In the Bitcoin network, nodes fulfill a very important role. You can imagine them as ‘guardians’, who are constantly monitoring the Bitcoin blockchain to distinguish legitimate Bitcoin transactions from non-legitimate ones. Their basic job is to prevent attempts to double-spend bitcoins that have already been spent elsewhere.

What is defined…


Most people familiar with cryptocurrencies know that a blockchain is a chain of transaction blocks tied together by cryptographic hashes. Many could also identify what a smart contract can do, based on an understanding of Ethereum. However, when it comes to more technical terminology, such as Virtual Machines, Turing-completeness, or…


A decentralized wallet means that the holder of the keys will be accorded access to the crypto wallet. It allows the holder to use the keys to send or receive cryptocurrency anywhere on the planet. Some people regard a decentralized wallet to be anonymous, but it is not. …


Introducing Ethereum 2.0

To ease some of the pressure, developers are turning to a concept called sharding that will create 64 new chains on the Ethereum network to further spread the volume. This will essentially take the massive amount of data currently being stored on Ethereum nodes and break it…


Optimistic Rollup is a layer 2 technology which scales Ethereum smart contracts and DApps up to 100–2000 transactions per second (TPS). Its major advantage over other solutions is the fact it enables turing-complete smart contracts on layer 2 using Optimistic Virtual Machine (OVM), reducing the cost of user transactions.

A blockchain bridge provides a connection that allows for the transfer of tokens or data between two different blockchain ecosystems.

A significant challenge of blockchains to date is their lack of interoperability. …


Even those who are not familiar with blockchain are likely to have heard about Bitcoin, the cryptocurrency and payment system that uses the technology. Another platform called Ethereum, that also uses blockchain, is predicted by some experts to overtake Bitcoin this year.

In late 2013, Vitalik Buterin was working on…


Axie Infinity:

A blockchain-based game called Axie Infinity has taken over the crypto space and is currently dominating the NFT world. But what is it exactly?

Axie Infinity, created by Sky Mavis back in 2018, is a turn-based RPG game that allows users to buy, sell, trade, breed, and battle cuddly digital…


What are Ethereum (ETH) and Ethereum Classic (ETC)?
Ethereum is a public, open-source software platform built to support smart contract functionality. The network uses Ether (ETH) as its currency to process transactions and provide computational power to developers. The network also allows developers to build decentralised smart contract applications on top…
