This post compares the concept of Token Toxicity, where stakers don't attack a protocol in fear of depreciating their staked tokens, to Slashing security. Slashing offers stronger security as it individually penalizes malicious actors, resulting in a higher cost of corruption. Protocols stand to gain more from adopting Slashing than relying solely on Token Toxicity.

Solana's program security is critical to ensuring applications behave as intended, affecting performance, scalability, and interoperability. As such, developers must understand potential attack vectors and vulnerabilities such as logic bugs, data validation flaws, and access control vulnerabilities and employ strategies like rigorous testing and code auditing to mitigate risks. This comprehensive guide delves into common vulnerabilities developers might face, offering insights and mitigation strategies to safeguard Solana programs against exploits.

Vitalik Buterin is urging the Ethereum network to implement automated responses to potential 51% attacks to reduce the reliance on social consensus and improve the network's resilience. He also highlighted the importance of adopting light clients, ensuring quantum resistance, and simplifying protocols for enhanced security and usability.

Optimism rolled back its fraud proof system to a permissioned fallback mechanism after community-driven audits found multiple vulnerabilities. Two months ago, it reached Stage 1 rollup decentralization when anyone could contest L2 transactions on the mainnet. A proposed network upgrade, including a hard fork named "Granite," is set for September 10, aiming to enhance security without compromising user assets.
