Member Roles


Membership provides various roles that differ in terms of authorisation and interaction possibilities. These are defined and described below.


In order to be able to implement the structure in the consortium, different roles are required in order to be able to fulfil the authorisations and tasks that one receives as a member. The roles can be used to shape the decision-making process and thus enable targeted weighting. In addition, authorisations can also be granted for tasks.


The following roles are taken from the Hyperledger Fabrics glossary. These are generally defined and are suitable as an initial orientation for a permission blockchain network. The exact roles required depend on the application area of the respective blockchain. This list of roles is not exhaustive and should be adapted to the respective use case. These descriptions can also be adapted as desired for the respective purpose.


Chain Member

Entities that do not participate in the validation process of a blockchain network, but help to maintain the integrity of a network. Unlike Chain transactors, chain members maintain a local copy of the ledger.

Chain Transactor

Entities that have permission to create transactions and query network data.

Chain Validator

Entities that own a stake of a chain network. Each chain validator has a voice in deciding whether a transaction is valid, therefore chain validators can interrogate all transactions sent to their chain.

Chain Auditor

Entities with the permission to interrogate transactions.


Solution User

End users are agnostic about the details of chain networks, they typically initiate transactions on a chain network through applications made available by solutions providers. Roles: None

Solution Provider

Organizations that develop mobile and/or browser based applications for end (solution) users to access chain networks. Some application owners may also be network owners. Roles: Chain Transactor

Network Proprietor

Proprietor(s) setup and define the purpose of a chain network. They are the stakeholders of a network. Roles: Chain Transactor, Chain Validator

Network Owner

Owners are stakeholders of a network that can validate transactions. After a network is first launched, its proprietor (who then becomes an owner) will invite business partners to co-own the network (by assigning them validating nodes). Any new owner added to a network must be approved by its existing owners. Roles: Chain Transactor, Chain Validator

Network Member

Members are participants of a blockchain network that cannot validate transactions but has the right to add users to the network. Roles: Chain Transactor, Chain Member

Network Users

End users of a network are also solution users. Unlike network owners and members, users do not own nodes. They transact with the network through an entry point offered by a member or an owner node. Roles: Chain Transactor

Network Auditors

Individuals or organizations with the permission to interrogate transactions. Roles: Chain Auditor
