01 / HARDWARE SILICON ISOLATION

Beyond Software Boundaries.
Hardware-Attested Enclave Compartments.

Traditional containerization was engineered for application packaging using Linux cgroups and namespaces, which provide operating system process segmentation rather than cryptographic hardware defense. When workloads share a common host kernel, system-level vulnerabilities can expose memory and execution state.

BlockBox Pods™ enforce isolation directly within CPU silicon registers. Workloads launch inside hardware-encrypted memory compartments where host operators and root administrators cannot inspect or alter state. BlockBox runs natively on Intel TDX and AMD SEV-SNP bare-metal servers or confidential cloud instances.

03 / ARCHITECTURAL EVOLUTION • CVM TO MICRO-POD

Beyond Whole-OS Virtualization.
The Evolution from Heavy CVMs to Native Micro-Enclaves.

First-generation confidential computing established hardware memory encryption through Confidential Virtual Machines (CVMs). While CVMs proved that hardware encryption is viable at scale, encapsulating an entire 4 GB general-purpose Linux operating system inside the enclave introduces multi-minute boot cycles, substantial memory overhead, and millions of lines of unnecessary guest OS code within the trusted execution boundary.

BlockBox Pods™ represent the next evolutionary tier. Rather than running an entire guest operating system, BlockBox provides razor-thin, purpose-built micro-enclave appliances that map application binaries directly onto CPU silicon registers. Designed to run natively across major confidential cloud environments—including Google Cloud, AWS, and Microsoft Azureor sovereign on-premises bare metal, BlockBox achieves sub-50ms cold starts with a minimal 18 MB footprint.

Host Hardware Requirement:
INTEL TDX OR AMD SEV SERVER

To install and run BlockBox in production, your host must be an Intel TDX server (Xeon 4th/5th Gen+) or an AMD SEV server (AMD SEV-SNP on EPYC Milan/Genoa/Bergamo+). Compatible with bare-metal servers or confidential cloud instances (GCP, Azure, AWS). For local macOS/Linux development, use blockbox run --dev for simulated attestation.

07 / THE HARDWARE SECURITY IMPERATIVE

The Physical Layer Imperative.
Why High-Value Workloads Require Silicon Enclaves.

Enterprise banking, proprietary AI models, and mission-critical financial workloads increasingly operate in untrusted or multi-tenant cloud environments. Traditional software abstractions—operating system boundaries, shared host memory, and centralized daemons—leave execution state exposed at the physical hardware layer.

THREAT 01 MEMORY EXPOSURE VECTOR

Cleartext Host DRAM & Bus Inspection

In standard cloud infrastructure, data residing in dynamic RAM is held in cleartext. Hypervisors, host kernel modules, and low-level diagnostic interfaces have physical access to host memory registers, exposing proprietary model weights, private signing keys, and sensitive financial payloads.

BlockBox Architecture: Hardware AES-XTS-256 bus encryption (Intel TDX / AMD SEV-SNP). Data in RAM is encrypted before it leaves the CPU die, ensuring memory bus inspection remains mathematically infeasible.
THREAT 02 RUNTIME OVERHEAD & ATTACK SURFACE

Heavy Runtimes & Dependency Sprawl

Enterprise application stacks frequently deploy massive runtime footprints into production—incurring multi-minute cold starts, garbage collection jitter, and thousands of transitive third-party dependencies that expand the operational attack surface.

BlockBox Architecture: Sub-45ms daemonless micro-enclaves. 18MB compiled native footprint, zero external runtime overhead, deterministic execution, and hermetically sealed binaries.
THREAT 03 HOST PRIVILEGE VECTOR

Host Daemon Privilege Escalation

Standard container engines depend on centralized background daemons running with elevated host privileges. When multiple workloads share a common Linux kernel, unpatched kernel vulnerabilities or container breakout flaws can grant unauthorized access to the host.

BlockBox Architecture: 100% Daemonless. Workloads execute inside dedicated CPU-enforced hardware compartments. Zero root background daemons or shared host sockets exist to compromise.
THREAT 04 HOST HYPERVISOR BOUNDARY

Hypervisor Boundary & Multi-Tenant Exposure

In standard virtualization architectures, the hypervisor operates with ring-0 administrative control over all tenant workloads. Workloads running in shared environments rely entirely on host hypervisor isolation, meaning root access to the physical host permits inspection of running memory and keys without tenant notification.

BlockBox Architecture: Hardware-enforced Intel TDX RTMR and AMD SEV-SNP VMPCK registers cryptographically isolate the workload from the host hypervisor. Memory pages are hardware-encrypted with ephemeral keys managed strictly by the CPU security processor.
