niekto nejaku tldr analyzu facebookovskej currency? co som zbezne pozrel, tak najhorsie predstavy sa naplnili (nieco ako ripple) - tvarime sa crypto ale je to private a iba zmenime virtualne $ za nasu virtualnu menu. + asi najvacsi target je skor zbavit sa $$ nez konkurovat bitcoinu.

New Models speaks with MAT DRYHURST & KEI KREUTLER, two figures central to Berlin's diverse crypto scene, to unpack the possible impact of Facebook's Libra coin (provided it succeeds). From the Bitcoin villages of Switzerland to Libra as an arm of US foreign policy, this episode takes the coin's tagline at face value asking, _were_ everyone to be invited the the global economy... what would that look like, how would that actually be achieved, and what would the fall out be? (w/ Caroline Busta, Daniel Keller, @LILINTERNET)

strategicky tah ktory sa z praktickeho hladiska pre smrtelnych pouzivatelov javi ako useless haluz... podobne ako kybchain, len s rocnym oneskorenim.

Tady je to dobře rozebraný co to vlastně je
https://medium.com/@lopp/thoughts-on-libra-blockchain-49b8f6c26372

moje tldr je asi takovýto (ale doporucuju precist ten clanek nahore):
* je to podobný ripplu v tom ze to je permissioned (=předem povolený a dohodnutý set validátorů)
* je to podobný ethereu v tom že to používá accounts model (nikoliv utxo model jako bitcoin), a bude to používat něco jako "gas" sytem na placeni poplatků za transakce
* bude to mít nějakou nativní jednotku jejíž hodnotu se budou snažit udržovat pomocí "assetů" (peníze na účtě, možná zlato atd) na stabilní hodnotě

tldr od Aantonopa:
While Facebook's Libra doesn't compete against any open, public, permissionless, borderless, neutral, censorship-resistant blockchains, it *will* compete against both retail banks and central banks. This is going to be fun to watch.

mne prislo zaujimave hlavne toto:

"The key feature of Move is the ability to define custom resource types … the Move type system provides special safety guarantees for resources. A resource can never be copied, only moved."

.. ze vlastne Libra je len defaultna jednotka hodnoty, ale ten system neskor bude moct suportovat rozne ine 'resources'.

Ano.

Jinak toto jde i v Liquid sidechainu od Blockstreamu. A navic v Liquidu si asset muze vytvorit kdokoliv bez povoleni. U te libry to bude predpokladam jen na povoleni..

jj, bol som celkom blizko na zaciatku. v principe je dolezite ten main target voci bankam. chapem, preco je tam partner taky paypal, ale nie je nahodou partnerstvo kontraproduktivne pre visa a mastercard? (tie su tiez zapojene zevraj)

+ konkurencia pre ripple(?)

male firmy inovuju, velke ako visa a mastercard inovuju akviziciou starupov a investovaním do projektov ktore môžu viesť k inovaciam

imho je to konkurence pro vsechny tady ty ripply, stelar lumeny a ja nevim jaky radoby blockchainy, ktery jsou ve skutecnosti jen distribuovanou databazi par validatoru..
+ je to konkurence pro stablecoiny tether, tusd atd..

visa a mastercard - mozna si chteji udrzet pozici platebni site kdyby se to chytlo.. kartove spolecnosti nejsou banky, jim je asi vzasade jedno jestli asset kterym se pres jejich sit plati je dolar, koruna nebo libra..

Libra cryptocurrency | At a glance

- Libra is a digital currency first set up and developed by Facebook, due to be launched in the first half of 2020.
- Facebook will set up a subsidiary called Calibra that will release a "wallet" app for buying and selling Libra. Users of WhatsApp and Facebook will be able to use Libra to send money to one another, and shopping and other features may follow.
- Although envisioned by Facebook, the social network says it will not run Libra. The association in charge of the currency has 28 founders, each with an equal say.
- Libra is designed for fast and cheap payments, and specifically targeted at people in emerging markets without a bank account as well as people sending money abroad.
- Unlike Bitcoin, its value is designed to be stable since it is backed by a reserve of currencies such as the pound and dollar.

ehm, takze je to cryptocurrency ci nie je? lebo hento neni technicky popis, skor biznis

0000010100063540000635900573432008636534086365630863657208636590

je to dalsia cesta, ktora vedie k Bitcoinu.

imho je to iba taky token.

000001010006354000063590057343200863653408636563086365720863657608636596

Tak aj tokeny su crypto-currency, nie? Aj trebars USDT fixovany na dolar je crypto-currency.

myslim, ze nie. ono pod pojmom token sa vseobecne chape kadejaky asset. ale v cc svete sa token chape ako viazany na blockchain, cize napriklad na eth.

co sa tyka USDT, ten mi je fakt zahadou, kam ho zaradit. je to ta prva skupina vseobecneho assetu ale zaroven ma verejny blockchain (ci nie?), hoci netusim ako sa tam potvrdzuju transakcie a kam idu tie vysoke poplatky.
