The exponential adoption of blockchain technology and smart contracts forces us to find new solutions to emerging scalability and efficiency challenges. One solution that has attracted attention in the Ethereum ecosystem is the zkEVM Rollup, a zero-knowledge (ZK) rollup designed to enhance the performance and security of smart contracts. Zero-knowledge rollup, or ZK-Rollup, is a … Read more

$821,000 Ethereum Value per Solidity Developer

Ethereum’s Total Value Locked (TVL) is $28,000,000,000 USD and Ethereum’s market cap is $193,000,000,000 USD. Based on my estimations below, there are at most 269,000 monthly active Solidity developers. Therefore, the Ethereum TVL per Solidity developer is more than $104,000, and the Ethereum market cap per Solidity developer is more than $717,000. So for all … Read more

I Created a React Decentralized App to Sell eBooks – Here’s How (4/4)

We completed a transaction in the last part, but the transaction data had yet to be seen. In this part, we will drive the smart contract data to the user interface. The user’s data and the transaction time will be displayed on the user interface. This is part 4 of our four-tutorial series on creating … Read more

I Created a React Decentralized App to Sell eBooks – Here’s How (3/4)

This is part 3 of our four-tutorial series on creating a decentralized web app to sell ebooks: πŸ‘‡ We will connect the front end with the smart contract in this part of the series. The interaction with the smart contract will be done using ether.js. Move to the app.js file inside the source folder. We … Read more

I Created a Counter Smart Contract with Ether.js — Here’s How

One of the presiding JavaScript libraries for interacting with the Ethereum blockchain is ether.js. The ether.js library, only 88 KB compressed in size, is remarkably smaller than the web3.js library. Because of that, web apps load more quickly if you use the ether.js API. This constantly improving library has already been popular among developers for … Read more
