Solana vs Ethereum: Who’s Gonna Rule the DeFi World?


Home » Guides » Ethereum. Ameer Rosic. If you want to know what is ethereum, how it works, and what it can be used for, without going deep into the technical abyss, this guide is perfect for you. Ethereum is a global, decentralized platform for money and new kinds of applications. On Ethereum, you can write code that controls the money, and build applications accessible anywhere in the world. Although commonly associated with Bitcoin , blockchain technology has many other applications that go way beyond digital currencies.

In fact, Bitcoin is only one of several hundred applications that use blockchain technology today. Until relatively recently, building blockchain applications has required a complex background in coding, cryptography, mathematics as well as significant resources. But times have changed. By providing developers with the tools to build decentralized applications , ethereum is making all of this possible. At its simplest, ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications.

Like Bitcoin , ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability.

Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While Bitcoin is used to track ownership of digital currency bitcoins , ethereum focuses on running the programming code of any decentralized application.

In the Ethereum, instead of mining for bitcoin , miners work to earn Ether, a type of crypto token that fuels the network. Beyond a tradeable cryptocurrency , Ether is also used by application developers to pay for transaction fees and services on the e t hereum network.

There is a second type of token that is used to pay miners fees for including transactions in their block, it is called gas, and every smart contract execution requires a certain amount of gas to be sent along with it to entice miners to put it in the blockchain. However, it is far from the only application. To take a past example of a similar situation, e-mail is one particular use of the internet, and for sure helped popularise it, but there are many others.

Smart contract is just a phrase used to describe a computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met.

Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third-party interference. While all blockchains have the ability to process code, most are severely limited.

Rather than giving a set of limited operations, ethereum allows developers to create whatever operations they want. This means developers can build thousands of different applications that go way beyond anything we have seen before. Before the creation of ethereum applications were designed to do a very limited set of operations.

Bitcoin and other cryptocurrencies , for example, were developed exclusively to operate as peer-to-peer digital currencies. Developers faced a problem. Either expand the set of functions offered by Bitcoin and other types of applications, which is very complicated and time-consuming, or develop a new blockchain application and an entirely new platform as well. I thought they were going after individual applications; they were trying to kind of explicitly support each [use case] in a sort of Swiss Army knife protocol.

It enables anyone to run any program, regardless of the programming language given enough time and memory. The ethereum Virtual Machine makes the process of creating blockchain applications much easier and efficient than ever before. Instead of having to build an entirely original blockchain for each new application, ethereum enables the development of potentially thousands of different applications all on one platform.

Ethereum enables developers to build and deploy decentralized applications. A decentralized application or Dapp serve some particular purpose to its users. Bitcoin, for example, is a Dapp that provides its users with a peer to peer electronic cash system that enables online Bitcoin payments. Because decentralized applications are made up of code that runs on a blockchain network, they are not controlled by any individual or central entity.

Any services that are centralized can be decentralized using ethereum. Think about all the intermediary services that exist across hundreds of different industries. From obvious services like loans provided by banks to intermediary services rarely thought about by most people like title registries, voting systems, regulatory compliance and much more.

A DAO is a fully autonomous, decentralized organization with no single leader. The code is designed to replace the rules and structure of a traditional organization, eliminating the need for people and centralized control. A DAO operates completely transparently and completely independently of any human intervention, including its original creators. Ethereum is also being used as a platform to launch other cryptocurrencies. Because of the ERC20 token standard defined by the Ethereum Foundation, other developers can issue their own versions of this token and raise funds with an initial coin offering ICO.

In this fundraising strategy, the issuers of the token set an amount they want to raise, offer it in a crowd sale, and receive Ether in exchange. Billions of dollars have been raised by ICOs on the ethereum platform in the last two years, and one of the most valuable cryptocurrencies in the world, EOS , is an ERC20 token. Ethereum has recently created a new standard called the ERC token for tracking unique digital assets.

One of the biggest use cases currently for such tokens is digital collectibles, as the infrastructure allows for people to prove ownership of scarce digital goods.

Many games are currently being built using this technology, such as the overnight hit CryptoKitties , a game where you can collect and breed digital cats. Because decentralized applications run on the blockchain , they benefit from all of its properties. Because smart contract code is written by humans, smart contracts are only as good as the people who write them. Code bugs or oversights can lead to unintended adverse actions being taken.

If a mistake in the code gets exploited, there is no efficient way in which an attack or exploitation can be stopped other than obtaining a network consensus and rewriting the underlying code. This goes against the essence of the blockchain which is meant to be immutable. Also, any action taken by a central party raises serious questions about the decentralized nature of an application. There are many ways you can plug into the ethereum network, one of the easiest ways is to use its native Mist browser.

Like web browsers give access and help people navigate the internet, Mist provides a portal into the world of decentralized blockchain applications.

There is also the MetaMask browser extension, which turns Google Chrome into an ethereum browser. MetaMask allows anyone to easily run or develop decentralized applications from their browser. Even people without a technical background can now potentially build blockchain apps. This is a revolutionary leap for blockchain technology that could bring decentralized applications into the mainstream. The ethereum platform is being used to create applications across a broad range of services and industries.

Here are a few exciting projects. Weifund provides an open platform for crowdfunding campaigns that leverages smart contracts. It enables contributions to be turned into contractually backed digital assets that can be used, traded or sold within the Ethereum ecosystem. Uport provides users with a secure and convenient way to take complete control of their identity and personal information. Instead of relying on government institutions and surrendering their identities to third parties, users control who can access and use their data and personal information.

BlockApps is looking to provide the easiest way for enterprises to build, manage and deploy blockchain applications. From the proof of concept to full production systems and integration with legacy systems, Blockapps provides all the tools necessary to create private, semi-private and public industry-specific blockchain applications. Provenance is using ethereum to make opaque supply chains more transparen t.

Predictions on future real-world events, like who will win the next US election, are carried out by trading virtual shares. If a person buys shares in a winning prediction, they receive monetary rewards. Remember how ethereum can be used to build Decentralized Autonomous Organizations? Well in , something bad happened. The DAO was a project developed and programmed by a team behind another startup called Slock. Their aim was to build a humanless venture capital firm that would allow investors to make decisions through smart contracts.

While the attack was made possible by a technical flaw in The DAO software, not the ethereum platform itself, the developers and founders of ethereum were forced to deal with the mess. The hard fork moved the stolen funds to a new smart contract designed to let the original owners withdraw their tokens. But this is where things get complicated.

The implications of this decision are controversial and the topic of intense debate. By executing a hard fork and rewriting the rules by which the blockchain executes, ethereum set a dangerous precedent that goes against the very essence of blockchain.

While another less aggressive soft fork solution was put forth, the ethereum community and its founders were placed in a perilous position. On the other hand, recovering investor money required actions that went against the core ideals of decentralization and set a dangerous precedent.

But not everyone agreed with this course of action. This resulted in a split where two parallel blockchains now exist.

For those members who strongly disagree with any changes to the blockchain even when hacking occurs there is Ethereum classic. For the majority who agreed to rewrite a small part of the blockchain and return the stolen money to their owners, there is ethereum. Both ethereum blockchains have the same features and are identical in every way up to a certain block where the hard-fork was implemented. This means that everything that happened on Ethereum up until the hard-fork is still valid on the Ethereum Classic.

From the block where the hard fork or change in code was executed onwards, the two ethereum blockchains act individually. Despite the fallout from The DAO hack, ethereum is moving forward and looking to a bright future. By providing a user-friendly platform that enables people to harness the power of blockchain technology, ethereum is speeding up the decentralization of the world economy.

Decentralized applications have the potential to profoundly disrupt hundreds of industries including finance , real estate, academia, insurance, healthcare and the public sector amongst many others. Most significant companies will run business processes on their private blockchains. Private blockchains: Within two years , major companies will conduct several business processes on their own private, permissioned corporate blockchains. Consortia blockchains: In two years , many companies will have started to build bottom-up consortia blockchains with a small number of counterparties in their ecosystem collaborating on a small number of use cases to share trusted source-of-truth infrastructure, supply or value chains.

Business use of public blockchains: Some companies will employ public ethereum with their use cases that employ the same stack of blockchain components that they have purchased or built for their private Ethereum-based implementations.



What Is Ethereum and What Are Its Use Cases?

In recent years, none have been more contentious than the battles over which cryptocurrency and blockchain pair will eventually come to dominate the rest. Since the beginning of the crypto wave, the clear consensus choice has been Bitcoin, which has sat atop the market capitalization charts from the earliest days. As the grandfather of all cryptocurrencies, the Bitcoin blockchain is beginning to show its age. It suffers from a variety of real-world limitations, not least of which is its inability to scale.

The blockchain paradigm when coupled with cryptographically-secured transactions has demonstrated its where Υ is the Ethereum state transition function.

Ethereum could change the way we use the internet and protect our personal data

One of the hottest technologies of late is blockchain. A blockchain is a digital transaction of records that's arranged in chunks of data called blocks. These blocks link with one another through a cryptographic validation known as a hashing function. Linked together, these blocks form an unbroken chain - a blockchain. A blockchain is programmed to record not only financial transactions but virtually everything of value. Another name for blockchain is distributed ledger. In this article, I explain the basic ideas behind a blockchain and how it works. Once the fundamentals of blockchain are out of the way, I dive into one of the key features behind the Ethereum blockchain: smart contracts.


Writing Smart Contracts in Ethereum Blockchain

The term decentralized finance DeFi refers to an alternative financial infrastructure built on top of the Ethereum blockchain. DeFi uses smart contracts to create protocols that replicate existing financial services in a more open, interoperable, and transparent way. This article highlights opportunities and potential risks of the DeFi ecosystem. I propose a multi-layered framework to analyze the implicit architecture and the various DeFi building blocks, including token standards, decentralized exchanges, decentralized debt markets, blockchain derivatives, and on-chain asset management protocols. I conclude that DeFi still is a niche market with certain risks but that it also has interesting properties in terms of efficiency, transparency, accessibility, and composability.

What is Ethereum?

Bitcoin may be the most mainstream cryptocurrency, but the Ethereum community has ambition. There are thousands of digital currencies zipping through the virtual world, but if Bitcoin is the alleged future of money, what is Ethereum? CoinTelegraph defines Ethereum as a decentralised blockchain network powered by the Ether token which enables users to make transactions, earn interest on their holdings through staking, use and store nonfungible tokens NFTs , trade cryptocurrencies, play games, use social media and much more. Each node holds a copy of that computer, meaning that any interactions must be verified so everyone can update their copy. Miners validate these blocks before committing them to the network and acting as transaction history or a digital ledger. Mining to verify transactions is known as a proof-of-work PoW consensus method.

These applications provide distinct trade-offs which are very effective for extensive division of decentralized applications. Specific importance is given on conditions where applications require rapid development time, efficient interaction, and security for moderate and seldom utilized applications. Vitalik Buterin, a programmer and co-founder of Bitcoin magazine, initially described Ethereum in a white paper in late intending to build decentralized applications. Buterin proclaimed that Bitcoin and blockchain technology could benefit from other applications besides money and needed a more robust language for application development that could lead to attaching real-world assets, such as stocks and property, to the blockchain.
