When you use bitcoin to buy something, it records the transaction on a blockchain, which is essentially a ledger or database whose entries can’t be modified or erased. Of course, that’s also true of traditional financial systems and currencies. Someone asking you to pay with a gift card or wire transfer is a red flag that you’re dealing with a scammer. “You have a private key, which is how you initiate transactions, and a public key, which is how someone identifies you in the market,” says Donovan. Ether is the cryptocurrency native to the Ethereum blockchain, but is also available for trading on other exchanges like Coinbase, Binance.US, Ninjatrader and Robinhood. Chainlink uses an oracle reputation system to aggregate and weight the data provided.

Second, the tokens can be used to govern the blockchain if the network uses a proof-of-stake (PoS) system. A PoS system — as opposed to a proof-of-work (PoW) one, which incorporates “mining” — can be fairly complicated, especially for crypto newcomers. For example, stablecoins are a type of cryptocurrency that try to maintain a steady and fixed exchange rate with another asset, such as the US dollar. They give token holders voting power in a corresponding crypto project. A cryptocurrency’s blockchain is a digital record of all the transactions involving that crypto. Copies of the blockchain are stored and maintained by computers around the world.

Chainlink News
Chainlink attempts to solve this problem by providing a decentralized oracle service. In short, an oracle is a piece of software that translates external data to a language that smart contracts can understand (and vice versa). If you’d like to read more about them, check out our article Blockchain Oracles Explained. Many traditional financial products like loans, payments, derivatives, asset equity, and more are being built on the blockchain using smart contracts to increase their security and transparency and reduce barriers to entry. The ETH/USD price oracle can then be used by a blockchain application to get the current price of ETH when being used as collateral to obtain a loan or to settle a prediction made about the future ETH price.

The current CoinMarketCap ranking is #15, with a live market cap of $8,052,337,681 USD. PoS protocols were created with the idea to battle the vast power consumption required by PoW systems. PoS models are becoming increasingly popular as they need less electrical power and are easily scalable.

Chainlink is the decentralized computing platform powering the verifiable web
Chainlink is the industry-standard Web3 services platform that has enabled trillions of dollars in transaction volume across DeFi, insurance, gaming, NFTs, and other major industries. With LINK staking, Chainlink intends to bring a new layer of “crypto economic” security to the oracle network. It will do this by giving ecosystem participants, including node operators and community members, the ability to increase the security of Chainlink’s oracle services by backing them with staked LINK tokens. As a decentralized network, Chainlink allows users to become node operators and earn revenue by running critical data infrastructure required for blockchains’ success. Chainlink’s LINK token is an ERC-677 token that inherits functionality from the ERC-20 token standard and allows token transfers to contain a data payload.
Due to the integration of off-chain data, Chainlink has attracted the attention of numerous trusted data providers, including Brave New Coin, Alpha Vantage and Huobi. Data providers can sell access to data directly to Chainlink, thus monetizing the information they have. Chainlink services are powered by decentralized oracle networks with a long track record of high availability, reliability, and data accuracy. However, blockchains can support many use cases beyond simply moving and recording money on a ledger.
This means not only pursuing more partnerships, but also advocating for more education, events, and relationships through their new Chainlink Commnity Advocate program. Node operators also stake on the network to ensure long-term commitment to the project. Similarly to Bitcoin’s cryptoeconomic model, Chainlink node operators are incentivized to act in a trustworthy manner instead of being malicious. Given the absence of a central intermediary, developers face the challenge of finding a way to provide smart contracts with the real-world data they ideally need to interface with in order to be able to execute more ambitious functions. This data can include eclectic information on matters as diverse as currency conversion rates, the weather, or even sports game scores. The Chainlink network is, in some ways, a complement to the Ethereum network and other blockchains.
It is in the data providers’ best interests to only offer up accurate information, as a negative reputation score will result in their removal from the network. All these network operations are backed by monetary incentives that reinforce honest behavior and consensus. By redundantly validating and storing transactions across a large decentralized network of financially incentivized participants, blockchains make it extremely expensive and impractical to manipulate the shared ledger. According to the ICO documentation, 35% of the total token supply will go towards node operators and the incentivization of the ecosystem. Lastly, the remaining 30% of the total token supply was directed towards the company for the continued development of the Chainlink ecosystem and network. The participation of community members in staking will further incentivize node operators to remain honest.
They’re often compared to general ledgers, part of traditional double-entry bookkeeping systems where each transaction leads to debit and credit in different sections of the books. A decentralized currency is a currency not issued by a government or financial institution. In fact, no single person, company, or government controls a crypto’s blockchain. Anyone with advanced technology skills and coding experience can create a cryptocurrency. Two of the key objectives to ensure security on the Chainlink network are distribution of data sources and distribution of oracles. Like all networks, Chainlink wants to add more people and operators in order to become more robust and valuable–increasing their network effects.
In 2014, he co-founded the Secure Asset Exchange, a company facilitating easy web access to a decentralized asset exchange. Miners use computers to run computations on complex mathematical puzzles based on transaction data. These systems generate millions or trillions of guesses per second as to what the solutions to these puzzles could be. These are hashes, alphanumeric codes randomized to identify a single, unique piece of data. “One way to avoid a scam is to invest in more well-established cryptocurrencies,” says Parisi.
Once a block is added it can’t be reversed or altered — which is why people describe blockchains as “immutable.” “On the blockchain, it would say I’m sending you one coin, and I now have one coin, and you have one coin.” The lack of a central authority can also make cryptocurrencies more secure. “It’s hack-proof because there’s no one central point of failure,” explains David Donovan, executive vice president at Publicis Sapient. Past performance is not a guarantee or predictor of future performance.
Participation in staking LINK tokens assists ecosystem members, including node operators and community participants, in securing the network and enabling them to earn rewards. Chainlink’s technology has proven to be one of the most important pillars of the DeFi and broader crypto ecosystem. While that does introduce risks onto Ethereum DeFi, trusted external data sources are one of the most important building blocks for a healthy on-chain ecosystem of products. As we’ve mentioned, Chainlink node operators can stake LINK as a way to offer a bid to the intended buyer of the data. The node operator that “wins” the bid must provide the information to the smart contract making the request.
Chainlink produces its own wallet software that is available for download on its website, which allows you to store Chainlink on your computer. Weiss Research, an investment research firm that rates cryptocurrencies, has given Chainlink an overall rating of “B”, a technology and adoption rating of “B+”, and a market performance rating of “D+”. Purchasers select the data they want and providers bid to provide that data. Providers must commit a stake of LINK tokens when they make a bid, which can be taken away if they misbehave. Once providers are selected, it is their job to bring the correct answers on chain. The LINK token, central to Chainlink’s functionality, incentivises oracle accuracy, secures the system, and facilitates various transactions within the ecosystem.
While PoW has proven itself a reliable consensus mechanism, Ethereum and all other ERC-20 tokens have been growing rapidly and setting the trend in the space. During the initial coin offering (ICO) for LINK in September 2017, Chainlink announced a total and maximum supply of 1,000,000,000 LINK tokens. The current supply is about 453,509,553 LINK tokens, or about 45% of the total supply, as of end-September 2021. The Chainlink price at ICO was $0.11 and a total of 350 million LINK tokens were sold. This represents an over 200X from the ICO price to Chainlink price today. The proof-of-stake mechanism rewards network participants for placing a freeze on the ETH they “stake” or put up as collateral for the chance to earn rewards.

What makes this process powerful is how Chainlink can validate data from multiple sources. Due to an internal reputation system, Chainlink can determine with a relatively high accuracy which sources are trustworthy.
If a single, centralized oracle is responsible for inputting the data used to trigger the smart contract, then that oracle has complete control over the smart contract’s outcome. This introduces a serious point of failure known as the oracle problem, which puts the entire smart contract at risk. Chainlink was created by Sergey Nazarov and Steve Ellis, who authored a 2017 white paper with Ari Juels. LINK is an ERC-20 token, meaning that it is compatible with other currencies and smart contracts supported by the Ethereum platform.
This can greatly increase the accuracy of the results and protect smart contracts from all sorts of attacks. Instead, it integrates with multiple blockchains simultaneously, providing them all with up-to-date information streams. Chainlink purchases information from many data providers, which it then streams directly to blockchains.

Many people may be inclined to think that Chainlink can solve all of these problems – that may not be correct. Despite projects such as Synthetix, Aave, and others all relying on Chainlink’s technology, new types of risks are also introduced. If too many platforms rely on the same oracle service, they will all face outages if Chainlink suddenly stops working as intended. This data, as hinted at, is diverse and can range from price feeds, supply chain management data, temperatures relayed from a smart sensor, scores from a football game – anything that is relevant to the given blockchain’s purpose.
