U.S. SEC approves new U.S. exchange with blockchain feed, faster settlement

A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend.

Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation. Cryptocurrencies are digital or virtual currencies underpinned by cryptographic systems. They enable secure online payments without the use of third-party intermediaries.

Cryptocurrencies can be mined or purchased from cryptocurrency exchanges. Not all ecommerce sites allow purchases using cryptocurrencies. In fact, cryptocurrencies, even popular ones like Bitcoin , are hardly used for retail transactions. However, the skyrocketing value of cryptocurrencies has made them popular as trading instruments.

To a limited extent, they are also used for cross-border transfers. Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, blockchain is essentially a set of connected blocks or an online ledger.

Each block contains a set of transactions that have been independently verified by each member of the network. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories. The contents of the online ledger must be agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger. Experts say that blockchain technology can serve multiple industries, such as supply chain, and processes such as online voting and crowdfunding.

JPM are testing the use of blockchain technology to lower transaction costs by streamlining payment processing. Bitcoin is the most popular and valuable cryptocurrency. An anonymous person called Satoshi Nakamoto invented it and introduced it to the world via a white paper in There are thousands of cryptocurrencies present in the market today. Each cryptocurrency claims to have a different function and specification. For example, Ethereum's ether markets itself as gas for the underlying smart contract platform.

Ripple's XRP is used by banks to facilitate transfers between different geographies. Bitcoin, which was made available to the public in , remains the most widely traded and covered cryptocurrency. As of November , there were over Only 21 million bitcoins will ever exist.

In the wake of Bitcoin's success, many other cryptocurrencies, known as "altcoins," have been launched. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch. Fiat currencies derive their authority as mediums of transaction from the government or monetary authorities. For example, each dollar bill is backstopped by the Federal Reserve. But cryptocurrencies are not backed by any public or private entities.

Therefore, it has been difficult to make a case for their legal status in different financial jurisdictions throughout the world. It doesn't help matters that cryptocurrencies have largely functioned outside most existing financial infrastructure. The legal status of cryptocurrencies has implications for their use in daily transactions and trading.

As of December , El Salvador was the only country in the world to allow Bitcoin as legal tender for monetary transactions. In the rest of the world, cryptocurrency regulation varies by jurisdiction. Japan's Payment Services Act defines Bitcoin as legal property. Cryptocurrency exchanges operating in the country are subject to collect information about the customer and details relating to the wire transfer.

China has banned cryptocurrency exchanges and mining within its borders. India was reported to be formulating a framework for cryptocurrencies in December. Cryptocurrencies are legal in the European Union. Derivatives and other products that use cryptocurrencies will need to qualify as "financial instruments. Within the United States, the biggest and most sophisticated financial market in the world, crypto derivatives such as Bitcoin futures are available on the Chicago Mercantile Exchange.

Although cryptocurrencies are considered a form of money, the Internal Revenue Service IRS treats them as a financial asset or property. And, as with most other investments, if you reap capital gains in selling or trading cryptocurrencies, the government wants a piece of the profits. On May 20, , the U. How exactly the IRS would tax proceeds—as capital gains or ordinary income—depends on how long the taxpayer held the cryptocurrency.

Cryptocurrencies were introduced with the intent to revolutionize financial infrastructure. As with every revolution, however, there are tradeoffs involved. At the current stage of development for cryptocurrencies, there are many differences between the theoretical ideal of a decentralized system with cryptocurrencies and its practical implementation. Some advantages and disadvantages of cryptocurrencies are as follows. Cryptocurrencies are digital assets and decentralized systems that allow for secure online payments.

Any investor can purchase cryptocurrency from popular crypto exchanges such as Coinbase, apps such as Cash App, or through brokers. Another popular way to invest in cryptocurrencies is through financial derivatives, such as CME's Bitcoin futures, or through other instruments, such as Bitcoin trusts and Bitcoin ETFs.

Cryptocurrencies are a new paradigm for money. Their promise is to streamline existing financial architecture to make it faster and cheaper. Their technology and architecture decentralize existing monetary systems and make it possible for transacting parties to exchange value and money independently of intermediary institutions such as banks. Cryptocurrencies are generated by mining.

For example, Bitcoin is generated using Bitcoin mining. The process involves downloading software that contains a partial or full history of transactions that have occurred in its network. Though anyone with a computer and an Internet connection can mine cryptocurrency, the energy- and resource-intensive nature of mining means that large firms dominate the industry.

Bitcoin is by far the most popular cryptocurrency followed by other cryptocurrencies such as Ethereum, Binance Coin, Solana, and Cardano. The SEC has said that Bitcoin and Ethereum, the top two cryptocurrencies by market cap, are not securities.

It has not commented on the status of other cryptocurrencies. Because each individual's situation is unique, a qualified professional should always be consulted before making any financial decisions.

A Basic Glossary of Terms for Crypto Newbies

Speculation on the value of blockchain is rife, with Bitcoin—the first and most infamous application of blockchain—grabbing headlines for its rocketing price and volatility. Cryptocurrency market value is subject to high variation due to the specific volatility of the market. Yet Bitcoin is only the first application of blockchain technology that has captured the attention of government and industry. Blockchain was a priority topic at Davos; a World Economic Forum survey suggested that 10 percent of global GDP will be stored on blockchain by Deep shift: Technology tipping points and societal impact , World Economic Forum, September , weforum.

Blockchain, explained

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash. This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of the distributed versions of the chain. Blockchains such as Bitcoin and Ethereum are constantly and continually growing as blocks are being added to the chain, which significantly adds to the security of the ledger. There have been many attempts to create digital money in the past, but they have always failed. The prevailing issue is trust. If someone creates a new currency called the X dollar, how can we trust that they won't give themselves a million X dollars, or steal your X dollars for themselves? Bitcoin was designed to solve this problem by using a specific type of database called a blockchain.

Blockchain technology: implications for operations and supply chain management

In recent years, the rapid development of blockchain technology and cryptocurrencies has influenced the financial industry by creating a new crypto-economy. Then, next-generation decentralized applications without involving a trusted third-party have emerged thanks to the appearance of smart contracts, which are computer protocols designed to facilitate, verify, and enforce automatically the negotiation and agreement among multiple untrustworthy parties. Despite the bright side of smart contracts, several concerns continue to undermine their adoption, such as security threats, vulnerabilities, and legal issues. In this paper, we present a comprehensive survey of blockchain-enabled smart contracts from both technical and usage points of view. To do so, we present a taxonomy of existing blockchain-enabled smart contract solutions, categorize the included research papers, and discuss the existing smart contract-based studies.
