🛒NFT Marketplaces

An NFT Marketplace is a place (usually a website) that connects to your wallet.

It allows you to buy/sell NFT for different Blockchains.

Each one has its own rules/peculiarities.

Examples:
- OpenSea
- Looksrare
- Axie Infinity
- Rarible
- Decentraland

In a nutshell, a bridge between the blockchain and the outside world.

in this thread, based on the Chainlink documentation, I summarize the main parts to get an idea in 5 minutes.

Definition

Oracles are entities that connect blockchains to external systems.

Based on the real-world input/output, oracles enable smart contract execution.

Oracles provide a way for the Web3 ecosystem to access:
- existing data sources
- legacy systems
- advanced computations

🛑BLOCKS!

No, not the Twitter ones...
the BLOCKCHAIN Blocks.

Let's quickly see some concepts related to Eth blocks:
- definition
- blocks & transactions
- block values
- block time
- block size

↓
DEFINITION

Blocks hold batches of hashed and encoded transactions.

Each block includes the hash of the prior block, linking the two, hence forming the chain.

This iterative process confirms the integrity of the previous block, all the way back to the initial GENESIS block.
BLOCKS & TRANSACTIONS

Transactions are batched into blocks, and they are all at once:
- committed
- agreed on
- synchronized

This is to give all the participants time for consensus.

⬛ETHEREUM TRANSACTIONS concepts

DEFINITION

What is a transaction on the Ethereum network?

A Transaction is a cryptographically signed instruction from accounts.

An account will initiate a transaction to update the state of the Ethereum network.

A common transaction is transferring ETH from account A to B.
TRANSACTIONS ARE FOR HUMANS!

A transaction refers to an action initiated by a human who owns an externally-owned account.

Example:
Alice sends ETH to Bob
A -----> B

This causes a change of the state on the EVM (Ethereum Virtual Machine).

The question I get most often about containerization is: "What is a container?".

Let's make it simple, with my 2 favorite definitions:

1. From a logical point of view, it's a single and packaged unit of software.

2. From a technical point of view, it's an isolated process.

↓
From a logical point of view, more understandable for a human, a container can be considered as a single unit of working software, with all its configurations and dependencies, packaged.

In this way, it can run quickly and reliably from one computer to another.
A container has its own dedicated filesystem, provided by an image.

The image contains:
-dependencies
-configuration
-binaries
-environment variables
-other important data related to the container to be instantiated.

Many containers can be run from a single image

DEFINITION of Ethereum Account

It's an entity with an ether (ETH) balance.

Accounts can send transactions on the Ethereum network.

Accounts can be:
- user-controlled.
- deployed as smart contracts.
ACCOUNT TYPES

Two account types:
- Externally-owned: controlled by anyone with the private keys.
- Contract: a smart contract deployed to the network, controlled by code.

Both account types can:
- receive/hold/send ETH and tokens.
- Interact with deployed smart contracts.
