Introduction to NomosDA

NomosDA provides a mechanism that guarantees that all data from Nomos zones are accessible and verifiable by every network participant.

Why We Chose KZG for NomosDA

We decided on the KZG scheme as the PCS for NomosDA, for reasons that will be explained in this conclusion to the PCS series.

FRI-based Commitments for Data Availability

The FRI scheme is renowned as a cornerstone of STARKs and can also serve as the basis for a polynomial commitment scheme using the DEEP-FRI method.

Inner Product Arguments for Data Availability

Inner Product Arguments for Data Availability

IPAs have been proposed for use in data availability sampling due to several key advantages over the more popular KZG scheme.

Dispatches from Thailand: Nomos Offsite V

On the week of November 3rd to 10th, the Nomos team gathered together in a picturesque villa on the outskirts of Bangkok, Thailand.

KZG Commitments for Data Availability

KZG Commitments for Data Availability

The KZG scheme was designed to reduce communication costs. This scheme is therefore a popular choice for use in data availability layers.

Commitment Schemes for Data Availability

Commitment Schemes for Data Availability

Polynomial commitment schemes play a vital role in the DA process by allowing a prover to commit to a polynomial and later provide proofs that specific evaluations of that polynomial are correct.

Preventing Wealth Concentration in PoS Systems: The Role of Stake Relativisation

Preventing Wealth Concentration in PoS Systems: The Role of Stake Relativisation

The recent transition of DarkFi from the PoS-based Ouroboros Crypsinous protocol due to wealth concentration findings motivated us to investigate the matter. We found that wealth concentration does not emerge from a PoS system driven by Crypsinous leader election function if certain conditions are met. In our previous article, we

Preventing Wealth Concentration in PoS Systems: The Role of Fork-Choice Rule and Stake Relativisation

While Proof of Stake (PoS) systems are often praised for their scalability and energy efficiency, centralisation concerns have drawn criticism about the system. Beyond centralisation, there are other issues to be concerned about, such as the possibility of wealth concentration and self-censorship. These can seriously jeopardise the fundamental principles of
