Understanding ZK verification is crucial for blockchain integrity. It’s a complex process that CertiK is pioneering to ensure that every step in a ZK VM Chain’s execution is mathematically verified to be secure and correct. What Is It? ZK instructions are like precise mathematical puzzles. Each one must fit perfectly to maintain a secure ZK Chain. If even one instruction is off, it’s akin to a missing piece that could compromise the entire system. What Does It Mean? When executing a ZK instruction, the focus is on preserving a valid state within the ZK VM. CertiK ensures each operation transitions accurately to a predetermined, secure state, affirming the system’s integrity. What Does It Take? To achieve this, we have to tackle three things: stack memory consistency, arithmetic precision, and execution flow accuracy. Each is a commitment to meticulous scrutiny, ensuring that ZK proofs stand up to the highest assurance level.

Dive into the cutting-edge world of cybersecurity with our exploration of Zero-Trust Architecture—an approach that doesn't just patch up the weaknesses of the past, but revolutionizes how we protect our digital landscape. In this journey, we unveil how Web3, with its blockchain foundations, transforms the internet into a fortress without walls, where each transaction is transparent and trust is not assumed, but cryptographically verified. Say goodbye to the vulnerable systems of old and welcome a new era where every interaction is secure by design, creating an online ecosystem that's as robust as it is revolutionary. Join us to discover how the Zero-Trust model is paving the way for a safer, smarter, and more secure future online.

In 2023, the Web3 security landscape experienced significant changes, as detailed in CertiK's Annual Report. The year saw a notable decrease in financial losses due to hacks, scams, and exploits, down to $1.8 billion, which is 51% less than in 2022 and 65% lower than in 2021. Despite this positive trend, the number of incidents rose to 751, indicating ongoing vulnerabilities. November emerged as the costliest month, with losses totaling $363 million. Private key compromises were identified as a primary cause, responsible for half of the year's losses. The report also explores intriguing cases like KyberSwap and analyzes the correlation between DeFi’s Total Value Locked (TVL) and the losses incurred. CertiK's achievements in 2023 included launching the SkyInsights platform, earning accolades for mobile security, and receiving a significant bug bounty from SUI. This highlights the company’s proactive approach in the evolving field of Web3 security.
