Offshift Dev Update, Mid-September 2021: Range Proofs 2.0

Offshift is working with Zokyo to develop the platform that will finally bring private finance, or PriFi, live on Ethereum’s Layer 1.

Here’s a progress report since our last update in early September 2021.

Zokyo continues to work on the cryptography for Offshift’s derivatives platform. Recently, the team has been focused on range proofs, and continues to make progress on that front.

What are range proofs?

Range proofs are fundamental to the value proposition of zero knowledge cryptography — specifically, the ability to verify information without revealing it. Range proofs are a specific subset of that ability, specifically allowing verifiers to check that a secret (a result) is within a certain range without revealing the exact answer or the underlying information.

Offshift Dev Update, Early September 2021: Range Proofs

Offshift is working with Zokyo to develop the platform that will finally bring private finance, or PriFi, live.

Here’s a progress update for early September, 2021.

Zokyo continues to work on the cryptography for Offshift’s platform , specifically range proof generation and verification for shielding deposits and withdrawals.

A zero-knowledge range proof is a proof that allows us to verify that a secret is in a certain range without revealing it. Range proofs allow us to check that hidden values are correct. You might remember that we first mentioned using range proofs in the Offshift Yellowpaper , where we discussed how Bulletproofs work.

Offshift Dev Update, August 2021: Cryptography

Offshift is working with Zokyo to develop the platform that will finally bring private finance, or PriFi, live to Ethereum layer one.

Here’s a progress update for August, 2021.

Over the past few weeks, Zokyo has been working on one of the most critical pieces of the Offshift PriFi platform: the cryptography.

The team has been developing features for both generating and verifying the cryptographic proofs.
