The “proof of work vs proof of stake” debate has been raging for a long time. Many modern projects have opted from proof of stake (POS) over the more traditional proof of work (POW). Your old school currencies like Bitcoin, Zcash, and Ethereum (pre 2.0) were all based on POW. So, in this article, let’s learn more about POW and POS. But first, let’s look into what we mean by consensus algorithms.
Consensus is a method with which a group can reach an agreement dynamically without causing any discord in the group. As such, it's a lot more positive than simple voting, which doesn’t care about the minority's feelings. A mechanism that allows you to reach consensus is known as a “consensus algorithm.” There six rules that consensus algorithms must follow:
Stablecoins are price-stable cryptocurrencies that minimize overall volatility. The importance of stablecoins in crypto adoption simply can’t be underestimated. One of the most significant factors holding back the widespread adoption of cryptocurrencies has been its extreme volatility. Top stablecoins offer an alternative where people can dabble in cryptocurrencies without worrying about volatility. As you can imagine, stablecoins have found tremendous utility in modern cryptosystem.
So, before we delve into a list of stablecoins, let’s understand what are stablecoins and the importance of currency stability.
As we have seen time and time again, currency stability is vital for the overall well-being of the economy. For example, Venezuela is a perfect instance of a country that went through financial turmoil over the last 40 years.

Bitcoin is a cryptocurrency, often referred to as a virtual currency or digital currency, used as a method of exchange or store of wealth. On a very basic level, it is a piece of code. There are no physical coins to speak of, rather, there are UTXOs (unspent transaction outputs) that make up the balance in your wallet.
Bitcoin was created following the financial crash of 2008 as a solution to government and central bank manipulation of money and the...
Those looking into the DeFi field will likely come across the term "yield farming". Yield Farming is the process of putting crypto tokens to productive use in a decentralized finance (DeFi) market to earn interest. Yield Farming takes place on the Ethereum blockchain, and yes, it is a way to earn passive income on Ethereum. But “hodling” ETH tokens is not the same thing as Yield Farming.
This kind of farming is a creative process. It is also a managed process where “farmers” typically hop from one protocol to the next to maximize returns. However, farmers can also employ “set it and forget it” strategies.
Yield Farming became popular with the release of Compound’s COMP governance token. When word got out that farmers could reap Annual Percentage Yields (APY) over 100%, things took off. At present, there is over $4.5 billion Total Value Locked (TVL) in DeFi according to DeFi Pulse.
Governance tokens like COMP offer hodlers...
If you are questioning what cryptocurrency is all about and feeling unsure as to what actually makes Bitcoin valuable, you have come to the right place! In this article, we will explore some of the different reasons people attribute value to this piece of code, why we have currencies to begin with, examine the blockchain technology that underpins Bitcoin, and how Bitcoin’s properties compare to gold.
Bitcoin is a digital currency and store of wealth, created by the pseudonymous developer(s) Satoshi Nakomoto as a solution to dwindling fiat currencies following the stock market crash and economic crisis of 2008. Put simply, Bitcoin was born out of the failings of traditional financial markets and fiat currencies.
Back in 2009, the original Bitcoin blockchain was launched. Along with its launch came the birth of a new technology that would be adopted by thousands of businesses and millions of humans around the globe.
Balancer is an automated market maker (AMM) for multiple tokens. It enables portfolio owners to create Balancer Pools where traders can then trade against these pools. Balancer is still a relatively new liquidity provider (LP) in the decentralized finance (DeFi) space. It only launched in March 2020.
Exchanges, whether they be centralized (CEX) or decentralized (DEX), exist to fulfill buy and sell orders. Their role is to find matches for a wide variety of orders from buyers and sellers so their orders can be executed. Traders rarely find the perfect match on the other side of a trade, so compromises have to be made. Hence, the need for market makers.
A traditional market maker is an individual or member firm of an exchange that buys and sells securities with the primary goal of profiting on the spread. Investopedia describes it this way: “Many market makers are brokerage houses that provide trading services for investors to keep financial markets...
July of 2020 was a pivotal month for the advent of greater cryptocurrency adoption. Several significant announcements in the blockchain space recently point towards increased adoption of cryptocurrency on a global scale. However, the type of adoption in question varies in its appeal and has sparked questions about the future of cryptocurrency and the contrast between its roots and the future uses of the technology.
According to a survey released by HSB in January, at least a third of small-medium sized businesses in the United States accept cryptocurrency as payment for services and goods. The report also indicates that newer companies could be up to twice as likely to accept crypto as payment.
There is a definite shift in how cryptocurrencies are perceived by businesses today from how they have been viewed historically, reflecting the number of merchant services that have recently entered the market. Even fast-food giants such as Subway, Burger King,...
People often turn to Bitcoin and cryptocurrency when they are in need of financial security, but this can be a recipe for emotional investing. Often, this can lead people to become the victim of a Bitcoin scam.
In this article, we will clear up the confusion around whether or not Bitcoin and crypto is a scam. We'll also take a look at the different types of Bitcoin scam formats, how to stop Bitcoin scam emails, and how to tell if you're about to be caught out by a Bitcoin scam or not.
So, is Bitcoin a scam? No, no it is not. Bitcoin is a relatively new technology that serves as a purely transparent, decentralized, and open-source currency. This means that Bitcoin can not be controlled, owned, or manipulated by any governing body or central entity.
Bitcoin is borderless and can be used by anyone in the world with an internet connection.
Due to the strength of the Bitcoin network and the cost to any potential attacker, it would be practically impossible for someone...
Prediction markets use the “wisdom of the crowd” philosophy to make decisions on future events or outcomes. The events predicted can be extremely diverse, such as - elections, sales of a company, price fluctuations of commodities, etc. In this article, we will talk about DeFi prediction markets. These are prediction markets that use the advent of decentralized finance to drive the prediction systems.
So, first thing’s first….
DeFi stands for decentralized finance. It’s a movement that aims to utilize protocols like smart contracts to create decentralized versions of traditional financial products and instruments. A DeFi can be anything from a digital asset, decentralized applications (DApps), financial smart contracts, and protocols that run on top of public blockchains. Some features of these DeFi applications are as follows:
Crypto debit cards seem to be appearing left, right, and center. Each of these offer a bridge between the crypto assets and the traditional financial system, along with various perks and features. In this article we'll take a look at the top five crypto debit cards available, and how they are helping to bring cryptocurrencies to the mainstream.
Currently, there are only a few retailers and merchants that accept Bitcoin or other cryptocurrencies as payment. Though we are still in the very early stages of adoption, traditional financial institutions who have previously dismissed Bitcoin as a scam are now seeking partnerships with cryptocurrency firms to cater to a changing financial landscape.
PayPal, Visa, and MasterCard have come to their senses this year with their decision to make the transition between fiat currency and cryptocurrency smoother. In doing so, they are partnering up with several major crypto players. This aims to offer a...
