Vectorized Cryptography

Vectorized BLAKE3

Panama API

BLAKE3 is the fastest cryptographic hash—and we made it faster with Java's Panama Vector API. SIMD instructions process multiple hash lanes in parallel, achieving near-native performance with zero JNI overhead.

✓ 4× throughput vs scalar implementation
✓ Used in Proof of History (PoH) chain
✓ Pure Java—no native libraries
✓ Falls back gracefully on unsupported hardware

// Vectorized BLAKE3 with Panama
var species = IntVector.SPECIES_256;
var v0 = IntVector.fromArray(species, state, 0);
var v1 = IntVector.fromArray(species, state, 8);

// G function vectorized across lanes
v0 = v0.add(v1).add(m0);
v3 = v3.lanewise(XOR, v0)
       .lanewise(ROR, 16);

// 4 lanes processed simultaneously
v0.intoArray(state, 0);

Vectorized Dilithium-3

Post-Quantum

Dilithium-3 (ML-DSA) is our post-quantum signature scheme. The Number Theoretic Transform (NTT) at its core is naturally parallelizable—we exploit this with Panama to accelerate polynomial operations.

✓ 2× faster NTT operations
✓ NIST FIPS 204 compliant
✓ Bouncy Castle integration
✓ Resistant to Shor's algorithm

// Vectorized NTT butterfly
var species = IntVector.SPECIES_512;

for (int j = 0; j < len; j += species.length()) {
    var a = IntVector.fromArray(species, poly, j);
    var b = IntVector.fromArray(species, poly, j + half);
    
    // Montgomery reduction vectorized
    var t = b.mul(zeta).lanewise(AND, MASK);
    
    b.sub(a).intoArray(poly, j + half);
    a.add(t).intoArray(poly, j);
}

Apeiron Storage Engine

💾

Tiered Storage Architecture

NEW

Dynamis introduces Apeiron—a tiered storage engine that automatically balances RAM usage with disk persistence. Validators choose their optimal mode based on hardware constraints.

✓ HYBRID (Default): Hot Tier in RAM + Cold on Disk. Best for Validators.
✓ MEMORY: All-RAM. Extreme performance for benchmarks.
✓ DISK: Minimal RAM. Best for Archive Nodes.
✓ Backpressure Safety: Dirty block tracking prevents data loss.

// Tiered Storage Factory Pattern
if ("HYBRID".equals(storageMode)) {
    storage = new HybridChainStorage(ledgerRepo);
} else if ("DISK".equals(storageMode)) {
    storage = new DiskChainStorage(ledgerRepo);
} else {
    storage = new MemoryChainStorage();
}

// Backpressure: No eviction until persisted
void onBlockPersisted(Block b) {
    dirtyBlocks.remove(b.getIndex());
}
