Term | Status | Definition |
Application | Centralized web and/or mobile software (front-end and/or back-end); may also include APIs. | |
| BLOCK | A block contains one or more transactions. | |
| Blockchain | A block contains an ordered set of transactions. It is cryptographically linked to the preceding block, and in turn it is linked to be subsequent blocks. The first block in such a chain of blocks is called the genesis block. Blocks are created by the ordering service, and then validated and committed by peers. | |
| Chain | The ledger’s chain is a transaction log structured as hash-linked blocks of transactions. Peers receive blocks of transactions from the ordering service, mark the block’s transactions as valid or invalid based on endorsement policies and concurrency violations, and append the block to the hash chain on the peer’s file system. | |
| Chaincode | Embedded logic that encodes the rules for specific types of network transactions. | |
DApp | Decentralized application - Whole or part of logic on a decentralized network; built on a peer-to-peer network like a blockchain; May have their own blockchain. | |
Initiatives | Groups of stakeholders collaborating to educate, develop pilots, & set policy. | |
Blockchain Platform | A decentralized, distributed, immutable ledger. | |
Project | Implementation of an Application, DApp, or Intermediary System. | |
Intermediary System | Standard or specification for data and procedure that may include libraries, protocols, applications; is not a blockchain in and of itself. | |
Private Consortium | Organization members collaborating to set standards, governance, development, and hosting of a private blockchain and its related applications. | |
Public Permissioned Consortium | Organization members collaborating to set standards, governance, development, and hosting of a public permissioned blockchain and its related applications. | |
| Channel | Private blockchain overlay that allows for data confidentiality and isolation. Channels are defined by a Configuration Block | |
| Configuration block | Block that contains the configuration data that defines members and policies for a system chain or channel. | |
| Consensus | General agreement that allows to confirm the correctness and the order of the set of transactions of a specific block. | |
| Smart contract | Decentralized, immutable and deterministic protocols that provide automation in blockchain solutions and allow to remove third-parties and let peer-to-peer interactions. Smart contract activities can be verifiedOnce agreed between the parties and deployed on a distributed ledger, their activities and outcomes can be verified, so they can be trusted by all stakeholders. | |
| Genesis block | First block of a block chain, that initializes the ordering service. | |
| Transaction | A transaction is created when a chaincode is invoked from a client application to read or write data from the ledger. | |
| Smart contract | Code – invoked by a client application external to the blockchain network – that manages access and modifications to a set of key-value pairs in the latest values for all keys included in the chain transaction log via transactions. |
Person | A human being, alive or deceased, as recognized by each jurisdiction’s legal definitions. |
Organization | An organized group of one or more people with a particular purpose. |
Role | People have roles in Organizations for specific periods of time. |

PII | Personally Identifiable Information is any item, collection, or grouping of information about an individual that is maintained by an organization, including identifying information, education, financial transactions, medical history, Social Security Numbers, and criminal or employment history. |
Personal Information | PII, demographics, and linked event information. Some information becomes personal in context (such as small group size aggregates). |
Learner Information | Information about a learner. |
Privacy Rights | Rights of a person to control access to and use of their personal information. More formal definition: “the right of a person to be free from intrusion into or publicity concerning matters of a personal nature” |
Authentication | Actions and mechanisms that can authenticate the identity of a person that includes information about an authentication provider, the login identifier used to authenticate a person's identity, and other information related to authentication of a person’s identity. |
Authorization | The authority to access to data or services to authorized entities. |
Access Control | The protocols in a system that limit access to data or services to authorized entities. Information about a data system or application that an authenticated person or system may access |
Self-sovereign identity | An identity system architecture based on the core principle that Identity Owners have the right to permanently control one or more Identifiers together with the usage of the associated Identity Data |
Information Security | Systems of controls designed to enforce privacy access controls and operational continuity. |
Data Stewardship/Processor | Responsibility to have proper security for privacy access controls. |
Trust | A person or systems ability to rely on something from another. Fiduciary trust can be delegated from one entity to another. |
Competency Definition | An information resource that includes a statement that describes a capability or behavior that a person may learn or be able to do within a given situation and environment along with definitions of the potential levels of mastery and metadata related to that statement |
