Privacy in LLMs: Securing Enterprise Data Without Losing Performance

No confidential AI method is free. Each trades away speed, utility, hardware budget, or security. Compare five approaches for running LLMs on sensitive data: cryptography, TEEs, obfuscation, differential privacy, and hybrid splits.

Writing Zig Native Node.js Addons Without N-API Boilerplate

Writing native Node.js addons in Zig shouldn't mean drowning in N-API boilerplate. Enter zapi: a tool featuring a new high-level DSL that automatically turns plain Zig functions into type-safe JavaScript APIs at compile time, blending low-level control with a seamless developer experience.

The 2026 Guide to Blockchain Privacy: 5 approaches for institutional adoption

Blockchain privacy has moved from ideology to architecture. Explore privacy approaches, from ZK-Rollups and private L2s to TEEs and FHE, shaping institutional digital asset management in 2026.

Investigating a Zcash Web Wallet

ChainSafe R&D has been investigating the feasibility of a Zcash web wallet. Such a wallet would allow easy onboarding to Zcash. It is also the first step in building a browser extension wallet or a MetaMask snap.

Forks Aren't Always Safe

Forks Aren't Always Safe

Forking open-source smart contracts is risky. Developers often inherit existing bugs or create new ones through modifications, leading to major exploits like those seen with Grim Finance and Meter. Transparency, collaboration, and auditing new logic are crucial to prevent costly vulnerabilities.

Improving Web3 UX: Deferred Transaction Inclusion

Waiting for transaction inclusion doesn't have to mean, halt and wait. Let's set the stage a bit... I'm a liquidity provider (LP) for a DeFi protocol and receive LP tokens. I can stake those LP tokens and receive bonus rewards ("farming"), which

Onchain Dispute Games: Past, Present and Future

Research & Development

Onchain Dispute Games: Past, Present and Future

Blockchains use dispute games to efficiently verify computations. Instead of costly on-chain execution, a statement is accepted unless challenged. Protocols like one-step fraud proofs and bisection games resolve disputes, saving resources by only performing full verification when necessary.

Transaction fee mechanism design

Transaction fee mechanism design

For a sustainable decentralized ecosystem, it is essential to align incentives. This prevents the system from favouring one actor too much.
