MX Map β€” Email Providers of Baltic Municipalities Interactive map showing the email providers of all ~182 municipalities in Estonia, Latvia, and Lithuania, based on DNS analysis of MX and SPF records.

Estonian municipalities are not at all doing well with digital sovereignty. Most have Microsoft e-mail.

In Estonia, there has been a similar argument made that internet voting favours certain parties. However, it has been done for long enough for these parties to fall out of favour as others started winning. The solution for the critics has been simple: now these other parties are rigging elections. πŸ€·β€β™‚οΈ

I can share that I found out that a smoke alarm in the basement ceiling doubles as a water leak alarm (given a sufficient amount of water in the basement).

How can Europe survive the AI tsunami? Artificial intelligence is making its way into every corner of our society. That is why it is crucial to have a clear strategy for the use of AI and for the values that should guide its actions. At the Digital Tech Summit, Estonian experts contributed to the debate and emphasised that we, as individuals, also bear responsibility – and that with a few simple steps, we can maintain control over the technology ourselves.

You can personally do things to keep your skills and wits with AI.

Travelling to Copenhagen this week to constructively rain on peoples' AI parades at the Digital Tech Summit.

Constructively, I promise. Can't have economic weakness in Europe this time around, or you know, ever.

At least in Estonia, the story of "digital signatures and Smart-ID could be broken by a quantum computer" still raises eyebrows.

If I get cryptographic agility in systems *and* get rid of MD5, I would totally have no cryptographically relevant quantum computer ever. May it do computational chemistry and cold fusion for all I care.

Might be it won't do that either.

Getting rid of MD5 is still a trip to Awesome Town.

Discord user IDs getting leaked is the entirely predictable consequence of requiring platforms to do age verification. That data never goes away, it spreads. In this case, into appeals in a breached customer support database. And predictably, it can get worse. www.404media.co/the-discord-...

My colleagues from Cybernetica and I decided to make another variant of Smart-ID / SplitKey protocol. Coppercloud is a two-party blind RSA signing with private key being split between a user and a server.
Perfect for the future of privacy-preserving digital wallets! 🌐✨
