High performance compressor optimized for binary data

Blosc is a high performance compressor optimized for binary data (i.e. floating-point numbers, integers, and booleans, although it can handle string data too). It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc main goal is not just to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations. C-Blosc2 is the new major version of C-Blosc, and is backward compatible with both the C-Blosc1 API and its in-memory format. However, the reverse thing is generally not true for the format; buffers generated with C-Blosc2 are not format-compatible with C-Blosc1.

Checksums e datas de observação

For an APT source, signature verification authenticates the repository metadata chain and the Packages index containing this source-reported artifact digest. It does not certify package safety.

2.21.2-1.fc43 / aarch64Observed Sep 1, 2026 to Sep 1, 2026

Verification status: Metadata observed; artifact bytes were not independently fetched or hashed by this catalog import. The digest below is source-reported.

After downloading that exact artifact, compare its bytes with the source-reported expected digest:

printf '%s %s\n' '371a6540252b2b38354198537f54d1b81f741a2c654e4f3d5c92184b9c46e8dc' 'blosc2-2.21.2-1.fc43.aarch64.rpm' | sha256sum --check --strict -

A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.
