tau

Structure-aware storage for Ethereum-class transaction data — compact, individually addressable, readable while still compressed.

Tau stores blockchain structure, not just bytes. On the public demo corpus (5,670 Ethereum RPC JSON transactions, 12.41 MB): 5.53× lossless (2.24 MB compressed), with sub-2µs query-in-place and 5,670/5,670 byte-exact round-trip verified across platforms. It exploits structure within RPC-JSON workloads; on unstructured noise it falls back to ≈1× and never inflates output. Byte-exact recoverable, independently verifiable, queryable while still compressed — without exposing the engine. The core is sealed. The evidence is not.

one engine · target markets

one engine. multiple target markets.

Tau is a structure-aware storage engine for blockchain data. It makes a narrow, testable claim: blockchain transaction data contains stable structure, and storage engines should use that structure directly. The same engine serves indexers/analytics/data-warehouses (such as Dune, Allium, The Graph) and archive-node/RPC/L1-L2 infrastructure. Both target signed transaction history (canonical RLP format) and RPC representations (RPC JSON) using the same sealed structure-aware engine.

Parquet must store the field. Tau stores the rule that reconstructs it.

Blobs changed the tariff layer. Tau attacks the payload layer.

inclusion is not representation · availability is not compression · hashing is not payload economics
superior density · structure-aware storage

superior density — using a sealed structure-aware codec.

On real RPC JSON transaction data Tau reaches 5.53× lossless density on the verified 5,670-tx corpus — with O(1) query-in-place in sub-2µs. Tau beats general-purpose codecs on the same corpus; exact comparator figures are shared under NDA and regenerate on your corpus during BYOC evaluation.

Per-tx archivers trade density for access. Tau keeps both — read a field while the archive stays packed.

for the skeptic · verify it yourself

“just delta-compression,” says the skeptic. the code says otherwise.

General-purpose compressors win by hunting repeated bytes. Tau works a layer up — on the structure of the transactions themselves. Same density, reached a different way. Don’t take the claim on trust — run the benchmark on your own corpus and read the table it prints.

evidence brief

a verification challenge, not a compression claim.

Every figure below was produced by running the engine on 2026-06-24 (Mac arm64), not quoted from a doc. Run logs are retained. Tau does not ask the market to believe — it asks the market to reproduce.

what tau is
  • A sealed transaction-representation engine.
  • A bit-perfect recovery path.
  • Buyer-side integrity verification.
  • A buyer-side verification model.
  • Infrastructure-oriented throughput.
what tau is not
  • Not a blob replacement.
  • Not a Merkle replacement.
  • Not a generic compressor.
  • Not a public-source release.
  • Not a universal cost-reduction claim.
  • Not externally crypto-audited yet — the construction is novel; independent audit is scheduled and available to evaluation partners under NDA.

If Tau fails, your corpus proves it. If it holds, your pipeline has a representation problem worth quantifying.

The same corpus replayed on 6 machines across 4 CPU families (AMD Ryzen 9, AMD Ryzen 7, AMD EPYC, Apple M2, and Intel). The compression ratio is identical (5.53× lossless) everywhere, and round-trip verification passes on all hosts.
