Poseidon-BN254 Enclave Acceleration & Groth16 Pipeline
Released: 2026-07-15
- Hardware-accelerated Poseidon BN254 hash sponge — 38% latency reduction in Stage 5 ZKPG
- Groth16 proof pipeline refactored for parallel batch verification across enclave nodes
- Stage 3 HSM enclave runtime upgraded to support multi-tenant payload isolation
Major kernel release introducing hardware-accelerated Poseidon BN254 hash sponge operations, optimized Groth16 proof generation pipeline, and Stage 3 enclave runtime improvements reducing average verification latency by 38%.
Hardware-accelerated Poseidon BN254 hash sponge operations integrated into Stage 5 ZKPG verifier, reducing average proof generation time from 22ms to 14ms.
Stage 3 HSM enclave runtime upgraded to support multi-tenant payload isolation with dedicated memory sandboxing per `.dhc` container session.
New Developer SDK v4.2.0-LTS released with Rust and Go runtime bindings, native async proof submission, and CLI toolchain for local circuit testing.
Groth16 proof pipeline refactored for parallel batch verification. Throughput increased from 450 proofs/sec to 1,200 proofs/sec on standard enclave nodes.
Patched timing side-channel vulnerability in Ed25519 signature verification path within the PIL identity gate. CVE-2026-4821 resolved.
`.dhc` container spec v2.1.0 introduces mandatory BN254 hash root enforcement. Legacy v1.x containers must be re-signed using the migration CLI tool.
Run `disha-cli dhc migrate --from v1.x --to v2.1.0` on all existing container artifacts before upgrading enclave nodes to v4.2.0.
Fixed race condition in Stage 2 CEL evidence block generation that could cause duplicate EvidenceBlock entries under high-concurrency write loads (>500 concurrent sessions).
