Blockchain-based contracts are becoming more and more popular as sectors like government, healthcare and the real estate industry discover the benefits. Below are a few examples of how companies are using blockchain to make contracts smarter. BurstIQ BurstIQ. Industry: Healthcare. Location: Denver, Colorad An example of such a situation in real estate is the down-payment. The down-payment is one condition, in a chain of events, that the buyer needs to fulfill. With smart contracts, there is a neutral central coordinator. This is a system that people cannot manipulate 1 money + snack selection = snack dispensed. 2. This logic is programmed into the vending machine. A smart contract, like a vending machine, has logic programmed into it. Here's a simple example of how this vending machine might look like as a smart contract: 1 pragma solidity 0.6.11; 2 For example, say there is a dispute on an existing marketplace between a buyer and a seller, the smart contract would easily be able to resolve the dispute as the assets being transacted are not released until all the conditions of the agreement created beforehand are met

We can already see examples of smart contracts being used in the medical industry by the likes of EncrypGen. This is an application that uses smart contracts to transfer patient data in a secure way, allowing no access from third parties.

Prediction Markets and Financial Services - Augur is a decentralised prediction market created on the Ethereum platform, using smart contracts There are multiple examples like that when it is hard to imagine how something unexpected that happens in the real world can be visible to smart contracts. Besides all the above there are also other risks involved in things like regulation or tax but I believe that they can all be eventually solved Smart contracts are just like usual contracts that will let you exchange property, money, shares or anything valuable securely and transparently with a little twist. With smart contracts, you won't be needing any middleman to do your deed. That's the primary difference between regular contracts and smart contracts

But the smart contracts, in this case, need to be really smart and should be thoroughly equipped with all the conditions and scenarios and, needless to say, well tested. For example, you have Ethereum smart contracts acting as an Escrow in p2p Ethereum exchange service called LocalEthereum. Similarly, one can implement smart contracts in real. How smart contracts see the world. Smart contracts exist on the blockchain and can only access data available on-chain. They rely on what's called an oracle to interact with real world, or off-chain, data. An oracle is a source of data that is being fed to a smart contract. For example, oracles provide data like the price of a stock, weather. First, smart contracts are trusted, shared records. They are so secure that individual parties do not need to keep their own backup copies, a boon for modern companies where multiple departments have conflicting workflows due to the lack of a single record of truth. Second, smart contracts are highly deterministic Smart contracts, enabled by blockchain or distributed ledgers, Existing Commercial Contracts Unfit for the World of Real-Time Commerce In the trillion-dollar syndicated loan market, it is still Examples of Rising Problems with Traditional Financial Contracts Non-binary (real-world) contracts include ways to address and resolve disputes. Smart contracts are based on interfaces, business rules, and data. As technology evolves, the smart contracts will need to be upgraded in order to maintain compatibility with the operating platforms and continue to operate correctly
