We are releasing prior art documentation for a proprietary, real-world file compressor built by Empire Technologies LLC.

This system is not theoretical, benchmark-tuned, or optimized for small files. It was engineered for extremely large, high-entropy real-world data, and delivers major compression gains that are measurable, repeatable, and already in operation.

Claim

This is a prior public disclosure of capabilities and performance, to prevent future IP conflicts and establish existence. The compressor:

Is a custom file-agnostic universal compressor

Uses no GPU or hardware acceleration (CPU only)

Targets gigabyte → terabyte raw files (not synthetic toy datasets)

Achieves consistently measurable compression ratios on hard targets

Outputs fully decompressible results with full bit-matching (SHA-256)

Is real and independently testable

Verified Cryptographic Exhibits (select, timestamped)

ECC = Empire Compressed Container (public, neutral label replacing internal extension names). Each exhibit below corresponds to a file pair recorded in Empire timestamp manifests / Proof Pack (anchor: 2025-09-18) and is verifiable by SHA-256 and the recorded timestamps.

Consumer Rig Throughput Exhibit

Single NVMe lane sustained ~2.1 GB/s. Dual NVMe lanes sustained ~3.8 GB/s on a 95 GB continuous payload, with recorded peak spikes near 24 GB/s in isolated runs. I/O starvation, not compute limits, was observed. These consumer-rig runs produced the same ultra-collapse behavior on 2 GB-class inputs (254×–339×; 99.60%–99.71% reduction). See Proof Pack speed manifests for telemetry.

Minimal Verification Steps

Compute SHA-256 of original and ECC outputs

Windows PowerShell: Get-FileHash -Algorithm SHA256 C:\path\to\file

Linux/macOS: sha256sum /path/to/file

Compare with hashes listed above.

Decompress using Empire decompressor in sandbox: empire_decompress -i ECC_file -o recovered_file Then verify: sha256sum recovered_file (must equal SHA-256(original))

Timestamp linkage: Proof Pack JSON manifests contain matching SHA-256 values with timestamp marker 2025-09-18. Public posting date establishes external publication timestamp.

This is a single publication event. No further clarification will be issued.
