Revolutionary Technology
Discover the cutting-edge consensus mechanism, unparalleled performance, and future-proof security that powers Silica Protocol.
Consensus Architecture
Release design — the target architecture for release, not a snapshot of current implementation. Silica uses a named layered architecture: Tephra ingress batches and disseminates payloads, Tephra orders them through gossip-about-gossip consensus, Crystallite applies the ordered result, Lithification packages proofs and checkpoints, and Cali judges the result — monitoring every layer and enforcing punishment.
Architecture Note
This page reflects the release design source of truth. The names on this page are intentional release layer names. Implementation details and performance metrics evolve as we optimize the network. For technical implementation details, see the GitHub repository.
Canonical shorthand: Tephra ingress = data plane, Tephra = ordering/consensus, Crystallite = execution/apply, Lithification = proofs/checkpoints, Cali = monitoring/enforcement (the judge).
Tephra ingress
Batching and dissemination front end for transaction intake into Tephra consensus.
- • Batches proposal payloads for efficient network fanout
- • Disseminates payloads and references into the ordering layer
- • Keeps batching and network dissemination distinct from consensus ordering
- • Batching and dissemination influence belongs here, not on ordering
Tephra
Gossip-about-gossip consensus layer that turns the shared event DAG into deterministic proposal order.
- • Virtual voting is computed locally from gossip history
- • Same event DAG yields the same order on all honest nodes
- • No extra ordering authority exists beyond Tephra order
- • Ordering truth for the entire protocol
Crystallite
Parallel execution framework that applies Tephra order across deterministic state lanes.
- • Schedules ordered transactions for parallelism
- • Each execution lane is a single deterministic execution context
- • Determinism preserved across replicas
- • Maximizes throughput without re-ordering
Lithification
Once ordered proposals are applied locally, state transitions are final; anchors and proofs package the result for audit, replay, and fast sync.
- • Finality achieved at commit + local apply (no reorgs)
- • Emits anchors, certificates, and checkpoints as proofs
- • Checkpoints simplify audit, sync, and recovery
- • Evidence feeds Cali judgement and enforcement
Cali — the Judge
Cali sees every layer: committee votes, execution evidence, and finalized proofs. It monitors health, judges misbehaviour, and enforces punishment — including slashing.
- • Monitors every layer: votes, execution, proofs, liveness
- • Judges equivocation, invalid proposals, and liveness attacks
- • Enforces slashing and jailing via staking and bank
- • Triggers recovery and restarts on stalls
Layer Stack
Lineation & Lineament
Silica produces periodic anchor blocks that commit the network’s full activity into compact, verifiable checkpoints. Anchors don’t change ordering or finality; they make the chain auditable, recoverable, and easy to synchronize at scale.
- •Per-lane execution/state roots (from execution + monitoring)
- •Shard/global aggregation roots (Merkle roots over receipts & state)
- •GPoD outputs (digests of performance, integrity, and anomaly evidence)
- •PoUW receipts (work proofs summarized into a compact root)

Transaction Throughput (TPS)
Finality Time
Post-Quantum Security
Silica is built with quantum-resistant cryptography from day one, ensuring your assets remain secure even as quantum computing advances.
NIST-Approved Algorithms
Release design: ML-DSA-44/65/87 (FIPS 204) for native accounts, validator authentication, and finality. Chain-wide PQ gaps (transport, randomness, DKS) are tracked in the PQ gap register and DP024 — see the roadmap.
Hybrid Approach
Classical and post-quantum crypto for smooth transition
Future-Proof Design
Upgradeable cryptography without hard forks
Quantum-Resistant Now
While others rush to upgrade, Silica users are already protected against future quantum attacks with proven, standardized cryptographic algorithms.
