Here is a glossary of terms related to the KILT Protocol:
W3C: Self-Sovereign Identity (SSI)
Decentralized Identifiers (DID)
Stands for Decentralized Identifier, a unique identifier for entities (people, organizations, or things) that can be anchored to a blockchain and provides verifiable digital identity. For example, did:kilt:4sxSYXakw1ZXBymzT9t3Yw91mUaqKST5bFUEjGEpvkTuckar. In KILT, identity is built by obtaining credentials linked to the DID. A DID can be used for people, machines, services and anything that identities can be built on.
DID authentication is the process of proving that an entity has control over a DID, typically by using a digital signature or other cryptographic mechanism.
DID communication refers to the use of DIDs to enable secure and decentralized communication between two or more parties, without the need for a central intermediary.
A DID controller is an entity that has control over a DID, such as the entity that created the DID or an entity that has been authorized by the DID owner to manage the DID.
A DID document is a JSON-LD document that contains information about a DID, including public keys, services, and other metadata.
A DID method is a set of rules and specifications for how a DID is created, resolved, and managed on a particular network or platform.
A DID resolver is a software component that can resolve a DID to a DID Document, which contains information about the DID, such as public keys, services, and other metadata.
A decentralized digital identity management system that enables individuals to own and control their identity information using secure digital technologies, such as blockchain. SSI eliminates the need for intermediaries and provides individuals with greater privacy, security, and control over their personal data. It is an emerging concept that has the potential to transform how identity is managed and verified across various sectors.
Verifiable credentials are digital credentials that can be used to prove claims about a person, organization, or thing, and are designed to be portable, interoperable, and privacy-preserving. Verifiable credentials are often associated with DIDs and can be stored and managed using a DID-based identity system.
KILT Protocol Specific Terms
The act of providing evidence or confirming the validity of the data within the claim, typically performed by a trusted attester.
An entity makes sure that certain statements are accurate. This entity examines claims made by other entities and only approves those that are true, issuing a certification. However, there may be dishonest attesters who approve false statements as well. Attesters play a critical role in building trust and establishing the authenticity of information and data shared between parties.
An individual or entity that asserts a claim or statement about their identity or qualifications. The claimer can use credentials to provide evidence of their claims, which can be verified by third-party entities or systems.
Claim Type (CType)
A specific type of claim that can be made about an individual, such as their education, work experience, or identity information. Each claim type has a defined set of attributes that must be provided to support the claims data type and structure. It can be used to generate verifiable credentials that can be shared with others. CTypes concept page for more details
A verifiable digital representation of a claim made by a claimer, which has been attested to by a trusted entity, such as an attester or issuer. It consists of a set of attributes that describe the claim and the proof of its validity, and can be shared with third parties to provide verifiable proof of the claim.
KILT Digital Identity
A self-sovereign identity that is owned and controlled by the individual or entity it represents. It consists of verifiable credentials that are issued by trusted entities, such as attesters, and can be used to prove claims about the individual or entity's identity, qualifications, or other attributes.
The native token of the KILT blockchain used for paying for attestations and DIDs. It can also be used for governance, staking, transaction fees and as a means of exchange on the network.
An open-source blockchain protocol for issuing self-sovereign, and verifiable credentials for Web3, the next generation of the Internet. KILT’s mission is to return control over personal data to its owner, restoring privacy to the individual.
Request for Attestation
Entities that are trusted to issue or verify claims on the KILT network, such as governments, educational institutions, or professional organizations.
A market that operates on trust and reputation in addition to financial incentives, where buyers and sellers exchange goods or services based on established reputation through digital platforms. While trust markets offer benefits such as reducing the need for intermediaries, they also face challenges that need to be addressed to maintain trust and fairness in transactions.
Transport-Agnostic Messaging Layer
A messaging system that is not dependent on any particular communication protocol or technology. It allows different systems or applications to communicate with each other regardless of the underlying transport protocol used, providing a standardized way of exchanging messages across different platforms and technologies.
A person, organization, or system that checks the validity and authenticity of an individual's credentials or qualifications. Verifiers play a critical role in building trust and ensuring that credentials are accurate and reliable.
A type of distributed ledger technology that allows multiple parties to have a synchronized, transparent, and immutable record of transactions. It uses cryptographic techniques to secure and verify transactions, and it does not require a central authority or intermediaries.
A network of computers or nodes that operate without a central authority or control. In a decentralized network, each node has equal control over the network, and decisions are made through a consensus mechanism, rather than by a single entity or group.
Distributed Ledger Technology (DLT)
A type of digital database that stores information across a network of computers or nodes. It allows multiple parties to have a synchronized, transparent, and immutable record of transactions, without the need for a central authority or intermediaries.
A transaction that originates from an external account and affects the state of the blockchain. It can be used to execute actions on the network, such as transferring funds, making governance decisions, use functionality of the parachain or interacting with smart contracts.
