Here’s a basic metaphor for how this system would work. And the application uses a token to allow users to interact with the DApp in a decentralized way. All the data from the application is stored in a public blockchain.

The DApp has open source code that anyone can read and verify and it isn’t controlled by any one entity. This is the most important characteristic. So what makes a DApp a DApp? First, the application is decentralized. These applications address many issues and weaknesses that we have in our systems today, but likely most of the revolutionary ideas have not even been created yet.
Companies are created with fascinating ideas that utilize the toolbox that Ethereum provides. This allows people to have an easy-to-use and programmable blockchain that can be customized for their needs. DApps - Decentralized ApplicationsĮthereum allows any company to use their open source code to build upon the Ethereum blockchain. There’s just unfortunately still no way of encoding bragging rights. There is no way to cheat and Bob gets his money. No need for lawyers, judges, courts, or credit. If anyone breaks the terms of the agreement, their money is forfeited. When proof of victory is provided to the contract, the funds release. The contract holds the money with the condition that the winner of the league will receive the funds. A smart contract could be programmed where all the money is sent to the Ethereum contract. But with huge amounts of money, there are serious risks associated with trusting middle men - let alone the additional fees. Trust must be placed in one of these entities for a $10 bet, the risk is minimal. Currently, either one trustworthy member of the league holds the cash, or they must use a third-party site to hold the money. So everyone playing in the league throws in $10. For example, imagine that for Bob, bragging rights are not enough to incentivize him to spend his weeks pouring over football stats. So what does that mean in reality? It means that an unchangeable contract can be created, that can be seen by everyone, and where the terms are automatically enforced. Ethereum enables anyone - well, maybe not anyone considering my grandma still doesn’t have an email account, but anyone with programming knowledge - to program their own smart contracts. Don’t put in the dollar, don’t get the Snickers, it doesn’t matter how much your shake it. If a dollar is put in and A4 pressed, then a Snickers will fall. There is a simple program running inside that receives an input and produces an output. The vending machine that you walk to every ten minutes at work because it’s “not technically a break” is the simplest example of a smart contract. A smart contract on the other hand, is simply a cryptographically secured digital contract that enforces the terms via code.
But since the restaurant might still charge Ron for those crepes after he eats them, we put contracts in writing and rely on lawyers, judges, and our institutions to enforce their terms. If Ron can eat 23 crepes in an hour, then he doesn’t pay the bill (a questionable incentive…but anything goes in college towns).
If Bob wins the fantasy football league, then he has bragging rights for the whole year. In today’s world, contracts can be any agreement, from corporate agreements to that fantasy football league that you WILL win one of these years! But a contract in its simplest form is a “ if” and “ then” agreement. Anyone can deploy an Ethereum smart contract and the blockchain secures them in a decentralized and transparent manner. Vitalik Buterin Smart ContractsĮthereum’s most revolutionary technology is smart contracts. When I came up with Ethereum, my first first thought was, ‘Okay, this thing is too good to be true.’ As it turned out, the core Ethereum idea was good - fundamentally, completely sound. Just as how in the early internet days, porn was the simplest application of the technology, Bitcoin utilizes the simplest function for the blockchain: transactions. But it could support basic images - and teenagers everywhere rejoiced. The internet wasn’t advanced enough to support YouTube, Facebook, and endless animal GIFs. When the internet was first developed, it was used for porn. Buterin created a new blockchain, one that transcended the limitations of transactions. As we understand, Bitcoin uses the blockchain, a decentralized and unchangeable method of information storage, to secure and confirm transactions on the Bitcoin network. This system would solve the current issues of our internet: the lack of available trust. In 2013, Buterin envisioned a decentralized internet, on which anyone could build applications. The Ethereum project is headed by Vitalik Buterin, a 23-year-old, and he truly is one of the geniuses of our time.
