System Specification

Layers of a Model

Use-Case

Application

Platform

Infrastructure

Scaling

Define scaling scenarios with number of organisations, orderers and nodes.

Peak load

Model common or critical load scenarios.

Failures

Understand how the system will behave if specific servers fail.

Network degradation

Improve risk management by analysing critical network events.

Smart contract

Specify the set of contracts that define the business model governing the transactions on the distributed ledger (e.g., the number of participants that must agree on every ledger update).

Client

Specify the logic of the client application that defines the workload (i.e., a set of timestamped transactions to be sent to the distributed ledger).

Transactions

Specify the transaction types (e.g., queries and updates) and parametrise them (e.g., size).

Enterprise Blockchain Platform

Choose between different blockchain platforms, such as Hyperledger Fabric, Quorum and Corda

Consensus algorithm

Understand how different consensus algorithms, such as Raft and PBFT, change the system’s behavior.

Governance model

Decide on the structure of the consortium (i.e., the participants and their roles within the blockchain).

Cloud provider

Chose on which cloud providers (e.g., AWS, Google, Azure) the system will run on.

Geographical spread

Define or test for different geographical distributions.

CPU

Specify the type of CPUs (e.g., frequency, cores) on each host.

Interconnect network

Specify the properties of the network connecting the hosts (e.g., topology, bandwidth, latency)

TCP/IP

Fine tune the communication protocol (e.g., choose the TCP window size).
