FAQ About Chainlink (LINK)

• What Is Chainlink (LINK)?

  Chainlink was founded in 2017. It is an blockchain that allows smart contract to be universally interconnected. Chainlink, a decentralized oracle , allows blockchains and smart contracts to interact securely through a decentralized Oracle . This provides the off-chain data needed for complex smart contract to become dominant digital agreement.
  Chainlink Network's open-source community is made up of data providers, Node Operators, smart contract developers and auditors, among others. The company is focused on guaranteeing decentralized participation for node operators, users and researchers who want to contribute to the chainlink network.

• Is Chainlink (LINK) a good Investment?

  Investing in Chainlink (LINK) depends on various factors, including individual financial goals, risk tolerance, and market conditions. It's important to conduct thorough research and consider your own circumstances before making investment decisions.

• What is LINK Used For?

  The ChainLink network utilizes the LINK token** to pay ChainLink Node operators for the retrieval of data from off-chain data feeds, formatting of data into blockchain readable formats, off-chain computation, and uptime guarantees they provide as operators. In order for a smart contract on networks like Ethereum to use a ChainLink node, they will need to pay their chosen ChainLink Node Operator using LINK tokens, with prices being set by the node operator based on demand for the off-chain resource their ChainLink provides, and the supply of other similar resources. The LINK token is an ERC20 token, with the additional ERC223 “transfer and call” functionality of transfer(address,uint256,bytes), allowing tokens to be received and processed by contracts within a single transaction.

• What Are the LINK Technical Advancements

  To empower a broad range of next-generation smart contract applications and use cases, Chainlink 2.0 focuses on oracle technology advances in seven key areas.
  1. Hybrid smart contracts
  Hybrid smart contracts can be used to enhance the capabilities of smart contract by combining on-chain and offline computing resources.
  2. Scaling
  Decentralized oracle network performance must meet the requirements of high-performance Blockchains, Layer-2 solutions and Web2 systems.
  3. Abstracting away complexity
  Provide developers and users simple functionality, removing the need to understand complex protocols and system boundaries.
  4. Confidentiality
  Create high-integrity systems that combine the inherent transparency of blockchains with strong confidentiality protections to sensitive data and computations.
  5. Order fairness
  Support the transaction sequencing of transactions in a fair way for end users and prevent bots from front-running or extracting value by exploitative miners.
  6. Trust-minimization
  Decentralization, cryptographic assurances, and guardrails can be used to create a layer of reliable support for smart contracts, oracle-dependent software, and other systems.
  7. Cryptoeconomic security
  Make sure nodes of decentralized oracles networks are strongly motivated to act reliably and correctly even when faced with well-resourced opponents.

• How does Chainlink work?

  Chainlink is operated by a decentralized network of oracle nodes. These nodes collect data from external sources and validate it before relaying it to smart contracts. Smart contracts can interact with data outside of their native blockchain using this process. Chainlink is decentralized, which makes the data more secure and reliable. The network uses a staking system, which allows node operators to lock up their LINK Tokens for collateral. The collateral can be reduced when a node gives incorrect data. This encourages honesty and accuracy. Make sure nodes in decentralized Oracle networks are given strong incentives to act reliably and accurately, even when faced with well-resourced opponents.

• What's ChainLink Security Services?

  Thanks to the protocols we have just described in the previous section, ChainLink proposes to ensure availability and correctness in the face of up to f faulty oracles. Additionally, trusted hardware, as discussed in Section 6, is being actively considered as a secure approach toward protecting against corrupted oracles providing incorrect responses. Trusted hardware, however, may not provide definitive protection for three reasons. First, it will not be deployed in initial versions of the ChainLink network. Second, some users may not trust trusted hardware (see Appendix B for a discussion). Finally, trusted hardware cannot protect against node downtime, only against node misbehavior. Users will therefore wish to to ensure that they can choose the most reliable oracles and minimize the probability of USER-SC relying on > f faulty oracles. To this end, we propose the use of four key security services: a Validation System, a Reputation System, a Certification Service, and a Contract-Upgrade Service. All of these services may initially be run by one company or group interested in launching the ChainLink network, but are designed to operate strictly accordingly to ChainLink’s philosophy of decentralized design. ChainLink’s proposed security services cannot block oracle node participation or alter oracle responses. The first three services only provide ratings or guidance to users, while the Contract-Upgrade Service is entirely optional for users. Additionally, these services are designed to support independent providers, whose participation should be encouraged so that users will eventually have multiple security services among which to choose.

• What Is ChainLink Long-Term Technical Strategy?

  The long-term technical strategy for ChainLink proposed includes three key directions: Oracle confidentiality, infrastructure changes, and off-chain computation.

• What role does the LINK token play within the Chainliink ecosystem?

  The LINK token, which is a part of the Chainlink eco-system, serves various functions. The LINK token is used primarily as a non-monetary form of reward for services in the network. Chainlink node operator who provides data and information to smart contracts on the blockchain from sources off-blockchain receive LINK tokens in return for their contribution. Node operators determine the non-monetary rewards for their services based on market conditions and demand for data. Node operators also use LINK tokens within the network as a way to commit to the network. When matching nodes to requests for data, the amount of LINK that a node provides is taken into consideration. Requests may be fulfilled by nodes that provide more LINK. This system penalizes nodes that provide poor service by reducing the amount of LINK they receive. The LINK token is designed to ensure the integrity and reliability of the Chainlink eco-system. Chainlink is operated by a decentralized network of oracle nodes. These nodes collect data from external sources and validate it before relaying it to smart contracts. Smart contracts can interact with data outside of their native blockchain using this process. Chainlink is decentralized, which makes the data more secure and reliable. The network uses a staking system, which allows node operators to lock up their LINK Tokens for collateral. The collateral can be reduced when a node gives incorrect data.
