Abstract

This document specifies the policy module of the Fusion Chain.

The policy module is responsible for storing policies and do verification checks of transactions that include a policy. A policy represents a set of conditions that need to be met in order to successfully verify a transaction's policy. Submitting a transaction with a policy does result in actions for eligible owners of the respective workspace.

Concepts

Policy

The policy language describes an ambitious wallet policy language, with a compiler and an on-chain verifier. Policies can refer to individual signatures (@Trader1), threshold signatures/policies (any n […]), native currencies, accounting currencies, oracles, ZK proofs and more.

State

Currently, the policy module does not store any state by itself.

Msg Service

The policy module currently does not expose any messages to be submitted.

Client

CLI

A user can query and interact with the policy module using the CLI.

Query

The query commands allow users to query policy state.

fchain query policy --help

Verify

The verify command allows users to query for the state of a policy to a given payload.

fchain query policy verify [policy] [payload] 

Example Output:

TBD

gRPC

A user can query the policy module using gRPC endpoints.

Verify

The verify command allows users to query for the state of a policy to a given payload.

fusionchain.policy.Query.Verify

Example:

grpcurl -plaintext localhost:9090 fusionchain.policy.Query.Verify

Example Output:

TBD

REST

A user can query the policy module using REST endpoints.

Verify

The verify command allows users to query for the state of a policy to a given payload.

/fusionchain/policy/verify/{policy}/{payload}

Example:

curl localhost:1317/fusionchain/policy/verify/{policy}/{payload}

Example Output:
