Insiders vouch that it is extremely hard for our voting system to be rigged, but nonetheless, smart contracts would allay all concerns by providing an infinitely more secure system. Ledger-protected votes would need to be decoded and require excessive computing power to access. No one has that much computing power, so it would need God to hack the system! Secondly, smart contracts could hike low voter turnout. Much of the inertia comes from a fumbling system that includes lining up, showing your identity, and completing forms. With smart contracts, volunteers can transfer voting online and millennials will turn out en masse to vote for their Potus.
The blockchain not only provides a single ledger as a source of trust, but also shaves possible snarls in communication and workflow because of its accuracy, transparency, and automated system. Ordinarily, business operations have to endure a back-and-forth, while waiting for approvals and for internal or external issues to sort themselves out. A blockchain ledger streamlines this. It also cuts out discrepancies that typically occur with independent processing and that may lead to costly lawsuits and settlement delays.
Smart contracts work on the If-Then premise so, to put in words of Jeff Garzik, one of the first Bitcoin Core developers:
“UPS can execute contracts that say, ‘If I receive cash on delivery at this location in a developing, emerging market, then this other [product], many, many links up the supply chain, will trigger a supplier creating a new item since the existing item was just delivered in that developing market.”
All too often, supply chains are hampered by paper-based systems, where forms have to pass through numerous channels for approval, which increases exposure to loss and fraud. The blockchain nullifies this by providing a secure, accessible digital version to all parties on the chain and automates tasks and payment.
There’s no doubt that we’re progressing from slothful pre-human vertebrates to super-smart robots. Think of a future where everything is automated. Google’s getting there with smartphones, smart glasses, and even smart cars. That’s where smart contracts help. One example is the self-autonomous or self-parking vehicles, where smart contracts could put into play a sort of ‘oracle’ that could detect who was at fault in a crash; the sensor or the driver, as well as countless other variables. Using smart contracts, an automobile insurance company could charge rates differently based on where, and under which, conditions customers are operating their vehicles.
You can get more money through smart contracts. Ordinarily, if you wanted to rent your apartment to someone, you’d need to pay a middleman such as Craigslist or a newspaper to advertise and then again you’d need to pay someone to confirm that the person paid rent and followed through. The ledger cuts your costs. All you do is pay via bitcoin and encode your contract on the ledger. Everyone sees, and you accomplish automatic fulfillment. Brokers, real estate agents, hard money lenders, and anyone associated with the property game can profit.
Personal health records could be encoded and stored on the blockchain with a private key which would grant access only to specific individuals. The same strategy could be used to ensure that research is conducted via HIPAA laws (in a secure and confidential way). Receipts of surgeries could be stored on a blockchain and automatically sent to insurance providers as proof-of-delivery. The ledger, too, could be used for general healthcare management, such as supervising drugs, regulation compliance, testing results, and managing healthcare supplies.
