Ever since the existence of Bitcoin, a digital innovation world has been enabled, and digital currencies and technological solutions have appeared based on decentralized and peer-to-peer principles. Bitcoin was envisioned for use in payments, but as it grew, issues about scalability also increased to a large extent. Scalability issues in the Bitcoin network today include
Blockchains have emerged as independent ecosystems of global financial activity. Ensuring the blockchains’ availability, validity, and security are the consensus mechanisms that extend to the transactional foundations within the blocks of the blockchain. For PoS, which has become the most popular consensus mechanism, the amount of staked capital is the determining factor that proportionally increases
Learn how DePIN democratizes infrastructure management using blockchain technology and crypto rewards. Explore its potential and challenges.
Bitcoin network is secure, decentralized, but not scalable. Explore how Layer 2 solutions (Lightning, Stacks, Liquid, Rootstock) unlock Bitcoin-native trading and dApps.
WebAssembly has emerged as a portable and performance-oriented virtual machine, making it an appealing target for Web3 developers.
As a blockchain auditor with the lowest post-audit exploit rate on the market, we at Hacken want to offer our expert review of smart contract auditing tools to help Web3 developers deploy more secure code.
While most hacks in Web3 come as rug pulls and access control compromises, smart contract vulnerability exploits account for a regularly significant share of losses. In Q3 2023, Web3 projects lost nearly $100M due to smart contract hacks. With so much money at stake, it’s at least understandable why smart contract developers go over the
Upgradeable smart contracts are bringing flexibility to the otherwise immutable code. Many companies, such as Compound Finance and OpenSea widely adopt them as the future of smart contract development. However, security problems are also emerging. Critics say upgradeability weakens blockchain’s immutability, while supporters believe it enhances safety by addressing bugs and preventing exploits. Let’s break
A blockchain oracle supplies external data to smart contracts, enabling them to fetch data from other chains and the outside world. Are oracles secure? Let’s find out.
