What Is a Smart Contract?

A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. The code controls the execution, and transactions are trackable and irreversible. Smart contracts permit trusted transactions and agreements to be carried out among disparate, anonymous parties without the need for a central authority, legal system, or external enforcement mechanism. In simple words, Smart contracts are digital contracts stored on a blockchain that is automatically executed when predetermined terms and conditions are met. How Smart Contracts Work? Smart contracts work by following simple “if/when…then…” statements that are written into code on a blockchain. A network of computers executes the actions when predetermined conditions have been met and verified. These actions could include releasing funds to the appr

Blockchain Solutions in COVID-19 Fight

COVID-19 pandemic brought to the fore the importance of authoritative data and authenticated data sources in the medical field. From the early days of reporting on cases and hospitalizations around the world, individual test results reported by test providers in and outside the regular labs, to vaccine supply chains and vaccination records as shots-in-arms ramp up the health authorities, researchers, pharma industry, and regulators depend on accurate, real-time, trusted data from a vast number of diverse government and commercial organizations. And in some cases, distrust of government authorities makes it vital that the data is stored in a tamper-evident manner so that its integrity can be audited and proven. Scientists around the world depend on data sources from a variety of national and international health authorities. But can they always trust the authenticity and integrity of the data they download and reference in their results? One of the early projects launched in the spri

Smart Contract | Innovation & Technology | Codezeros

Smart contracts are one of the most important byproducts of Blockchain technology when it comes to the impact they could have on our daily life. What are smart contracts? A smart contract is basically a computer code on top of a blockchain that comes with a set of rules that bind the parties to interact with each other in a certain way. In case those pre-defined rules are met, the agreement is automatically enforced without the need for a middleman. How do smart contracts work? The parties involved in a transaction decide to use an options contract. It includes the preset price and pre-defined rules that have to be met in order to complete the transaction and change the ownership of the goods. When a triggering event is hit, the contract is exercised according to the coded terms. Regulators use blockchain to monitor market activity and maintain the privacy of individual actor’s positions. Smart contracts’ functioning is often compared with that of a vending machine that h

Can Bitcoin Regulations Make Cryptocurrency Safer?

The incredible rollercoaster rallying and fall of cryptocurrency prices in 2018 and the growing popularity of different types of cryptocurrency has finally — it seems — caught the notice of regulators. Here’s the thing though , cryptocurrency is not centrally regulated by any government, so every government is taking different approaches to regulate Bitcoin and other cryptocurrencies. There are several areas of regulation that look like they’re coming pretty quickly. These include reporting for tax purposes and regulating initial coin offerings the way that securities are regulated. Even though the actual buying and selling of cryptocurrency with blockchain technology are extremely secure, humans are involved in the trading, the exchanges, and the initial offerings. That means that fraud is already happening. New Bitcoin regulations have the power to change the cryptocurrency market. But most analysts think that that’s going to be in a good way — at least with time. Let’s take

What Is a Stock Loan Fee?

A stock loan fee is a cost an investor pays to borrow stock from their brokerage or another investor. This fee also enables investors to make money from lending shares of stock that are otherwise just sitting in their portfolios. Borrowers can pay this fee to temporarily have stocks that they can then use for short selling or to gain voting rights. Stock loan fees may not be on the radar for much of the general public, but they are a key component within the overall investing industry. Understanding stock loan fees can help individual investors potentially increase their investment returns. Definition and Examples of Stock Loan Fees Stock loan fees are often used to facilitate short selling. With short selling, an investor bets that the price of a stock will decline. To do so, they first need to borrow shares and pay a stock loan fee to the lender. The short seller then sells these borrowed shares to eventually buy the shares back at a lower price. The short seller then returns t

Crypto.com vs. Coinbase

Coinbase is the most popular U.S.-based cryptocurrency exchange and one of the largest exchanges in the world. The platform is mostly for buying and selling cryptocurrencies. Crypto.com is a smaller, newer exchange app with a variety of other features like crypto lending, trading competitions, and a native token that provides users with certain benefits, such as lower fees and cashback rewards on a Crypto.com credit card. Crypto.com can only be used as a mobile app; there is no web-based interface. Crypto.com could be the best option for those who want more than just the ability to buy and sell crypto. More experienced traders or anyone looking for more advanced services might prefer Crypto.com. Coinbase is likely to be the better option for beginners who have little to no experience with cryptocurrency. The platform makes things as easy as possible for those looking to make their first crypto purchase or set up recurring buys. We reviewed Crypto.com versus Coinbase based on sup

What Are Non-Fungible Tokens (NFTs)?

Non-fungible tokens or NFTs are unique digital assets that are based on blockchain technology. Anything can become an NFT—a piece of art, sports memorabilia, or even a tweet. Unlike cryptocurrencies that also use the blockchain network for ownership verification, one NFT cannot be directly exchanged with another NFT. NFTs have existed, in some form, for several years but gained a level of traction in 2020. According to research by NonFungible.com and L’Atelier BNP Paribas, in 2020, the total volume of NFTs traded in the U.S. was $250.85 million, up almost 300% from $62.86 million in 2019. Definition and Examples of Non-Fungible Tokens (NFT) NFTs are tokens offering ownership of digital assets. This ownership is then verified through algorithms on the blockchain. Most NFTs use the Ethereum network for verification. Some trace the origins of NFTs back to tokens called Colored Coins in 2012. Colored coins were essentially bitcoins that were “colored” to give them special properti

How Bitcoin and Blockchain Are Changing Crowdfunding

Blockchain technology is quietly disrupting many industries. Just as in the internet's earliest days, it’s happening without a lot of fanfare. But momentum is gathering, particularly in the area of business fundraising. Bitcoin and blockchain technology are creating new and interesting opportunities in crowdfunding. What Is Blockchain? Traditionally, spreadsheets—much like transactional ledgers—exist in one place at a time. They might be on a person’s computer, or even stored on the web in an application like Dropbox, but they never exist in more than one place at once. Changes must be distributed efficiently to all relevant parties. Google Sheets, on the other hand, are accessible in multiple places at the same time. They live in the cloud and everybody who has access to them can see any changes that are made in real-time. Blockchain is more like Google Sheets than a traditional spreadsheet, but with added security. Unlike Google Sheets—which can be edited by anyone with a

Best Bitcoin Mining Software

Bitcoin is one of the most popular and well-known types of cryptocurrency. But how do you get Bitcoin? You can either purchase Bitcoin or you can "mine" it. The mining process involves using dedicated hardware (e.g., ASICs, FPGAs) that use processing power, as well as software applications, to manage these rigs. If you've decided to get into cryptocurrency mining, here are some of the best Bitcoin mining software to start with. What Is Bitcoin Mining Software? Bitcoin mining software is used to keep the decentralized digital cryptocurrency secure. Miners are rewarded with Bitcoin for tracking and securing transactions known as blockchains. Mining is a way to earn Bitcoin without paying for it, making a trade for it, or putting any money upfront—and software helps you do this. The Bitcoin mining software works in conjunction with Bitcoin mining hardware, which are specialized computers built to mine cryptocurrency. The software is how you connect your hardware wit

Investor's Guide to Blockchain Penny Stocks

Blockchain is the technology behind Bitcoin and other cryptocurrencies. But there’s also a lot of interest in using blockchain as an application for other industries—especially financial, luxury goods, and any other industry where authentication is very important. A blockchain allows multiple parties to collaborate without having to simply trust each other. With blockchain, trust is baked into the technology. That is because no single entity controls the information involved in blockchain transactions. Many companies, including giant ones like IBM and Walmart, are looking at how to offer blockchain-related services or implement this new technology within their own businesses. Still, other blockchain-associated companies are being formed as startups. All of that means there are plenty of opportunities for investors to buy stock in a company that may benefit from increased use of this technology. Some of them are penny stocks, which are not listed on a major exchange (and so are s

Is Ethereum Becoming the New Platform for Startups?

The recent rise in the value of Ethereum has vaulted it to over a billion-dollar capitalization and second only to Bitcoin. Its value is more than four times the value of the third-place crypto-currency, XRP. Ethereum was created by Vitalik Buterin, a college dropout who, although enthused by the potential for Bitcoin, felt that there could be a better platform.1 Buterin, who has been compared to Steve Jobs, feels that his creation provides a robust platform for others to develop on and create powerful applications. Buterin recently released his first production-ready version of Ethereum but even before this release, there had been a rush of startups to utilize the open platform and create blockchain-based businesses for new products and services, or the support of their existing businesses. In 2015, there was a rush of venture capital into Bitcoin and Blockchain companies. This year, the influence and potential of Ethereum are seeing venture money coming in specifically targete
