Best bitcoin and crypto wallets for February 2022
The latter is a token that is a collateral for staked ETH and gives the right to receive staking rewards. You can listen to more articles from The Conversation, narrated by Noa, here. But could this upgrade, a vital step towards a much greener and faster version of the current system, put ethereum on the path to becoming the dominant platform on the internet and make ether number one?
Bitcoin is a system for allowing people to send value between one another without the need for banks. It is built on a technology known as blockchains, which are online ledgers whose transactions are checked and recorded by a decentralised network of computers known as validators. To make this more attractive, bitcoin is relatively scarce: only around 18 million coins are in existence and the protocol is such that there can never be more than 21 million.
Ether works in a similar way to bitcoin, but ethereum is different. It is a worldwide software platform with no host, on which developers are building thousands of blockchain-based applications. This means these applications can all run without being controlled by a company. Examples include cryptocurrency exchanges , insurance systems , and new kinds of gaming.
At the heart of the platform is the idea of smart contracts, which are automated agreements that ensure that money and assets change hands when certain conditions have been fulfilled. All transactions on the platform ultimately use ether, and the success of the platform is why ether has been the second-largest cryptocurrency after bitcoin for the past few years.
The fact that ether fuels the platform — even being referred to as gas fees — gives it a utility and an intrinsic value that bitcoin does not have. Ethereum has several major problems, however. The first is that gas fees have become very expensive in the last couple of years because the network has become so popular and is therefore very congested. Validators prioritise users who are willing to pay the highest fees for their transactions.
Bitcoin has comparable issues with congestion, which its developers are trying to solve by building applications like Lightning on top which boast faster transaction speeds. The second problem for ethereum is that, as it has become more popular, the amount of computational power used by validators has rocketed. Proponents also point out that the network is shifting towards using much more renewable power over time. At any rate, the eventual creation of an ethereum 2.
Without getting into too many details , proof of work is a protocol in which validators all attempt to solve complex equations to prove that each proposed transaction is valid. Many in the bitcoin community are against proof of stake because it gives the most power to the biggest validators, potentially allowing them to corrupt the system of validation if they can get control of more than half of the network.
Ethereum supporters counter that proof of stake has checks and balances built in that would prevent this from happening. Either way, ethereum 2.
The transition to ethereum 2. For the past few months, the new proof-of-stake blockchain has been running in a test format in parallel with the existing system, allowing the developers to prepare it for a merger in The forthcoming upgrade is essentially a warm up for this merger. Known as Altair , it introduces numerous technical changes that are designed to keep validators honest and make the system more decentralised. Certainly the price of ether has been strong ahead of the Altair upgrade.
The recent surge in bitcoin to all-time highs has been helping to lift the entire crypto market. But some of the price movement in ether probably reflects people betting that the upgrade will succeed, while the rest is from speculators switching from bitcoin, and new money moving into the space.
But ultimately the question is what it will mean for bitcoin. Bitcoiners will continue to argue that their protocol is more decentralised than proof of stake, and they have the advantage of being the crypto brand that investors are most comfortable risking their money with. The question is whether these advantages are outweighed by ethereum 2.

How Bitcoin Works
When the richest person in the world gives his support to a virtual currency you know it's big business. Elon Musk has told users of an online social media app that he thinks the virtual currency, Bitcoin, is a "good thing. His comments resulted in the value of Bitcoin rising significantly. As talk of the currency has gone global, the Bank of Singapore has suggested that the year-old currency could replace gold as its store of value. However, in October, the head of the Bank of England, Andrew Bailey, warned about the unpredictability of Bitcoin, saying it makes him, "very nervous". With all this talk you're probably wondering - what is Bitcoin and how does it all work? Here's everything you need to know. Bitcoin, often described as a cryptocurrency, a virtual currency or a digital currency - is a type of money that is completely virtual. It's like an online version of cash.

Cryptocurrency is a type of digital currency that generally only exists electronically. There is no physical coin or bill unless you use a service that allows you to cash in cryptocurrency for a physical token. You usually exchange cryptocurrency with someone online, with your phone or computer, without using an intermediary like a bank. Bitcoin and Ether are well-known cryptocurrencies, but there are many different cryptocurrency brands, and new ones are continuously being created. People use cryptocurrency for quick payments, to avoid transaction fees that regular banks charge, or because it offers some anonymity.

Cryptocurrency bubble risks exposed by Bitcoin's recent slide. They seem to be almost everywhere. Cool looking hipsters livin' the dream after amassing a fortune in the world of crypto. Social media sites are overflowing with them. Even old school glossy magazines, barely clinging to life, have dialled in with tales tall and not so true of the fabulous riches to be earned in the ether. There's no doubt they exist. Those that either got in early or built financial structures that facilitate trades which, none like to admit, replicate old style banks and broking houses, have socked away unimaginable riches.
