    Real-world asset (RWA) tokenization reached $35.68 billion in 2025, with projections to hit $2 trillion by 2028. But the rapid growth exposed critical vulnerabilities: $14.6 million was lost to hacks—more than double the previous year—with most exploits occurring in DeFi wrappers rather than the tokenized assets themselves.
    The GENIUS Act provided regulatory clarity for stablecoins but left gaps across the full asset lifecycle. Meanwhile, institutional giants like BlackRock, JPMorgan, and State Street are building on private blockchains, validating the market but creating interoperability challenges.
    Platforms like Mavryk (tokenizing $10B in luxury real estate), Ondo Finance (Treasury-backed tokens), and Securitize (infrastructure provider) are attempting to bridge institutional compliance with public blockchain efficiency.

    Deepfake technology has its greatest impact on people through identity theft. It is no longer just fake videos on social media; even a few seconds of voice recording can create a convincing scam. The real challenge for consumers is not so much the deepfake itself, but the fatigue of trying to verify it.

    Large Language Models face growing security threats from adversarial attacks including prompt injection, jailbreaks, and data poisoning. Studies show 77% of businesses experienced AI breaches, with OWASP naming prompt injection the #1 LLM threat. Attackers manipulate models to leak sensitive data, bypass safety controls, or degrade performance. Defense requires a multi-layered approach: adversarial training, input filtering, output monitoring, and system-level guards. Organizations must treat LLMs as untrusted code and implement continuous testing to minimize risks.
