Musk wil #blockchain inzetten om overheid efficiënter te maken...(Bloomberg).
Beetje terug naar de 2017 hype ?
Een Blockchain is geen efficiënte techniek vergeleken met een centrale database.
Positief is wel dat alle uitgaven van de overheid inzichtelijk zijn.
Maar dan alleen als de blockchain door NIEMAND kan worden aangepast en 100% veilig is.
En dan is #Bitcoin de enige optie. Of komt ineens de hobby blockchain van Musk (Dogecoin) of een nieuwe coin (a la Trump) naar voren.
ik kijk er niet van op ..

Blackrock introduceert #bitcoin voor starters in een video....
Deze grootste vermogensbeheerder ter wereld, beveelt officieel aan om 2% van je beleggingen in #Bitcoin te investeren.
De wereld heeft $900T aan activa, dus dat zou een Bitcoin-waardering betekenen van $900k per BTC.
Hier de advertentie/uitleg van BlackRock, in het Nederlands (vertaald met HeyGen )

2️⃣1 Nvidia 2000 stock is 480 currently
3️⃣With #bitcoin value growing from 1 cent to 100K$ it is time to split
4️⃣Proposed to split BTC into 1/100000000 which we call a sat now
5️⃣100 Bitcoin = 1 $

1️⃣Logischerwijs is een #bitcoin koers tegen 100k$ een logisch moment voor verkoop door 'early adapters'⏬
2️⃣daarmee wordt vooralsnog de vraag vanuit ETF's e.a. opgevangen
3️⃣Wat is het effect?
4️⃣ bij de 100$ en 1000$ grens heeft dit lang (>1jr) geduurd, vóór structurele doorbraak

Now that it is clear that #bitcoin cannot be ignored, the # ECB is taking the attack.
If you got in early, that is not fair, because there is now less left for those who are buying now. So you must be dealt with.

Both nostr (with @primal_app and @damusapp ) and @Pears_p2p (with @keet_io ) are technologies, open source, new decentralized social networks can be build upon.
There is no need for centralisation OR a Blockchain.

I like the developments of the decentralized social networks like nostr (with @npub12vk…pugg and @npub18m7…q955 ) & @keet.io (based on pears.com).
(Check podcasts like @npub1h8n…rpev for details).

the concept (from earlier documentation) is based on DWN nodes that store the history of the identifiers. biggest problem is the size of the nodes and therefore the number of participating nodes will limited. i can not find the latest system requirements.
the original concept is developed when csuwildcat was working at Microsoft in decentralized identifiers.
