ZCash is having a governance debate thanks to @maxdesalle, @zooko, @matthuang and others. It's a perennial debate because everything DeSalle says about the weakness of governance institutions is correct and yet when it comes to public goods, externalities and increasing returns--all of which are critical for ZCash-there is very little choice but a governance institution. N.B. All DeSalle says also applies to firms! Firms are islands of central planning. Central planning is inefficient. So shouldn't people who appreciate markets want to get rid of firms?! No. The boundary between firms and the… Quoting @matthuang A few thoughts on ZCash (disclosure: Paradigm is an investor in ZEC and ZODL): - All blockchain ecosystems struggle with long-term funding, especially of public goods, and an inflation-funded developer fund is an elegant mechanism to do so. How this fund is allocated is a fair debate, and we should… Related

President of the French Republic since 2017.
Depuis le premier jour, j’ai pris un engagement : protéger nos enfants en ligne. Nous irons au bout. À la suite de la décision rendue par le Conseil constitutionnel à la mi-août sur l’interdiction des réseaux sociaux aux moins de 15 ans, j’avais chargé le Premier ministre de trouver une voie de passage conforme aux observations du Conseil et au droit européen. C’est chose faite. Après un travail technique rigoureux, le Gouvernement notifie aujourd’hui de nouvelles écritures à la Commission, un mois après la décision du Conseil. Cette protection doit aussi devenir la norme pour tous les enfant… English, from French From day one, I made a commitment: to protect our children online. We will see it through. Following the decision made by the Constitutional Council in mid-August on banning social media for under-15s, I had tasked the Prime Minister with finding a way forward that complied with the Council's observations and European law. This has been done. After rigorous technical work, the Government is today notifying the Commission of new submissions, one month after the Council's decision. This protection must also become the norm for all children…

The Republican Party's midterm convention used the traditional red, white and blue decorations - but added Trump's favorite color: gold. I recommend that they use a new US flag. The traditional colors were red for blood, white for purity and blue for justice. The new version features red for blood, gold for wealth and purple for monarchy. Related

We made this something useful for adults and we had this user pay model that could monetize your engagement instead of trying to show you an ad and getting you to leave the game to go somewhere else. It actually the more engaged you were, the more likely you were to, you know, spend money.

It just predicts what you are likely to re-Tweet and like, and linger on. That’s what all these algorithms do. It’s what Tik-Tok does, it’s what all these recommendation engines do. And it turns out that the thing that you are most likely to interact with is outrage. And that’s a quirk of the human condition.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
