What Is Sybil Resistance in Blockchain? Examples and Preventions
A Sybil attack occurs when a malicious actor floods a blockchain network with multiple fake identities (nodes) to gain disproportionate influence over consensus or resource allocation. By masquerading as numerous distinct participants, the attacker can manipulate voting processes, censor transactions, or compromise network security. The term “Sybil” traces back to a 1973 novel about a […]
ZK-SNARKs vs ZK-STARKs: Ultimate Comparison Guide
Zero-knowledge proofs let you validate computations without revealing underlying data. ZK-SNARKs and ZK-STARKs both deliver succinct proofs, but they diverge on trust assumptions, transparency, quantum resistance, proof sizes, and computational trade-offs. This post unpacks definitions, core differences, practical use cases, and future directions to help you choose the right technology for your project. So dive […]
The DAO Attack – Reentrancy Vulnerability
The DAO attack on Ethereum in 2016 stands as the most famous reentrancy exploit in smart contract history. By recursively withdrawing funds before its internal state could update, an attacker drained about 3.6 million ETH in a matter of hours. This blog post unpacks how reentrancy works, walks through The DAO vulnerability, and outlines prevention […]
How to do Fundamental Analysis of Cryptocurrencies?
Investing in cryptocurrencies without understanding their underlying value is like sailing in open waters without a compass. Fundamental analysis equips you with the tools to evaluate a project’s long-term viability by examining its technology, team, tokenomics, and on-chain metrics, rather than chasing short-term price swings. Understand Project Fundamentals Start by diving into the project’s core […]

Types of Consensus Mechanisms – Lotus Crypoos
Blockchain networks rely on consensus mechanisms to validate transactions, secure the ledger, and coordinate participant behavior. Each algorithm balances three core properties—security, scalability, and decentralization—in different ways. Choosing the right consensus mechanism directly impacts a network’s performance, cost, and energy footprint. Proof of Work (PoW) Proof of Work is the pioneering consensus protocol that powers […]
