Prove the bytes are there.

Prova is a research project exploring verifiable, retrievable storage backed by cryptographic proofs of data possession.

Thesis

Storage should be
verifiable by default.

Centralized storage requires trust. Decentralized storage without proofs requires hope. Neither is enough for the data that actually matters: archives, research, AI corpora, long-lived records. Prova explores a third option, where possession is continuously provable.

Provable possession

Providers respond to random challenges with short Merkle inclusion proofs. Cryptographic, lightweight, and continuous over the lifetime of the stored data.

Content-addressed

Every object is identified by its own binary Merkle commitment. Content and identity are one and the same, computable by anyone from the bytes.

Neutral primitives

No privileged data, no preferred content types, no gatekeepers. One byte is one byte, and one proof means one thing.

Defense in depth

Math first. Hardware attestation and replication are optimizations, never the only line of defense. If the primitive fails gracefully, the system fails gracefully.

Approach

Quiet work,
careful primitives.

We are building in private while we refine the design. No fundraise is active. No token is offered. When the work is ready to share, it will be shared openly.

Open source, open primitives

The cryptographic components are derived from the permissive storage-proofs work published over the past decade by several research communities. We stand on that work, credit it, and contribute back where we can.

No fundraise, no token sale

There is no active ICO, pre-sale, whitelist, or SAFT. If you were directed here expecting one, you were misinformed. Ignore anyone claiming to represent Prova in a fundraising capacity.

Small, deliberate team

Two people, working on this between other commitments. Updates come when the work warrants them, not on a schedule.

Status

Where we are.

This section updates when something is worth updating, not on a schedule.

Earlier research

Design exploration

Several rounds of architecture sketches, threat-model work, and primitive selection. Most of it discarded, which is how it's supposed to go.

Current

Narrowing scope

Consolidating around the smallest useful design: verifiable, retrievable storage on commodity infrastructure, priced and settled in existing money. Fewer moving parts. More confidence in each one.

Next

Reference implementation

When it's ready to look at, it will be available to look at. Not before.

Research, not a product.
Not yet.

Check back when the work is ready. There is nothing to buy, hold, or sign up for in the meantime.
