With cryptocurrencies, blockchain, NFTs, and the whole crypto-space, in general, being the latest hype, one reckons it might be useful to learn what some of it means and how it works.

Generally saying the blockchain is the network on which you make transactions ie. where you send money, only instead of sending USD or any other Fiat currency, you’ll be sending cryptocurrency.

Before mentioning DeFi and DeFi staking, let’s cover some crypto first!

Cryptocurrency

Simply said, it is a digital currency in which transactions are verified and maintained on a decentralized system.

To call something a cryptocurrency, there are some criteria it has to first fulfill.

What makes a currency crypto
1. It’s a digital asset
2. Transactions are verified and maintained on a decentralized system
3. It must not rely on a centralized authority
4. Cryptography-secured transactions
5. It has a limited supply

  • The last one might not be universal to all, as there are currencies that do not have limited supply, but these are based on some more advanced terms.
  • Regarding limited supply itself — cryptocurrencies heavily rely on mathematics, by which limited supply was made possible. This practically renders it scarce as let’s say gold, unlike Fiat currencies.

Btw. Fiat currency— is a currency that’s determined by an authority; or government, and isn’t backed or representative of another asset or financial instrument such as gold.

Both USD and EUR are Fiat currencies.

Blockchain

— noun
a system in which a record of transactions made in bitcoin or another cryptocurrency are maintained across several computers that are linked in a peer-to-peer network.

As mentioned, it’s a network, and it’s made out of peers connected to each other — managing all the transactions.

Possibly, the single most important note is that; blockchain, the network and all of its peers, stores digital information, and transactions, distributes them and allows no editing of that information.

That’s achieved by having all the peers track all the transactions, and simply, even if you — a single peer — would try to edit an old transaction (ie. Joe sent you $10, but you change that to $10.000), that edit would simply be denied by the network, because the network won’t trust your single-peer information.

This is why the decentralized networks are also called “trustless”, meaning there’s no single authority to be trusted, but the network as a whole.

DeFi

DeFi — Decentralized Finance is just Finance but on the Blockchain. It is an instrument based on the distributed network and cryptocurrencies and, the most important part, it’s a technology that does not rely on centralized authorities or intermediaries.

With DeFi Finance, there’s no need for brokerages, exchanges, and banks.

If finance is the science behind managing money and funds, DeFi is the same
on the blockchain.

Now, to the interesting part…

DeFi Staking

Decentralized Finance Staking, is the product of DeFi, altogether with cryptocurrencies and blockchain.

In the purest form, it is locking up an amount of money ie. crypto currency for a specified period of time. This is equivalent to locking your Fiat on your Savings Account in your bank.

The big difference is that individuals who keep their money in the bank, lose up on a lot of interests. Other options of traditional finance are, High-Yield savings accounts, Money Market Funds, Bonds, etc. but traditional approaches depend a lot on a centralized authority.

With DeFi staking, by locking your crypto you become a validator in the network — or better said in the Proof-of-stake.

Many blockchains are based on Proof-of-stake, meaning in simple terms, all the transactions validates in the peer-to-peer network

How does this actually work?
Proof-of-stake networks are too complex to be explained in a few paragraphs; essentially it is staking your cryptocurrency in order to validate other transactions. This concept heavily relies on cryptography and mathematics, but simply said — by staking your crypto, you will be generating a transaction which in turn will form a block with other transactions. Once a block of transactions is complete, it gets validated.

This is also the reason why you are getting more interest the larger amount you stake ie. the blocks are easier to complete.

With staking, individuals are helping validate the network and improving it in that way — thus are getting rewarded with more cryptocurrency. There’s nobody to hand that reward except the network itself, and the mathematical algorithms that are the actual implementations of the blockchain.

Traditional interests you might get with locking and saving your money in the bank, are not remotely comparable to DeFi staking.

To simply illustrate the difference — imagine you putting money in a centralized authority ie. the bank. You earn small interest, and the central authority makes much more with it, let’s say by just lending it to others. With DeFi staking, you are now in the role of that central authority, together with many other peers.

Takeaway

This, possibly most layman's idea shows how cryptocurrencies benefit individuals and cut out the central authorities and intermediaries.

When compared to traditional low-interest approaches or riskier so-called high-yield approaches — the DeFi benefits for the individuals are drastic:

  • High interests — passive income that you can actually benefit from
  • It’s simple to get started (often simpler than with complex banking offerings)
  • It’s highly secure — with the nature of secure decentralized blockchains and cryptocurrencies
