Investment - What is Decentralized Finance ( DeFi) ?
Imagine having the ability to send money straight from your bank account to another person's bank account using fiat currency, which is money that has been issued by the government, all without the need of a bank or the supporting infrastructure of the banking industry. Decentralized finance, or DeFi, is based on the idea of not depending on centralized functions.
Centralized versus Decentralized Finance: What's the Difference?
To trade, record, and manage financial transactions, traditional finance relies on centralized functions. This established quo is being challenged by Decentralised Finance (DeFi). This phrase refers to financial initiatives and apps that leverage blockchain technology to offer a decentralized substitute for conventional financial services.
An Overview of Blockchain
The first cryptocurrency, Bitcoin, was announced in 2008 by Satoshi Nakamoto in a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System," even though the concept of the blockchain came first. Unlike fiat currencies, which are issued by a central government and include the US dollar, the euro, and the Chinese yuan, cryptocurrency, also referred to as digital money, is an electronic currency made of encrypted data that serves as a medium of exchange.
A distributed blockchain based on hashing and proof of work (POW) is used by Bitcoin to create an unchangeable record of all transactions. Let's examine each of these points in more detail. The flashcards that follow go into detail into ledgers, blockchains, and hash-based proof of work.
A program has transformed any text, audio, or video data for a transaction into a distinct, encrypted output that functions as a fingerprint of the original data. This is known as hash-based proof of work. A distinct hash is generated when any component of the input data is altered. The function of proof of work efforts is to verify and examine the veracity of newly added transactions to a blockchain.
Again using hash-based proof of work, blockchains are composed of blocks that are connected by hashing, and anybody can access their distributed network. In a peer-to-peer network, a blockchain records transactions and keeps track of them through independent computers known as nodes.
The transactions are recorded by the nodes of the blockchain, which functions as a distributed ledger—a database that is shared by numerous parties and not under the control of a single institution. A financial institution's traditional, centralised ledger is in contrast to a distributed ledger.
Though conceptually straightforward, putting this new database design into practice required overcoming formidable technological obstacles that had baffled computer scientists since the 1980s. How do you ensure that all versions of the same database are identical, updated synchronously, and represent only legitimate transactions when there are a million copies of it scattered over a million machines and no one is in control? Stated differently, what are the reliable methods for reaching a consensus on what is true and accurate?
The true innovation of blockchains lies in its ability to solve this conundrum: generating timely, bad-actor-proof consensus among all copies of a distributed, decentralized database.
What Are the Tasks of Miners?
An individual who validates transactions in a blockchain and receives payment for their computational efforts is known as a miner. The proof of work is a computational challenge that miners strive to solve first. Miners increase the amount of cryptocurrency available by adding new blocks.
Proof of stake serves as an alternative to proof of work. A stake is made by participants in a proof of stake paradigm in order to act as validators. The platform then gives a validator the task of proving the following block at random. Once they have resolved the computational issue, the other validators offer agreement. With this method, the competition that comes with proof of work is eliminated, as miners are no longer competing with one another to solve the next block's puzzle and earn rewards. The proof of stake significantly reduces energy usage.
Permissionless blockchains are those that are publicly accessible, like Bitcoin. Anyone can transact on it, become a miner, or run a node using the publicly available code. Blockchains aren't all public, though. There are two types of blockchains: consortium blockchains, which are comprised of the companies in the delivery chain and may be suitable when utilizing blockchain technology to create a logistics platform. Private blockchains are accessible, with membership restricted to invitations only.
Blockchain Technology and Stablecoins
Most likely, the most well-known cryptocurrency is Bitcoin. There are more than 10,000 cryptocurrencies, so choosing one to hold or invest in requires research and knowledge of the industry.
Stablecoins is a term used to describe some of these currencies. A cryptocurrency that is tied to another asset or group of assets is known as a stablecoin. They are called fiat-collateralized because they are linked to a fiat currency, such the US dollar. The value of the underlying asset—in this case, the fiat currency—variates with their actual worth.
In conventional finance, the US dollar and the majority of fiat currencies are linked to gold or another underlying asset.
Because of the way they are pegged, the way their governance is set up, or the makeup of their reserve assets, stablecoins do not necessarily trade exactly in line with their pegged asset.
Values of cryptocurrencies can fluctuate greatly; stablecoins are no exception. What causes this fluctuation?
Similar to any other asset, demand and supply—both of which are finite—have an impact on value.
The deals made by major companies have an impact on market values.
Speculation fluctuates, impacted by media and economic factors.
Ethereum
Ethereum is a public blockchain, just like Bitcoin, that supports the majority of DeFi protocols and tiny programs known as smart contracts. While Bitcoin is primarily a transaction blockchain that uses proof of work to offer the framework for value transfers in the form of Bitcoin, Ethereum is also a public blockchain. The name of its native cryptocurrency is Ether.
On the Ethereum blockchain, every transaction has an associated cost. Gas is the name of this transaction cost; it is automatically subtracted from the account of the person who initiated the transaction and is paid in ether. A solitary transaction may entail numerous processes and be highly intricate. The transaction ends and everything returns to its initial state if there is not enough Ether in the account to cover each phase of the transaction. The person who started the transaction but ran out of gas will forfeit the gas they have already used to finish the transaction, but they will receive nothing in return. All blockchains, including the Bitcoin blockchain, charge for transactions, but Ethereum has its own currency called gas.
Smart Contract
A smart contract is a type of transaction protocol used in blockchain networks that automatically logs, manages, and carries out procedures or transactions on behalf of the parties involved.
These contracts can be directly interacted with by Ethereum network users, eliminating all counterparty risk. More transactional possibilities are created by these little programs than only value transfers. In order to interact with these smart contracts, users must have an Ethereum network-compatible cryptocurrency wallet, which is effectively a password-protected place to access cryptocurrency. In order to transact and pay the gas price, users also require Ether.
After discussing the idea of smart contracts, let's discuss several key positions in the DeFi ecosystem: automated market makers, keepers, and oracles. To find out more about each of these DeFi principles, select the corresponding tabs.
ORACLES
Any data source that reports information outside of the blockchain is referred to as an oracle in the context of smart contract platforms. For instance, market data may be provided by an oracle, and smart contracts may then act in response to that data. While certain DeFi protocols might rely on a third-party oracle like Chainlink, many others host their own oracle.
KEEPERS
A lot of DeFi protocols depend too much on collateralization. However, what occurs if the collateral loses value and is no longer worth the requisite sum? In conventional finance, a broker would want more margin in order to increase the collateral's value, but brokers do not exist in DeFi. Rather, unaffiliated entities known as keepers oversee collateralized holdings and eliminate those that lose their collateralization. The smart contract's integrity is safeguarded by this step. Reward is given to keepers for their efforts.
AUTOMATED MARKET MARKERS
A market maker, also known as a liquidity provider, quotes the bid-ask spread—the price at which an item is bought and sold—in conventional finance. The market maker will run out of the asset and will need to purchase more if more customers purchase from them than sell to them. As a result, they would alter the price they quote to make their selling price appear less appealing and their bid appear more appealing. Their price reacts to market demand in this way. An automated market maker (AMM) is a tool for trading in decentralized exchanges that uses algorithms to price assets in a decentralized system.
Risks
Many of the issues with traditional finance—such as centralized control, restricted access, inefficiency, lack of interoperability, and opacity—are resolved by blockchain-based protocols. DeFi also gets rid of some of the counterparty risk and other concerns that come with traditional finance. However, there are hazards associated with DeFi as well, some of which are specific to the platform and smart contracts.
Technology Risks
A smart contract is a piece of code that has two potential risks: -logic errors in the code; -contracts being utilized in a way that the developers did not anticipate, which could lead to poor administration and economic exploitation.
Oracle Risks
Oracles are vulnerable to hacking, and the data they receive is modified.
Keeper Danger
Users can transfer bitcoin in the blockchain and access their crypto assets through a crypto wallet, which functions similarly to a bank account. Wallets can be hosted through an app, with the third party managing the digital account as the host. Certain wallets enable users to carry out additional blockchain transactions.
A private key is needed to open wallets and carry out transactions. A private key can be compared to a very complex password.These keys are vulnerable to hackers if they are maintained online. A person's wallet may be completely emptied of all assets with no possibility of recovery if private keys are stolen.
Additional RIsks
Other dangers exist as well; not all of them are exclusive to DeFi. Since regulators are keeping a close eye on the cryptocurrency sector, regulatory risk is significant.
Among the regulatory measures they take into account are the determination that cryptocurrency exchanges have to register and that some cryptocurrency assets should be governed by the same regulations as securities. Regulation will increase rather than decrease in the future.
Ultimately, it is critical to understand that the cryptocurrency industry operates online and is vulnerable to hacking and domain name system (DNS) attacks, just like any other internet industry. Additionally, a lot of successful thefts have happened as a result of account holders being convinced to divulge their passwords.
