Kaspa v2.1.0 is out [Link in the reply] All node, mining, and infrastructure operators across mainnet and testnets are strongly encouraged to upgrade. This release introduces P2P Protocol Version 11, extracts a standalone ZK SDK, and reflects an ongoing focus on proactive defense-in-depth across the node architecture. Key Highlights: • P2P Protocol Version 11 & Chunked IBD: Large Initial Block Download (IBD) payloads (including Pruning Point Proofs, headers, and trusted data) are now streamed in 20 MiB chunks. This eliminates message- framing bottlenecks and timeouts during node sync, backed by overall safety limits and transfer timeouts, while maintaining full backwards compatibility with Protocol 10 peers. • Standalone ZK SDK: Zero-Knowledge proof and script-generation tooling has been extracted into a dedicated crate (kaspa-txscript-zk-sdk). It adds support for RISC Zero Groth16 and STARK verifier generation with dynamic or static image IDs, bounds control proofs against oversized inputs, and resolves cross-platform build issues. • General Hardening: Comprehensive defense-in-depth upgrades across the node, including stricter P2P message and block limits to guard against DoS vectors, a workspace-wide arithmetic safety audit to eliminate overflow risks, enhanced stratum bridge stability, and tighter consensus validation. These structural safeguards significantly strengthen node resilience and provide higher confidence in overall network security.
