Une vidéo claire sur le sujet.

L'entreprise mandate par les États-Unis poir gérer ses fonds de crypto-monnaies est quand même inquiétante.

Le CTO ou CEO veut que le code généré pour la plateforme passe de 40 à 50% d'ici octobre

Blockchain is a slow, cumbersome, badly designed database that is incredibly energy and material intense to run.
1 single bitcoin transaction:
712.41 kgCO2: carbon footprint of 1,578,956 VISA transactions,
1277.28 kWh of electricity: power consumption of an average U.S. household over 43.78 days
351.20 grams of e-waste: equivalent to the weight of 2.14 iPhones 12
20,130 liters of water: amount of water in a backyard swimming pool.

• very few people seem to be concerned about the mathematical facts
• bitcoin is no money (medium of exchange, measure of value and a store of value=
• as I write this, bitcoin is down to only 53.9% of the value of the total cryptocurrency market. The percentage has been falling since the second cryptocurrency was created.
• many people don't understand that the bitcoin blockchain and the rules associated with it are defined entirely by the software.
• "as developer Gavin Andresen put it in 2015, Bitcoin’s design and evolution 'really comes down to, what code are people running, and how influential are the people who are running the code?" - article on coindesk.com
  • Given that governments are rapidly buying billions of dollars worth of bitcoins (which could be increased to trillions) and are becoming the new bitcoin whales, they now have a say in what changes can be made to the bitcoin software. They could buy enough bitcoin to take control of it and then decide to change the software.

everyone trying to convince me that AI will replace all of the software jobs within the next few years has to get past the obstacle that they always seem to be the same people who were trying to convince me that I’d be going around spending crypto rather than fiat currency “within the next few years” quite a bit more than a few years ago now

Résultat de minage de crypto-monnaies: ~ 700W qui tourne en permanence avec un retour de 14€ / 4 jours environ.

Cependant, il y a le coût de trois cartes graphiques: 2 GTX1080Ti et 1 GTX1060 en plus de la machine.

Le web 0/1 (hébergé par soi-même sur un serveur) a besoin de temps et de compétence
Le web 2 (plateformes de service) échange la vie privée
The web 3 allows to create content at the condition to insert it in a blockchain, so you have to pay for it first. So it has de facto a first barrier of creation or publication.

So the ones more able to publish will be the ones with money they can spend on it.

This “new internet” that has been proposed, much to the disdain of software engineers worldwide, is one where anytime you upload a photo, save something, post a tweet or put something on YouTube, it costs money. Every time you write something to a blockchain with crypto, you need to pay the miners.

As NFTs can be duplicated, do the buyer spend a million dollars for the monky or for the record on the blockchain?

Anyone can write anything on the blockchain if you’ve paid the miners.

And because the blockchain is append-only, how do you comply with law?

C'est complet pour ce qui est officiel jusqu'ici.

99 entreprises posséderont chacune un nœud et pourront voir les transaction effectué sur la blockchain ?

OUI !

Concrètement Facebook n’en saurait pas plus que votre banque actuelle concernant vos achats … mais il va pouvoir croiser ces infos avec vos données personnelles déjà récoltées sur ses différents outils. Cela ira probablement à l’encontre du RGPD, mais on ne va pas chipoter pour si peu. Toutefois, il faudra peut-être à un moment vous poser la question de savoir auquel des 2 types d’organisations vous accordez le plus votre confiance. Les gouvernements / banques ou Facebook ?

J'ai quand même l'impression que cela va mal tourner
