Technical Deep-Dive
Understand the technical differences between Aztec's zero-knowledge proofs and Radix's atomic composability.
Aztec Network uses advanced cryptographic techniques called zero-knowledge proofs (ZKPs) to enable privacy on public blockchains.
Key Components:
- • PXE (Private Execution Environment): Runs on student's device, generates proofs without revealing data
- • Rollup Provider: Batches transactions for privacy
- • Noir Circuits: Domain-specific language for ZK proofs
- • Confidentiality Layer: Additional encryption for sensitive data
Benefits:
- ✓ True privacy - network only sees proofs, not data
- ✓ Verifiable - proofs can be verified mathematically
- ✓ Selective disclosure - reveal only what's needed
- • Ethereum L2 ecosystem access
Radix Engine is a novel consensus mechanism that guarantees atomic execution of multiple operations in a single transaction.
Key Components:
- • Cerberus Sharding: Network scales linearly by adding shards
- • Scrypto: Resource-oriented programming language
- • Transaction Manifests: Simple, powerful way to bundle operations
- • Native Resources: Built-in asset system without smart contracts
Benefits:
- ✓ All-or-nothing - no partial execution failures
- ✓ Simple multi-contract interactions
- ✓ Predictable execution - fixed fees
- ✓ Developer productivity - easier to learn
- • Linear scalability - add shards, get linear performance
