Discreet Log Contracts vs. EVM Oracle Networks: Two Visions for Trustless Finance
The Oracle Problem: Where Every Blockchain Hits a Wall A blockchain is, by design, a closed system. It can verify its own state with mathematical certainty – whether a transaction was signed correctly, whether a UTXO exists, whether a smart contract condition was met. What it cannot do natively is reach out and verify the […]

The zkEVM Race: Ethereum’s Most Difficult Engineering Problem
Every blockchain faces the same uncomfortable question eventually: what happens when more people want to use it than it can handle? For Ethereum, that question stopped being theoretical years ago. At peak congestion, a simple token swap can cost more in gas fees than the tokens themselves are worth. The network processes roughly 15 transactions […]
The Hidden Threats in Code Review Requests: A Cautionary Tale for Developers
As developers, we’re often approached to troubleshoot or optimize projects. While most requests are legitimate, sometimes they conceal malicious intent. Recently, we’ve been encountering situations that underscore the importance of vigilance in our field. Here’s a detailed account of what happened in one of the requests, how we uncovered the threat, and the lessons we […]
Real-World Assets and the Future of DeFi
Real-world assets are blockchain-based digital tokens that represent physical and traditional financial assets. The first wave of decentralized finance (DeFi) was a demonstration of the power of blockchain technology to create a new more efficient financial system. It was a sort of playground for developers and entrepreneurs to push the boundaries of the status quo […]
Navigating Upgradable Solidity Smart Contracts: A Practical Guide
In the ever-evolving landscape of blockchain technology, the concept of upgradeable smart contracts has emerged as a crucial tool for developers seeking to adapt and innovate over time. Historically, smart contracts were often viewed as immutable entities, where any modification required the deployment of an entirely new contract, often resulting in cumbersome migrations and potential […]
Overview of the Ethereum Rollup Ecosystem
Ethereum’s blockchain scalability problem is well known and the focus of much research and development. The network can only process a few dozen transactions per second, which is not enough for mass adoption. Not to mention that the network is highly congested and transaction fees are extremely high. The community has been working on solutions […]
The modern stack for Ethereum dApps
The advancments in the blockchain ecosystem are happening at a rapid pace. As people say 1 year in crypto is like 10 years in the real world. The same is true for the technology stack that is used to build regular web applications which in fact also sets the standard for the user experience and […]
