Decentralized finance (DeFi) took the world of crypto by storm in 2020. And, though the hype had cooled down somewhat by the end of last year, we are still seeing signs of its growing popularity now, well into 2021.

DeFi is all about utilizing  Blockchain  Blockchain Blockchain comprises a digital network of blocks with a comprehensive ledger of transactions made in a cryptocurrency such as Bitcoin or other altcoins.One of the signature features of blockchain is that it is maintained across more than one computer. The ledger can be public or private (permissioned.) In this sense, blockchain is immune to the manipulation of data making it not only open but verifiable. Because a blockchain is stored across a network of computers, it is very difficult to tamper with. The Evolution of BlockchainBlockchain was originally invented by an individual or group of people under the name of Satoshi Nakamoto in 2008. The purpose of blockchain was originally to serve as the public transaction ledger of Bitcoin, the world’s first cryptocurrency.In particular, bundles of transaction data, called “blocks”, are added to the ledger in a chronological fashion, forming a “chain.” These blocks include things like date, time, dollar amount, and (in some cases) the public addresses of the sender and the receiver.The computers responsible for upholding a blockchain network are called “nodes.” These nodes carry out the duties necessary to confirm the transactions and add them to the ledger. In exchange for their work, the nodes receive rewards in the form of crypto tokens.By storing data via a peer-to-peer network (P2P), blockchain controls for a wide range of risks that are traditionally inherent with data being held centrally.Of note, P2P blockchain networks lack centralized points of vulnerability. Consequently, hackers cannot exploit these networks via normalized means nor does the network possess a central failure point.In order to hack or alter a blockchain’s ledger, more than half of the nodes must be compromised. Looking ahead, blockchain technology is an area of extensive research across multiple industries, including financial services and payments, among others.

Read this Term solutions to provide conventional financial services. This is done via smart contracts, without government or corporate control, and without the need for intermediaries, which significantly shorten the time it takes to conduct operations.

This field is now subjected to great interest because the option of having blockchain-based alternatives to conventional banks or brokerages is gaining in value and popularity. The idea here is that DeFi, with a proper governance approach, can make  Payments  Payments One of the bases of mediums of exchange in the modern world, a payment constitutes the transfer of a legal currency or equivalent from one party in exchange for goods or services to another entity. The payments industry has become a fixture of modern commerce, though the players involved and means of exchange have dramatically shifted over time.In particular, a party making a payment is referred to as a payer, with the payee reflecting the individual or entity receiving the payment. Most commonly the basis of exchange involves fiat currency or legal tender, be it in the form of cash, credit or bank transfers, debit, or checks. While typically associated with cash transfers, payments can also be made in anything of perceived value, be it stock or bartering – though this is far more limited today than it has been in the past.The Largest Players in the Payments IndustryFor most individuals, the payments industry is dominated currently by card companies such as Visa or Mastercard, which facilitate the use of credit or debit expenditures. More recently, this industry has seen the rise of Peer-to-Peer (P2P) payments services, which have gained tremendous traction in Europe, the United States, and Asia, among other continents.One of the biggest parameters for payments is timing, which looms as a crucial element for execution. By this metric, consumer demand incentivizes technology that prioritizes the fastest payment execution.This can help explain the preference for debit and credit payments overtaking check or money orders, which in previous decades were much more commonly utilized. A multi-billion-dollar industry, the payments space has seen some of the most innovation and advances in recent years as companies look to push contactless technology with faster execution times.

The value of DeFi is continuing to skyrocket - recent statistics show that in February 2021 the total value locked in DeFi projects eclipsed $40 billion. For the sake of comparison, at the beginning of 2019, this figure was around $40 million. The difference speaks for itself.

That said, it is not as if the DeFi field holds no risks. High levels of volatility in this market make the impermanent loss a fairly common occurrence - when the price of a DeFi token goes down compared to its original value. Many projects have gone through this last year.

Another danger comes from hackers, who have increasingly targeted this field in 2020. And, in 2021 the most recent examples would be Yearn.Finance in February ($11 million lost) and DODO in March ($3.8 million lost).

Scams are an important thing to look out for. The open nature of DeFi has led to a great number of pump-and-dump schemes, fake giveaways, exit scams, etc. According to blockchain analytics company CipherTrace, exit scams, in particular, made up 99% of crypto fraud schemes in the second half of 2020, allowing criminals to get away with about $1.9 billion in stolen funds.

But even with all that said, people keep on believing in DeFi and the growth continues. We have observed that high-value clients, corporates and institutions are getting particularly interested in this sector as they want to invest major sums. The presence of such demand is integrated DeFi support, giving clients access to more financial tools of choice.

To sum up, it can only be said that DeFi could offer investors a very rewarding experience, but this can only happen if they approach decision-making with prudence.
