Protocol architecture

Engineered for scale, privacy, and speed

A specialized Layer 1 optimized for verifiable credentials and zero-knowledge proofs — built on proven cryptographic primitives and open standards.

A Purpose-Built Stack

Unlike general-purpose blockchains, every layer of the Solidus architecture is optimized for secure credential management.

Layer 3

Applications & Wallets

Consumer interfaces, enterprise dApps, and identity wallets built using Solidus SDKs.

Mobile Identity Wallets
Enterprise Admin Dashboards
Credential Issuance APIs
Layer 2

Protocol Logic

The core verification logic, credential schemas, and smart contracts governing identity flows.

Zero-Knowledge Verifiers
DID Registries
Revocation Accumulators
Layer 1

Validator Network

The underlying Proof-of-Stake consensus mechanism ensuring finality and immutability.

BFT Consensus Engine
21-Node Committee
f < n/3 Byzantine Tolerance

Zero-Knowledge Primitives

The vision behind Solidus: prove anything about yourself, without revealing anything else. Ed25519 credentials are live today, BBS+ selective disclosure is live on testnet (audit pending), and ZK predicate proofs remain on the roadmap.

Credential Issuance

Zero-Knowledge Proof

Verification

Credential Issuance Details

A trusted issuer (e.g., DMV, Bank) signs a verifiable credential containing your private data and delivers it to your local wallet.

Today: Ed25519 signatures — the credential is signed with the issuer's private key and bound to the holder's DID. Only the holder possesses the raw credential data. BBS+ selective-disclosure signatures over BLS12-381 (per IRTF draft-irtf-cfrg-bbs-signatures) are live on testnet; external audit pending.

Network Performance

Solidus is engineered to handle enterprise-grade identity volume without compromising decentralization or speed.

Throughput

2K–10KTPS

Current testnet throughput. Target: 50K+ TPS on mainnet.

Block Time

~2.5s

HotStuff BFT with 3-chain finality on testnet.

Transaction Cost

$0.001/tx

Target flat-fee pricing independent of network congestion.

Mainnet Target

50K+TPS

Roadmapped optimizations leveraging parallel execution.

Consensus

BFT

HotStuff-based Byzantine fault tolerance with leader rotation.

Testnet Validators

4Nodes

Multi-validator testnet live. Open validator program coming soon.

Verifiably Open Source

Security requires transparency. The Solidus protocol, cryptography primitives, and smart contracts are entirely open source and available for public audit.

Open infrastructure for verifiable identity.
