What Are Remittances? How Do They Impact the Global Economy?

Migrant communities have become a significant demographic in the globalized economy. According to the International Labor Organization (ILO), there were 169 million global migrant workers in 2019. Often, residents of developing nations migrate to high-income countries in search of job opportunities. And once migrants start earning, they typically send money to family members in their country of origin. 

With rising technological advancements, remittances have become a lifeline for millions of people in developing regions. These payments account for a large share of the national gross domestic product (GDP) in some countries. 

To understand the global economy, learn what remittances are and how they function.

In telecommunications and software engineering, a "node" refers to a more extensive interconnected network component. In crypto, however, a node is one of the components that run a blockchain's algorithm to verify and authenticate each transaction.

A blockchain is essentially a digital distributed ledger that records all cryptocurrency transactions. As the name implies, each blockchain is a series of "chained" blocks. 

Every blockchain is made of nodes. Nodes are generally computer systems that contain a copy of a blockchain's primary protocol and its entire transaction history. Due to decentralization, any individual can run a node anywhere in the world as long as they’re connected to a decentralized blockchain network and have the required resources.

Read on to find out the various types of nodes, their functions, and what you can do if you want to run a node.

Blockchain nodes are the building blocks of the crypto ecosystem. Find out why nodes are so important and how they keep crypto decentralized and running.

Smart contracts aren’t a new concept. In fact, the term "smart contract" was coined in 1994 by computer engineer and cryptographer Nick Szabo. To answer “what is a smart contract,” Szabo said, “A smart contract is a computerized transaction protocol that executes the terms of a contract."

“I call these new contracts ‘smart’ because they are far more functional than their inanimate paper-based ancestors,” Szabo said. “No use of artificial intelligence is implied. A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on these promises.”

Based on his work with cryptocurrency and digital contracts, many authors and journalists speculate that Szabo is Satoshi Nakamoto, the pseudonymous inventor of Bitcoin (BTC).
