Commit-Reveal

Picoin uses a commit-reveal workflow to reduce the possibility of miners selectively calculating only validation samples.

The mining process is divided into two phases:

Commit Phase

The miner computes the assigned segment and submits:

• result hash;
• Merkle root;
• metadata.

At this stage, the miner does not yet know which samples will later be verified.

Reveal Phase

After the commitment is accepted, the protocol generates deterministic validation samples.

The miner must then reveal:

• requested positions;
• corresponding values;
• Merkle proofs.

This mechanism helps prevent selective computation attacks.
