Ethereum is a revolutionary technology that will change the way we live our lives. It was designed to function as both an operating system and database for applications, which have been built on top of it over time since its release in 2013. Some notable examples include smart contracts – just one example of how users can use Ethereum’s power beyond finance!

The Ethereum network offers more security than other traditional methods like banks or credit card companies with all transactions being verified through several nodes rather than just 1 single point before going online forever.

Bitcoin vs. Ethereum

Bitcoin and Ethereum are both tokens that exist on virtual networks. However, their purposes change depending on what use case you want for them–while Bitcoin was created as an alternative to national currencies, Ethereum aimed at facilitating contracts with no third-party interference.

While both the Bitcoin and Ethereum networks are powered by the principle of distributed ledgers and cryptography, they differ from each other in many ways. For example; while transactions on the Ethereum network may contain executable code to perform actions when receiving coins or sending them out into circulation (i-e smart contracts), data attached with bitcoins only keep notes about how much money has been sent/received by certain individuals at any given time without actually executing anything themselves – sorta like an account statement but not doing anything except listing numbers.

Both Bitcoin and Ethereum currently use a consensus protocol called Proof-of-work (PoW). This allows the nodes of the Ethereum network to agree on the state of all information recorded on the Ethereum blockchain and prevents certain kinds of economic attacks.

Over the next year, proof-of-work will be phased out in favor of Proof-of-stake (PoS). The transition to proof-of-stake will also phase out mining from Ethereum.

Proof-of-stake validators only need to spend money once to participate — they must buy tokens to win blocks in the proof-of-stake model. In contrast, a miner in a proof-of-work system must purchase mining equipment and keep it running indefinitely, incurring energy costs that can fluctuate.

A major criticism of proof of work is that it is highly energy-intensive because of the computational power required. Proof of stake substitutes computational power with staking—making it less energy-intensive—and replaces miners with validators, who stake their cryptocurrency holdings to activate the ability to create new blocks.

The use of smart contracts are easily coded and widely used on the Ethereum blockchain but is not possible through the Bitcoin blockchain and because Ethereum supports the Bitcoin network, they technically should not compete, however, as more everyday use cases evolve on Ethereum it pushes further and further ahead of Bitcoin as a favorite.

What is Ethereum?

Ethereum is the second-largest digital currency in the market. The initial goal of the Ethereum network was to create a blockchain platform with smart contract functionality on which developers could build and publish dApps, or decentralized applications. These apps are intended for use cases where there’s no risk from downtime or interference by a third party or central authority.

In 2016 Ethereum was hacked resulting in a split of the blockchain; namely Ethereum and Ethereum classic. The hacker made away with $50 million worth of Ether by taking advantage of a third-party project flaw and exploiting a DOA (a smart contract set originating from the Ethereum platform). 

Ethereum Practical Use Cases

Decentralized Finance

One of the most exciting innovations in banking is decentralized finance or DeFi for short. Based on blockchain technologies like those used by cryptocurrencies and other financial products to control money supply or offer services such as loans based on your credit history; this system removes all that power from institutions which allow users more choice when it comes down to how they want their funds managed without being tied down by anyone party’s viewpoint – allowing them greater freedom than ever before!

The markets are always open with DeFi and there’s no central authority to block payments or deny you access. Services that were previously slow become automatic and safer because everything is handled by code.

Non-Fungible Tokens (NFTs)

NFTs are unique tokens that exist on the blockchain and cannot be replicated. They are a digital representation of real-world items which allow creators the ability to transfer their ideas into digital currency but also protect their intellectual property with blockchain technology. NFT’s works seamlessly across any platform built on Ethereum including smart contracts. 

Decentralized autonomous organizations (DAOs)

A DAO is a member-owned committee without centralized leadership that functions primarily on smart contracts. They’re internet-based and have inbuilt treasuries which can’t be accessed without being granted permission by the group. Decisions are made with proposals & voting so everyone can have an opinion. There isn’t any CEO or CFO; instead, all rules about spending come from code written into DAO entities themselves – this way there’s no need for human oversight when something goes wrong (or even better: happens again).

Digital identity

As we continue to prove our existence with paper documentation, the blockchain is making it easier to verify identity digitally. Ethereum enables the verification of identity transparently allowing for ease of transition for governments, companies, and individuals alike. Blockchain technology allows users to create and manage digital identities through the combination of decentralized applications, identity management, and embedded encryption making identity theft easier to spot and more difficult to execute.

Tokenizing real-world assets

The blockchain is a disruptive technology that has the potential to revolutionize how we do business, finance, and manage our assets. Asset tokenization allows for easier transferability by replacing paper-based representations with an electronic version on blockchains which can be accessed anywhere in real-time 24/7 without any downtime.

Health applications

With Ethereum, all hospitals around the world will be able to store and access patient records with ease. This is a key factor in developing new vaccines for viral outbreaks or even preventing them firsthand. Imagine being on vacation in a whole other country and going to the doctor; once you return home for a follow-up, your PCP will have access to your records. Ethereum based smart contracts will enable seamless transitions between providers without worry that information will leak through cracks.

Healthcare overall will benefit from the utilization of Ethereum via the secure management of electronic health records (EHRs), patient consent management, drug traceability, data security in clinical trials, and incentivization through micropayments.

Security infrastructure

Blockchain is a digital ledger that keeps track of anything from currency transactions to votes in elections. The technology behind it provides security through encryption, decentralization, and consensus which ensure trust within the system because there’s no central point for susceptible access or manipulation. The way that each new block connects to all the blocks before it in a cryptographic chain is what makes this distributed ledger so reliable. The transactions within these validated and agreed-upon pieces of information can never be altered or maliciously changed because they’re verified by consensus mechanisms across every single participant on our network, ensuring truthfulness for everyone involved!


Most digital transactions involve some sort of banking involvement which at times can be time-consuming and restrictive depending upon the banks’ terms. As our economy grows, there is less acceptance of error in a financial transaction. Ethereum is going to change the way we do transactions forever! Smart contracts on this network mean that you could exchange anything of value without any risk instantaneously.

Instead of old-school agreements with paper trails – all deals are recorded in computer code. A buyer would put money into an escrow account and the product would then be downloaded. Purchasing directly from the seller with the initiation of a contract, removes the wait time for verification and eliminates the possibility of fraud.

Privacy from third parties

Personal information is collected daily across the internet allowing companies to make billions off data monopoly by selling it to advertisers. Ethereum’s blockchain technology logs every time a search engine uses your information and makes it publicly available forcing corporations to be more careful with how they handle personal data.


The act of altering polls is about as old as the idea of democracy itself…allegedly; that could all change with the implementation of Ethereum. Because the network is not controlled by a central authority and every action is logged and publicly visible, Ethereum will ensure more transparently fair results.

Data Storage

Big companies with high amounts of information to save use server farms to store information in bulk so that it can be accessed more efficiently and cheaply. The downside? If one piece goes down or gets destroyed then there will be severe consequences for the company.

The solution is a decentralized storage facility. This option hasn’t been possible in the past because of the challenge to build a large enough network that could connect all the servers safely while offering a fast transfer. Ethereum is likely to be the solution because the blockchain can be used to encrypt quickly and transfer data between millions of servers.

Initial Coin Offerings

Initial Coin Offerings (ICOs) have been a popular way for early-stage startups to generate funds and sell their tokens. The idea behind an ICO is that each token should function like another asset in your investment portfolio: they’ll redeem themselves only when you need them, such as by using it within one of these applications or simply trading back up again after the purchase price drops below cost base value due user activity over time.


Stable coins, sometimes called ‘stable tokens’, maintain their value by being pegged to another asset. For example, there is a cryptocurrency that’s backed with fiat currencies like the US dollar and commodities such as gold while other stablecoins maintain stability algorithmically through various methods – some even have an entire basket full of major cryptocurrencies! These tools allow you to avoid price volatility when trading on exchanges or just investing in crypto altogether because they provide security against hacking attacks from malicious persons who want nothing more than chaos for everyone involved. Today, many cryptocurrency exchanges have their own stablecoins.


In the shipping industry, Ethereum is being used to track cargo and prevent misplacement of goods. It increases efficiency and reduces costs. Shipping companies will be able to issue secure documentation for their shipments and all parties involved in a transaction are tracked throughout its duration from origin through delivery point-of-use devices that allow users access at any time with just one click – cutting down on paperwork as well.

Enterprise Ethereum

Enterprise Ethereum is an open-source blockchain that provides enterprises with a way to leverage both private and public networks. This enables businesses all over the world, without having any difficulty or uncertainty in regards to which network they should use at any given time!

The Enterprise Ethereum Alliance is a group that was created to help corporations use the new, customizable software and networks based on Ethereum. These are permissioned so clients retain control over their architecture as well as validators which means they can be trusted by businesses since no one else has access besides those in charge of it.

In Conclusion

While Bitcoin paved the way for blockchain technology to become what it is today, Ethereum has expanded on top of that original idea by building an ever-growing network that undergirds all sorts of decentralized applications. From DeFi projects like Stablecoins and Non-fungible tokens (NFTs) to creating a marketplace where anyone can develop their own DAPPs without any coding knowledge needed -ether’s use cases are expansive!
