Coin wars ethereum

Bitcoin has been controversial since its beginning in , as have the subsequent cryptocurrencies that followed in its wake. While widely criticised for its volatility, its use in nefarious transactions and for the exorbitant use of electricity to mine it, Bitcoin is being seen by some, particularly in the developing world, as a safe harbour during economic storms. But as more people turn to cryptos as either an investment or a lifeline, these issues have manifested in an array of restrictions on their usage. The legal status of Bitcoin and other altcoins alternative coins to Bitcoin varies substantially from country to country, while in some, the relationship remains to be properly defined or is constantly changing. Some countries have placed limitations on the way Bitcoin can be used, with banks banning its customers from making cryptocurrency transactions. Other countries have banned the use of Bitcoin and cryptocurrencies outright with heavy penalties in place for anyone making crypto transactions.

Gas Wars and The Hotgate

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.

First proposed as a research project in , the blockchain concept predated its first widespread application in use: Bitcoin, in In the years since, the use of blockchains has exploded via the creation of various cryptocurrencies , decentralized finance DeFi applications, non-fungible tokens NFTs , and smart contracts.

This company owns a warehouse building that contains all of these computers under one roof and has full control of each of these computers and all of the information contained within them. This, however, provides a single point of failure.

What happens if the electricity at that location goes out? What if its Internet connection is severed? What if it burns to the ground? What if a bad actor erases everything with a single keystroke? In any case, the data is lost or corrupted. What a blockchain does is to allow the data held in that database to be spread out among several network nodes at various locations.

This not only creates redundancy but also maintains the fidelity of the data stored therein—if somebody tries to alter a record at one instance of the database, the other nodes would not be altered and thus would prevent a bad actor from doing so. This system helps to establish an exact and transparent order of events. This way, no single node within the network can alter information held within it. Because of this, the information and history such as of transactions of a cryptocurrency are irreversible.

To prevent bad actors from validating bad transactions or double spends , blockchains are secured by a consensus mechanism such as proof of work PoW or proof of stake PoS. These mechanisms allow for agreement even when no single node is in charge. Each node has its own copy of the chain that gets updated as fresh blocks are confirmed and added. This means that if you wanted to, you could track Bitcoin wherever it goes.

For example, exchanges have been hacked in the past, where those who kept Bitcoin on the exchange lost everything. While the hacker may be entirely anonymous, the Bitcoins that they extracted are easily traceable. If the Bitcoins stolen in some of these hacks were to be moved or spent somewhere, it would be known.

Of course, the records stored in the Bitcoin blockchain as well as most others are encrypted. This means that only the owner of a record can decrypt it to reveal their identity using a public - private key pair. As a result, users of blockchains can remain anonymous while preserving transparency. Blockchain technology achieves decentralized security and trust in several ways.

To begin with, new blocks are always stored linearly and chronologically. After a block has been added to the end of the blockchain, it is extremely difficult to go back and alter the contents of the block unless a majority of the network has reached a consensus to do so.

Hash codes are created by a mathematical function that turns digital information into a string of numbers and letters. If that information is edited in any way, then the hash code changes as well. Such an attack would also require an immense amount of money and resources, as they would need to redo all of the blocks because they would now have different time stamps and hash codes. Due to the size of many cryptocurrency networks and how fast they are growing, the cost to pull off such a feat probably would be insurmountable.

This would be not only extremely expensive but also likely fruitless. Doing such a thing would not go unnoticed, as network members would see such drastic alterations to the blockchain. The network members would then hard fork off to a new version of the chain that has not been affected. This would cause the attacked version of the token to plummet in value, making the attack ultimately pointless, as the bad actor has control of a worthless asset. The same would occur if the bad actor were to attack the new fork of Bitcoin.

It is built this way so that taking part in the network is far more economically incentivized than attacking it. Blockchain technology was first outlined in by Stuart Haber and W. Scott Stornetta, two researchers who wanted to implement a system where document time stamps could not be tampered with. The Bitcoin protocol is built on a blockchain. The key thing to understand here is that Bitcoin merely uses blockchain as a means to transparently record a ledger of payments, but blockchain can, in theory, be used to immutably record any number of data points.

As discussed above, this could be in the form of transactions, votes in an election, product inventories, state identifications, deeds to homes, and much more. Currently, tens of thousands of projects are looking to implement blockchains in a variety of ways to help society other than just recording transactions—for example, as a way to vote securely in democratic elections. For example, a voting system could work such that each citizen of a country would be issued a single cryptocurrency or token.

Each candidate would then be given a specific wallet address, and the voters would send their token or crypto to the address of whichever candidate for whom they wish to vote. The transparent and traceable nature of blockchain would eliminate both the need for human vote counting and the ability of bad actors to tamper with physical ballots.

Blockchains have been heralded as being a disruptive force to the finance sector, and especially with the functions of payments and banking. However, banks and decentralized blockchains are vastly different. Today, there are more than 10, other cryptocurrency systems running on blockchain.

But it turns out that blockchain is actually a reliable way of storing data about other types of transactions as well. For example, IBM has created its Food Trust blockchain to trace the journey that food products take to get to their locations. Why do this? The food industry has seen countless outbreaks of E. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating. If a food is found to be contaminated, then it can be traced all the way back through each stop to its origin.

Not only that, but these companies can also now see everything else it may have come in contact with, allowing the identification of the problem to occur far sooner and potentially saving lives. This is one example of blockchain in practice, but there are many other forms of blockchain implementation. Perhaps no industry stands to benefit from integrating blockchain into its business operations more than banking.

Financial institutions only operate during business hours, usually five days a week. That means if you try to deposit a check on Friday at 6 p. Even if you do make your deposit during business hours, the transaction can still take one to three days to verify due to the sheer volume of transactions that banks need to settle.

Blockchain, on the other hand, never sleeps. By integrating blockchain into banks, consumers can see their transactions processed in as little as 10 minutes—basically the time it takes to add a block to the blockchain, regardless of holidays or the time of day or week. With blockchain, banks also have the opportunity to exchange funds between institutions more quickly and securely.

In the stock trading business, for example, the settlement and clearing process can take up to three days or longer, if trading internationally , meaning that the money and shares are frozen for that period of time. Given the size of the sums involved, even the few days that the money is in transit can carry significant costs and risks for banks.

Blockchain forms the bedrock for cryptocurrencies like Bitcoin. The U. In , several failing banks were bailed out—partially using taxpayer money. These are the worries out of which Bitcoin was first conceived and developed. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority.

This not only reduces risk but also eliminates many of the processing and transaction fees. It can also give those in countries with unstable currencies or financial infrastructures a more stable currency with more applications and a wider network of individuals and institutions with whom they can do business, both domestically and internationally.

Using cryptocurrency wallets for savings accounts or as a means of payment is especially profound for those who have no state identification. Some countries may be war-torn or have governments that lack any real infrastructure to provide identification. Citizens of such countries may not have access to savings or brokerage accounts—and, therefore, no way to safely store wealth. When a medical record is generated and signed, it can be written into the blockchain, which provides patients with the proof and confidence that the record cannot be changed.

These personal health records could be encoded and stored on the blockchain with a private key, so that they are only accessible by certain individuals, thereby ensuring privacy. In the case of a property dispute, claims to the property must be reconciled with the public index.

This process is not just costly and time-consuming—it is also prone to human error, where each inaccuracy makes tracking property ownership less efficient. Blockchain has the potential to eliminate the need for scanning documents and tracking down physical files in a local recording office.

If property ownership is stored and verified on the blockchain, owners can trust that their deed is accurate and permanently recorded. If a group of people living in such an area is able to leverage blockchain, then transparent and clear time lines of property ownership could be established.

A smart contract is a computer code that can be built into the blockchain to facilitate, verify, or negotiate a contract agreement.

In War Of Cryptocurrencies, Why Ethereum Is Outperforming Bitcoin

These are the core obsessions that drive our newsroom—defining topics of seismic importance to the global economy. Our emails are made to shine in your inbox, with something fresh every morning, afternoon, and weekend. While at least 26 publicly traded companies hold bitcoin , just one owns more than half of all cryptocurrency on corporate balance sheets. The biggest corporate bitcoin holder is the Virginia-based business intelligence software maker MicroStrategy, according to a database from the crypto analytics firm CoinGecko. MicroStrategy bought its first tranche of bitcoin in August , citing worries that the US dollar would lose value thanks to the pandemic , financial stimulus measures from governments around the world, and global political uncertainty.

Do these arguments hold any water? This piece first appeared in our new twice-weekly newsletter, Chain Letter, which covers the world of blockchain and cryptocurrencies. Perhaps the most striking finding is that the process of verifying transactions and securing a blockchain ledger against attack, called mining, is not actually that decentralized in either system. But organizations have formed to pool mining resources. That might indicate that Bitcoin is more corporatized, Sirer says. Numbers like these may help clarify some debates. Hundreds of cryptocurrencies now exist, and many of them work differently from Bitcoin and Ethereum. Not all of them rely on miners or even use a blockchain.

How China Took Center Stage in Bitcoin’s Civil War

Representations of virtual currency Bitcoin are seen in this picture illustration taken taken March 13, Bitcoin is beginning to reassert its dominance over challengers to its cryptocurrency crown. Yet bitcoin has stemmed its loss of market share last month, and begun to regain ground, as rattled investors seek the relative safety of the biggest crypto player while they contend with an aggressive Fed and talk of war in Europe. Nonetheless, some say year-old bitcoin could continue to benefit versus its crypto rivals from the more cautious investment climate. While most cryptocurrencies still take their price cues from bitcoin, some fund managers expect a gradual divergence, or decoupling, this year that will require more discrimination. Cryptocurrencies which are connected to blockchains used to build decentralized finance applications have lost even more ground.
