Chainlink is a decentralized oracle network that connects smart contracts on blockchains with the real world. Using a system of nodes and operators, it is able to answer data requests from smart contracts by collecting data from multiple sources and reconciling it to provide a single reliable piece of information. For example, if a smart contract needs the current price of Bitcoin, it can request that data from Chainlink, which will look at several different reliable sources and provide an answer based on them.

In order for Chainlink to function, it is supported by LINK, its native token, which is used as compensation for the work Chainlink network operators do in providing smart contracts with requested data. …

In the cryptocurrency industry, mining means adding new blocks of data to a blockchain. Cryptocurrency miners have to find a solution to a complex mathematical problem before they can create a new block. They are then rewarded with newly-created coins of cryptocurrency.

When blockchains first emerged, miners could use ordinary desktop computers. But as blockchain’s popularity grew, the difficulty and cost of mining increased. Today, a single desktop computer is no longer enough and solo mining is not nearly as effective as it used to be. Most miners use enormous purpose-built systems and combine their computing power in mining pools.

Ethereum is a blockchain system that enables the creation and transfers of various kinds of tokens. These tokens have many uses and can represent currency, digital assets like IOUs, vouchers and more.

To make these tokens compatible with each other, the Ethereum community follows procedures specified by a technical document called ERC. ERC stands for Ethereum Request for Comments and it is usually equipped with a unique proposal ID number. This prescribes how tokens can be shared, exchanged or transferred to a crypto wallet. One of the best-known ERCs used for tokens is ERC-20.

ERC-20 ESSENTIALS

  • ERC-20 stands for Ethereum Request for Comments 20. …

The Ethereum blockchain exists on computers all across the world. Besides being the ledger for its own cryptocurrency, ether, one of the greatest perks of the Ethereum platform is its ability to run smart contracts.

Smart contracts are applications the functions of which can be executed only when their requirements are met. They help you exchange money, property, shares, assets, or anything else that is digitally representable. Since they’re based on the blockchain, smart contracts offer a completely transparent way of making transactions. At the same time, they cut the costs and services of a middleman.

SMART CONTRACT ESSENTIALS

  • Applications that can be called upon to be executed when certain conditions are met. …

A blockchain node is a device that runs the blockchain protocol software. Nodes connect to each other in a decentralized peer-to-peer network.

Full nodes ensure that all transactions and blocks follow the protocol rules. They continuously verify that everyone on the network adheres to the same rules. This ensures that the database is trustworthy and that the network stays honest.

For the sake of simplicity, this article will focus on Bitcoin nodes. Most blockchain networks use the same principles, so understanding Bitcoin nodes will give you an idea about how blockchain nodes work in general.

BLOCKCHAIN NODES ESSENTIALS

  • Broadcast transactions to the network (to all other nodes). …

To transfer cryptocurrencies like bitcoin, litecoin or ether, a fundamentally different infrastructure is needed from traditional payment systems.

The Bitcoin network is the first infrastructure to enable peer-to-peer transfers of digital money, putting the advantages of blockchain technology and public-key cryptography into practice.

Simply put, a cryptocurrency transaction is a transfer of information made between blockchain addresses. These transfers have to be signed with a private key that corresponds to its address. Signed transactions are broadcast to the network of nodes, active computers that follow a specific set of rules to validate transactions and blocks. …

Blockchains using proof of work are often referred to as immutable ledgers: everything written in such a blockchain is there to stay. It is impossible to alter or replace that information. But is it really impossible to enforce changes in a blockchain, to change the history of transactions and redistribute coins? The simple answer is: it’s not impossible, just so difficult that it is nearly so.

There are few digital systems that can compare to the success blockchain has achieved at maintaining the integrity of the information recorded on it. …
