and are distributed monthly. 
  • XLM distrubutions will be "completed before the 5th of each month."

In other Binance news, another support article explained that Binance's Margin Trading platform has added support for two margin assets (EOS and LINK), three borrowable assets (BNB, EOS, and LINK), and three margin pairs (EOS/USDT, EOS/BTC, LINK/USDT, LINKBTC).

Binance's announcement about its 9.5 million XLM giveaway may have helped the XLM price. According to CryptoCompare, XLM is currently trading at $0.08914, up 7.96% in the past 24-hour period:
