What made crypto different from normal bank transfers or other financial services like Paypal or Alipay is that there was no middle man for the first time. Wait, what is a middle man? A middle-man is a central authority like a bank or government that intervenes in a transaction between the sender and recipient.
They have the power to surveill, censor or revert transactions and they can share the sensitive data they collect about you with third parties. They also often dictate which financial services you have access to. Things are different with crypto. Transactions directly connect sender and recipient without having to deal with any central authority. Nobody else will have access to your funds and nobody can tell you what services you can use.
This is possible because of the blockchain technology upon which cryptocurrencies operate. What is a blockchain? Why is it called cryptocurrency? A blockchain is a database of transactions that is updated and shared across many computers in a network. Most blockchains are public, and you can only add data, not remove. That is a lot! This makes established blockchains like Ethereum highly secure. What is the difference between Ethereum and Bitcoin?
Launched in , Ethereum builds on Bitcoin's innovation, with some big differences. Both let you use digital money without payment providers or banks. But Ethereum is programmable, so you can also build and deploy decentralized applications on its network. Ethereum being programmable means that you can build apps that use the blockchain to store data or control what your app can do.
This results in a general purpose blockchain that can be programmed to do anything. As there is no limit to what Ethereum can do, it allows for great innovation to happen on the Ethereum network. While Bitcoin is only a payment network, Ethereum is more like a marketplace of financial services, games, social networks and other apps that respect your privacy and cannot censor you. What can Ethereum do? 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.
What apps are currently being developed on Ethereum? 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 transparent.
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. 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 are the next steps for Ethereum? In August , Ethereum went through one of the most significant upgrades by integrating EIP through the London hard fork.
