Hashing in solidity

A cryptographic hash function is an algorithm that takes an arbitrary amount of data as input and produces the enciphered text of fixed size. Even a slight change in the input gives a completely different output.

Solidity - View & Pure functions

The view functions are read-only function, which ensures that state variables cannot be modified after calling them.

Public, Private & Permissioned Blockchains

Hlo Everyone

In this article we will discussed about different types of blockchains:

  • Public Blockchain
  • Private blockchain
  • Permissioned Blockchain

How to display internal ERC20 Token transfers in Truffle Tests?

In last post we discussed about ERC20 token: https://fifo.im/p/ttipy8x99xw0

In this post, we’ll explore how to use truffle-token-test-utils package to visualize token transfers in Truffle and OpenZeppelin tests.


The Ethereum Clients

As the Ethereum network is distributed and connected over the internet everybody can join the network by setting up a node and therewith participating in the network. To setup you own node on your computer you need an Ethereum client software.

The Ethereum Network

Before diving deeper into the concept of the Ethereum blockchain we first need to get an understanding of the Ethereum network itself which is essential to operate the blockchain.



How does IOTA work..?

Unlike other cryptocurrencies such as Bitcoin, IOTA is built on a distributed ledger technology that’s somewhat different from blockchain. IOTA uses a proprietary technology called the Tangle, which is a consensus algorithm that requires users to validate two transactions in order to complete their own IOTA transactions.

What is IOTA..?

IOTA is a smart contract platform designed to handle payments and other transactions between physical devices that are connected to the internet. MIOTA is a cryptocurrency token used by the IOTA platform to facilitate transactions.


The Ethereum Merge: Everything you need to know

The ETH merge refers to developers changing Ethereum’s consensus mechanism, the process the blockchain uses to ensure every transaction and new block added on the network is valid. Ethereum will move from an energy-intensive proof-of-work consensus mechanism to a more energy-efficient proof-of-stake one.


What is Infura

Infura is a kind of node storage (cluster). A set of tools that provides its services for integrating your application with the Ethereum network.
