[THE #MERGE : TOUT COMPRENDRE EN 5 MINUTES]

Demain, la blockchain #Ethereum délaissera le modèle Proof-of-Work pour devenir une blockchain Proof-of-Stake

Explications et impacts de cet évènement historique pour l’écosystème et pour votre portefeuille

Qu’est-ce que The Merge ?

Comme son nom l’indique, The #Merge (qui signifie en français “La Fusion”) est une évolution du réseau #Ethereum consistant à fusionner deux chaînes :

👉la chaîne principale (qu’on appelle mainnet)

👉la #Beacon Chain Image
Petite explication :

Depuis sa création en Juillet 2015, toutes les transactions, tous les smart-contracts ou encore tous les soldes des comptes sont enregistrés sur le mainnet #Ethereum

C'est ce qu'on appelle la "chaîne d'exécution" ou "chaine principale" ou "mainnet"

Increasing the no of users on-chain requires faster execution times, higher security, & cheaper txn fees.

#Sharding is one solution that claims to scale blockchains to process up to a million txns per second.

What's sharding? How does it work?

Let's find out 🧵👇 Image
2/n
In non-sharded blockchains, each node is responsible for processing every transaction and storing the entire state.

Even if there are 1000 nodes (⬆️ nodes = ⬆️ security), the TPS of the network is limited to the processing power of one node.

This creates a bottleneck.
3/n
Sharding is one of the most viable solutions to this problem.

It focuses on splitting the blockchain into smaller pieces called "shards."

Each shard can process a portion of the total transaction processing load, increasing the network's processing power. Image

I uploaded both to @virusbay_io: beta.virusbay.io/sample/browse/…

and the extracted payload to @anyrun_app: app.any.run/tasks/35c09520…

STDOUT:
Injection Target Process = %ProgramFiles%\Internet Explorer\iexplore.exe
PPID Spoof Parent = True
PPID Spoof Process = explorer
Returned true

@virusbay_io @anyrun_app More info on @mattifestation's method:
1⃣ My favorite implementation uploaded publicly is this Excel file (probably authored by @egyed_laszlo):
2⃣ The first workflow VT sample uploaded was ~1 year ago:
