By Dyma Budorin, CEO of Hacken I have a dream: transparent, secure and fair CEX. Centralized cryptocurrency exchanges (CEXs) have seen huge progress in capabilities and safety measures since the early days of digital asset trading. However, uncertainty persists around core issues, including asset custody, assets listing, trading transparency, and security. CEXs that consider trading
OP Stack chains today secure roughly $5 billion in user assets by publishing an output root to Ethereum every few minutes. Fault proofs make the output root falsifiable. But a proof only works if the verifying VM can replay the exact same inputs the rollup saw. Delivering those bytes – securely and deterministically – takes
Multi-platform Penetration TestingMarch–April 2025 Overview MEXC is one of the world’s top cryptocurrency exchanges, serving over 40 million users globally. Known for its high-speed transaction engine and a massive selection of trading pairs (3,000+), MEXC is a go-to platform for both retail and institutional traders. As MEXC scaled its operations and mobile footprint, it engaged
While zero‑knowledge integrations such as OP Succinct inch closer to production, most of the value locked in Layer‑2 still depends on “optimistic” assumptions – thanks to simpler design, stronger tooling, and years of battle‑testing. That puts Optimism’s Fault Proof System on center stage as the last line of defense for billions in L2 value. Fault Proofs 101
Decentralized Finance (DeFi) protocols have revolutionized financial services, offering permissionless lending, borrowing, and trading. And despite market fluctuations, DeFi protocols held over $100 billion in Total Value Locked (TVL) as of May 2025. This concentration of value makes robust security paramount. Pioneering lending protocols like Compound (founded in 2017, with major versions V2 in 2019
Uniswap V2 (main-net launch 18 May 2020) is still responsible for ~40 % of Uniswap TVL on Ethereum mainnet and many L2 roll-ups despite V3/V4 advances. Integrators therefore inherit its design trade-offs and latent attack surface. Many articles describe the main ideas of the protocol, and the contracts are considered secure due to their long
The DualDefense Flash Pools MVP successfully demonstrated the viability of real-yield security staking, proving that decentralized audit pools can create a more secure Web3 environment. However, one major challenge emerged: the limited number of pools available under the initial framework. To make a real impact, we need a broader, more scalable solution. With this goal,
Enterprise adoption of blockchain presents significant opportunities but introduces complex cybersecurity challenges that demand C-suite attention. While the technology promises decentralization and efficiency, the transition from Web2 requires navigating immature security practices and novel threat vectors. Failure to address these risks proactively leads not just to financial loss, but to severe reputational damage, regulatory penalties,
DeFi lending protocols rely heavily on accurate price oracles for determining collateral values, borrowing limits, and triggering liquidations. Traditional Time-Weighted Average Price (TWAP) oracles, while widely adopted, are inherently susceptible to price manipulation, resulting in potentially devastating unfair liquidations and systemic market inefficiencies. The introduction of Uniswap V4’s Truncated Oracle aims to address these critical
