Introducing Substrate: An Open Format for Validator Threat Intelligence
·Simon·7 min read
Validator threat intelligence has no shared format. We're publishing a bundle spec, a ten-family taxonomy, and seeding a 1,092-bundle corpus to fix that.
We Scanned 5,700 [Solana, Eth, Sui, Atom] Validators. Here's What We Found.

NullRabbit scanned 5,715 validator hosts across Solana and Sui, running 10,139 scans and identifying 1,340 CVE findings across 155 hosts. Here's what the validator attack surface actually looks like.
XDP Inline Defense for Validators: Kernel-Level Protection at Line Rate
·NullRabbit Labs·7 min read
Validator nodes face constant exposure. This deep dive explains how NullRabbit Guard uses eBPF and XDP to enforce security directly inside the NIC driver, dropping scans and abnormal traffic at line rate before they reach the kernel or your node.
Validator Slashing Incidents Are a Warning. Sui Could Be Next.
