How Roru Protects You
How Roru Protects Your Privacy and Security
Roru Labs provides multiple layers of protection that work together to ensure your financial privacy and security. This section explains the specific mechanisms and guarantees that protect you when using Roru.
Privacy Protection Layers
1. Cryptographic Privacy
Zero-Knowledge Proofs
Every Roru transaction generates a zero-knowledge proof that verifies:
Balance Sufficiency: The sender has enough funds (without revealing the amount)
Value Conservation: No value is created or destroyed (without revealing amounts)
Authorization: The sender is authorized to spend (without revealing identity)
Double-Spend Prevention: The note hasn't been spent before (without revealing which note)
These proofs are cryptographically unbreakable under standard cryptographic assumptions. Even with unlimited computational power, an attacker cannot extract information from the proofs.
Shielded State
All balances in Roru are represented as cryptographic commitments in a Merkle tree:
Amount Hiding: Transaction amounts are hidden via Pedersen commitments
Balance Privacy: Your total balance is not visible on-chain
State Verification: You can verify state without revealing information
Efficient Updates: State updates are efficient despite privacy
Unlinkability Guarantees
The Roru Protocol provides formal unlinkability guarantees:
Transaction Unlinkability: Transactions cannot be linked to each other
Address Unlinkability: Addresses cannot be correlated
Temporal Unlinkability: Timing cannot be used to link transactions
Amount Unlinkability: Amounts cannot be used to link transactions
2. Network Privacy
Encrypted Communication
All network communication in Roru is encrypted:
End-to-End Encryption: Data encrypted from device to infrastructure
RPC Encryption: All RPC calls are encrypted
State Sync Encryption: State synchronization is encrypted
Metadata Protection: Network metadata is protected
Relayer Privacy
Roru relayers provide additional privacy:
Transaction Mixing: Transactions are mixed before broadcasting
Batching: Multiple transactions batched together
Timing Obfuscation: Transaction timing is obfuscated
No IP Correlation: IP addresses cannot be linked to transactions
Infrastructure Privacy
Roru Infra processes data in encrypted environments:
TEE Processing: Data processed in Trusted Execution Environments
