Why Build DApps on Cardano Blockchain

Cardano is a blockchain platform that works on the proof-of-stake, it is developed by evidence-based methods. Charles Hoskinson is an American entrepreneur who is a co-founder of the blockchain engineering company Input Output which was later on named Cardano and was a co-founder of the Ethereum blockchain platform earlier. It was introduced in 2015, as an open-source blockchain platform. Basically, it facilitates peer-to-peer transactions with its internal cryptocurrency that is ADA.

 

Cardano blockchain’s native cryptocurrency is ADA — which can be bought or sold via exchanges like Coinbase. These days ADA can be used to store value, send and receive payments, and for staking and paying transaction fees on the Cardano network. It employs a consensus mechanism called Ouroboros. It opposes the mechanisms used in the energy-intensive proof-of-work system, currently found in blockchains like Bitcoin and Ethereum. The latter is working on employing a proof-of-stake system via the ETH2 upgrade.

 

The code on Cardano is written in Rust, though the project will support other programming languages such as C and Javascript, offering the potential to greatly expand the worldwide Cardano community. 

 

There are two layers of Cardano 

 

1) Cardano Settlement Layer (CSL)

 

2) Cardano Computation Layer (CCL)

 

The first Layer is intended to manage the transfer of value (or cash) between sender and receiver. We can say the Cardano Settlement Layer serves as the routing layer for all control layers and systems while the second layer enables Cardano to imitate the Rootstock smart contract platform from the Bitcoin ecosystem, i.e. the RSK blockchain. The rationale for CCL’s deployment is its capacity to assist in scale customized protocols over time. This necessitates integrating dedicated hardware modules (HSM) into the protocol stack as technology develops.

 

Why Cardano should be used for developing an NFT Marketplace?

 

*) NFT Marketplace generally slows down when traffic increases over time, whereas Cardano offers excellent scalability by addressing traffic and data management challenges.

 

*) It is extremely energy efficient because of its POS consensus method, allowing fast transactions at reasonable rates.

 

*) It minimizes the bandwidth need of each node by separating the main network into separate subnetworks.

 

*) It employs strategies such as pruning, compression, and segmentation to efficiently address data storage difficulties.

A Developer Guide to Understanding MetaMask Wallet

This article covers the basics of the MetaMask wallet and provides basic code to connect to MetaMask using web3 installation in Ethereum blockchain development.

 

MetaMask Crypto Wallet 

 

MetaMask is a cryptocurrency wallet that allows users to store ERC-20 tokens and Ether. It enables users to make transactions to any Ethereum address. It is available as a browser extension as well as a mobile app, MetaMask equips us with a key vault, secure login, token wallet, and token exchange—everything we need to manage our digital assets. 

 

MetaMask is being used hugely, it becomes much easier to send Ether here and there. MetaMask has integrated with hardware wallets like Trezor and Ledger, users can use the service while keeping their crypto on a hardware wallet.

Installing MetaMask

 

Installing MetaMask on the browser is quite an easy job to do and using it is easier than installing it because it keeps things quite organized, and is reliable as well. MetaMask gives an easy access point for the growing dApp (decentralized application) space.

 

One of the key reasons MetaMask is popular among new and existing crypto users is its interoperability with virtually all Ethereum-based platforms. MetaMask allows users to connect to more than 3,600 different decentralized applications and Web 3 services. As crypto is getting familiar among the crowd, Metamask has provided easy maintenance of the crypto.

 

Basic code to connect to MetaMask using web3:

 

'''
const connect = async() => {
    await window.ethereum.enable();
    window.web3 = new Web3(window.ethereum);
    window.web3.eth.requestAccounts().then(console.log(""));
};

 

Isn't it quite simple to connect with Metamask to your dapps, managing other stuff of Metamask for the dApps is also easy as we connect it.

Summing Up

 

Managing Metamask in the dApp can be done using different libraries like Web3, EtherJS, etc., so from here, we can analyze that it is rich from a library perspective. These days MetaMask is an important tool to learn if we want to deal with cryptocurrency. MetaMask stores the information locally. So, in case we switch browsers or machines, one can restore his/her MetaMask wallet with the secret recovery phrase. Explore MetaMask, and manage crypto easily.
