Help spread awareness for build reproducibility
Please help us spread the word, asking BRD Bitcoin Wallet BTC BCH ETH to support reproducible builds via their Twitter!
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
This provider claims
Trusted by nearly 5 million users in over 170 countries. Nearly $7B USD in cryptocurrency under protection.
which is worrying for your privacy cause “how would they know?”.
Total Bitcoin Cryptocurrency Wallet Privacy
No signup is required and BRD connects directly to blockchain networks, not BRD’s servers. You are in total control of your privacy and bitcoin crypto wallet.
This is a claim which directly implies this app to be non-custodial and they say it explicitly here:
Unhackable Cryptocurrency Security
Store all your valuable cryptocurrency in a virtually unhackable environment, all for free! Your bitcoin crypto wallet is protected on your own device utilizing industry-leading hardware encryption and Apple’s mobile security.
Terms like “Unhackable” and “total security” raise our suspicion though. Nothing is totally secure. Nothing is absolutely unhackable.
But back to the protocol … So the provider claims the app is non-custodial. Can we test that? Where is the source code? No link on App Store …
On their website we find a link to their GitHub and there a repository with a promising name.
So is it reproducible? As all iPhone app, we don’t see how to reproduce this one and neither does the provider claim its reproducibility and we give it the verdict not verifiable.
The app provider also shares code but we could so far not verify that the published code matches the published app!
This verdict means that the provider did share some source code but that we could not verify that this source code matches the released app. This might be due to the source being released later than the app or due to the provided instructions on how to compile the app not being sufficient or due to the provider excluding parts from the public source code. In any case, the result is a discrepancy between the app we can create and the app we can find on GooglePlay and any discrepancy might leak your backup to the server on purpose or by accident.
As we cannot verify that the source provided is the source the app was compiled from, this category is only slightly better than closed source but for now we have hope projects come around and fix verifiability issues.
The app cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The app might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late.
