4 Ways to Use Smart Contracts


Hello world, Siraj here! Let’s talk about 4 ways to use Smart Contracts.

A smart contract is just a piece of code that is stored on a blockchain instead of a server

That means no one can alter or delete it since blockchains aren’t controlled by anyone.

It enables people to do business with strangers without the need to trust a third party.

The first way to use it is to bring voting online. The US government has never brought voting online because

of the security risks involved. If they stored everyone’s vote on a server, that server could easily be hacked.

and votes altered. If only there was some kind of system that could securely and pseudonymously store votes

online. Oh right, the blockchain. To do this, an engineer could create a smart contract and push it to the

blockchain. A smart contract would then get an address. Citizens could then just send a transaction to that

address with their encoded vote and SSN. The contract would then verify that the citizen had never voted

before and then store it. Because this code runs on the blockchain, a hacker would have to have more

computational power than the 500 fastest supercomputers on the planet combined to break

the system. Ain’t nobody got that much computing power!

Once a government implements this, voter turnout will skyrocket. Voting would finally become just another app

on our phone. No having to wait in line at some paper ballot booth a 30 minute drive away.

Millennials would actually vote. This would fundamentally improve the quality of the politicians we

elect. The second way is to increase spending transparency. Think about all the cases of government

corruption or evil corporate dealings. All of them, every single one, has to do with money.

Stealing money, spending money on personal interests, giving and taking money from shady businesses.

the list goes on. With smart contracts, we as citizens of a nation or shareholders in a company

can demand that all spending happen on the blockchain. Smart contracts can be instituted to route money as we

see fit. So for example, let’s say a politician promises to increase spending on healthcare for their state

if there is a smart contract that will route money sent to it every time to 20 hospitals and 10 insurance companies

the public can audit it. Since all transactions are public on the blockchain’s ledger and verified to be unaltered

by cryptography. The more companies and governments that institute this kind of transparency

The more those who don’t will be pressured to do so. It’ll slowly become the norm.

The third way is to increase autonomy. As our species has progressed we’ve automated more and more

We’ve offloaded more and more work to our machines. This trend will continue as our machines get better

Smart contracts bring us one step closer to full artificial intelligence. Take ride sharing for example. Uber

is a software app run by humans. Soon, Uber will implement self driving cars so it won’t need drivers.

But with smart contracts, Uber could become even more autonomous. Even more independent of humans.

A self driving car could live as an independent entity. Picking up passengers, paying for its own repairs, filling

its own gas, parking itself, coordinating with other cars. If these tasks were all smart contracts that the car

communicated with, it wouldn’t need humans at all. Instead of humans having to run the logistics and

plumbing of the Uber network, they could focus on more fun, creative pursuits.

the 4th way is to create smart property. Smart property is an object who’s ownership is verified by the blockchain

Traditionally we use humans to verify these things. Like, a stranger can’t rent out your apartment on airbnb

because airbnb has verified that it’s yours. But with smart contracts, you wouldn’t even need airbnb.

to rent out your place. You could create a digital token that would represent your apartment

and then a smart contract that said something like if you send money to this address, transfer the ownership token

to the sender for X amount of time. And because there’s no middleman to take a cut, you get more money

for renting out your place. This can be applied to everything from patents, to cars to fridges.

anything with internet communication capability. The internet of things!
