Why Proof of Stake (PoS), an alternative to the energy-wasting Proof of Work (PoW), is not currently able to secure blockchain cryptocurrencies.


A topic not emphasized enough with PoS protocols is their lack of resilience in dealing with worst-case scenarios. (...) Thinking about worst case scenarios is an absolute must when dealing with critical systems, and even more important when these systems are on the global scale. (...) So how resilient is a PoW or PoS system under these scenarios? Let’s go through some examples.
- The entire network is forced offline for some period. Then reboot.
- Some portions of the network get partitioned from the main network.
- PoS also fares worse in other worst case scenarios such as stolen private keys.

Tell HN: Tim May, Author of “The Crypto Anarchist Manifesto”, Has Died


The following is from Lucky Green's announcement on Facebook (https://www.facebook.com/lucky.green.73/posts/10155498914786706):

Tim May - Cypherpunks co-Founder, Discoverer of Radiation-Induced Single Event Upsets in Integrated Circuits, Uncompromising Firearms Proponent

Word has reached me that my dear friend, co-conspirator in many things and for many years, fellow Freedom Fighter Tim May passed away earlier this week at his home in Corralitos, California.

Death appears to be from natural causes pending autopsy. I.e. Tim did not die in a hail of bullets as so many who didn’t know Tim all that well and largely from his public writings had predicted.

(...)

Tim’s realization that any Manifesto, Constitution, or Bill of Rights wasn’t worth the paper it was written on absent... show more

Today was another one of those days I was thinking about data privacy!

In an ideal world one would have the advantages of modern technology, without worry or thought of how the technology can betray the user of it.

So I have decided to explore various aspects of digital life, in order to evaluate how an average person can increase their personal privacy while retaining the technological benefits.

There is always a need for a place to start, and for me this will be the smart phone, as its the device nearly everyone has.

My hope is that these post will turn into useful discussions about privacy education, in such a way, as to be accessible to those with little technical knowledge.

How Tutanota replaced Google’s FCM with their own notification system


(before) Tutanota’s Open Source Email App Now Available on F-Droid - https://diasp.org/posts/34ea88208283013611e8047d7b62795e

https://f-droid.org/en/2018/09/03/replacing-gcm-in-tutanota.html
Hi, I’m Ivan and I am developing Tutanota to help build the web of the future where our right to privacy is being respected. I believe that privacy should not be a luxury for the rich and tech-savvy, it should be a basic human right.

GCM (or, how it’s called now, FCM, Firebase Cloud Messaging) is a service owned by Google. We at Tutanota used FCM for our old Android app. Unfortunately, FCM

This week I get to play with hardware at work. That's always a bit of fun. Flashing GnuK onto these little rascals turning them into simple OpenPGP hardware keys.




The programming headers next to the chip was so small I didn't have any header pins that fit. Had to chop the legs of an LED to use as pins. They had just the right size.

Tutanota's Open Source Email App Now Available on F-Droid


Хороший день, хорошая новость! :)
Tutanota's encrypted open source email app is now available on F-Droid, making it the go-to secure email service that enables everybody to stop using Google. To date, no email service has published their Android app on F-Droid, the number one platform for free and open source apps.

Most email services rely on Google’s GCM for push notifications, which make an F-Droid release impossible. If you search F-Droid for email apps, you will not find one app of a known email service, except for Tutanota.

With the app release on F-Droid, Tutanota now proves that it is possible to build a secure email service that is completely Google-free, giving people a real open source

federation v0.17.0 released


The #crypto library pycrypto used has a CVE and unfortunately it doesn't look like the package was being maintained any more. Switched to a more maintained fork (pycryptodome) which has this CVE fixed and provides many other improvements as well.

Please note that pycrypto will need to be uninstalled first, as pycryptodome is a drop-in replacement and they will conflict if the former isn't removed.

Also, code has been moved to a GitLab server. Will set up some mirroring to GitHub soon. Newest release is available on PyPi as before.
