Project Introduction

KILT is an open-source fat blockchain protocol for issuing claim-based, revocable and verifiable credentials for Web 3.0. It allows users to claim arbitrary attributes about themselves, have them attested by trusted entities, and store the claims as self-sovereign credentials. The protocol offers a simple JavaScript SDK so useful applications can be built without requiring any blockchain development skills.


The idea of the open-source KILT Protocol was born in Spring 2018 after an intense period of research and creative exchange. One year later the first testnet went live. In January 2021 KILT launched on Rococo, the parachain testnet, and KILT will participate in the first Kusama parachain auctions when they occur. We aim to start our mainnet on Kusama shortly after securing a parachain slot. KILT also anticipates the development of a Kusama to Polkadot bridge, which would enable us to provide the KILT functionality to Polkadot parachain projects.

Key Features and Highlights

KILT provides a base layer for verifiable credentials in the Web 3.0 world. We’re building a permissionless trust infrastructure for real-world business cases like our DeFi collaboration with Polkadex and Fractal, DNA testing with Degenics, and  upcoming projects in gaming and climate change. KILT also partnered with government entities including Germany's federal energy agency (DENA) to build a national digital registry for distributed energy resources. KILT is also part of GAIA-X project, initiated by the German Federal Ministry for Economic Affairs and Energy, to build a European alternative to centralized cloud solutions. 

Self-sovereign Data and Identity: The protocol uses three peer-to-peer roles to maintain and verify Trust inside the network: Claimer, Attester and Verifier. Claimer can be an object, individual or organization. Attester is a trusted party which confirms a claim to make sure evidence Claimer provides is correct. Last but not least - the Verifier, Verifier link Claimers with Attesters by creating a demand in the chain. A verifier receives credentials from a Claimer to verify the claims. For instance, a passport holder can be thought of as the Claimer, the issuing government as the Attester, and the border control office as the Verifier.

Software Development Kit (SDK): KILT provides a JavaScript SDK. JavaScript is a very very popular programming language which has a large community. Thus, it is very easy for developers to get used to it.

Polkadot Liquidity Mechanism (Polimec): Polimec is an open-source blockchain system designed to help getting liquidity into Polkadot based projects that have not been ready yet to sell transferable currencies on their own technology. It is a concept like the ERC20 Smart Contract mechanism but for issuing pre-currencies on Polkadot or Kusama as it enables Polkaverse projects to issue transferable pre-coins before go-live of their mainnet.
