The tech industry is changing fast—but not in the way most people think. By 2026, success in engineering won’t be about chasing the newest tools or stacking buzzwords on a résumé. It will be about depth, ownership, and usefulness. Here’s a grounded l...
1. Server Streaming RPC: Description: In this type of RPC, the client sends a single request to the server, and the server responds with a stream of messages. The client reads from this stream of responses until there are no more messages. Use Case...

The blockchain is great, likewise, it's growing ecosystem. With bitcoin being the first generation of the blockchain, we've experienced speedy growth which has given birth to more decentralized solutions like the Ethereum blockchain. With the birth of Ethereum comes the "Smart Contract" that runs on the Enthereum Virtual Machine where programs are executed in exchange for gas fees.
For the short while learning about blockchain technology, there's been this argument attached to the Ethereums Smart Contract, are they really smart? For total newbies with little or no knowledge about this technology, you would really think they are smart as the name implies. The ultimate goal of this article is to express my opinions and ideas about why the term 'Smart' should be replaced.
A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. The code controls the execution, and transactions are trackable and irreversible. They are written in a programming language called solidity.
As a form of encouragement, here are a few interesting things about the smart contract and its associated language.
It's about time to talk about why the ethereum team should have a second thought about renaming "Smart Contract". These points of mine are with respect to the solidity language because yeah, it's totally behind birthing any smart Contracts. These points are not particularly pitfalls of the language but more of a few things that are left out and implemented wrong ( to me ) as listed below.
There are a few weird things about using strings while working with solidity, particularly comparing a string with other data types.
if (username == "deepak") //error: operator == is not compatible with string ?
{
return true;
}
Like why can't I do it like that?? 😔😔
function compareStrings(string memory a, string memory b) public view returns (bool) {
return (keccak256(abi.encodePacked((a))) == keccak256(abi.encodePacked((b))));
}
It's the stress for me 😶 . Not so smart
For popular languages like javascript, it ships with the console.log debugging feature. There's probably a reason behind this, most likely behind the architecture of the technology. The absence of something similar to this makes it less smart. 🏃♀️🏃♀️
Honestly, taking extra cash for transaction calls is regular with the Ethereum Blockchain. Saving me some funds would be a smarter move yunno.
With these few points of mine, I hope to convince and not confuse the Ethereum Community to re-consider renaming smart Contracts to something we can all relate too without doubts.
