Comprare Chainlink

Chainlink (LINK) is a decentralized network of oracles, meaning "nodes" in this context, which focuses on making external data usable for smart contracts. Smart contracts cannot access data themselves now that the underlying blockchains cannot support communication with external systems because of their underlying consensus protocols. As a result, smart contracts cannot always be executed, for example when external data is required for the implementation of the agreement. Chainlink wishes to change this through its decentralized network of oracles.

The objective of Chainlink is to make external data (off-chain) usable for smart contracts (on-chain) and as such Chainlink has the following two important components:

1. On-Chain functions
   The first component of Chainlink consists of smart contracts that run on the Ethereum Blockchain. These smart contracts relate to the processing of external data from parties who want to use the oracle services. The smart contracts ensure that the requested external data is matched with the correct oracles.
2. Off-Chain fuctions
   The second component of Chainlink consists of oracle nodes which are connected to the Ethereum Blockchain. The oracle nodes are responsible for collecting the external data as requested in the smart contracts. After retrieving the relevant data, this is processed by the oracle nodes and made applicable for the smart contracts on the Ethereum Blockchain. In exchange for this work, the Oracles Link, the token belonging to Chainlink.

You need a wallet in order to store and use Chainlink. There are several options for saving and using Chainlink.

Hosted Wallet
Hosted wallets are wallets where the access keys to your Chainlink are managed by a third party such as Bitvavo. Access to your account is protected by a password, and possibly other advanced security methods. Once you are logged in, you can easily and conveniently manage your Chainlink online. Bitvavo offers standard hosted wallets for all digital assets that are offered on the platform. Click here for more information about how Bitvavo saves your digital assets as securely as possible.

Software wallet
A software wallet is a program installed on your computer or any other desired device in order to use and manage your Chainlink. By using a software wallet, you have full control over your "private keys" (and therefore your Chainlink), so you are not dependent on third parties such as Bitvavo. The software wallet simplifies the process of accessing your Chainlink. The risk is that if malicious parties have access to your device, your private keys (and therefore your Chainlink) can be stolen.

Hardware wallet
A hardware wallet is a physical device on which you can store your Chainlink offline. It is one of the safest ways to store your Chainlink, because the private keys are stored on a seperate, offline, device. Access to this device is often protected by a password. In that respect, a hardware wallet can be compared to a safe in which your Chainlink are stored.

You can use a hosted wallet, as offered by Bitvavo, to easily store, send and receive Chainlink. However, you are, just like at a bank, dependent on a third party (Bitvavo) for storing your Chainlink.

One of the advantages of Chainlink is that you can send, receive and store your own digital assets without the relying on third parties. You do this by sending your Chainlink, from your Bitvavo wallet, to your own software or hardware wallet.
