Projects across the web3 ecosystem increasingly rely on On-Chain credentials of wallets such as Proof of Humanity (POH), wallet scores, and crypto assets that represent badges. The aim is to ensure genuine participation and fair distribution of incentives. This mechanism plays a crucial role in campaigns, allowing for the verification of unique human identities against bots and Sybil attacks. As the Web3 space expands, so does the need for robust solutions to authenticate users. This article highlights the use cases and advantages of this concept, functionality, and leading projects in the on-chain POH and wallet-scoring domain. https://lnkd.in/eik57wVc

Decentralized identity is reshaping the internet, giving users control over their digital identities. Together with Web3's vision, it's paving the way for a new era where users, rather than tech giants, have control over their data. Here's how: 1️⃣ User Empowerment: Users manage their digital identities independently, thanks to blockchain and cryptography. 2️⃣ Interoperability: Seamless identity verification across platforms, enhancing user experience and security. 3️⃣ Enhanced Security: Advanced cryptographic keys and decentralized data storage reduce risks of breaches and identity theft. 4️⃣ Smart Contracts: Automate and secure identity-related transactions, fostering trustless interactions. 5️⃣ dApps Support: Decentralized identities enable secure user authentication, crucial for dApps' growth in Web3. Together, decentralized identity and Web3 are paving the way for a more secure, private, and user-centric internet. 🚀

🚨 Velocore's $6.8 Million Exploit: Fast and Furious Losses in the Crypto Space 🚨 On June 2nd, the L2 DEX Velocore experienced a devastating exploit that resulted in over $6.8 million in losses. This breach affected its liquidity pools on Linea and zkSync, highlighting significant vulnerabilities within its Balancer-style CPMM contract. The Vulnerability and Exploit Velocore's smart contract flaw allowed an attacker to manipulate fee calculations and drain liquidity. The attacker executed a flash loan, simulated massive withdrawals, and manipulated the feeMultiplier to withdraw a large amount of tokens. A final single-token withdrawal minted an excessive amount of liquidity tokens due to an underflow error, enabling the attacker to repay the loan and escape with $6.8 million in ETH. Centralization Concerns In an effort to mitigate further losses, the Linea team halted block production, which raised centralization concerns. While Linea has since resumed operations, their decision underscores the delicate balance between security and decentralization in blockchain protocols. Audit and Security Failures Despite multiple audits by Zokyo, Hacken, and Scalebit, Velocore's protocol still contained exploitable flaws. Velocore has offered a 10% bug bounty to the hacker, but there has been no response. The attacker obscured their tracks by using Tornado Cash. Attack Details Attacker Address: 0x8cdc37ed79c5ef116b9dc2a53cb86acaca3716bf Exploited Contracts: 0xed4e130f6f9e68918996f7e1e46a3306b3e12cec 0xb7f6354b2cfd3018b3261fbc63248a56a24ae91a 0xc030fba4b741b770f03e715c3a27d02c41fc9dae 0xf7f76b30a301524fe76508546B1e3762eF2B9267 Attack Transactions: 1: 0xed11d5b013bf3296b1507da38b7bcb97845dd037d33d3d1b0c5e763889cdbed1 2: 0x37434e674efc4e7cfeed7746095301ace5636028906fe548b786ead286e35eb0 3: 0x4156d73cadc18419220f5bcf10deb4d97a3d3f7533d63ba90daeabc5fd11ba17 Final Fund Destination (Before Tornado Cash): 0xe4062fcade7ac0ed47ad794028967a2314ee02b3 Velocore's breach highlights the urgent need for robust security and thorough audits in the crypto industry. Despite boasting multiple audits, the presence of critical vulnerabilities suggests a need for improved security practices. As Velocore negotiates with the attacker, offering a bug bounty for the return of funds, the crypto community watches closely. Will this incident be an isolated crash or the first of many? Only time will tell if Velocore can recover and restore confidence in their platform. #crypto #blockchain #security #DeFi #Velocore #cryptoexploit #cybersecurity #blockchaintechnology #cryptonews #decentralization #smartcontract #audit #penetrationtesting #malwareanalysis #liquidity #wallet #protocol #bugbounty
