Go Ethereum

Official Golang implementation of the Ethereum protocol.

A very interesting one, of course especially for Go developers but not only for them.

Web3.js - Ethereum JavaScript API

Very important for frontend developers.

It's a JavaScript API that connects to the Generic JSON-RPC spec.

You need to run a local or remote Ethereum node to use this library.

🧑‍🤝‍🧑Dao VS 🕴️Traditional Organization thread.

DAO: Decentralized autonomous organization.

Both DAOs and traditional organizations need an initial founder or group of founders.

But the way they are conceived and they work is totally different.

🧑‍🤝‍🧑DAO:
technically no paperwork is needed. Decisions are put into the blockchain and done with smart contracts.

🕴️Traditional:
Way more complicated! You need to submit a lot of papers, submit a lot of info. You need certificates, licenses, bank account (of course!).

🎯Centralization VS 🌐Decentralization thread.

Do you remember NAPSTER?

If YES, sorry you are old my friend.

It was a centralized system for distributing pirated music.
Turned off the server, it stopped working.

Let's see PRO/CONS of centralized VS decentralized systems

🎯Centralized
- All participants are connected to the central authority.
- Info propagates quickly.
- The central authority handles propagation.

🌐Decentralized
- Participants may be many edges away from each other.
- Information broadcasts may take a long time

🔲The Merge thread.

In 2022, is planned one of the most important moments for Ethereum: the Merge.

The Beacon Chain will merge into the Mainnet.

And we complain about Git conflicts.

Ethereum enthusiasts are waiting for it as Marvel fans were waiting for "Avenger Endgame".

What is the Merge?

The Mainnet currently works with the proof-of-work consensus.

The Beacon Chain, already shipped in 2020, runs in parallel using proof-of-stake.

The MERGE is when these two systems will collapse in a single one.
