Introducing Secstant by Sigma Prime. Pointing LLMs at your code isn't enough to secure it. The cost adds up, the review has no direction and false positives pile up. We built Secstant to fix that. It's already found bugs in repos from NASA and IPFS, all fixed upstream. Here's how 👇

It was a big few days at DSS for the Sigma Prime team. Proud to once again support this event as a sponsor and see our team contributing on stage. Shoutout to @ethzed, @kirkthebaird, @TheKnapsy, and @ToonVH_ Great sessions. If you missed them or want to rewatch, recordings below 🍿

Despite having our hands full at @EFDevcon, we couldn’t resist sharing @jimmygchen's new blog exploring a Lighthouse–Reth integration 😮

Sigma Prime turned nine last week 🎂 A remarkable journey so far and we’re just getting started. Huge thanks to everyone who makes SigP what it is, and to all our incredible clients and community!

How does Quantum Key Distribution actually secure data? Let's break down the physics behind "unhackable" encryption 🧵

Think implementing nonces is simple? Think again. Whether you're building onchain protocols or offchain infrastructure, proper nonce implementation is one of the trickiest parts of cryptographic security. Let's dive into why replay protection is harder than it looks 👇

We've released Lighthouse v8.0.0-rc.0! The next Ethereum upgrade Fusaka is coming to testnets! 🎉 This upgrade is a major step forward for scaling L2s with more blobs 🦓 If you’re running a holesky / hoodi / sepolia testnet node, you must upgrade before the fork.

We just wrapped up a security review of @berachain's dual execution client implementation using Reth SDK + Go-Ethereum for their BRIP-0004 enshrined rewards system. 🛡️ Client diversity wins: ➡️ Differential fuzzing between bera-reth & bera-geth caught consensus bugs that would've caused non-determinism in CometBFT ➡️ Cross-client validation revealed edge cases hard to detect in single-client development ➡️ Alternate language approaches exposed implementation gaps before mainnet 💡@paradigm Reth SDK shines here: ✅ Built fully custom execution layer with enshrined system calls ✅ No need to fork/maintain an entire codebase - pure modularity ✅Granular component customisation (consensus, EVM, RPC, tx pool) ✅ Production-ready (powers Base, Gnosis, BSC implementations) This is client diversity doing its job - catching bugs that matter. 🚀

🔬 Thread: Why the @boundlesshq zkVM approach to Ethereum consensus verification matters (and the security challenges we found) Traditional cross-chain bridges require trust assumptions. "The Signal: Ethereum" by Boundless eliminates this through cryptographic proofs, but the devil's in the details...

Ever stared at 500k+ lines of blockchain node code wondering where to even start? We've been there. Reviewing core node implementations can be particularly challenging due to their complexity and scale.

Lighthouse v7.1.0 Fantabulous is out! This is an exciting release packed with major improvements: 📉 Hierarchical state diffs are now in the hot DB - reducing disk I/O by 4x during normal ops and using 10x less space during non-finality. ⛽ Default gas limit bumped to 45M - following extensive analysis by core devs to safely raise L1 throughput. 🔦 Light client updates are now gossiped by sync committee validator nodes, boosting light client data availability.
