What is decentralised finance?

Dezy Learn is here to break down both decentralised and traditional finance basics so that you are able to make informed decisions on your money.

Decentralised finance, or DeFi is an emerging field built on decentralised and distributed technologies. The aim of DeFi would be to remove third parties (ie. banks) from financial transactions and the fees that they charge.

What is a blockchain?
Blockchains are immutable and distributed ledgers. This means that a network is now able to transact with each other trustlessly and permissionlessly.

What does blockchain have to do with decentralised finance?
Let us break it down for you. Imagine you are on an e-commerce website. You see an item you like and add it to your cart, clicking check-out. From you entering your card details to your funds being remitted into the merchants’ bank account, it would probably have touched several financial institutions and banks.

Why is this the case? Old financial systems are hardly interoperable and have been band-aided together. This leads to huge inefficiencies. Transactions become more expensive, and you can barely earn interest with savings accounts in banks these days.

With a distributed ledger, you are now able to directly make a transaction to the merchant without needing an intermediary like Paypal or Visa. Wait a minute… what if you end up sending this seller money and never receive your product? Would you have any recourse? This is the main reasons for intermediaries like PayPal existing in the first place - to bring trust to the network and “mediate” any disputes. So who deals with this in the case of distributed ledger technologies?

Enter the smart contract.

What are smart contracts?

Smart contracts place logic on top of a blockchain that are automatically triggered. If we continue on with the above scenario, you would send your funds into an escrow, that would release funds to the seller upon your receipt of your item from the seller.

Where blockchains allowed for peer to peer payments without intermediaries, smart contracts then opened up a whole new world of products by allowing for programmable money. By introducing “if-this-then-that” logic onto a blockchain, a smart contract allowed for reimagining of financial instruments and legal structures. 

Are smart contracts and blockchains safe?

The cryptocurrency industry comes with risks. Smart contracts run the risks of being hacked, and funds can be lost in this manner. There are several things you can do to protect your funds when engaging in decentralised finance strategies:

  • Diversification
    Don’t put all your eggs in one basket. By diversifying your strategy across a range of different decentralised finance protocols, you do not have a central point of faliure

  • Insurance
    You can purchase decentralised finance native insurance on your DeFi strategies. InsurAce and Nexus Mutual are both insurers that are native to the cryptocurrency industry.

  • Security
    How do you know if the smart contract you are interacting with is safe? It is important to do research in the case of anything you are new to. One of the signals that a smart contract is safe is that it has undergone a security audit.

    What is a security audit? We dive deeper here. But TL;DR - a security audit means that the protocol has undergone a 3rd party audit of their smart contract code. While this is not a 100% guarantee of safety, it is an indicator that this is a safer strategy than an unaudited protocol. 



In summary, decentralized finance or DeFi, is an emerging financial technology that would theoretically simplify the way money, financial products, and financial services are managed. DeFi relies on blockchain technology and smart contracts which enables transactions between distributed corporate ledgers and secure digital wallets. This makes transactions almost instantaneous, and cheaper.
