Blockchain Technology


A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.

One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.

A database usually structures its data into tables, whereas a blockchain, like its name implies, structures its data into chunks (blocks) that are strung together. This data structure inherently makes an irreversible time line of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this time line. Each block in the chain is given an exact time stamp when it is added to the chain.

The goal of blockchain is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain is the foundation for immutable ledgers, or records of transactions that cannot be altered, deleted, or destroyed. This is why blockchains are also known as a distributed ledger technology (DLT).  TO READ MORE ABOUT THIS TECNOLOGY, CLICK HERE...

Supply Side Economics


Supply-side economics is better known to some as "Reaganomics," or the "trickle-down" policy espoused by 40th U.S. President Ronald Reagan.

President Reagan and his Republican contemporaries popularized the controversial idea that greater tax cuts for wealthy investors and entrepreneurs provide them with incentives to save and invest, and produce economic benefits that trickle down into the overall economy.

He often quoted the aphorism "a rising tide lifts all boats" to explain his take on the theory.

Understanding Supply-Side Economics
Like most economic theories, supply-side economics tries to explain both macroeconomic phenomena and—based on these explanations—offer policy prescriptions for stable economic growth.

In general, the supply-side theory has three pillars: tax policy, regulatory policy, and monetary policy. However, the single idea behind all three pillars is that production (i.e. the "supply" of goods and services) is most important in determining economic growth.

The supply-side theory is typically held in stark contrast to the Keynesian theory which, among other facets, includes the idea that demand can falter, so if lagging consumer demand drags the economy into recession, the government should intervene with fiscal and monetary stimuli.

This is the single big distinction: a pure Keynesian believes that consumers and their demand for goods and services are key economic drivers, while a supply-sider believes that producers and their willingness to create goods and services set the pace of economic growth.

The Argument That Supply Creates Its Own Demand
In economics, we review the supply and demand curves. The chart below illustrates a simplified macroeconomic equilibrium: aggregate demand and aggregate supply intersect to determine overall output and price levels. (In this example, the output may be the gross domestic product, and the price level may be the Consumer Price Index.)  READ MORE...
