Cryptographic proof that specific code is running inside a hardware-isolated enclave. ZeroCopy uses AWS Nitro Attestation to prove the exact binary running in production.
Autonomous Trading
Trading
Algorithmic trading systems that execute trades without human intervention. Requires deterministic signing infrastructure to prevent agent errors from becoming legal liability.
Circuit Breaker
Risk
Hardware-enforced risk limit that physically prevents transactions exceeding pre-defined thresholds. Unlike software controls, cannot be bypassed by operators or attackers.
Enclave
Security
Hardware-isolated execution environment (AWS Nitro Enclave) where private keys exist. No root access, no SSH, no debugging interfaces. Memory is encrypted and inaccessible to the host.
Jitter Tax
Performance
Hidden cost of latency variance in high-frequency trading. Even with low average latency, unpredictable spikes cause missed opportunities and slippage. ZeroCopy eliminates jitter with deterministic 42µs signing.
MEV (Maximal Extractable Value)
DeFi
Profit extracted by reordering, inserting, or censoring transactions in a blockchain block. ZeroCopy's low-latency signing enables MEV-aware execution strategies.
MPC (Multi-Party Computation)
Cryptography
Cryptographic technique where multiple parties jointly compute a signature without any single party holding the full private key. Slower than hardware isolation (75ms to 8s+ depending on provider, vs 42µs modeled for ZeroCopy).
PCR0 (Platform Configuration Register 0)
Security
Hash of the enclave image. Used to verify that the exact expected code is running. ZeroCopy publishes PCR0 measurements for independent verification.
Policy Engine
Risk
Pre-execution risk controls enforced in hardware. Validates transactions against limits (volume, counterparty, time-of-day) before signing. Prevents fat-finger errors and unauthorized trades.
Sentinel Core
Product
ZeroCopy's core signing infrastructure. AWS Nitro Enclave with 42µs latency, hardware isolation, and cryptographic attestation.
Self-hosted infrastructure where you control the deployment, keys, and policies. ZeroCopy runs in your AWS VPC, not a shared multi-tenant cloud.
Vsock
Performance
Virtual socket protocol for communication between AWS Nitro Enclaves and parent EC2 instances. Sub-microsecond transport overhead, bypassing the network stack entirely.
Zero-Knowledge Architecture
Security
System design where operators cannot access sensitive data (private keys) even with full system access. ZeroCopy employees cannot extract keys, even under subpoena.
