Blockchain DAML runtime and Aerospace Traceability DApp


To build completely custom solutions for distributed ledgers, DAML models can be defined using the DAML SDK and deployed to the EFPF distributed ledger. Such solutions are also portable to other platforms.

The distributed ledger backend system is formed by Hyperledger Sawtooth nodes that use a permissioning system for granting writing rights to the EFPF users. The network is consortium based and all the nodes must validate every transaction and come to a consensus in order to accept it.

EFPF are building DAML models for traceability in the Aerospace domain, to be deployed and run on the EFPF blockchain servers. This model will be available to modify and extend for Open Call participants. The UI components will also be available as modules to re-use.
