Privacy and a clean UX design have often been at odds in cryptocurrency apps. But there\u2019s no reason why a bitcoin wallet app can\u2019t have both. <\/p>\n

Blockstream\u2019s newest version (3.2.4) of its bitcoin wallet, Blockstream Green, is a legitimate step forward in combining these two attributes that have previously proven to be far more complex to deploy simultaneously.<\/p>\n

A Tor Bitcoin Wallet for iOS Apps<\/h2>\n

Within this newly updated version of the wallet is an optional, in-app onion routing network (Tor) integration for both Android and iOS users. Before this update, Android users could use Orbot<\/a> as a proxy, but there wasn\u2019t a reliable way for iOS users to use Tor while accessing other apps. Using a VPN outside of an app worked, but it was proven unreliable, risking information leakage.<\/p>\n

Fundamentally, Tor obfuscates a user\u2019s IP address<\/a> from their other information by sending it through a relay of other encrypted servers before it reaches the IP\u2019s intended destination online.<\/p>\n

To understand how this support impacts a Bitcoin user\u2019s wallet privacy, Bitcoin Magazine<\/em> spoke with Lawrence Nahum (@LarryBitcoin<\/a>), creator of Blockstream Green\u2019s precursor, Green Address<\/a>, and now chief architect at Blockstream.<\/p>\n

\u201cWe were looking for something that was simple to use, where we would be certain that Tor would be running in the background all the time,\u201d said Nahum.<\/p>\n

The in-app Tor integration gives iOS and Android users less hassle and more assurance of privacy and security. In simple terms, enabling Tor will mean that the Blockstream servers will continue to have information about the wallet but will not know the wallet user\u2019s IP address or what country they are connecting from. And it\u2019s not just Blockstream that cannot see where Green wallet users are coming from \u2014 by enabling Tor, everyone in a user\u2019s network will be blinded to the fact that they are accessing a Blockstream Green wallet. <\/p>\n

While this means more censorship-resistance for wallet users, the use of Tor itself can still be an undesirable signal in some countries. <\/p>\n

\u201cYou\u2019re still potentially leaking that you\u2019re using Tor, and that may be something you do or don\u2019t want to do,\u201d said Nahum, \u201cespecially in some countries, which is why I think we [Blockstream Green\u2019s developer team] will need to be doubly careful when considering enabling Tor as a default.\u201d<\/p>\n

Nahum also noted that this feature does not hinder blockchain analysis any more than blocking IP address data that hits the Blockstream servers does. <\/p>\n

There are additional ways to hide an IP\u2019s connection to Tor, such as using tunnels, bridges and an additional VPN. Most of these solutions are more complicated for users new to Tor; they can also be less reliable, in the case of VPNs.<\/p>\n

The Tor Bitcoin Wallet User Experience<\/h2>\n

The Tor integration is an early access feature, so it\u2019s still being tested. Based on one hands-on experience and messages from users in the Blockstream Green Telegram channel, there are some loading delays and time-out issues when Tor is enabled. These issues stem from the reality of using Tor right now. After all, the Tor browser is open-source software that is essentially powered by grants and a global team of volunteers. <\/p>\n

Despite any apparent issues at this point, enabling Tor could not be made simpler. If you download the wallet on Android or iOS, then create a wallet, you can select Bitcoin or Liquid, scroll to the bottom and switch on the \u201cconnect with Tor\u201d option. If you\u2019ve already downloaded the wallet, you will need to log out, then back in before you do anything else.<\/p>\n

Includes early release of *integrated* Tor support, no longer need Orbot: easy zero configuration, just tick to enable. (Settings->logout, click liquid\/bitcoin selector, enable "connect with Tor"). And works on iOS too, which has no Orbot, a new 1st: iOS Bitcoin wallet with Tor! https:\/\/t.co\/vRc77Up794<\/a><\/p>\n
