Lectures et critiques constructives sur des exposées: Cas de POLKADOT

<center>![Polkadot-DOT-annonce-un-fonds-de-developpement-de-plus-de-770-millions-de-dollars.jpg](https://files.peakd.com/file/peakd-hive/valcvr/Eo45r2NpHY8vN9eex5j1pS4o5CUKQMgRrMkqFsAn327H9x86FcGcp41ti9ajosk3zMT.jpg) </center> 

# Qui suis-je ?
* Une élève ingénieur en développement et génie logiciel qui, depuis plusieurs années, utilise, investis et est passionnées  par les systèmes de programmation et développement informatique (surtout par les DLT system “Distributed-Ledger-Technology” (Blockchain, Tangle, Hashgraph, ...).
* [Pour mieux me connaitre](hive/@linlove/let-s-get-know-more)

# Pourquoi, j'ai choisi de porter un regard sur vos travaux ?
* Simplement pour contribuer modestement de façon constructive aux efforts que vous avez réalisés.
* Avant de commencer cette lecture, je tiens à vous féliciter de cette initiative très innovante.

# Les supports de cette lecture

# Mes lectures et commentaires
## 1. Lecture sur XRP
* [Présentation de la société Ripple (Cryptomonnaie XRP)](/hive-114606/@chrispietro98/presentation-de-la-societe-ripple-cryptomonnaie-xrp) par @chrispietro98
* [Voir mes critiques personnelles](/hive-181450/@linlove/lectures-et-critiques-constructive-sur)

## 2. Lecture sur polkadot
* [Présentation du projet POLKADOT](/hive-114606/@valcvr/presentation-du-projet-polkadot) par @valcvr (COUVREUR Valentin)
* Ce qui est très intéressant dans la présentation de ce projet, c'est l'approche très simpliste qui dès le départ crée des catégorisations et des explicitations de concepts fondamentaux (centralisé versus décentralisé, ProofofWork versus ProofofStake, Cross chain / ParaChain / RelayChain / ParaThread, DeFi,...). Cependant certaines dichotomies simplificatrices restreignent parfois la complexité réelle (par exemple réduire les proof of XXX a seulement of Work ou of Stake est faux (voir par exemple le cas de Ripple)) 
* Il aurait été intéressant de mieux préciser la difficulté de mettre en place les « Parachains» et et les « Smart Contracts » (pour l'infalsifiabilités) et qui sont parmi les conditions nécessaires de la fonctionnalité de POLKADOT
* Un grand bravo pour avoir utilisé les chaines youtube 
> **Polka France** (https://www.youtube.com/channel/UCxVRsdcO1g4vny34sIr6qGw) (avec quelques erreurs résultantes de la simplification dichotomique)
---
> **Whiteboard Crypto** (pour l'explicitation graphique)
Le comment de l'interconnectivité / intercontact / interopérabilité des blockchains

# Pour une question ?
* La questions qui reste floue une "Parachain" peut-elle être considéré comme décentralisée ? ou peut ont avoir des "Parachains" centralisées ?

# Pour plus d'explicitations
* Dans les processus et algorithmes GRANDPA (GHOST-based Recursive ANcestor Deriving Prefix Agreement) et BABE (Blind Assignment for Blockchain Extension) il aurait été très intéressant d'expliciter, entre autre, le système de consensus hybride exploité par POLKADOT
> : C'est une façon qu'utilise POLKADOT afin d'obtenir les avantages de la finalité probabiliste (la capacité de toujours produire de nouveaux blocs) et de la finalité prouvable (avoir un accord universel sur la chaîne canonique sans possibilité de retour) (Probabilistic finality versus+add Provable finality)
---
* Le système de Swap très intéressant et qui actuellement interconnecte plusieurs cryptos n'a pas été traité (sauf 1 fois cité sur la dernière image du pdf)

* Je conseil vivement le wiki de polkadot (en anglais)
> https://wiki.polkadot.network/

* Une comparaison graphique permet de mieux comprendre les atouts des trios concurrents (alternatives) Polkadot / Avalanche / Cosmos 

> https://medium.com/avalanche-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b 

Ou entre Polkadot / Etherium / Cosmos
